Sample Question: Evaluate 9 150/300

• 18
• 3
• 81
• Answer Explanation: 9150/300 = 91/2 = square root of 9 = 3. In a problem with a rational exponent, the numerator tells you the power, and the denominator the root. However, in this problem the exponent can be reduced, so we should reduce that first. The exponent 150/300 = 1/2. So the problem becomes 9 to the 1/2 power. The denominator is 2 so we take the square root of 9 which is 3. The numerator is 1 so we raise 3 to the 1st power and the answer is 3.

## How To Solve Algebraic Expression

Polynomial Equations and Factoring – Grade 10 Test Preparation Questions

The purpose of solving an algebraic expression in an equation is to find the unknown variable. When two expressions are equated, they form an equation, and therefore, it becomes easier to solve for the unknown terms.

To solve an equation, place the variables on one side and the constants on the other side. You can isolate the variables by applying arithmetic operations like addition, subtraction, multiplication, division, square root, cube root, etc.

An algebraic expression is always interchangeable. This implies that you can rewrite the equation by interchanging the LHS and RHS.

Calculate the value of x in the following equation

5x + 10 = 50

Given Equation as 5x + 10 = 50

• Isolate the variables and the constants
• You can keep the variable on the LHS and the constants on the RHS.

5x = 50-10

## Domain: Grade 10 > > Geometry Circles

Sample Question: What is the translation rule and the scale factor of the dilation as Circle FCircle F ?

• 1/4
• 1/4
• 1/4
• Answer Explanation: The original circle F has its center at the point with a radius of 4 units. The translated/dilated circle F has its center at the point with a radius of 1 units. This means the center was translated up 10 units. As a transformation, this translation is written as . Circle F was also dilated by a factor of 1/4 because the radius was reduced from 4 units to 1 units. As a transformation, this dilation is written as 1/4. Putting the translation and dilation together, the rule is 1/4.

## Example Question #: Algebra

Let x be a number. Increasing x by twenty percent yields that same result as decreasing the product of four and x by five. What is x?

The problem tells us that increasing x by twenty percent gives us the same thing that we would get if we decreased the product of four and x by five. We need to find expressions for these two situations, and then we can set them equal and solve for x.

Let’s find an expression for increasing x by twenty percent. We could represent this as x + 20%x = x + 0.2x = 1.2x = 6x/5.

Let’s find an expression for decreasing the product of four and x by five. First, we must find the product of four and x, which can be written as 4x. Then we must decrease this by five, so we must subtract five from 4x, which could be written as 4x – 5.

Now we must set the two expressions equal to one another.

6x/5 = 4x – 5

Subtract 6x/5 from both sides. We can rewrite 4x as 20x/5 so that it has a common denominator with 6x/5.

0 = 20x/5 – 6x/5 – 5 = 14x/5 – 5

0 = 14x/5 – 5

Now we can add five to both sides.

5 = 14x/5

Now we can multiply both sides by 5/14, which is the reciprocal of 14/5.

5 = = x

Therefore,

Perimeter of equilateral triangle = a+a+a = 3a

## Algebraic Expression Explanation & Examples

Algebra is an interesting and enjoyable branch of mathematics in which numbers, shapes, and letters are used to express problems. Whether you are learning algebra in school or examining a certain test, you will notice that almost all mathematical problems are represented in words.

Therefore, the need to translate written word problems into algebraic expressions arises when we need to solve them.

Most of the algebraic word problems consist of real-life short stories or cases. Others are simple phrases such as the description of a math problem. This article will learn how to write algebraic expressions from simple word problems and then advance to lightly complex word problems.

6. Collect like terms and simplify the expression:

12m2 9m + 5m 4m2 7m + 10

Solution: Rearranging terms, we have:

12m2 4m2 + 5m 9m 7m + 10

= m2 + m + 10

= 8m2 + m + 10

= 8m2 + m + 10

7. Subtract 24ab 10b 18a from 30ab + 12b + 14a.

Solution: 30ab + 12b + 14a

= 30ab + 12b + 14a 24ab + 10b + 18a

= 30ab 24ab + 12b + 10b + 14a + 18a

= 6ab + 22b + 32a

8. Find the value of x2-5x+8, for x = 2.

Solution: Given: x2-5x+8

= 2 5 + 8

Simplify the following:$\left \left \div 4^$ I don’t know how to simplify this expression.

• 1$\begingroup$$8^=\Big^ =2^ =2^. And just as 8 is 2^3, so 16 is 2^4 and 4 is 2^2. \qquad$$\endgroup$

Hint: Use that$$4=2^2\qquad 8=2^3\qquad 16=2^4$$as well as these rules about exponentiation:$$^c=a^\qquad a^b\div a^c=a^$$

Note that:$$8^=\left^=2^$$$$16^=\left^=2^$$$$4^=\left^=2^$$

Since they are all raised to the same base  you can go ahead and apply the relevant exponential laws to simplify your expression. Namely $a^na^m=a^$ to simplify the numerator and $\frac=a^$ to further simplify the remaining expression.

## Domain: Grade 10 > > Functions Trigonometric Functions

Sample Question: In the unit circle, one can see that tan=1 . What is the value of cos?

• 2/2
• -1
• Answer Explanation:The trigonometric ratio of cosine is the ratio of the length of the adjacent side divided by the length of the hypotenuse. The length of the adjacent side is the xvalue in a point on the unit circle. The hypotenuse is the radius of the unit circle, so the hypotenuse is 1. Thus, the value of the cosine ratio of any angle in the unit circle is the xvalue of the point on the unit circle that corresponds to that angle. The trigonometric ratio of tangent is the length of the opposite side divided by the length of the adjacent side. The length of the opposite side is the yvalue in a point on the unit circle and the length of the adjacent side is the xvalue in a point on the unit circle. The hypotenuse is the radius of the unit circle, so the hypotenuse is 1. Thus, the value of the tangent ratio of any angle in the unit circle is the ratio yx from the point on the unit circle that corresponds to that angle. In this question, tan=1. This ratio is taken from the point that corresponds to the angle with a measure of 5/4 radians. Thus, using the information above, the value of cos is the same as the xvalue in the point .Therefore, the value of cos=2/2.

Sample Question: Rewrite x1/2 in radical form.

• x
• 1/x
• -x
• Answer Explanation: In a problem with a rational exponent, the numerator tells you the power, and the denominator the root. Since the problem is, x1/2, the denominator is 2 indicating we should take a square root and the numerator is 1 so we would raise that to the first power or there will be no exponent since an exponent of 1 is rarely used. That makes the answer the square root of x, written as x.

Sample Question: What value on the number line in the figure below divides segment EF into two parts having a ratio of their lengths of 3:1?

• -5
• -2
• -1
• Answer Explanation: Point E is at -7 on the number line in the figure, and pointF is at 1. Thus, the length of segment EF is 8. To divide the segment into two parts with a ratio of their lengths of 3:1, change the ratio to 3x:1x to allow variation in the location on the number line. Next, set the sum of the two parts equal to 8 and solve for x. 3x+1x=8 4x=8 x=2.Now, that you know that x=2, find 3x, which equals 6. Find the value on the number line by adding 6 to the position of point E. 7+6=1.The value on the number line that divides segment EF in a ratio of 3:1 is -1.

Answer Explanation: Use the formula for volume of a pyramid:

V=1/2.a.c.h

In this case the length is 15cm, the base is 10 cm in length, and the height is 9 cm. Therefore :

V=1/2.15.10.9=675cm3
