Describe the steps you used to solve the equation and find the amount of carrie’s allowance. linear equation:   1/4 a + 1/3 a + 8 = 22

24

Step-by-step explanation:

Subtract 8 from 22 = 1/4a+1/3a=14

Add the fractions together =7/12a=14

Divide 14 by 7/12 and a=24

Sample Response:

First, the like terms had to be combined using the lowest common denominator (LCD). Then the subtraction property of equality was used to isolate the variable term. Finally, both sides of the equation were multiplied by the reciprocal of the coefficient to solve for a.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
