Problem 1) What value of x makes the equation below true? 7 + x = 84 A. 12 B. 77 C. 83 D. 91:

Problem 1) What value of x makes the equation below true? 7 + x = 84 A. 12 B. 77 C. 83 D. 91 Solve simple one-step equations using basic whole-number facts

How to solve There are 2 basic rules to a problem like this. Isolate the unknown on one side of the equal sign. Whatever action you perform must be performed on both sides of the equal sign. 7 + x = 84 Subtract 7 from both sides to isolate x 7 + x – 7 = 84 – 7 x = 77 The correct answer is Choice B, 77 :

Solve simple proportions within context:

Solve simple proportions within context Problem 2) Guafi selects 15 pieces of fruit. If 3 out of 5 of these fruit are bananas, b , how many bananas does Guafi select? 3 9 13 25

How to solve:

How to solve Facts provided There are 15 total pieces of fruit There are 3 bananas for every 5 pieces of fruit Write a formula that expresses those two statements 15 pieces of fruit, the bananas plus the other fruit, when 3 out of every 5 fruit is a banana. G-Zibo Tip – In a word problem, the word “is” means equals in the formula 15 (3/5) = b

How to solve:

How to solve There are 2 basic rules to a problem like this. Isolate the unknown on one side of the equal sign . In this case it already is. Whatever action you perform must be performed on both sides of the equal sign. 15 (3/5) = b Simplify the left side Multiply 3/5 times 15 3 x 15 = b 5 45 = b 5 9 = b Choice B is the correct answer

Translate two-step verbal sentences into algebraic equations:

Translate two-step verbal sentences into algebraic equations Problem 3) What algebraic equation represents “three times the difference of a number, x, and nine equals fifteen”? 9 x -3 = 15 3(9) – x = 15 9 – 3 x = 15 3( x – 9) = 15

How to solve :

How to solve The statement gives 3 times the difference of x and 9 3( x – 9) equals 15 the word “equals” determines where the equal sign goes, 15 on one side, everything else on the other 3( x -9) = 15 Choice D is the correct answer
