**Texas Go Math Grade 7 Module 7 Are You Ready? Answer Key**

**Evaluate each expression.**

Question 1.

2(5) + 11 __________

Answer:

2(5) + 11 = 10 + 11 Multiply 2 by 5.

= 21 Add 11 to this product.

2(5) + 11 = 21

Question 2.

9(6) – 5 __________

Answer:

9 (6) – 5 = 54 – 5 Multiply 9 by 6.

= 49 Subtract 5 from this product

9(6) – 5 = 49

Question 3.

4(12) – 15 __________

Answer:

4 (12) – 15 = 48 – 15 Multiply 4 by 12.

= 33 Subtract 15 from this product.

4(12) – 15 = 33

Question 4.

-6(2) + 13 ___________

Answer:

-6(2) + 13 = -12 + 13 Multiply -6 by 2.

= 1 Add 13 to this product.

-6(2) + 13 = 1

Question 5.

7(-4) – 8 ____________

Answer:

7(- 4) – 8 = -28 – 8 Multiply 7 by -4.

= -36 Since both numbers are negative, they are added together with the -“ sign.

7(-4) – 8 = -36

Question 6.

-2(-5) + 7 ____________

Answer:

-2(- 5) + 7 = 10 + 7 Multiply -2 by -5.

= 17 Add 7 to this product.

-2(-5) + 7 = 17

**Find a rule relating the given values.**

Question 7.

Answer:

Set the equation for x = 1, y = 3. For all the others apply the same rule.

1 ∙ z = 3

Notice that this variable z is 3 because;

1 ∙ 3 = 3

Therefore the rule for the given value is:

y = x ∙ 3

Question 8.

Answer:

Set the equation for x = 1, y = 9. For all the others apply the same rule

1 + z = 9

Subtract one from each side.

z = 1 – 1 + z = 9 – 1 = 8

Therefore the rule for the given value is:

y = x + 8

Graph point A(4, 3). Start at the origin. Move 4 units right. Then move 3 units up.

**Graph each point on the coordinate grid above.**

Question 9.

B(9, 0)

Answer:

For graphing a point A = (9, 0) starting from the origin move 9 units right

Question 10.

C(2, 7)

Answer:

C = (2, 7)

Starting from the origin move 2 units right and than move 7 units up.

Question 11.

D(0, 5)

Answer:

D = (0, 5)

Starting from the origin move 5 units up.

Question 12.

E(6, 2)

Answer:

E = (6, 2)

Starting from the origin move 6 units right and then move 2 units up.
