Answer:

1. -1

2. 7

3. 5

4. -328.5

5. 69

6. -216

Step-by-step explanation:

1. 2y+(13 - 9y) when y = 2

2(2)+(13-9(2)

4+(13-18)

4+ -5

= -1

2. 3 + 6b ÷ 3 when b is = 2

3+6(2)÷3

3+12÷3

3+4

=7

3. 16p - 32q + 5 when p = 2 and q=1

16(2)-32(1)+5

32-32+5

=5

4.2b³+4g-7a; b=2, g=-3, a=47.5

2(2)³+4(-3)-7(47.5)

2(8)-12-332.5

16-12-332.5

4-332.5

-328.5

5. v-4x + 8 a²; v = 5 and x =2, a = 3

5-4(2)+8(3)²

5-8+8(9)

5-8+72

-3+72

= 69

6. 4r +5xr - 12x²; r = -4 and x = -5

4(-4)+5(-5)(-4)-12(-5)²

-16+5(20)-12(25)

-16+100-300

84-300

=-216
