To find the answer to each of these equations, we need to substitute the given value for the variable and perform the necessary calculations.
1. For the equation 8q + 6; q = 2, we substitute q = 2:
8(2) + 6 = 16 + 6 = 22.
Therefore, the answer is 22.
2. For the equation 9 + 4g; g = -3, we substitute g = -3:
9 + 4(-3) = 9 - 12 = -3.
Therefore, the answer is -3.
3. For the equation 7x - 7; x = 4, we substitute x = 4:
7(4) - 7 = 28 - 7 = 21.
Therefore, the answer is 21.
4. For the equation 12p + 4; p = 1.5, we substitute p = 1.5:
12(1.5) + 4 = 18 + 4 = 22.
Therefore, the answer is 22.
5. For the equation 5w + 10 = 40, we need to solve for w.
Subtracting 10 from both sides of the equation:
5w = 40 - 10 = 30.
Dividing both sides by 5:
w = 30 / 5 = 6.
Therefore, the answer is 6.
6. For the equation 4y - 12 = 60, we need to solve for y.
Adding 12 to both sides of the equation:
4y = 60 + 12 = 72.
Dividing both sides by 4:
y = 72 / 4 = 18.
Therefore, the answer is 18.
7. For the equation 10k + 5 = 65, we need to solve for k.
Subtracting 5 from both sides of the equation:
10k = 65 - 5 = 60.
Dividing both sides by 10:
k = 60 / 10 = 6.
Therefore, the answer is 6.
8. For the equation 2b - 15 = 33, we need to solve for b.
Adding 15 to both sides of the equation:
2b = 33 + 15 = 48.
Dividing both sides by 2:
b = 48 / 2 = 24.
Therefore, the answer is 24.
9. For the equation 3d + 18 = 21, we need to solve for d.
Subtracting 18 from both sides of the equation:
3d = 21 - 18 = 3.
Dividing both sides by 3:
d = 3 / 3 = 1.
Therefore, the answer is 1.
