The answer is C.......Sports Stamps = 4 , Holiday Stamps = 2 , Presidents Stamps = 8. He said 4 times as many presidents than holiday. So the number of presidents stamps is the product of the holiday stamps times 4. 4 times 2 is 8. Add them all together
Expand
4x - 28 = 0.3x + 0.6 + 2.11
Simplify 0.3x + 0.6 + 2.11 to 0.3x + 2.71
4x - 28 = 0.3x + 2.71
Add 28 to both sides
4x = 0.3x + 2.71 + 28
Simplify 0.3x + 2.71 + 28 to 0.3x + 30.71
4x = 0.3x + 30.71
Subtract 0.3x from both sides
4x - 0.3x = 30.71
Simplify 4x - 0.3x to 3.7x
3.7x = 30.71
Divide both sides by 3.7
x = 30.71/3.7
Simplify 30.71/3.7 to 8.3
<u>x = 8.3</u>
Answer:
x = 7
Step-by-step explanation:
QY = 5x
YZ = 18
QZ = 53
Thus:
QY + YZ = QZ (segment addition postulate)
5x + 18 = 53
5x = 53 - 18 (subtraction property of equality)
5x = 35
Divide both sides by 5
x = 7
Answer:
10,000
Step-by-step explanation:
The base for a normal log is 10. You raise the base by the answer, which is 4. 
is 10,000.
24.68 x .15 = 3.70
3.70 would be the tip
