Answer:
t = 14
Step-by-step explanation:
log (7t + 2) = 2
Raise each side to the power of 10
10 ^log (7t + 2) =10^ 2
7t+2 = 100
Subtract 2 from each side
7t+2-2 = 100-2
7t = 98
Divide each side by 7
7t/7 = 98/7
t = 14
31 minus 7 is 24. 24 divided by 3 is 8. The number is 8.
Set up a proportion.
10/5=x/7
5x = 70
x = 14
since ΔCDW similar to ΔUVW, then
UW/CW = UV/CD
UW = CW•UV/CD
CU+CW = CW•UV/CD
CU = CW•UV/CD - CW
= 26•132/24 - 26
= 143 - 26
= 117
Answer:
If I am right you have to multiply 8 by 30 and than divide it by 12 the answer it will give you is x
