Answer:
Step-by-step explanation:
Do substitution by first writing an equation 15c + 29a=175 when you get your answer either substitute it in your other equation which would be 21c+27a=177, if you found c(Children) in your first equation substitute it in 21 by multipying if you found a do the same thing.
3x+2= 32
because if you multiply x by three and then add two to the product, you should get 32.
Answer:
1.4650 (the first option in the list of possible answers)
Step-by-step explanation:
Start by isolating the exponential expression on one side of the equal sign, thus subtracting 2 from both sides:

Now, in order to solve for "x", we need to lower the exponent, and for that purpose we use logarithm base "3":

In order to find this logarithm, we use the change of base formula:

which rounded to four decimals gives: 1.4650

Answer:
x = 28, y = 34
Step-by-step explanation:
70 + 4x - 2 = 180
110 = 4x - 2
112 = 4x
x = 28
(y + 9) + (y - 1) + 2(y - 4) = 136
4y = 136
y = 34
