Answer:
20
Step-by-step explanation:
To solve this you have to make a system of equations.
Since the father and son's age sum up to 60, the first equation will be:
f + s = 60
Secondly, since the father's age is 5 times the age of the son 6 years ago the equation will be:
6 - (5s) = f
Now, you have to solve the first equation to let it equal to s
f + s = 60
f = 60 - s
Plug in
6 - 5s = 60 - s
+s +s
6 - 4s = 60
-6 -6
---------------------
-4s = 54
----- -----
-4 -4
s ≅ 14
14 + 6 = 20
First, you plug in 3.50 for d. Then, you multiply 5 and 3.50 and get 17.50. After that, you subtract 17.50 from 42 , and you get 24.50. That means that Jamie will have $24.50 of her allowance left.
20 dived by 60 equals 0.3
Answer: 22 + 8x ≤ 60
Step-by-step explanation: She has to spend 22 dollars on jeans, so $22 will be added to the initial amount. The <em>x </em>will be the number of t-shirts and then the cost of <em>x </em>t-shirts will be <em>8x</em>. Putting this into inequality form will result in <u>22 + 8x ≤ 60</u>
