b. 56 − 72 = x
c. 56 + x = 72
d. 56 + 72 = x
Answer:
C. 56 + x =72
Give your answer in its simplest form.
Answer:
a = √a b = √5 c = √10
ac/b = (√a)(√10)/√5
= √ 10 × a /√5
= √10a / √5
Rationalize the surd
√10a ×√5/(√5)²
= √50a /5
= 5√2a/ 5
= √2a
The final answer is √2a
Hope this helps
You need to substitute the given values into the ac/b equation. After substitization and simplification, the equation ac/b simplifies to √2.
The equation that we need to evaluate is ac/b, using the variables a, b, and c given in the question. So, substituting the given values, we get:
a * c / b = √a * √10 / √5
Since a is equal to √a, we can replace a with √a in the equation, so it then becomes:
√a * √10 / √5 = √(a*10) / √5
Since a is √a, a*10 is therefore √10, so the equation becomes:
√10 / √5
That simplifies to √2 in its simplest form.

How much would it cost altogether to ride 7 rides?
Answer:
equation: y=2.25x+5
a: 13 rides
b:$20.75 for 7 rides
explanation:
a: 35=2.25x+5
first subtract 5 from 5 and 35
30=2.25x
divide each side by 2.25
x= 13 1/3
can only go on 13 rides
b: y=2.25(7)+5
2.25×7=15.75
15.75+5=20.75
$20.75 for 7 rides
