Answer:
x = 24
Step-by-step explanation:
a^2 + b^2 = c^2
7^2 + b^2 = 25^2
49 + b^2 = 625
<u>-49 -49</u>
b^2 = 576
square root them
b = 24, or x = 24

Answer:
t = 5(2) + 3
Step-by-step explanation:
You want the t on the outside because that is what you are trying to figure out.

Answer:
x ≤ 2
Step-by-step explanation:
Most of the properties of equality also apply to inequalities. The exception is multiplication (or division) by a negative number. An equation can be multiplied or divided by any number you like (except division by 0) and it will remain true. <em>An inequality must have the relation symbol reversed when multiplying or dividing by a negative number</em>.
Here, we don't run into that issue, because we can solve this by dividing both sides by the coefficient of x, which is +3.
(3x)/3 ≤ 6/3
x ≤ 2 . . . . . . . simplify
Answer: 131 magazines per hour
Step-by-step explanation:
Peggy delivered 328 magazines in 2.5 hours.
To find out the rate at which she delivered these magazines, divide the number of magazines by the time taken to deliver them:

= 328 / 2.5
= 131 magazines per hour
