Answer:
x = 6
Step-by-step explanation:
5 (x - 3) + 2 = 5 (2x - 8) - 3
<em>remove the parenteses</em>
5x - 15 + 2 = 10x - 40 - 3
<h3><em>calculate</em></h3>
5x - 13 = 10x - 43
<h3><em>move the terms</em></h3>
5x - 10x = -43 + 13
<h3><em>collect like terms </em></h3><h3><em>calculate</em></h3>
-5x = -30
<h3><em>divide both sides</em></h3><h3><em /></h3>
Solution
x = 6
Answer:
part A 210 Part B 4.4
Step-by-step explanation:
PART A 42 TIMES 5 210
that will be the rate she ran.
PART B 1.1 times 4 that will be the minute.
Well 106 divided by 7 is 15 so 15 times 7 is 106
It depends on the given information.
McKenzie's work is correct if the two short sides are given as 5 and 13.
Cara's work is correct is almost correct if 5 is one leg, and 13 is the hypotenuse. The exact answer is 12, but she wrote it as approximately equal. That's her only problem.
By the way, Ddssaa122: when posting questions, the power of a number is written as 5^2 and not 52. If you copy and paste, please make sure you add the caret sign to indicate a power, or else you will suffer by getting a wrong answer. 5^2=5*5, 52=4*13, so they are not the same.
