substitute x value into MON equation to find angle measure
you get 57 degrees
Add like terms. Like terms are terms that have the same variable.
<span>9x + 2y + 6 + 9y + 7 =
= 9x + 2y + 9y + 6 + 7
= 9x + 11y + 13
The coefficient of y is 11.
The constant is 13.

Answer: <em>Tara thinks correctly.</em>
Step-by-step explanation:
<em>Let's calculate the average value in sample A:</em>
<em>(4 × 70 + 5 × 100 + 6 × 125 + 7 × 135 + 8 × 70) ÷ 500 = 6,07 ≈ </em><em>6 hours</em>
<em>Let's calculate the average value in sample B:</em>
<em>(4 × 80 + 5 × 90 + 6 × 120 + 7 × 125 + 8 × 85) ÷ 500 = 6,09 ≈ </em><em>6 hours</em>
<em>So, Tara is correct in saying that the mean is 6.</em>
Answer:
x =7
Step-by-step explanation:
16:28=4:x
16*x=28*4
x=28*4/16
x=112/16
x=7
Answer:
25,600
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
Well, in order to solve these types of problems, you would divide by the percent.
For example {keep in mind this is reduced by 30%, making it 70%}:
17920/70=256
Then we would multiply that by 100 {making it 100%}:
256*100=25,600
And to check, we would multiply the original percentage by the number we just got.
25,600*0.7=17920
So you have your answer, 25,600
