Answer:
m = -1 is your answer.
Step-by-step explanation:
What you do is you have to get m by itself.
<em>m = -(4 + m) + 2</em>
<em>m = -4 + -m + 2</em>
<em>2m = -2</em>
m = -1 is your answer.
You should just multiply the first equation by 3 so you will have :
3 ( 3x+y= 7 ) ⇒ 9x + 3y = 21 so now you have the missing values and they are 3 and 21 :))

Answer:
Step-by-step explanation:
When we scale an object by a scale factor, the side lengths become the scale factor times bigger than the previous sides. Therefore, with a scale factor of 6, the side lengths would be multiplied by 6.

3 : 1 : 4
3 + 1 + 4 = 8
For ratio 3 = 3/8 * 48 = 18
For ratio 1 = 1/8 * 48 = 6
For ratio 4 = 4/8 * 48 = 24
So 48 in ratio 3 : 1 : 4 = 18, 6, 24
Answer:
46 yards
Step-by-step explanation:
let x = number of lawns mowed per month
let y = number of full landscape maintenance service
y = 2x
100x + 130y = 8,280
100x + 260x = 8,280
360x = 8,280
x = 8,280 / 360 = 23
Melissa provides only lawn service to 23 yards and full landscape maintenance service to 46 yards.
