16 - -15 = 31 (negative - negative = positive)
hope this helps! :)
Answer:
show range that is between 3 and 10
Step-by-step explanation:
The answer is -6 < x < 9.
can u mark me as brainliest?
Let x= measure of angle 1
Let y= measure of angle 2
This is solving a system of equations
3x=30+ 5y which can also be written
3x-5y=30, and
2x+2y=180
There are a few ways to solve this, like solving for x in one of the equations and plugging it in for x in the other equation, but here is another way:
2(3x-5y)=2*30
3(2x+2y)= 3*180
6x-10y=60
6x+6y=540, and now subtract to get rid of x
0-16y=-480
Y=30
Plug it back in to either equation and you get x=60
Answer:
<u>D. 0.92t, is indeed a correct answer, but probably B or E are not correctly written. The second correct way is t - 0.08t.</u>
Step-by-step explanation:
If the farmer recently sold 8% of the original acreage of his plot and t is the original acreage, therefore:
8% = 0.08
Thence, the expressions to describe two ways to find the new acreage are:
t - 0.08t
t - 0.08t = 0.92t
<u>D. 0.92t, is indeed a correct answer, but probably B or E are not correctly written. The second correct way is t - 0.08t.</u>
