Answer:
You would multiply the x component by -2
Step-by-step explanation:
(-2) (-2x-5y)=-2(-1)
4x+10y=2
4x+2y=8
set both equal to 4x
4x=2-10y
4x=8-2y
2-10y=8-2y
-6=8y
y=-6/8
y=-3/4
4x + 2(-3/4) = 8
4x=38/4
x=38/16
x=19/8
I Believe the mean would would 60 degrees Fahrenheit
Answer:
m∠1=66
m∠3=66
m∠4=114
Step-by-step explanation:
m∠1+m∠2=180
m∠1+114=180
m∠1=66
m∠1=m∠3
66=m∠3
m∠4=m∠2
m∠4=114
Answer:
0.4
Step-by-step explanation:
drawing a triangle with each side correspondent to each of its measurements all you are doing is dividing the side that you would want to find its scale factor of, which in this case you would take AB and DE and have AB/DE dividing that and getting 0.4 as its scale factor.
5 × (x + 12) = 80
5x + 60 = 80
5x = 20
x= 4
