Answer equal to 3 because 3+4 =8-5 equal 3
Answer:
(-4, 2)
Step-by-step explanation:
4x+2y=-12
3x+y=-10
Start by dividing the first equation by 2 to simplify it...
2x+y=-6
Then, subtract -2x from both sides to isolate y...
y=-2x-6
Substitute -2x-6 for y in the second equation...
3x-2x-6=-10
Combine like terms...
x-6=-10
Add 6 to both sides
x-6+6=-10+6
x=-4
Plug -4 in for x to solve for y:
3(-4)+y=-10
-12+y=-10
Add 12 to both sides
-12+12+y=-10+12
y=2
(x,y)=(-4,2)
Answer:
the quotient x minus 0.3 is equal to 1.7
Step-by-step explanation:
Answer:
30
Step-by-step explanation:
All the degrees of a triangle should add up to 180 degrees.
D = F
D and F are not equal to 90.
If E = 30, D and F both equal 75.
75(2) + 30 = 180.
C; a percent is out of 100. All you have to do is change the denominator into 100. Since 5x20=100, you have to multiply 3/5 top and bottom by 20. Your product should be 60.
