Answer:
METHOD 1:
5x+7(x+1)=5x-21
5x+7x+7=5x-21
12x+7=5x-21
12x-5x=-21-7
7x=-28
x=28/7
x=4
METHOD 2:
5x+7(x+1)=5x-21
5x+7(x+1)=5x-21-5x
7(x+1)=-21
7x+7=-21
7x=-28
x=4
Step-by-step explanation:
METHOD 1:
5x+7(x+1)=5x-21
5x+7x+7=5x-21
12x+7=5x-21
12x-5x=-21-7
7x=-28
x=28/7
x=4
METHOD 2:
5x+7(x+1)=5x-21
5x+7(x+1)=5x-21-5x
7(x+1)=-21
7x+7=-21
7x=-28
x=4
I think the answer would be 44,000,000 because if you roundthe 951 it goes to 1,000
Hi there!
10. the number: x
4 more = addition
5 times = multiplication
less then 54 = 54 >
4 + 5x = <54
Hope this helps!
Answer:
Step-by-step explanation:
x3-y=26d
3x-7=26d
3x=26d=y
x=(26/3)d+(1/3)y
------
x3-y=26
3x-y=26d
-y=26d-3x
y=-26d+3x
-------
x3-y=26d
3x-y=26d
26d=3x-y
d=(3/26)x-(1/26)y
-------
NOT SURE THOUGH
4x + y = -1
y = -4x -1
slope of the parallel line
m = -4
General equation of the parallel line
y = -4x + c
if this passes through (5,0)
0 = (-4*5) + c
c = 20
so the equation is
y = -4x + 20
