Answer:
5 × [5(-7)]
= 5 × (-35) ---- 5 × (-7) = -35
= -175
Y = 5x + 2
3x = y + 10
3x = y + 10
3x = 5x + 2 + 10
3x = 5x + 12
3x - 5x = 12
-2x = 12
x = -6
substitute x = -6 into y = 5x + 2
y = 5(-6) + 2
y = -30 + 2
y = -28
x = -6, y = -28
hope this helped, God bless!
Answer:
75th term = 443
Step-by-step explanation:

Answer:
4
Step-by-step explanation:
The area, a of the room is 8* 5.5
a = 44 sqaure feet
one square foot of tiles are sold in packages of 12
To get the number of packages needed, simply divide the area of the room by 12
This gives:
44/12 = 4
= 3.67 round up to the nearest whole number
= 4
Answer: x=4
Step-by-step explanation:
2x-3(x+4)=3x-4
distribute 2x-3x-12=3x-4
combine like terms 5x-12=3x-4
Move everything to one side 2x-8=0
Get x by itself 2x=8
Divide by 2 x=4
