by multiplying $2.52 by 4
Step-by-step explanation:
Answer:
-26= -9x + 10
-26 - 10= -9x
-36=-9x
-36:(-9)=x
4=x
Step-by-step explanation:
1. you pass +10 to the left in minus
2. you resolve what you've got on the left
then you pass the multiplying -9 to the left dividing
Answer:
Line f has the same slope, -4/3
Step-by-step explanation:
First find the the slope of line e
m = (y2-y1)/(x2-x1)
= (2-6)/(10-7)
= -4/3
Since the lines are parallel, they have the same slope
Line f has the same slope, -4/3
Height of wall = 8 feet
1 feet = 12 inches
⇒ Height of wall = 8 × 12 inches
⇒ Height of wall = 96 inches
We know that the 4 shelves are to be placed such that that the 5 spaces created decrease by 7 inches as we move up the wall
Let height of 1st space = h inches
⇒ Height of 2nd space = h - 7 inches
⇒ Height of 3rd space = h - 14 inches
⇒ Height of 4th space = h - 21 inches
⇒ Height of 5th space = h - 28 inches
Thickness of each shelf = 3/4 inch
⇒ Thickness of 4 shelves =
× 4 inches = 3 inches
So, Height of Wall = Height of 1st space + Height of 2nd space + Height of 3rd space + Height of 4th space + Height of 5th space + Thickness of 4 shelves
⇒ 96 = h + h - 7 + h - 14 + h -21 + h - 28 + 3
⇒ 95 = 5h - 70 + 3
⇒ 95 = 5h - 67
⇒ 5h = 162
⇒ h = 32.4 inches
So the first shelf is placed 32.4 inches from the floor
Answer:
x = -12
Step-by-step explanation:
m∡QRP = 180 - (80 + 43) = 57°
-6x + 51 + 57 = 180
-6x + 108 = 180
-6x = 72
x = -12
