Answer:
1. x = 21
2. x = 19
Step-by-step explanation:
Since the interior angles of all quadrilaterals add up to 360, all we have to do is add them up and set them equal to 360. Combine like terms and we get
7x + 213 = 360
Which further turns to 7x = 147
So x = 21
For the second problem, it's the same thing
By the end we get 2x + 8 = 46
2x = 38
x = 19
Hope this helps
A toy company needs to profit at least $500 from selling cars and trucks. A car can make a profit $2 while the truck can $3 profit.
let x be the number of cars
let y be the number of truck
If 200 resources for the car per week, we have:
Profit = $2x + $3y
$500 = $2*200 + $3*y
$500 - $400 = $3y
100 = 3y
y =100/3 = 33.33
The number of trucks needs to produce per week is at least 34 pieces.
X = 8/3
I hope this helped!
Answer:
$88
Step-by-step explanation:
To find the increase of $80 by 10%, find 10% of $80 then add it by the original amount
10% of 80=80*0.1=$8
The original amount=$80
Total amount=$80+$8=$88
Answer:
y-coordinate of midpoint of line segment joining the endpoints (0,0) and (0,15) is 7.5
Step-by-step explanation:
Given two end points of line segment that are (0,0) and (0,15). If we have to find the y-coordinate of midpoint of a vertical line segment then we apply mid point formula.
The Midpoint formula is used when one is need to find the exact center point between two given points.
The mid point M of line segment 
and 
can be calculated as
Mid point of line joining the end points (0,0) and (0,15) is
=M(0,7.5)
Hence, y-coordinate of midpoint of line segment joining the endpoints (0,0) and (0,15) is 7.5
