Answer:
x=17
Step-by-step explanation:
53+(2x+3)=90
Answer:
7/2 is the slope and 5 is the y-intercept
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
7x-2y=-10
subtract 7x on both sides
-2y=-7x-10
divide by -2 on both sides
y=(7/2)x+5
7/2 is the slope and 5 is the y-intercept.
Answer:
{(12-4) + (15-8)}x = 65
Step-by-step explanation:
The amount Amber earns per week
12-4
The amount Nathan earns per week
15 -8
The total amount per week they earn together
(12-4) + (15-8)
Multiply by x weeks
{(12-4) + (15-8)}x
Set this equal to 65 to be the amount they need to equal 65 dollars
{(12-4) + (15-8)}x = 65
There are a few ways to go about doing this, but the easiest is portably to break it up into three shapes: two identical triangles, and a rectangle. The area of one triangle is:
1/2 (10x8) = 40, so the area of two triangles is 80.
The area of the square is 20 x 8, which is 160.
The total area is the sum of the two:
80 + 160 = 240, and this is your total area.
