Answer:
336 sq. in or 2.333333333 sq. ft.
Step-by-step explanation:
1 foot = 12 in
7 x 12 = 84 in
A = bh
A = 84 in x 4 in
A = 336 sq. in
1 sq. ft. = 144 sq. in
336 / 144 = 2.33333333 sq. ft.
They are looking for the y intercept. The line of best fit passes the y axis at 1. the y axis is labeled minutes stretching. therefore the answer is
A. <span>1 minute; the number of minutes students stretch when they do not jog</span>
Recall that all three angles in a triangle equals 180.
Knowing this, we just have to add up all the angles and figure out what the value 'x' is.
(x-22 + x-17 + 3x+19) = 180
Simplify:
5x - 20 = 180
Add 20 to both sides:
5x = 200
Divide both sides by 5:
x = 40
Now that we found the value for x, we need to solve for angle A.
Simply input the value of 'x' into angle A's equation:
40 - 22 = 18
Angle A = 18 degrees
Good luck! If you need me to explain anything, just ask :))

3.0 NOT SURE IF ITS CORRECT
first combine like terms so 2n + 7n which is 9n
so 9n + 7 = 13 + 3n + 8n
then combine on other side so 9n + 7 = 13 + 11n
then subtract 7 to 13 so 6
sp 9n + 6 = 11n
then subtract 9 to the other side so 2n
6 = 2n then divide all by 2
n= 3
