36 and 144
Explanation
Two Angles are Supplementary when they add up to 180 degrees
Step 1
Let
x= angle 1
y= angle2
The measure of one angle is four times the measure of the other angle,then
x and y are supplementary angles , then
Step 2
use Equation (1) and (2) to find x and y
replace Equation (1) in Equation (2)
replace the value of y= 36 in equation (1) to find x
Hence, the answer is 36 and 144
Start by solving inside the parentheses. According to PEMDAS you will divide 10 and 2 first. Divide 10 by 2 and you will have: 8 + (5)(4) - (6 + 5) + 44.
Now finish solving inside the parentheses and add 6 and 5.
8 + (5)(4) - (11) + 44, multiply 5 and 4.
8 + 20 - 11 + 44, then solve from left to right.
61 is the answer.
A. The expression for the problem is 10+ 2x (10 dollars a week plus 2 per chore.)
B.10 +2(5) =$20
C. 10(4)+2x=144 // 40+2x=144 //2x=104 // x=52 (she will need to do 52 chores :)
We first get the gradient of the equation of a line by taking the
change in y over change in x
Hence our gradient will be
(6-9.5)/(8-1)=-3.5/7=0.5
Taking an arbitrary point(x,y) and using our gradient we get
and one of the points above we get
(y-6)/(x-8)=0.5
y-6=0.5*(x-8)
y-6=0.5x-4
y=0.5x+2 or y=1/2x+2
which is the line of our equation the answer we are
asked for.

Answer:
1.29 s
Step-by-step explanation:
h = -490t² + 1260t
810 = -490t² + 1260t
490t² - 1260t + 810 = 0
49t² - 126t + 81 = 0
(7t - 9)² = 0
7t - 9 = 0
t = 9/7
t ≈ 1.29
