1. Parenthesis:
(15)8 - 4 + 2 + 1
Multiply:
120 - 4 + 2 + 1
Subtract:
116 + 2 + 1
Add:
119, the answer is A.
2. 8 x 15 = 120
120 / 2 = 60
6 x 15 = 90
90 + 60 = 150
The answer is A.
Hope this helps!
Answer:
y=3x- 3/2
Step-by-step explanation:
4.2x−1.4y=2.1
Subtract 4.2x from each side
4.2x-4.2x−1.4y=-4.2x+2.1
-1.4y = -4.2x +2.1
divide each side by -1.4
-1.4y/-1.4y = -4.2x/ -1.4 +2.1/-1.4y
y=3x- 3/2
Answer:
x = 96
y = 66
Step-by-step explanation:
The sum of interior angles of the given shape is 360:
x + y + 123 + 75 = 360
x + y + 198 = 360 subtract 198 from both sides
x + y = 162
The angle with the measure 114 and angle y are supplementary so their sum is 180
y + 114 = 180
y = 66 since x + y = 162 we can use this to find the value of x
x = 162 - 66
x = 96
Answer:
The average rate of change
At t = 1
at t=3
Step-by-step explanation:
<u><em>Step(I)</em></u>:-
The given function h(t) = 3+70t - 16t²
The 
70 - 32 t = 0
⇒ 70 = 32 t
⇒ 
<em>Step(ii</em>):-
The average rate of change in h(t) between t = 1 second and t = 3 second
At t = 1
At t = 3
