PEMDAS
parentheses, exponent, multiplication/division, addition/subtraction
first, start with what is inside the parentheses that is solvable.
5(6) - (x-3) = -4(4x+5) + 13
multiply what you can
30 - (x-3) = -16x - 20 + 13
simplify
30 - (x-3) = -16x - 7
subtract 30 on both sides
- (x-3) = -16x - 37
let’s separate -(x-3).
-x - 3 = -16x - 37
add 16x to both sides
15x - 3 = -37
add 3 to both sides
15x = -34
x = -34/15 or -2.2667
Answer:
Average speed in km / h = 2.7 km/h
Step-by-step explanation:
Given:
Total distance = 54,000 m
Total time = 72,000 sec
Find:
Average speed in km / h
Computation:
Average speed = Distance / Time
Average speed = 54,000 / 72,000
Average speed = 0.75 m/s
1 m/s = 3.6 km/h
So,
Average speed in km / h = 0.75 x 3.6
Average speed in km / h = 2.7 km/h
65 I think
So I did 4•5=20 and 9•5=45 and added 20+45 which equals 65
Answer:
32°
Step-by-step explanation:
since m ||n
x=32° ---- because corresponding angles are equal
