Answer:
4y + 5x + 13
Step-by-step explanation:
4y + 3(y + 1) + 2(x+5)
Distribute
4y + 3y + (3 x 1) + 2x + (2 x 5)
4y + 3y + 3 + 2x + 10
Combine like terms
4y + 5x + 13
Answer:
It has no solution since it is a simultaneously equation. And when you solve to find x and y it gives 0
Answer:
see below
Step-by-step explanation:
In the system of equations, x represents the, price to wash a car and y represents the price to wash an SUV.
If the system of equations is graphed in a coordinate plane, the coordinates (x, y) of the intersection of the two lines are the price of the car wash (x) and the price of the SUV wash (y)______.
x=12 and y = 18
x+y = 12+18 = 30
The total cost of 1 car and 1 SUV is $_30____.
5x+4y = 5(12)+4(18) = 60+ 72 =132
The total earnings for hour 3 are $_132_____.
Answer:
6.1° and 83.9°
Step-by-step explanation:
Complementary angles sum 90°
a+b = 90°
a = b - 77.8
then:
(b - 77.8) + b = 90
2b - 77.8 = 90
2b = 90 + 77.8
2b = 167.8
b = 167.8/2
b = 83.9°
a = b - 77.8
a = 83.9 - 77.8
a = 6.1°
Answer:
30 mins i think its jus simple maths unless theres a twist
