the soccer team collected $800 at a car wash fundraiser. They charged $5.00 for small vehicles and $10.00 for larger vehicles. The amount collected can be modeled by the equation 5x + 10y = 800, where x represents the number of small vehicles and y represents the number of larger vehicles. If the number of larger vehicles washed was 50, how many small vehicles were washed in total?
Answers
replace y by 50: 5x+10(50) = 800
5x+500 = 800
5x = 800-500
5x = 300
x = 300/5
x = 60
60 small vehicles were washed in total.
proof: 5x+10y = 800
replace x=60 and y=50
so; 5(60) +10(50) =800
300 + 500 = 800
800 = 800
Answer:
60 in total
Step-by-step explanation:
proof: 5x+10y = 800
replace x=60 and y=50
so; 5(60) +10(50) =800
300 + 500 = 800
800 = 800

Answer:
the value of j in the given expression is: 16
Step-by-step explanation:
we are given the expression as:
so on squaring both side we have .
Hence the value of j is 16.
The equation is:
√j + √j + 14 = 3√j + 10
2√j + 14 = 3√j + 10
14 - 10 = 3√j - 2√1
4 = √j
Now, we will square both sides of the equation:
4² = (√j)²
16 = j.
Therefore, j is 16.

The following things should be considered:
- Since there are 12 parts.
- Each one should we 30 degrees i.e.
- Now 8 - 3 = 5
- So, the angle should be
= 150 degrees.
Therefore we can conclude that The number of degrees does it move is 150 degrees.

Write steps and inverse
Answers
Answer:
y=2/(x−7)
Step-by-step explanation:
To find the inverse function, swap x and y, and solve the resulting equation for x. If the initial function is not one-to-one, then there will be more than one inverse. So, swap the variables: x=7+(2/y) for y. y=2/(x-7).
