Answer:
x = 1.5
y = 3
Step-by-step explanation:
to solve this system of equation using the substitution methods we say let
2x+3y=12................................... equation 1
y=x+1.5..................................... equation 2
substitute equation 2 into equation 1
2x+3y=12................................... equation 1
2x + 3( x + 1.5) = 12
2x + 3x + 4.5 = 12
5x + 4.5 = 12
collect the like terms
5x = 12 - 4.5
5x = 7.5
divide both sides by the coefficient of x which is 5
5x/5 = 7.5/5
x = 1.5
put x = 1.5 into equation 2
y=x+1.5..................................... equation 2
y = 1.5 + 1.5
y = 3
therefore the value of x = 1.5 and y = 3 respectively.
Answer: 14
Step-by-step explanation:
20% of 60=12
20% of 10=2
12+2=14
He rented the bike for 6 hours. If Cody charges an 18 dollar fee up front you subtract that from the total 48 to get 30. Then once you get down to the what he payed for the time used you divide it by 5 because that’s the hourly fee and get 6 hours
The solution to the given equation is -87/45
<h3>Product of expressions</h3>
Given the following expression that represents the word problem as;
-1/5 * 3 - 12(1/3)^2
Using the PEMDAS rule, the parenthesis and exponent will come first to have;
-1/5 * 3 - 12(1/3)^2 = -1/5 * 3 - 12(1/9)
Then multiplication
-1/5 * 3 - 12(1/9) =. -3/5 - 12/9
Find the difference
-1/5 * 3 - 12(1/9) = -27-60/45
-1/5 * 3 - 12(1/9) = -87/45
Hence the solution to the given equation is -87/45
