Help please..??
y= –6x+ 14.
Answer:
Let the number of sodas sold be x and the number of hotdogs sold be y. We can assemble a system of equations from the information given and solve.
x+y=170 (We know that soda + dogs is 170)
x-50=y (We know that dogs is equal to 50 less than sodas)
We can use substitution to solve this system of equations.
x+y=170
Sub in the value of y from the second equation
x+(x-50)=170
2x-50=170
2x=220
x=110
We now know the number of sodas sold was 110. Lets now plug this value into the equation to solve for y.
x+y=170
110+y=170
y=60
So, there were 60 hotdogs sold and 110 sodas sold.
The first operation, in order to solve the following situation, is 24 - 4 it gives the rest cars which need to divide equally.
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
Number of cars Stephen had = 24
He gave 4 cars so left will be 24 - 4 = 20
So 20 needs to divide among his 4 friends so the first thing we do is the subtraction of 24 minus 4.
So the first operation will be 24 - 4 = 20
Hence "The first operation, in order to solve the following situation, is 24 - 4 it gives the rest cars which need to divide equally".
