Answer:
1488 sandwiches in thirty minutes
Step-by-step explanation:
Answer:
1. y=3x-1
Step-by-step explanation:
y=mx+b
y=output
m=slope
x=input
b=y-intercept
Step-by-step explanation:
Multiply second equation by -1
-1 × (3x + 2y) = 3
-3x -3y = -3 now add this to the first equation
7x +2y = 17
(-3x-2y)= -3
7x +2y -3x -2y = 17 -3 (2y will eliminate -2y)
4x = 14
x = 7/2 now by using this information we found we can calculate the value for y
if 3x + 2y = 3 (replace x by 7/2)
3 ×(7/2)+2y = 3 ➡ 21/3 + 2y = 3 ➡ 2y = 3 - 21/3 ➡ 2ty = 15/2 ➡ y = 15/4
Answer:
They can all be divided by 3
If the equation is 19-5=3z-11 then the value of z is 15/3.
Given an equation in terms of z is 19-5=3z-11.
We are required to find the value of variable z which exist in equation.
Equation is like a relationship between two or more variables expressed in equal to form. Equations of two or more variables look like ax+by=c. It may be linear equation, quadratic equation,cubic equation,or many more depending on power of the variable.
The value of z can be find as under:
19-5=3z-11
4=3z-11
3z=4+11
3z=15
z=15/3
Hence if the equation is 19-5=3z-11 then the value of variable z is 15/3.
