It is b because you round to the nearest 100 and I got it right on the quiz
Answer:
x = 1
y = -3/2
Step-by-step explanation:
Step 1: Arrange the equations with like terms in column.
Step 2: You want 1 set of coefficients that are opposites. This problem already has opposites: -2y and +2y.
Step 3: Solve for x.
4x-2y=7
3x+2y=0
--------------
7x = 7
x = 1
Step 4: Substitute the value of x and solve for y.
4(1)-2y=7
4-2y=7
-2y=7-4
-2y=3
y=-3/2
Answer:
3
Step-by-step explanation:
25+25= 50 spent on the kids, leaving 150 to spend on the adults, 45 can go into 150 3 times.
hope this helps!!!
- Using
substitution
means you are going to solve one equation for one variable and substitute with
its value in the other equation in order to get also an equation with one
variable.
187.69 because 3003.04 divided by 16 is 187.69
