Solve the system of equations using the substitution method.

Answers

Answer 1

Answer: Multiply 3x +y =23 by -4

x+4y=4
-12x+(-4y)=-92

Add together

-11x = -88

x = 8

Plug x in to find y.

8 + 4y = 4

Subtract 8 from each sides

4y = -4

Divide by 4

y = -1

So the answer is x =8, y= -1

I hope that helps!

Answers

so we have 60

then we have
central:5
Riversie:24
Maple park:20
west:11
they all add up to sixty

so we find their percentages
percent means part out of 100 wo what you do is
5/60=1/12=0.0833333333/1 then make bottom number 100 so 0.08333/1 times 100/100=8.3/100=8.3%

so the others are
24/60=2/5=0.40/1 times 100/100=40/100=40%
20/60=1/3=0.333333/1 times 100/100= 33.33/100=33.33%
11/60=0.1833/1 times 100/100=18.33/100=18.33%

so now we have

central:8.33%
Riversie:40%
Maple park:33.33%
west:18.33%

so we look at our options
A. riverside=24% FALSE
B. maple park=33.33% TRUE
C.maple park has highest percentage FALSE
D. central is smallest percentage TRUE

answer is B and D
