With this 1 question it's 20 points.

answer:

5x = 10

yields

x=2 y=0

step-by-step explanation:

2x+y=4 3x-y=6

we want to add these equations

2x+y=4

3x-y=6

5x = 10

if we divide by 5 on each side

5x/5 = 10/5

x =2

now we can find y

2x+y =4

2(2) +y = 4

4+y =4

subtract 4   from each side

4-4 +y = 4-4

y =0

answer:

60 = 2^2·3·5

104/2 = 2·6 + 2·5 + 6·5

the side length are 2, 5 and 6 meters.

answer: i'm going in

step-by-step explanation:

answer:

option a. 4, 4.5, 5, 5.5

step-by-step explanation:

left point: a=x=4

right point: b=x=6

range: r=b-a→r=6-4→r=2

width of each of the four equal intervals: w=2/4→w=0.5

the first left endpoint is x1=a→x1=4

the second left endpoint is x2=x1+w→x2=4+0.5→x2=4.5

the third left endpoint is x3=x2+w→x3=4.5+0.5→x3=5

the fourth left endpoint is x4=x3+w→x4=5+0.5→x4=5.5

then, the list is: x1, x2, x3, x4 = 4, 4.5, 5, 5.5
