Helppp pleaseee? im soo confused?

Question

4(3=x)=4(x+3)

and 35 is what percent of 50? thank you

and how do you find the slope of 3x + 5y=30

Answer 1

You got me confused too. But to find the percent of a number you multiply the two (30 and 50) and divide by 100. So I think 35 percent of 50 would be17.5%

Answer 2

On the percentage question, think 35 = X% x 50

Divide both sides by 50 and you get 35/50 = x%

35/50 = .7 = 7-%

Answer 3

1)da 1st 1's not clear

2)70%

3) i believe ur slope is -3/5                

y=mx+b

3x+5y=30

-3x      -3x

5y=30-3x

5y/5=30-3x/5

y=6-3x/5

which is da same as y=-3/5x+6

ur slope is -3/5

Answer 4

4(3+x)=4(x+3)

solve for x

distributive property

12+4x=4x+12

combine like terms

o=o

your answer is infinite solutions

35/50=x/100

cross multiply

3500=50x

solve for x

70%is your answer

3x+5y=30

make a T table

when x is 0, y is 6

when y is 0, x is 10

so your two points are

(0,6) and (10,0)

now you do y1-y2/x1-x2

6-0/0-10

6/-10

-3/5
