I’m assuming you want to figure out what x is in the equation so....

6/8=3/4
2/5=16/40
1/8=5/40
8/10=12/15

I hope this helps.

What is the slope of a line parallel to the line with this equation:
Nutka1998 [239]

The slope of two parallel lines are equal.

Let us find slope of given equation.

The general slope intercept form is given by :

y=mx+c

where m is slope

our equation is :

5x-15y=30

Now we have to convert our equation into slope intercept form.

let us try to isolate y on the left side.

taking 5x to the right side we have ,

-15y=-5x+30

dividing both sides by -15,

y=\frac{x}{3} -2

coefficient of x is slope,

so slope is 1/3

slope of line parallel to it is also same that is 1/3 .

Correct option is D.

Them sum of two numbers is 17. One number is 3 less than 2/3 of the numbers. What is the lesser number?
Flauer [41]

Answer:

The smaller number is 5

Step-by-step explanation:

Let the smaller number be x

the other number is (17 -x) (we know they add up to 17)

2/3 of the bigger number is written as 2/3 (17 - x)

The smaller number is 3 less than that. (so subtract 3 to get x)

x= 2/3 (17 -x) - 3 <-- We have an equation, solve for x

Check 2/3 x 12 - 3 = 8 - 3 = 5

Amy,Ruben,and Sam have a total of $71 in their wallet. Sam has 3 times what Reuben has. Reuben has $9 more than Amy. How much do
iogann1982 [59]
Total = amount Amy has(A) + amount Ruben has(R) + amount Sam has(S)
S = 3 * R
R = A + 9

S = 3 * (A+9)
S = 3A + 27

71 = A + (A + 9) + (3A + 27)
71 = 5A + 36
5A = 35
A = $7

R = A + 9
R = 7 + 9
R = $16

S = 3 * R
S = 3 * 16
S = $48

Lemur [1.5K]

Since a and 5 aren't like terms, you would write the expression as \frac{a+5}{b}
