Answer:

x = 0

Step-by-step explanation:

-7(5-3x)=-35

Divide by -7

-7/-7(5-3x)=-35/-7

5 -3x = 5

Subtract 5 from each side

5-3x-5 = 5-5

-3x=0

Divide by -3

x=0

Answer: x = 0

Step-by-step explanation: Start by distributing the -7 through the parenthses on the left side of the equation.

-7(5) is -35 and -7(-3x) is 21x.

So we have -35 + 21x = -35.

Next, isolate the x term by adding 35 to both sides.

When we do this, we get 21x = 0.

Now divide both sides by 21 and <em>x = 0</em>.

HURRY PLEASE HELPPPPPPP

elena-s [515]

Answer:

I think the answer is D

if we use this equation to find the slope ( slope= Y2-Y1/X2-X1)

6-3= 3

2-1=1

so then you divide it and you get 3/1 or 3

You bike 11.2 miles in 1.4 hours at a steady rate. What equation represents the proportional relationship between the x hour you

Elis [28]

Answer:

$\frac{x}{y}=8$

Step-by-step explanation:

Let the time for which i bike is = x hours

Let the distance traveled in x hours = y miles

Ratio of distance and time will be = x : y

I travel 11.2 miles in 1.4 hours then the ratio of time and the distance traveled will be 1.4 : 11.2 Or 14 : 112

then the ratio of distance and time will be same in both the cases

So equation will be

$\frac{x}{y}=\frac{14}{112}$

$\frac{x}{y}=8$

Therefore, equation representing the proportional relationship will be

$\frac{x}{y}=8$

What is the value of y in this system of equations?

mote1985 [20]

Answer:

-21

Step-by-step explanation:

-6x + 2y = -18.........(i)

-3x - 2y = 54...........(ii)

add equ.(ii) to equ. (i)

(-6x + [-3x]) + (2y + [-2y]) = -18 + 54

-9x = 36

x = -4

sub x= -4 into equ (i)

-6(-4) +2y = -18

24 + 2y = -18

24 +18 = -2y

42 = -2y

y = -21
