Try the KISS method. Keep it. Switch. Switch. keep the first number, switch the symbol, then switch the sign of the second number. so it would be 6+2=8

Rico can walk 3 miles in the same amount of time that Donna can walk 2 miles. Rico walks at a rate 2 miles per hour faster than
tatyana61 [14]

Answer:

13

Step-by-step explanation:

Donna's Rate is R

Rico's Rate is R+2

\frac{R}{R+2}=\frac{2}{3}

Cross-Multiply

2(R+2)=32

2R+4=3R

4=R

Donna's Rate is R=4

Rico's Rate is R+2=6

\frac{6(130)}{60} = \frac{130}{10}=13

Need help (pic included)
ValentinkaMS [17]

Answer:

(-4,-2)

x=-4

y=-2

Step-by-step explanation:

-3x-4y=20

3(x-10y=16)=3x-30y=48

The reason I multiplied 3 to the second equation is for when we add the equations together the x will cancel out.

  -3x-4y=20

+  <u>3x-30y=48</u>

  -34y=68

Divide -34 from both sides.

y=-2

To find x you need to plug in -2 for y into one of the equations.

x-10y=16

x-10(-2)=16

Remember a negative times a negative equals a positive.

x+20=16

Subtract 20 from both sides.

x=-4

Hope this helps!

If not, I am sorry.

Use distributive property to create an equivalent expression to 7x + 56
OverLord2011 [107]
You will have to factor this equation. This means you have to find the lowest number that goes into both 7 and 56 (in other terms, gcf(7, 56)). You will put that as the leading coefficient in this factored term. gcf(7,56) = 7 so 7 will be leading coefficient. It will look somewhat like this 7(a + b) (a and b are just random variables representing what will go inside the parentheses). a and b can be determined by dividing each term in this expression by 7. Hence, 
7x + 56 = 7(x + 8).This can obviously also be proven by the distributive property.
