Y=1/2x +5 Y=-3/2x-7 Find x and y

1 answer:

8 0

I'm going to use the substitution method.

If y = - 3/2 - 7, then:

1/2x + 5 = - 3/2x - 7

Combine like terms:

4/2x = - 12. Mutiply both sides by 2/4 to get x = -12 (2/4)

Simplify to get:

x = - 6.

Plug - 6 back in for x in either equation.

Y = 1/2( - 6) + 5 which becomes Y = - 3 + 5.

X = - 6, Y = 2

$\huge\text{Hey there!}$

$\huge\text{The word \bf{product}}\huge\text{ means multiply in}\\\huge\text{mathematics.}$

$\huge\text{The number is unknown so we can label}\\\huge\text{it as: x}$

$\huge\text{Your equation will be setup like this: -2.5x = 60}$

$\text{-2.5x = 60}\\\text{First divide both sides by -2.5}\rightarrow\dfrac{-2.5\text{x}}{-2.5} = \dfrac{60}{-2.5}\\\text{Cancel out:}\dfrac{2.5\text{x}}{2.5}\text{ because it equals 1}\\\\\text{Keep:}\dfrac{60}{-2.5}\text{because it helps us find the unknown number}\\\\\\\boxed{\boxed{\text{Answer: x = -24}}}\checkmark$

Kayla is running for charity. Her dad pledges to give her $0.50 per mile she runs. Her mom pledges to give her a flat donation o

amm1812

Answer:

10 miles

Step-by-step explanation:

Let m represent the number of miles Kayla runs. We want to find m such that ...

0.50m = 5.00

Divide by the coefficient of m:

m = 5.00/0.50 = 10

Kayla has to run 10 miles to get the same donation from both parents.
