Answer:

1/5

Step-by-step explanation:

In order to solve this, you need to simplify. In this case, we would need to distribute first.

-5x - (-7 - 4x) = -2(3x - 4)

-5x + 7 + 4x = -6x + 8

Combine like terms:

-5x + 7 + 4x = -6x + 8

-5x + 6x + 4x = 8 - 7

-x + 6x = 1

5x = 1

X needs to be by itself, so you would divide by 5 (the coefficient in front x) on both sides. So,

5x = 1

x = 1/5

The teacher collected some snowfall data during one of the snow days last year. Estimate the total snowfall throughout the day.

Sedaia [141]

The total snowfall throughout the day is the expected value of the distribution.

The estimated total snowfall during the day is 30 inches

Start by calculating the average rate of snow collected on that day.

$Rate = \frac{0 + 1.5 + 2.5 + 2.0 +1.0 +0.5}{6}$

This gives

$Rate = \frac{7.5}{6}$

Divide 7.5 by 6

$Rate = 1.25$

There are 24 hours in a day.

So, the total snowfall is:

$Total = Rate \times Hours$

This gives

$Total = 1.25 \times 24$

Multiply

$Total = 30$

Hence, the estimated total snowfall during the day is 30 inches

What is the solution for the system of equations? y=−x+4 y= x−2

MissTica

Answer:

(3, 1 )

Step-by-step explanation:

Given the 2 equations

y = - x + 4 → (1)

y = x - 2 → (2)

Substitute y = x - 2 into (1)

x - 2 = - x + 4 ( add x to both sides )

2x - 2 = 4 ( add 2 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Substitute x = 3 into either of the 2 equations and solve for y

Substituting into (2)

y = 3 - 2 = 1

solution is (3, 1 )
