<span>Simplifying 4x + -1y = 10 Solving 4x + -1y = 10 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add 'y' to each side of the equation. 4x + -1y + y = 10 + y Combine like terms: -1y + y = 0 4x + 0 = 10 + y 4x = 10 + y Divide each side by '4'. x = 2.5 + 0.25y Simplifying x = 2.5 + 0.25y</span>

A construction company can remove 3/3/4 metric tons of dirt from a construction site in 1/1/8 hours what is the unit rate in met
kotykmax [81]

Answer:

3 1/3 metric tons per hour

Step-by-step explanation:

To find the unit rate, divide 3 3/4 metric tons by 1 1/8 hours (notice that the correct format is 3 3/4, not 3/3/4).

 3 3/4 metric tons       3.75 metric tons

---------------------------- = --------------------------

        1 1/8 hours                1.125 hours

It's easier to deal with decimal fractions here than with proper fractions.

The unit rate then comes out to be 3.75/1.125 metric tons per hour, or

3.33333 metric tons per hour, or   3 1/3 metric tons per hour

4x-6&gt;22 explain or prove if 5 or 8 is a solution to the inequality
babunello [35]

Answer:

8

Step-by-step explanation:

4(5) - 6 = 14

14 is not larger than 22, so 5 is not the solution.

4(8) - 6 = 26

26 is larger than 22, so 8 is the solution

The midpoint of the line segment from P1 to P2 is (-6,5). If P1=(-9,7), what is P2?
PolarNik [594]

Let point O be the midpoint of a segment P₁P₂. Then point O has coordinates (-6,5). You also know coordinates (-9,7) of point P₁.

Use formula for midpoint's coordinates:

x_O=\dfrac{x_{P_1}+x_{P_2}}{2} \text{  and  } y_O=\dfrac{y_{P_1}+y_{P_2}}{2}.

Substituting known coordinates, you get:

-6=\dfrac{-9+x_{P_2}}{2} \text{  and  } 5=\dfrac{7+y_{P_2}}{2}.

Thus,

x_{P_2}=-6\cdot 2+9=-12+9=-3,\\ \\y_{P_2}=5\cdot 2-7=10-7=3.

Answer: P_2(-3,3).
