In the last baseball game, there were two 3-run home runs and 4 hits that each scored 2 runs. Write in algebraic expression to m
Aloiza [94]
Let the number of runs made on the home run be x, then for the <span>two 3-run home runs, we have 2x

Let the number of runs made in each hit be y, then for the 4 hits that each scored 2 runs, we have 4y.

Thus the algebraic expression to model the total score is 2x + 4y.

Because, there are 3 runs per home run, then x = 3 and because there are 2 runs per hit, then y = 2.

Therefore, the total score is given by 2(3) + 4(2) = 6 + 8 = 14.

GEOMETRY PLEASE HELP ME
castortr0y [4]
I'll go by boxes (top statement box is #1, top reason box is #2, etc.)

If you don't have enough boxes, you can omit (remove) the first 2 I wrote, which is the given

1. 8y = 9x - 14; y = 5
2. Given

3. 8(5) = 9x - 14
4. Substitution

5. 40 = 9x - 14
6. Simplification (or multiplication)

7. 54 = 9x
8. Additive property of equality

9. 6 = x
10. Division property of equality

11. x = 6
12. Symmetrical property of equality


Hope this helps (:

Find the slope line (-2 -1) and (-4 -7)
Alenkinab [10]

Answer:

m=3

Step-by-step explanation:

Slope formula

m=\frac{y_2-y_1}{x_2-x_1}

Here

(x_1, y_1) = (-2, -1) \ \ and \ \ (x_2, y_2) = (-4, -7)

Slope can be calculated as

m=\frac{-7-(-1)}{-4-(-2)}

m= \frac{-6}{-2} \\m=3
