Simplify the expression. 6(7n – 5m) + 8m

1 answer:

8 0

6 (7 n - 5 m) + 8 m
6 (7 n - 5 m) = 42 n - 30 m:
42 n - 30 m + 8 m
Grouping like terms, -30 m + 42 n + 8 m = 42 n + (8 m - 30 m):
42 n + (8 m - 30 m)
8 m - 30 m = -22 m:
42 n + -22 m
Factor 2 out of 42 n - 22 m:
Answer: 2 (21 n - 11 m)

Triangle HIJ has vertices H(1, 7) , I(−4, −2) , and J(−3, 5) . Write the coordinate notation for a translation of 3 units right

e-lub [12.9K]

Step-by-step explanation:

(x, y) -> (x+3, y+4)

that is what 3 units to the right (3 units into the outsource x direction) and 4 units up (4 units into the posits y directing) mean.

so, all points go through this translation

(1, 7) -> (4, 11)

(-4, -2) -> (-1, 2)

(-3, 5) -> (0, 9)

Solve for x. 25x=65 x = 1225 x = 125 x = 3 x = 6

masya89 [10]

25x=65

We divide 25 to cancel it out.

65/25=2.6

I would assume 3, because 2.6 is 3 when rounded up.
