9(m-3)+3m=7m+43 what is the answer

Mathematics

Harlamova29_29 [7]3 years ago
5 0

Answer:

9(m - 3) + 3m = 7m + 43

=>9m - 27 + 3m = 7m + 43

=> 12m - 27 - 7m = 43

=> 5m - 27 = 43

=> 5m = 70

=> m = 70/5 = 14

Answer:

m=14

Step-by-step explanation:

start with your parenthesis and multiply 9 to m-3 which makes that 9m-27+3m=7m+43

add your m together making that 12m-27=7m+43

add 27 to both sides equalling 12m=7m+70

subtract 7m from both sides resulting in 5m=70

divide both sides by 5 equalling m=14

Lynne needs to borrow $9500 for cosmetic surgery she obtains a loan from her grandmother for 24 months at a simple interest rate
Andreas93 [3]

Answer:

$11267

Step-by-step explanation:

Loan Future value = amount borrowed + interest

Amount borrowed = 9500

Interest = Principal * Rate * Time/100

Interest = 9500*9.3 * 2/100

Interest = 95*9.3 * 2

Interest = $1767

Loan Future amount = 9500 + 1767

Loan Future amount = $11267

Line PQ is located in the coordinate plane with point P at(-2,-2)
zavuch27 [327]

Answer:

The coordinates of point S are (5, 9) will make line PQ // line RS ⇒ A

Step-by-step explanation:

<em>Parallel lines have  the same slopes</em>

The slope of a line = Δy/Δx, where

  • Δ y is the change of y
  • Δ x the change of x

Let us first find the slope of the line PQ.

∵ P = (-2, -2) and Q = (0, 7)

∴ Δx = 0 - (-2) = 0 + 2 = 2

∴ Δy = 7 - (-2) = 7 + 2 = 9

∴ The slope of PQ = 9/2

∵ Line PQ // line RS

∴ The slope of line PQ = the slope of line RS

∴ The slope of line RS =9/2

∵ Point R = (3, 0) and point S = (x, y)

∵ The slope of line RS = 9/2

∵ The slope = Δy/Δx

∴ Δy/Δx = 9/2

→ That means Δy = 9 and Δx = 2

∵ Δy = y - 0

∵ Δy = 9

∴ 9 = y

∵ Δx = x - 3

∵ Δx = 2

∴ 2 = x - 3

→ Add 3 to both sides

∴ 2 + 3 = x - 3 + 3

∴ 5 = x

∴ The coordinates of point S are (5, 9) will make line PQ // line RS
