Answer: The solution for y would be y = -7

Step-by-step explanation:

-Solve:

3y+4y=-49

-First, Combine like terms:

3y+4y=-49

7y=-49

-Then, divide both sides by 7:

7y= -49

\frac{7y}{7} = \frac{-49}{7}

y=-7

So, therefore the result would be y= -7.

RU and JM are diagonals. Given ST= 6, KL = 10, and RU= 12, find JM
AfilCa [17]

Your question is incomplete. The complete question is attached down

Answer:

JM = 20 units

Step-by-step explanation:

∵ Hexagon RSTUVW is similar to hexagon  JKLMNP

∴ The corresponding sides and diagonals have a constant ratio

∴ \frac{RS}{JK}=\frac{ST}{KL}=\frac{TU}{LM}=\frac{UV}{MN}=\frac{VW}{NP}=\frac{RW}{JP}=\frac{RU}{JM}

∵ ST = 6 units

∵ KL = 10

∴ \frac{ST}{KL}=\frac{6}{10}

- Simplify it by dividing up and down by 2

∴ \frac{ST}{KL}=\frac{3}{5}

∵ \frac{ST}{KL}=\frac{UR}{JM}

∵ RU = 12 units

∴  \frac{3}{5}=\frac{12}{JM}

- By using cross multiplication

∴ JM × 3 = 5 × 12

∴ 3 JM = 60

- Divide both sides by 3

∴ JM = 20 units

Answer:

Mr. Miller's farm is 295 acres, and Mr. Newton's farm is 230 acres.

Step-by-step explanation:

From the problem we can make the following equations.....

Let "N" be the area of Mr. Newton's farm and let "M" be the area of Miller's farm. Then.....

N + M = 525

N + 65 = M

Now substitute and get....

N + M = 525

N + N + 65 = 525

2N = 460

N = 230⇒

⇒N + 65 = M

230 + 65 = 295

What is the slope of the line that passes through the points shown in the table?
bonufazy [111]
The slope formula is y2-y1/x2-x1, this is considered rise over run. Simply subtract the y2 variable from the y1 variable, 1-(-1) =2 and then subtract the x2 variable from the x1 variable, 2-1 = 1. From there, ride (y) is on top and run(x) is on the bottom. Divide 2/1 which equal 2. The slope of this line is 2.
Hope this helped :)
