Answer: x = 35

Final answer: 40, 105, 35.  

Answer: x = 35

So, it would be  40, 3(35), and 35.

Final answer: 40, 105, 35.  

First, we know that sum of angle measure 180.

So, algebraically, we can put out this equation.

40 + 3x + x = 180

Now we solve

Step-by-step explanation:

Given: 40+ 3x + x = 180

The whole goal is to isolate x. Remember DCMAM: Distribute, combine, move variable to one side to another, add/subtract, divide/multiply

There is no distribution, so move on.

We do have to combine 3x with x

40 + 4x = 180.

Now move 40 to the right side.

40 + 4x = 180

-40            -40

4x =  140

Now divide 140 by four

4x/4 = 140/4

x = 35

So, it would be  40, 3(35), and 35.

Final answer: 40, 105, 35.

Hope this helps.

Answer:

X=140/3

Step-by-step explanation:

180-40=140, 140 divided by 3 is 140/3, so 40+3x140/3=180

Alexis is making a cake and needs 4/5 cups of brown sugar for every 3/4 pounds of flour. How much brown sugar will be needed for
malfutka [58]

Answer:

16/15

Step-by-step explanation:

Ratio: 3/4 : 4/5

Whole number ratio: 15 : 16

You need to divide both sides by 15 so you can turn 15 to 1

Divide both sides of the ratio by 15: 1 : 16/15

So, for 1 pound of flour, you need 16/15 pounds of brown sugar for a cake.
