When solving equations like these, our number one goal is to get x to be alone.

So given the equation lets go through it step by step.

3x - 5 = 10 + 7x  (first step is to add 5 to both sides)

    + 5 = + 5    ( Now lets see what we have now)

3x = 15 + 7x ( We need the x to be alone! So lets subtract -7x from both sides.)

-7x =       -7x   ( now what do we have?)

-4x = 15  (okay divide both sides by 4 to isolate the x)

÷4 = ÷4   (now the 4's on the left side cancel out, and we solve on the right side)

x = 3.75

That's your answer :) Good Luck!

There are 2 angle measurements not identified.

Angle ACB and angle ABC.

To find angle ACB you need to know that a straight line is 180 degrees, so if the angle to the right is 131, the angle to the left (Angle ACB) must be 49 degrees.

To find angle ABC, you need to know that the sum of all 3 angles in a triangle equal 180 degrees, so 180 - (49 + 44) = 87 degrees.  Angle ABC is 87 degrees.

Jessie sorted the coins in her bank. She made 7 stacks of 6 dimes and 8 stacks of 5 nickels. She then found 1 dime and 1 nickel.
ANEK [815]
Hello!

So, Jessie made 7 stacks of dimes and 8 stacks of nickels.

Each stack of dimes has 6 dimes.

Each stack of nickels has 5 nickels. Multiply:

6 × 7 = 42

8 × 5 = 40

Then she finds another dime and another nickel.

42 + 1 = 43

40 + 1 = 41

43 + 41 = 84

ANSWER:

Jessie has 43 dimes, 41 nickels, and 84 coins in all.

A painter leans a 20 ft ladder against a building. The base of the ladder is 8 ft from the building. To the nearest foot, how hi
Shalnov [3]

Answer:

Step-by-step explanation:

This is asking what is A

Formula A squared + B squared = C squared

A=x

B=8

C=20

X^2+ 8^2=20^2

8 squared is 64

20 squared is 400

400-64 is 336

X*X=336 find the square root of 336 =18.3

CHECK

18.3*18.3+ 8*8=398.89 which is super close to 400

How much water do you need to add to make each concentration?<br> 1% sugar syrup using 12 g sugar
yulyashka [42]

Answer:

1188 grams of water

Step-by-step explanation:

x is the grams of water

so total is 12+x grams

sugar/total is 12/12+x

and 1% ratio is 12/12+x=1/100

so x would be 1188 grams of water.
