Welp lol <3 find the value of x that makes j||k
alukav5142 [94]

Answer: C. 42

Step-by-step explanation:

(3x + 3) is the same angle as 129.

So, you have to equal them to each other.

3x + 3 = 129

Now you solve.

Subtract 3 from each sides.

3x = 126

Divide 3 from each side.

x=42

PLEASE HELP ASAP ALGEBRA 2 QUESTION
Jlenok [28]
Let x represent the gallons of water that is 10% salt.

Let y represent the gallons of water that is 25% salt.

Now, write the system of equations:

x + y = 10

.10x +.25y = 0.20 • 10


1) To make the system easier to solve, multiply all the terms in .10x +.25y = 0.20(10) by 100 to make them integers.

10x + 25y = 20 • 10

10x + 25y = 200   

2) Solve for x.

x + y = 10

x = 10 - y

3) Substitute x with 10 - y in the other equation.

10(10 - y) + 25y = 200

100 - 10y + 25y = 200

Combine like terms.

100 + 15y = 200

Subtract 100 from both sides.

15y = 100  

y = 20/3 or 6 2/3

4) Now that we have the numerical value of y, solve for the value of x by substituting once more.

a) x + y = 10

x + 20/3 = 10 or x + 6 2/3 = 10 (either equation is fine)

x = 10/3 or x = 3 1/3

The manager should combine 3 1/3 (3.33) gallons of 10% salt water and 6 2/3 (6.67) gallons of 25% salt water.

5) Always check the answers to make sure.

a) x + y = 10

3 1/3 + 6 2/3 = 10

9 3/3 = 10

10 = 10

b) .10x +.25y = 0.20 • 10

.10(3 1/3) +.25(6 2/3) = 0.20 • 10

1/3 + 5/3 = 2

6/3 = 2

2 = 2

goldenfox [79]
<span>1.25 = 0.75x + 50
0.75x = 1.25 - 50
0.75x = -48.75
x = -48.75 / 0.75
x = 65</span>
