Answer:

x=7 and y=12.

Step-by-step explanation:

If two lines intersect each other then vertical opposite angles are equal.

13x-26=7x+16

13x-7x=26+16

6x=42

Divide both sides by 6.

x=7

The value of x is 7.

(7x+16)^\circ=(7\cdot 7+16)^\circ=(49+16)^\circ=65^\circ

Same side interior angles are supplementary angles.

(7x+16)^\circ+(9y+7)^\circ=180^\circ

65^\circ+(9y+7)^\circ=180^\circ

(9y+7)^\circ=180^\circ-65^\circ

(9y+7)^\circ=115^\circ

On further simplification we get

9y+7=115

9y=115-7

9y=108

Divide both sides by 9.

y=12

Therefore, the value of y is 12.

we \: can \: tell \: that \\ 1. \:  \: 13x - 26 = 7x + 16 \\ 2. \:  \: 7 x + 16  + 9y + 7  = 180\\ from \: 1. \\ 6x = 42 \: so \: x = 7 \\ from \: 2. \\ y = 12

Sunny_sXe [5.5K]

Answer:

25% or 30L

Step-by-step explanation:

100% is 120L, we know 75% is acid, we need the other 25% to make the 100%. 25% of 120 is 30, so 30 liters is pure acid

Solve for X, will give you brainliest and a like
grigory [225]

Answer

Step-by-step explanation:

One solution  :

             x = -1/3 = -0.333

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

               -5*(3*x+1)+4*x-(10*x+2)=0

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 ((0 -  5 • (3x + 1)) +  4x) -  (10x + 2)  = 0

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  -21x - 7  =   -7 • (3x + 1)

Equation at the end of step  3  :

 -7 • (3x + 1)  = 0

Step  4  :

Equations which are never true :

4.1      Solve :    -7   =  0
