4/5 w+13=25 please show work

w=15

Step-by-step explanation:

4/5*w+13-(25)=0

STEP 1

4

Simplify —

5

Equation at the end of step1

4

((— • w) + 13) - 25 = 0

2.1 Adding a whole to a fraction

Rewrite the whole as a fraction using 5 as the denominator :

13 13 • 5

13 = —— = ——————

1 5

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

4w + 13 • 5 4w + 65

——————————— = ———————

5 5

Equation at the end of step2

(4w + 65)

————————— - 25 = 0

STEP 3

Rewriting the whole as an Equivalent Fraction :

3.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 5 as the denominator :

25 25 • 5

25 = —— = ——————

1 5

Adding fractions that have a common denominator :

3.2 Adding up the two equivalent fractions

(4w+65) - (25 • 5) 4w - 60

—————————————————— = ———————

5 5

STEP4

Pulling out like terms :

4.1 Pull out like factors :

4w - 60 = 4 • (w - 15)

Equation at the end of step

4 • (w - 15)

———————————— = 0

STEP 5

When a fraction equals zero :

5.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

4•(w-15)

———————— • 5 = 0 • 5

5

Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

4 • (w-15) = 0

Equations which are never true:

5.2 Solve : 4 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

5.3 Solve : w-15 = 0

Add 15 to both sides of the equation :

w = 15

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
