What’s the answer for 6x+7-4x=8+7x-26

Answers

Answer 1
Answer:

Answer:

x=7

Step-by-step explanation:

Add common variables.

(6x-4x)+7= 8+7x-26

2x+7= 8+7x-26

Subtract the least variable to both sides.

2x+7= 8+7x-26

-2x          -2x

Now, simplify the equation.

7= (8-26)+5x

7= -18+5x

Add 18 to both sides.

7= -18+5x

+18 +18

Divide both sides by 5 to isolate the variable.

35= 5x

5     5

x=7

Which is the greatest of these rational numbers?19/25, 0.33, 0.680, 5/20

A) 0.33
B) 0.680
C) 19/25
D) 5/20

Answers

Answer:

19/25

Step-by-step explanation:

Convert the two fractions into decimals by dividing the numerator by the denominator. 19/25 = 0.76 and 5/20 = 0.25

Now you have: 0.76, 0,680, 0.33 and 0.25.

0.76 is the greatest rational number because it is closest to 1.0, making 19/25 the correct answer.

Find an equation of a line that pass through (4,3) and parallel to y=-4x+1

Answers

Answer:

y = -4x + 19

Step-by-step explanation:

The line parallel to y = -4x + 1 would have the same slope of -4. The coefficient of x will be -4. We can put this into the equation y = -4x + a where a is the y-intercept and a ≠ 1. Now solve for a.

y = -4x + a

plug in 4 for x and 3 for y

3 = -4(4) + a

simplify

3 = -16 + a

+16 both sides

19 = a

a = 19

y = -4x + 19
