. What is the value of r? 0.2(6r − 5) = 8 A. 3.2
B. 7.5
C. 10.8
D 12.4

Answers

Answer 1
Answer: 0.2(6r - 5) = 8 
1.2r - 1 = 8  ( by distributing 0.2 )
1.2r = 8 + 1( by adding 1 )
1.2r = 9 ( dividing 1.2 on both side )
r = 7.5 Ans
Answer 2
Answer:

Answer:

7.5

Step-by-step explanation:

0.2(6r-5)                 =8              Distribute.

0.2(6r)-0.2 (5)         =8              Simplify.

1.2r−1                       =8              Add 1 to each side.

1.2r                          =9              Divide each side by 1.2.

1.2r/1.2                     =9/1.2        Simplify.

r                               =7.5

Hope this helps!

Is 100 inches greater than 3yd 1 ft?

Answers

(3*36 inches) + 12 inches = 120 inches. So no, 100 inches is not greater than 3 yards and a foot. 
1 yard = 36 inches

3 * 36 = 108

1 foot = 12 inches

108 + 12 = 120

So 3 yards and 1 foot is equal to 120 inches.

120 is greater than 100 so 3 yards and 1 foot is greater than 100 inches.

The slope of a line is 0 and the y-intercept is 6 what is the equation of the line written in slope-intercept form

Answers

Answer:

The slope-intercept form of the the line is y=6.

Step-by-step explanation:

The slope intercept form of a line is

y=mx+b

where, m is slope and b is y-intercept.

It is given that the slope of a line is 0 and the y-intercept is 6.

Substitute m=0 and b=6 in the above equation.

y=(0)x+6

y=0+6

y=6

Therefore the slope-intercept form of the the line is y=6.
y = 6. Since there is no slope, if you plug 0 into y = mx + b where m = slope, then you get y = (0)x +b, which leads to y = b. Since b = y-intercept, b = 6. Therefore your equation is y = 6
