3/4 w -1/2 w - 4 = 12

1 answer:

5 0

The answer is 64 because you add 4 to both sides then you get 3/4w-1/2w=16 then you find like terms between 3/4w and 1/2w and it's 4 so you change 1/2 to 2/4 and then subtract 2/4w from 3/4w and you get 1/4w and that would make your equation 1/4w=16 then you divided by 1/4 which is multiplying by 4 and you get W=64

The points (8,0) and (-8,c) fall on a line with a slope of 1/8. What is the value of c?<br> c=

Anna007 [38]

Answer:

c = - 2

Step-by-step explanation:

calculate the slope m using the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (8, 0) and (x₂, y₂ ) = (- 8, c)

m = $\frac{c-0}{-8-8}$ = $\frac{c}{-16}$ = $\frac{1}{8}$

cross- multiplying gives

8c = - 16 ( divide both sides by 2 )

c = - 2

In a list of 100 numbers , the fraction of numbers greater than 15 is (19/25) and the fraction of numbers less than 15 is (7/50)

Bingel [31]

19/25 * 100 = 1900/25 = 76 ....numbers greater then 15
7/50 * 100 = 700/50 = 14....numbers less then 15

100 - (76 + 14) = 100 - 90 = 10 <== numbers equal to 15
