Anumber has three digits. the number is less than 140.the number has 7 as a factor. the number is even. the sum of the digits is less than 9. what’s my number?

Step-by-step explanation:

Tough one!

Divisible by 7 and even...meaning it must be divisible by 14.

14 * x where x is less than 10 is the answer :)

That's the only thing I can figure out :)

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
