Convert percent to decimal by moving the percent sign two places to the left.

12% => 0.12

'Of' in math means multiply: 0.12 * 30 = 3.6

3.6 is the answer.

eric is ten years older than sal & mick is twice sals age their combined age equals 110 how old is sal
Olenka [21]
2x + x  + 10 + x = 110
4x + 10 = 110 (Subtract ten from both sides)
4x = 100 (divide both sides by four)
x = 25

Plug in values to check...

2(25) + 25 + 25 + 10 = 110
50 + 50 + 10 = 110
110 = 110

Mick is 50 years of age.
Sal is 25 years of age.
Eric is 35 years of age.

Which equation represents the line passing through the points (3, 2) and (-9, 6)?
Sliva [168]

Answer:

Step-by-step explanation:

The equation of a linear function in point-slope form is y – y1 = m(x – x1)

The point is A (x1 , y1)

in this exercice : x1 = 3  and  y1 =2

let  A(3,2)    B(-9,6)

the slope is : m =   (YB - YA)/(XB -XA)

(6-2)/(-9-3)  =4/(-12)  = -1/3

the slope is   m = -1/3

The equation is :  y – y1 = m(x – x1)

y-2 =-1/3 ( x-3)

or : 3y-6 = -x+3
