Answer:
The number is 19
Step-by-step explanation:
7 less than a number = x - 7
2x - x - 7 = 12
Subtract x from 2x
x - 7 = 12
Add 7 to both sides of the equation
x = 19
The number is 19

Answer:
15/2r - 40; Distributive Property
Step-by-step explanation:
You can use the Distributive Property to multiply the 5 across the expression in the parentheses.
5(3/2r - 8)
5 × 3/2r = 15/2r
5 × -8 = -40
Combine.
15/2r - 40
Hope this helps!
Answer:
160
Step-by-step explanation:
60% of a + 24 = 3a/4
=> 60a/100 + 24 = 3a/4
=> 3a/5 + 24 = 3a/4
=> 3a / 4 - 3a/5 = 24
=> ( 15a - 12a) / 20 = 24
=> 3a / 20 = 24
=> a = 24 × 20 / 3
=> a = 8 × 20
=> a = 160

Answer:
Equation of line best fits the scatter plot is y =
Step-by-step explanation:
Let the equation of line be y = mx + c
where m = slope of line and c is the intercept on y -axis
from the graph intercept on y-axis is 108
and the slope of line is given by m = where () and () is the points on line
let, points be (4,96) and (18,36)
on calculating this m = =
Therefore equation of line best fits the scatter plot is y =
