Answer:
-5(3x+4) = 25
-15x-20=25
-15x=25+20
-15x=45
>then divide both side by -15
Therefore: X=-3
4(x+2)-3(2x-4)=10
4x+8-6x+12=10
-2x+20=10
-2x=-10
> divide both sides by -2
Therefore: x= 5
Answer:
108° and 72°
Step-by-step explanation:
let one angle be x then the other angle is
x
the sum of the 2 angles = 180°, hence
x +
x = 180 ( combining the left side )
x = 180
multiply both sides by 3 then divide both sides by 5
5x = 540 ⇒ x = 108
the 2 angles are x = 108° and
x = 72°
Answer:
28.278ft^2
Step-by-step explanation:
Given data
Diameter of painting= 6ft
Radius= 3ft
Let us find the area of the painting
Area= πr^2
Substitute
Area= 3.142*3^2
Area= 3.142*9
Area= 28.278ft^2
Answer:
D
Step-by-step explanation:
The quotient is the result of dividing one number by another.

is how you would represent the quotient of 10 and 1/7.
The opposite of division is multiplication, and those we can rearrange that and get:

or in other words, "what number divided by 7 is 10"
The answer becomes clearer, 70 is that number.
D represents this idea.
