Answer:
27
Step-by-step explanation
Sally = 4 x 3 = 12(left) + 15(spent) = 27
Lucy = 24(spent) + 3(left) = 27 (we dont multiply this part bc Lucy spent 9 more dollars than Sally, 3 x 3 is 9 which equals the difference)
Answer:
2
Step-by-step explanation:
Variable is "a" and the expression is 6-a
The value of x in order for the two slats to be parallel is 6.
The measure of the indicated angle is 42°
What is an angle?
The angle is the measure of how inclined are the two surfaces, or lines with respect to each other.
For the slats to be parallel. both the given angles must be equal
So,
(3x +24)° = 7x°
Solving this expression, we get
7x -3x = 24
4x =24
x = 6°
The measure of the indicated angle is
(3x +24)° = 3x6 +24
(3x +24)° = 18+24
(3x +24)° =42°
and 7x = 7x6 =42°
Thus, the measure of the angle is 42°
