Answer:
9.2 bookcases
Step-by-step explanation:
Let X be the number of bookcases repainted.
-Given the available paint is 4 3/5 gallons and that each bookcase consume 1/2 gallon, we equate and solve for X:
Hence, the number of bookcases repaind is 9.2
Answer/Step-by-step explanation:
Problem 1:
Reference angle = 36°
Opposite = x
Adjacent = 7
Thus, apply trigonometric ratio as follows:
tan 36 = x/7
Multiply both sides by 7
7 × tan 36 = x
x = 5.09 (nearest hundredth)
Problem 2:
Reference angle = 63°
Opposite = 12
Hypotenuse = x
Thus, apply trigonometric ratio as follows:
Sin 63 = 12/x
Make x the subject of the formula
x = 12/sin 63
x = 13.47 (nearest hundredth)
13x+4
Combine like terms
If there is a minus sign count it as a negative
Answer:
10
-5
Step-by-step explanation:
5 - -5
Subtracting a negative is like adding
5+5 = 10
-9 - -4
-9+4
-5
Function a is a linear equation
