Answer:
length=45 m (2 sides = 90m)
Step-by-step explanation:
5x +3x=144
8x=144
x=18 (each of the 8 parts of 144 measure 18m)
5(18) + 3(18)=144
90 +54=144
90/2=45 (1 length side)
54/2=27 (1 width side)
The rectangle= 45+45 +27+27 = 144
Answer:
x = 30
Step-by-step explanation:
by solving ;
- 18 / x = 6 / 10
- 1 / x = 6 / ( 18 × 10 )
- 1 / x = 6 / 180
- 1 / x = 1 / 30
- x = 30
Answer:
a³-b³= (a-b)(a²+ab+ b²)
Step-by-step explanation:
The values have being matched to the variables that they represent here:
- x-variable: the number of hours Sam works at the airport
- y variable: the amount in dollars that Sam has after paying back Daniel
- 12: amount in dollars that Sam earns per hour.
- 40: the amount in dollars Sam owes Daniel
<h3>How to solve for the equation.</h3>
The equation of this form y = 12x-40
The variable y has been said to be the amount sam has after Daniel has been paid.
X is the amount that has to be multiplied by what he earns in dollars by the hour.
40 dollars is the amount that he owes which is going to be subtracted from what he earns by the hour.
