Answer: 19, 20, and 21
Step-by-step explanation: This problem states that the sum of 3 consecutive integers is 60 and it asks us to find the integers.
Three consecutive integers can be represented as followed.
X ⇒ first integer
X + 1 ⇒ second integer
X + 2 ⇒ third integer
Since the sum of our 3 consecutive integers is 60, we can set up an equation.
X + X + 1 + X + 2 = 60
3x + 3 = 60
-3 -3
3x = 57
÷ 3 ÷ 3
X = 19
X + 1 = 20
X + 2 = 21
Therefore, our three consecutive integers are 19, 20, and 21.
60 = x + x + 1 + x + 2
60 = 3x + 3
-3
57 = 3x
/3
19 = x
The 3 integers are: 19, 20, and 21.
Answer:
Distribute this, : 4(x-3)=9 to get 4x-12=9
Let p represent the computer’s original price.
A. 0.25p = p – 180
B. 0.75p = p + 180
C. 0.25(p – 180) = p
D. 0.75p = p − 180
We are required to find equation which compare the price of computer in both stores.
The equation that represents the expression is 0.75p = p - 180 and the value of the computer's original price is $720
Let
p = the computer’s original price.
Store A = 25% off the original price.
= p - (25% of p)
= p - (25/100 × p)
= p - (0.25 × p)
= p - 0.25p
= 0.75p
Store B = p - 180
The equation:
Store A = store B
0.75p = p - 180
0.75p - p = -180
-0.25p = -180
divide both sides by -0.25
p = -180 / -0.25
p = $720
