Answer:
162, 163, and 164.
Step-by-step explanation:
Here we will use algebra to find three consecutive integers whose sum is 489. We start by assigning X to the first integer. Since they are consecutive, it means that the 2nd number will be X + 1 and the 3rd number will be X + 2 and they should all add up to 489. Therefore, you can write the equation as follows:
(X) + (X + 1) + (X + 2) = 489
To solve for X, you first add the integers together and the X variables together. Then you subtract three from each side, followed by dividing by 3 on each side. Here is the work to show our math:
X + X + 1 + X + 2 = 489
3X + 3 = 489
3X + 3 - 3 = 489 - 3
3X = 486
3X/3 = 486/3
X = 162
Which means that the first number is 162, the second number is 162 + 1 and the third number is 162 + 2. Therefore, three consecutive integers that add up to 489 are 162, 163, and 164.
162 + 163 + 164 = 489
We know our answer is correct because 162 + 163 + 164 equals 489 as displayed above.
Answer:
c. $89.73
Step-by-step explanation:
Given
The restaurant bill = $73.25
If you are taxed 7 1/2% or 7.5%
Decide to tip your server 15%
We have to find a new tax
To get the new tax, we will to multiply the bill by the tax you are taxed
73.25*0.075=5.49 tax
To get the total, we will have to multiply the bill by the tip after we have add one(1 + 15/100= 1.15) and then add it by the new tax
73.25*1.15+5.49=$ 89.73
Answer:
(1,-5) (6,-5) (1,-7)
Step-by-step explanation:
For the bottom left of the triangle, the coordinate would be = (1,-5)
The bottom right, = (6,-5)
Top left = (1,-7)
