Answer:
What the hell AC is not given so you can't find the Perimeter
Step-by-step explanation:
x+10=0
x=-10
AB=x+5
AB=-5
BC=x-2
BC=-12
Area of ABC = 30cm2
<u>Perimeter of ABC = AB+BC+</u><u>AC</u>

Answer:
C. 11
Step-by-step explanation:
Substituting, we have ...
8{80, 19, 11} ?= 88
{640, 152, 88} ?= 88
The value from the set that makes the equation true is x = 11.
_____
<em>Alternate methods of solution (other than substitution)</em>
It can be easier to make use of your knowledge of factoring:
8x = 8·11
x = 11
Or to make use of your knowledge of numbers (place value):
8·10 = 80
so x will not be very different from 10.
To solve for the unit rate, know that the final answer must be out of 1. Or it is the quantity or amount of something per unit of measurement.
For instance in the above question, the unit rate for 32 teams in 4 divisions would be 8 teams per division.
Likewise for the other question it would be 270/15.
Answer:
149.5, 150.5 , 151.5, 152.5
Step-by-step explanation:
n+(n+1)+(n+2)+(n+3)= 604
Combine Like Terms
4n + 6 = 604
Subtract 6
4n = 598
Divide by 4
n=149.5
Check Your Work:
149.5+150.5+151.5+152.5 = 604
Given:
Selling price of a machine = 7000/-
Gross loss = 20%.
To find:
The cost and gross loss.
Solution:
Let x be the cost of machine.
According to the question,
Divide both sides by 0.8.
So, the cost of the machine is 8750/-.
Now,
Therefore, the gross loss is 1750/-.
