Answer:
2-1/-2--4= 1/2
0-1/0-2=-1/-2
2-0/-1-0=2/-1
-2--1/4-2=-1/2
can i have a Brainliest plz thank you
The answer you are looking for is no solution.
To find this, you first distribute the -5 into the parenthesis (-4r - 6). -5 x -4r = 20r and -5 x -6 = 30.Next, distribute the 5 into the parenthesis (6 - r). 5 x 6 = 30 and 5 x r = 5r.
The equation says 20r + 30 = 5r + 30. Now you solve for r.Subtract 5r from both sides. This leaves the equation to say 15r + 30 = 30. Then subtract 30 from both sides, to get 15r = 0.
At this point, since there is a zero on the opposite side of the variable, you can assume it will be no solution, since multiplying or dividing 0 by anything, is 0. However, I'll finish the problem, to show that it is no solution.
Divide 15 from both sides, leaving r = 0, which is no solution.
I hope this helps!
An integral number is just a whole number. Consecutive means they are neighbouring in the number line(e.g. 2,3,4). Let the smallest number be x:
x + (x+1) + (x+2) = 3x + 3 = 117
3x = 114
x = 38
Hence the numbers are 38, 39, 40
90% = 9,750
9750/90 = 1%
1% = 108.3
100% = 10,833.3
original retail price = $10,833.30
Answer:
The equations


The solution
55 dimes and 25 quarters
Step-by-step explanation:
Given
Let
quarters
dimes


Required
Set up a system of equation to calculate the number of each coin
The total coin of 80 implies that:


A dime = $0.1
A quarter = $0.25
So, the worth of the coin is:


So, the equations are:


Next, solve for x and y
Multiply the second equation by 4
by 4

Subtract from 


Solve for y

We have:




<em>Hence, there are 55 dimes and 25 quarters</em>
