Answer: x=t/r+s/r
How to:<u> Isolate the variable by dividing each side by factors that don't contain the variable.</u>
Have a great day and stay safe !
Step-by-step explanation:
There are 84% out of 225. First find 10%. To do that divide the number by 10, so 225 ÷ 10 = 22.5 Next, do 22.5 x 8. Then you have 80%. Now, all that is need ed is the 4%. To get that, divide 225 by 100. Multiply the answer by 4 to get the 4%. Add the 80% and the 4% to get your answer. I really hope this helps. answers
Also, since I am just helping, I am un able to give you straight answers. I hope this also helps with work in the future.
Answer:
![5A + 4P = 10](https://tex.z-dn.net/?f=5A%20%2B%204P%20%3D%2010)
![5A + 5P = 11](https://tex.z-dn.net/?f=5A%20%2B%205P%20%3D%2011)
1 apple costs $1.2
1 pear costs $1
Step-by-step explanation:
Represent Apples with A and Pears with P
For the person in my front, the expression is:
![5A + 4P = 10](https://tex.z-dn.net/?f=5A%20%2B%204P%20%3D%2010)
For me, the expression is
![5A + 5P = 11](https://tex.z-dn.net/?f=5A%20%2B%205P%20%3D%2011)
Hence, the system of equation is:
![5A + 4P = 10](https://tex.z-dn.net/?f=5A%20%2B%204P%20%3D%2010)
![5A + 5P = 11](https://tex.z-dn.net/?f=5A%20%2B%205P%20%3D%2011)
Solving for the values of A and P.
Substract equation (2) from (1)
![5A - 5A + 4P - 5P = 10 - 11](https://tex.z-dn.net/?f=5A%20-%205A%20%2B%204P%20-%205P%20%3D%2010%20-%2011)
![-P = -1](https://tex.z-dn.net/?f=-P%20%3D%20-1)
![P = 1](https://tex.z-dn.net/?f=P%20%3D%201)
<em>Hence, 1 pear costs $1</em>
Substitute 1 for P in ![5A + 4P = 10](https://tex.z-dn.net/?f=5A%20%2B%204P%20%3D%2010)
![5A + 4 * 1 = 10](https://tex.z-dn.net/?f=5A%20%2B%204%20%2A%201%20%3D%2010)
![5A + 4 = 10](https://tex.z-dn.net/?f=5A%20%2B%204%20%3D%2010)
![5A = 10 - 4](https://tex.z-dn.net/?f=5A%20%3D%2010%20-%204)
![5A = 6](https://tex.z-dn.net/?f=5A%20%3D%206)
![A = \frac{6}{5}](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B6%7D%7B5%7D)
![A = \$1.2](https://tex.z-dn.net/?f=A%20%3D%20%5C%241.2)
<em>Hence, 1 apple costs $1.2</em>
Answer:
15y^2 -1
Step-by-step explanation:
(7y^2+y-7)+(8y^2-y-6)
15y^2-1
Answer:
The answer is C
Step-by-step explanation:
Think of p.e.m.d.a.s you do parenthesis first so
1. 4(2x-6)
2. 4*2x= 8x and 4*-6= -24
3. 8x-24 is your answer then you check the other side and oh wow its 8x-24
