Can you show the mentioned diagram?
Answer:
C. 13
Step-by-step explanation:
The two given equations are:
<span>-14=-20y-7x and 10y+4=2x
In order to find x and y, we can do it by substitution or by elimination.
By Elimination.
</span><span>Multiply 10y+4=2x by 2
= 20y + 8 = 4x
Then add it to the second equation
</span>-20y - 7x = -14
20y - 4x = -8
---------------------
-11x = -22
x = 2
Then get y,
10y+4=2x
10y = 2x - 4
10y = 2(2) - 4
y = 0.
So the answer is x = 2, y = 0
Ur answer is
12.5
heres what helps me when im stuck hope it helps u =^-^=
pemdas steps
parentheses 1st
exponent 2nd
multiply 3rd
divide 4th
add 5th
subtract 6th
Hello, please consider the following.
For the second we will need to put on the same denominator.
Thank you.
