I think the answer is an auction!
First you solve 2y-3y=9.

Now that you have y, then you substitute y into x-2y=3 to find X

Your solution is (-15, -9)
Answer:
27 13/60
Step-by-step explanation:
What you have tried to do is not an impossible way to do it. What you could do is set your fractions and whole numbers like this.
( 7 + 1/10) * (3 + 5/6) I don't know if you know what FOIL is, but that is the way to proceed.
- First: (meaning the first in each factor ). 3 * 7 = 21
- Outside: (meaning the two terms near outside the brackets) 7 * 5/6 = 5 5/6
- Inside: The two terms closest to the * sign 1 / 10 *3 = 3/10
- Last: The two end terms (1/10 * 5/6 = 5/60 5/60
Now you can add. 21 + 5 is the whole number amount = 26
Add the fractions
- 5/6 + 3/10 + 5/60 The lowest common multiple is 60
- 50/60 + 18/60 +5/60 = 73 / 60 = 1 and 13/60
Add that to 26 and you get 27 13/60
Answer:
it would be 75
Step-by-step explanation:
if add 10+ 10+ 30 + 25 its would be 75
Surface area= Area of all the shapes added together
Area of square =s^2
Area of triangle =bh/2
S=12
B=12 B is s
H=8
12^2 =144 square
12×8= 96/2=48 triangle
There are 4 triangles and 1 square
144+48+48+48+48=336 Answer is f hope that helps
