Answer:
Step-by-step explanation:
there are two ways to solve systems of equations, elimination or substitution, this looks like elimination would work quickly
x= 25 -y
x + y = 25 (eq 1)
5x + y = 10 (eq 2)
subtract 2 from 1
x + y = 25
-(5x + y = 10)
-4x + 0y = 15
-4x = 15
x = - 15/4
now plug in x into either starting equations and solve for y
-15/4 + y = 25
y = 25 + 15/4
y = 100/4 + 15 /4
y = 115 /4
y = 28 3/4
we have solved it :)
It’s 81.27 ... uhhh i’m confused LOL
D. 7/10 of newspapers and a. 1/8 pound
I'm going to say for this one it's going to be 46% Notice that the word percent has the word "cent", meaning a hundred. So "per hundred". We have 46 out of 100 here, so 46/100, and we can simplify to 23/50. Hope this helps.
The two numbers are 2 and 9
2 x 9 = 18
9 is 7 greater than 2
