Answer:
11+2x
Step-by-step explanation:
Hey there. So basically, find out how much the pencils and notebooks cost first.
The notebooks cost = $3.25
The pencils cost = $0.50
Then, think about what you need to figure out in this problem.
Jake has $20. You need to find how many notebooks Jake can buy in maximum after buying 8 pencils.
If Jake buys 8 pencils that costs $0.50 each, he spends $4 on the pencils.
So now, to find out how many notebooks he can buy, do 20 minus 4.
Jake's got $16 left.
If the notebooks cost $3.25 each, we need to find out how many notebooks he can buy by dividing them. So, 16 divided by 3.25 equals 4.923... and so on.
That means, Jake can buy 4 notebooks with his remaining money.
Answer:
X = 0
Y = -3
Step-by-step explanation:
In this situation you would choose elimination.
-6x+y=-3
7x-y=3
---------------
x = 0
plug back in to find y
(-6)(0) + y = -3
0 + y = -3
y = -3
plug in to other equation for double check
7(0) - (-3) = 3
0 + 3 = 3
3 = 3
Hope this helps
First, let's put all of the variables together.
4m + 5m + 5 + 40 = 180.
Add them.
M is the same multiplier, so we can add 4 and 5 together to make 9m.
Add 5 and 40.
9m + 45 = 180.
From here, we can go two ways. I will show the first way, which is my personal preference.
We want to get rid of the coefficient on m to isolate it, so we must divide it by its coefficient. The coefficient on m is 9. So, divide m by 9. We must also divide everything else by 9.
9m/9 = 1m
45/9 = 5
180/9 = 20
Plug it in--
m + 5 = 20.
Subtract the 5 from both sides to isolate m.
m = 15.
It’s the first box goes to the 3rd missing thing and the second goes to the 4th and the 3rd goes to the 1st and 4th goes to the 2nd I think if that makes sense
