Answer:
Step-by-step explanation:
From the first sentence x (the number) is 2 more than another number (y). So, x+2=y. The sum of the squares of the two numbers is 42, meaning that 
+
=42. First, we square root the ENTIRE equation to get rid of the square. If you do one thing to one side, you have to do it to the other. After this, we have x+2+y=
. Now, we subtract 2 from the other side to isolate the variable. You can isolate either one but normally I go for x. Now we have x+y=+2. Now, we want to get y to the other side so we subtract it from the left side and the right side which gives us x=-y++2. now we know what X is equal to. Now we plug in x for +=42, which gives us 
+=42. Now we only have one variable which is what we want. Next, we square root the entire thing to get rid of the squares, which gives us -y++4+y=. I got lost in my work. I must have done something wrong I cant find out. If anyone wants to pick up where I left off go ahead but there's a timer and I have one minute left. I cant finish the problem in a minute. I'm sorry and hopefully I lead you somewhere.
Answer:
Step-by-step explanation:
Let the number of jars is x.
<u>80 liters distributed, each jar has:</u>
<u>Redistribution with 4 less jars, each jar now has:</u>
<u>Each jar has now twice the amount:</u>
- 80/x*2 = 80/(x - 4)
- 2/x = 1/(x - 4)
- 2(x - 4) = x
- 2x - 8 = x
- x = 8
She prepared 8 jars at the start
17 seeds are left over because in the 7 holes she puts 2 seeds in each which if you multiply it it will equal to 14 and plus the three that she has left over and if you add 14 and 3 you get 17 seeds. hope this helps!
The formula of the perimeter of a rectangle is 2l+2w so look at the photo
He need to earn 48
Inequality : 80-32=x
