Answer:
4 boxes bc they're 12 in a dozen
24.56m. your problem should look like a^2+29^2=38^2. you the. have a^2+841=1444. you subtract 841 from 1444 and are left with 603. < this is a^2. you take the square root of that and get 24.56
Answer:
(2,1)
Step-by-step explanation:
3x+y = 7
-2x +y = -3
Solve the second equation for y by adding 2x to each side
-2x+2x +y = -3+2x
y = -3 +2x
Substitute into the first equation
3x+ (-3+2x) = 7
Combine like terms
5x -3 = 7
Add 3 to each side
5x-3+3 = 7+3
5x = 10
Divide by 5
5x/5 = 10/5
x=2
Now we need to solve for y
y = -3 +2x
y = -3 +2(2)
y = -3+4
y =1
