I can help u with one question,rest u can do it.
Pythagorean theorem is (hy)^2=(l)^2+(b)^2
Hypotenuse is the lingest side of a triangle
Answer:
x=2. y=1/2
Step-by-step explanation:
4x-2y=7. Equation 1
x+2y=3. Equation 2
Add the two equations
(4x+x) +(-2y+2y) =7+3
5x+0=10
5x=10 divide both sides by 5
X=2
Substitute x=2 in equation 2
2+2y=3
2y=3-2
2y=1. Divide both side by 2
Y=1/2
Answer:
Step-by-step explanation: We have to add how much time it took him to do all of his homework. To do this, we have to add 2/3 and 3/5.
First, we have to find a LCM between 3 and 5.
The LCM between those numbers are 15.
Next we find out what number to multiply 3 by to get 15, we multiply it by 5.
2 * 5 = 10
3 * 5 = 15
Next we find out what number to multiply 5 by to get 15, we multiply it by 3.
3 * 3 = 9
5 * 3 = 15
10/15+9/15=19/15
We are left off with 1 4/15
So it took him 1 hour and 4/15 minutes to do his homework.
10
Step-by-step explanation:
you can see it two ways 5×2 or 2×5 better to see it 5×2 cause it's simple 5 then 10 you just add more onto what's the number
