Answer:
yes
Step-by-step explanation:
it's a rule that 3,4,5 is a right triangle but use pathagorean to prove
3x3 + 4x4 = 5x5
9+16 = 25
U is 10. If you subtract 11 first to get the variable and it's coefficient on its own, you see that 3u=30. To get the u on its own, you divide both sides by three. This gives you u=10
Since 5 of the 8 students are boys, the fraction would be 5/8. The fraction would roughly be around 63%
6x+19.98=200
200-19.98=6x
X= 200-19.98/6
= solve for it.
Answer:
16x -12y = 4
15x +12y = 27
Step-by-step explanation:
4x-3y = 1
5x+4y=9
Multiply the first equation by 4
16x -12y = 4
Multiply the second equation by 3
15x +12y = 27
