Answer:
h=-tr2-V
Step-by-step explanation:
V=thr2
V-h=tr2
-h=tr2-V
-tr2-V=h
therefore,
h=-tr2-V
The answer is 10
I'm going to list the locker numbers by round:
Evens) 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, etc.
2's) 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, etc.
5's) 5, 10, 15, 20, 25, 30, 35, 40, etc.
The first number to repeat is 10, so that would be the first locker Brandy opens.
Hope this helped :)
Answer:
-1/3
Step-by-step explanation:
21-7y=5y+25
12y=-4
y=-1/3
Answer:
=-22
Step-by-step explanation:
first you fix the x and y into the eqution.
5(-2)-4(3)
Mulitiply and divide (left to right)
5(-2)=-10
mulitply and divide (left to right)
4(3)=12
so the would make the problem look like this
-10-12
add and subtract (left to right)
-10-12=-22
Not sure if I’m understanding this wrong but for x you can multiply the top equation by -3 to get -12x-15y=-21 and the bottom by 4 to get 12x-8y=-48.
For y you can multiply the top equation by 2 to get 8x+10y=14 and the bottom equation by 5 to get 15x-10y=-60
