Amber coaches both sports for 7 hours each day
v = volleyball hours
s = soccerball hours
7 hours in total, in which soccerball is 1 hour more than volleyball:
v + s = 7
s = v + 1
plug in v + 1 for s
v + s = 7
v + (v + 1) = 7
simplify
v + v + 1 = 7
2v + 1 = 7
2v + 1 (-1) = 7 (-1)
2v = 6
2v/2 = 6/2
v = 6/2
v = 3
Plug in 3 for v for one of the equations.
s = v + 1
s = (3) + 1
s = 4
Amber coaches 3 hours for volleyball, and 4 hours for soccer, making a total of 7 hours
hope this helps
Answer:
x = -3 and x = 9.
Step-by-step explanation:
2|x - 3| - 5 = 7
2|x - 3| = 12
|x - 3| = 6
x - 3 = 6
x = 9
-(x - 3) = 6
-x + 3 = 6
-x = 3
x = -3
Hope this helps!
Answer:
92,776
Step-by-step explanation:
I have 5 digits. My 9 is worth 9*10,000. My 2 is worth 2 thousand. One of my 7s is worth 70. The other is worth 10 times as much. My other digit is a 6. What number am I?
My 9 is worth 9*10,000 = 9 * 10,000
= 90,000
My 2 is worth 2 thousand = 2,000
One of my 7s is worth 70 = 70
The other is worth 10 times as much = 70 * 10
= 700
My other digit is a 6 = 6
The number is
90,000 + 2,000 + 700 + 70 + 6
= 92,776
Answer:
h=1
Step-by-step explanation:
4h=9h+13 ->changes sides so sign changes
4h+9h=13 ->normal adition
13h=13 ->divide
h=1
2 x (5-2)^3
2 x (3)^3
2 x 27
54
