Answer:
Step-by-step explanation:
y = 3x + 4, and
y = x + 2
------------------
Use the vale of y in the 2nd equation in the first:
y = 3x + 4
x + 2 = 3x + 4
-2x = 2
x = -1
Use this value of x (-1) in either equation to find y:
y = x + 2
y = -1 + 2
y = 1

Answer:Marcus jogged 7 miles while Elena jogged 8 miles.
Step-by-step explanation:
x + (x+1) = 15
2x+1=15
putting like terms together we get:
2x=15-1
2x=14
hence
x=14/2 = 7miles
therefore we conclude that Marcus jogged 7 miles while Elena jogged 8 miles.
Answer:
915
Step-by-step explanation:
18300 x 0.05 = 915
5%=0.05
V=24h
divide by 24 for both sides
V/24= 24h/24
Cross out 24 and 24, divide by 24 and then becomes 1*1*h= h
Answer: h= V/24
