Answer:
check properly their must be something wrong with the question
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.
C. Because you have to look for the greatest number. Disregard whether it is negative or positive. Since you are looking for steepness. That does not matter.
Answer:F + S = 124
Step-by-step explanation:
Also, you want the total mixture to contain 8% vinegar so: .06F + .11S = .08(310)
Now, we can solve the system of equations using substitution.
F + S = 310
.06F + .11S = .08(310)
F = 310 - S [solve 1st equation for F]
.06(310 - S) + .11S = .08(310) [substitute into 2nd equation]
18.6 -.06S +.11S = 24.8
.05S = 6.2
S = 124
