Step-by-step explanation:
You time the 4 by the amount of times the 6 is timed.
Answer:
30,000
Step-by-step explanation:
5,000 in 6 months therefore 10,000 in one year and 30,000 in 3 years
Answer:
x ≥ 4
Step-by-step explanation:
-4(8 - 3x) ≥ 6x - 8
-32 + 12x ≥ 6x - 8
-32 + 8 ≥ 6x - 12x
-24 ≥ -6x
x ≥ 24 / 6
x ≥ 4
Answer: To make a 310mL mixture that contains 8% vinegar, use 186mL of the first brand and 124mL of the second brand.
Step-by-step explanation:We want the total mixture to be 310mL so: F + S = 310
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
F + 124 = 310 [substitute answer for S back into original equation]
F = 186
