Answer:
A. 2m - 16+3=17
2m = 17+16-3
2m = 30
m=30/2=15
B. 2(m-8) = 17-3
m-8 = 14/2
m = 7+8 = 15
Step-by-step explanation:
1.886 to the nearest hundredth would be 2.
Answer:
105 cc of 7% solution
245 cc of 17% solution
Step-by-step explanation:
If x = volume of 7% solution, and y = volume of 17% solution, then:
x + y = 350
0.07x + 0.17y = 0.14(350)
Solve with substitution:
0.07x + 0.17(350 − x) = 0.14(350)
0.07x + 59.5 − 0.17x = 49
10.5 = 0.10x
x = 105
y = 245
