For example, 3/5.
3/5 = 0.6.
1/2 = 0.5
2/3 = 0.6666
0.5 -- 0.6 -- 0.66666666
Answer:
(2, 9)
Step-by-step explanation:
y=2x+5
x=2 ⇒ y=2*2+5=4+5=9
so the point is (2, 9)
Answer:
2
Step-by-step explanation:
Divide 3.4 by 1.7 and you get 2
Answer:
60 oz of water to add
45 oz of 35% salt solution should be used
Step-by-step explanation:
Let x = amt no. ounces in the first solution
and 105 - x = amt no. of ounces in the second solution
Ist solution contains 0% salt
2nd solution contains .35(105 - x) salt
.15(105= amt of salt in mix
So.
amt of salt in 1st solution + amt of salt in 2nd solution = amt of salt in the mix
0 + .35(105 - x) = .15(105)
Let's get rid of the fractions by multipying thru the equation by 100
35(105 - x) = 15(105)
3675 - 35x = 1575
-35x = -2100
x = 60 oz of water to add
105 - 60 = 45 oz of 35% salt solution should be used
