Answer:
M is 1.5
Step-by-step explanation:
Use M = 1/O
Replace 1 with a letter such as K
So you use M = K/O
Substitute values
0.5 = K/6
To get K times 0.5 by 6
You get 3
So K=3
Use the equation from the start to find M
M=3/2
M IS 1.5
Usually when you see f(x) or as yours is f(6) f with parenthesis is just a fancy way of saying y= so basically you plug six in for the x values of your question
Answer:
only E is false except that all are true
A,B,C,D are correct
J=15b/10g
S=21b/g w/ the ratio 3/2 (15/10=3/2)
1) Form an equation (21/g=3/2).
2) Since you are trying to find the denominator, multiply 3/2 so that the numerators are the same (3×7=21 2×7=14).
3) The answer will be whatever the denominator is at the end.
The answer is there are 14 girls in Steven's class.
Answer:
117
Step-by-step explanation:
Let d represent the number of stamps Derek had at first. After he gave 1/9 of his stamps to Ahmad, Ahmad had (d -104) +(d/9). Derek had 4 times this number after giving away d/9 stamps:
(d -d/9) = 4((d -104) +d/9)
(8/9)d = 4d -416 +(4/9)d
416 = (32/9)d . . . . add 416 -8/9d
117 = d . . . . . . . . . . multiply by 9/32
Derek had 117 stamps at first.
_____
<em>Check</em>
1/9 of Derek's collection is 13 stamps. 104 less than Derek's collection is 13 stamps.
So, Ahmad started with 13 stamps and was given 13 stamps by Derek. Meanwhile, Derek started with 117 stamps and gave away 13, so ended with 104 stamps. That number (104) is 4 times Ahmad's new number (26), as it should be.
