Answer:
4.5
Step-by-step explanation:
First we need to turn the ratio of 1 : 3 into a fraction
1:3 = 1/3
Next we need to square that fraction
1 x 1 = 1
3 x 3 = 9
Then we turn those numbers into a fraction
1/9
We turn the .5 into a fraction
.5/x
And cross multiply both fraction by each other
1/9 x .5/x
1 x X = X
9 x .5 = 4.5
So
4.5 = X
9(-6x-2)-7(-10x-2)
Simplify, by distributing the 9 and the -7
-54x-18+70x+14
Combine like terms
16x-4 is the simplified expression

1 mg = 0.001 grams. therefore 2000 mg = 2 grams
A quarter is .25 cents
A dime is .10cents
A nickel is .5cents
A penny is .01cent
3 quarters and 2 pennies=.77cents.
2 dimes and 1 nickel=.25cents
The answer is that her mom gave .77 cents on Monday and .25cents on Tuesday
If you were to add them together(.77+.25) it would be $1.02
