Solve the inequality r-(-5)>-2

Mathematics
1 answer:
Jet001 [13]3 years ago
7 0

Answer:

r>-7

Step-by-step explanation:

Solving an inequality is similar to solving an equation. To solve for r, isolate it. Whatever you do to one side, do to the other. Remember that a negative and a negative equal a positive, thus one side of the inequality becomes r + 5. Then, subtract both sides by -5 to find the answer.

r-(-5) >-2\\r+5>-2\\r>-7

A collection of nickels, dimes and quarters totals $6.00.  If there are 52 coins altogether and twice as many dimes as nickels,
VashaNatasha [74]
D=2n:  there are twice as many dimes as nickels.

n+d+q=52:  a total of 52 coins, using d from above in this gives you:

n+2n+q=52  combine like terms on left side

3n+q=52  subtract 3n from both sides

q=52-3n

Then you are told that the coins have a total value of $6 which is equal to 600 cents.  So we can say:

25q+10d+5n=600  divide all terms by 5

5q+2d+n=120, and from earlier we saw q=52-3n and d=2n so you have:

5(52-3n)+2(2n)+n=120  expanding...

260-15n+4n+n=120  combining like terms

260-10n=120  subtract 260 from both sides

-10n=-140  divide both sides by -10

n=14, since q=52-3n and d=2n

q=(52-3(14))=52-42=10 

d=2(14)=28

So there are 10 quarters, 28 dimes, and 14 nickels or as your choices put it:

q=10, d=28, n=14  (the correct answer is d.)
