Solve the following equation:<br>m - m-1/2 = 1 - m-2/3

grigory [225]

Answer:

m = $\frac{7}{5}$

Step-by-step explanation:

m - $\frac{m-1}{2}$ = 1 - $\frac{m-2}{3}$

Multiply through by 6 ( the LCM of 2 and 3 ) to clear the fractions

6m - 3(m - 1) = 6 - 2(m - 2) ← distribute parenthesis on both sides

6m - 3m + 3 = 6 - 2m + 4 , that is

3m + 3 = - 2m + 10 ( add 2m to both sides )

5m + 3 = 10 ( subtract 3 from both sides )

5m = 7 ( divide both sides by 5 )

m = $\frac{7}{5}$

Jim is saving nickels, dimes and quarters to buy a baseball mitt. He has 12 more

Harrizon [31]

Answer:

36 quarters 48 dimes 64 nickels

Step-by-step explanation:

quarter = q

dime = q+12

nickel = 2q-8

$17 = 1,700 cents

(q)25 + (q+12)10 + (2q-8)5 = 1,700

25q +10q+120 +10q-40 =1,700

45q+80 = 1,700

45q = 1620

q= 36

36 QUARTERS x25 = 900cents

48 DIMES x10 = 480 cents

64 NICKELS x 5 = 320 cents

TOTAL 1,700 cents ($17)
