Answer:

Step-by-step explanation:

4/7 x + 70 cm^3 = 3/4 x Subtract 4/7 x from both sides

3/4 x - 4/7 x = 70 cm^3 The lowest common denominator is 28

$\frac{3*7*x}{4*7} - \frac{4*4x}{4*7} = 70 cc\\\frac{21*x}{28} - \frac{16*x}{28} = 70 cc\\\frac{5x}{28}= 70cc\\$

5x = 70*28

5x = 1960 Divide by 5

x = 1960/5

x = 392 cc

Jeo is comparing the price of different boxes of cereal. One box has 16 oz. and costs $3.50. Another costs $3.89 for a 24 oz. bo

velikii [3]

Answer:

The difference in cost, in dollars, per ounce between the two boxes of cereal is $0.06.

Step-by-step explanation:

☆Let's solve using proportion.

☆One box:

$\frac{16 \: oz.}{3.50 \: dollars} = \frac{1 \: oz.}{x} \\ \\ \frac{3.50}{16} = \frac{16x}{16 } \\ \\ 0.22 = x$

☆Another box:

$\frac{24 \: oz.}{3.89 \: dollars} = \frac{1 \: oz.}{x } \\ \\ \frac{3.89}{24} = \frac{24x}{24} \\ \\ x = 0.16$

☆All we need to do is subtract: $0.22 - 0.16 = 0.06$

☆The difference in cost, in dollars, per ounce between the two boxes of cereal is $0.06.
