Answer:

$a=63$

Step-by-step explanation:

$14=\frac{2a}{9}$

Switch sides:

$\frac{2a}{9}=14$

Multiply both sides by 9:

$\frac{9\cdot \:2a}{9}=14\cdot \:9$

$2a=126$

Divide both sides by 2:

$\frac{2a}{2}=\frac{126}{2}$

$a=63$

2. George estimates that each bale of hay in his field weighs 62.5 pounds on

saw5 [17]

Answer:

4 trips

Step-by-step explanation:

there are 892 bales of hay

each one weighs about 62.5 pounds

892 * 62.5 = 55,750

George's truck can only carry 8 tons

1 ton = 2,000 pounds

2,000 * 8 = 16,000 pounds

So,

55,750 / 16,000 = 3.484375

But since you can't make 3.484375 trips in a truck, round it up.

3.484375 rounded up equals 4

George has to take 4 trips

Azul has 4 green picks and no orange picks you add orange picks so that there are 2 orange picks for every 1 green pick how many

tino4ka555 [31]

Answer:

There would be 12 total picks.

Step-by-step explanation:

In order to find this, create a proportional equality in which the top of the equation is the number of orange picks and the bottom is the number of green picks.

2/1 = x/4

Now we cross multiply to find out the total number of picks.

1*x = 4*2

x = 8

Now that we have the number of orange picks, we add to the number of green picks for the total number.

4 + 8 = 12

Using appropriate properties find: 2/3 × 3/4 + 3/7 × 3/4

Viktor [21]

Answer:

$\frac{23}{28}$

Step-by-step explanation:

$\frac{2}{3} \times \frac{3}{4} + \frac{3}{7} \times \frac{3}{4}$

$= > \frac{3}{4} ( \frac{2}{3} + \frac{3}{7} )$

$= > \frac{3}{4} \times \frac{23}{21}$

Reducing 3 from numerator and denominator,

$= > \frac{23}{4 \times 7} = \frac{23}{28}$
