First we're gonna convert these fractions into fractions with a common decimal.

x + 4/7 = 3/8

4/7 = 32/56

4 * 8 = 32

7 * 8 = 56


3/8 = 21/56

3 * 7 = 21

8 * 7 = 56

Now we have x + 32/56 = 21/56

<em><u>Subtract both sides by 32/56</u></em>

x = -11/56

The mass of a ball is 128 g. It has a density of 0.5 g/cm³.
liraira [26]

Answer:

The volume of the ball is 256 cm³

Step-by-step explanation:

we know that

The density is equal to the ratio of the mass by the volume

D=m/V

Solve for V

The volume is equal to the ratio of the mass by the density

V=m/D

In this problem we have

m=128 g

D=0.5 g/cm³

substitute

V=128/0.5=256 cm³

Over the course of a month, Katniss caught three times as many squirrels as deer. She also caught five less rabbits than squirre
natta225 [31]

Answer:

10 rabbits

Step-by-step explanation:

Let us represent

Number of rabbits = x

Number of squirrels = y

Number of deer = z

Katniss caught three times as many squirrels as deer.

y = 3z

She also caught five less rabbits than squirrels.

y = x - 5

The total number of animals she caught is ten more than four times the number of deer caught.

x + y + z = 4 × z + 10

x + y + z = 4z + 10

How many rabbits did Katniss catch?

Number of rabbits = x

We make x subject of the formula

x + y + z = 4z + 10

x = 4z + 10 - y - z

y = 3z

x = 4z + 10 - 3z - z

x = 4z - z - 3z + 10

x = 4z - 4z + 10

x = 0 + 10

x = 10

Therefore, the number of rabbits Katniss caught is 10 rabbits
