Answer:

Step-by-step explanation:

Roberts's father=4x

Robert=x

After 5 years, the ages will be

4x+5 and x+5 because we just simply add 5 years to their ages

It says that the father will be 3x older. So,

3(x+5)=4x+5. --this is the equation

3x+15=4x+5

-5 -5

3x+10=4x

-3x -3x

x=10

A jeweler is dividing

tatuchka [14]

Question:

A jeweler is dividing 3/8 of a pound of rubies among 4 lots. What part of a pound will each lot weigh? A.1/4 B.1/8 C.1/16 D.3/32

Answer:

Option D

Each lot weight $\frac{3}{32}$ part of pound

Solution:

Given that,

A jeweler is dividing 3/8 of a pound of rubies among 4 lots

To find: part of a pound each lot weigh

From given,

$\frac{3}{8} \text{ of a pound } = 4 lots$

Let "x" be the part of a pound each lot weigh

Therefore,

$\frac{3}{8} \text{ of a pound } = 4 lots\\\\"x" part = 1\ lots$

This forms a proportion and solve by cross multiplying

$\frac{3}{8} \times 1 = 4 \times x\\\\x = \frac{3}{32}$

Thus, each lot weight $\frac{3}{32}$ part of pound
