Answer: 11 and 24

Step-by-step explanation:

Given

There are 35- 50 cents and 20 cents coins

The total of them is 10.3 euros

Suppose no of 50 cents coins is x and 20 cents is y

so we can write

\Rightarrow 0.5x+0.2y=10.3\quad \ldots(i)

Also,

\Rightarrow x+y=35\quad \ldots(ii)

Solving (i) and (ii) we get

x=11; y=24

There are 11 fifty cent and 24 twenty cents coins

Answer:

x=6

Step-by-step explanation:

We can use ratios to determine the value of x

x           9

------ = ----------

10          15

Using cross products

15x = 9*10

15x = 90

Divide each side by 15

15x/15 =90/15

x = 6

Margarita [4]

Answer:

The answer to your question is width = 6 ft; length = 24 ft

Step-by-step explanation:

Data

Area = 144 ft²

width = w

length = l

The width is 1/4 of the length

Formula

Area = width x length = w x l

Length = 4 width     l = 4w

Process

1.- Substitute length in the first equation

                       Area = w(4w)

Simplify

                       Area = 4w²

2.- Solve for w

                      w = \sqrt{\frac{Area}{4}}

Substitution

                      w = \sqrt{\frac{144}{4}}

Simplification

                      w = \sqrt{36}

Result

                      w = 6 ft

3.- Find l

                       l = 4(6)

                       l = 24 ft
