The square below represents one whole.

kupik [55]

Answer:

$\text{Shaded area as fraction}=\frac{81}{100}$

$\text{Shaded area as decimal}=0.81$

$\text{Shaded area as percent of the whole}=81\%$

Step-by-step explanation:

Please consider the attached image as the given square.

We are asked to express the shaded area as a fraction, a decimal, and a percent of the whole.

We can see that in our figure there are 100 squares as there are 10 rows and each row contains 10 squares.

We can also see that there are 81 shaded squares out of 100 squares, so we can represent it as a fraction as:

$\frac{\text{Shaded squares}}{\text{Total squares}}$

$\text{Shaded area as fraction}=\frac{81}{100}$

To convert the shaded area into decimal, we need to divide 81 by 100.

$\text{Shaded area as decimal}=0.81$

To convert the shaded area into percent, we need to multiply 0.81 by 100.

$\text{Shaded area as percent of the whole}=0.81\times 100\%$

$\text{Shaded area as percent of the whole}=81\%$

3(x+10)=2(2x+16) help please & thank you

andrew-mc [135]

In this question, you have to isolate <em>x</em>.

First, use the distributive property.

$3x+30=4x+32$

Now that you have distributed, subtract the constants.

Juanita is planting a flower garden. She wants to plant 24 tulips, and twice as many daffodils as tulips. A tulip plant costs $3

slavikrds [6]

Answer:

The total cost is $\$168$

Step-by-step explanation:

Let

x-----> the number of tulips

y-----> the number of daffodils

C-----> the total cost

we know that

$x=24\ tulips$

$y=2x$

substitute the value of x

$y=2(24)=48\ daffodils$

Find the total cost

$C=3x+2y$

substitute

$C=3(24)+2(48)=\$168$

Determine if the following system of equations has no solutions ......................

topjm [15]

Answer:

No solutions

Step-by-step explanation:

3x+4y=-4

15x+20y=-22

——————————

-5(3x+4y)=-5(-4) multiply 1st equation by -5 so you can eliminate the variables

-15x-20y=20. Modified 1st equation

15x+20y=-22. 2nd equation

0+0=-2. Added two equations together

since 0 does not equal -2, there is no solution.
