7nadin3 [17]

Answer:

Katie needs to pay $27.9.

Step-by-step explanation:

Given;

Cost of per foot = $2.25

Number of flowers in her yard = 12.4 square foot

We need to find how much she needs to pay.

Solution:

Now we know that;

$1\ ft^2 = \$2.25$

So for $12.4 ft^2$ = Cost for $12.4 ft^2$ .

By using Unitary method we get;

Cost for $12.4 ft^2$ = $2.25\times12.4= \$27.9$

Hence Katie needs to pay $27.9.

Subtract j from 9, then subtract 3 from the result

Lera25 [3.4K]

Answer:

(9-j)-3

Step-by-step explanation:

Let's start from the beginning and subtract j from 9. Because the word "from" is used, 9 will be the first number and j will be the second number.

We have 9-j

Now, we have to subtract 3 from the final answer. So, we have (9-j)-3

Please solve asap pls x

mr Goodwill [35]

Answer:

$x=\frac{26}{5}$

Step-by-step explanation:

$\frac{10x+4}{7}=8$

<u>Multiply both sides by 7:</u>

$\longmapsto$ $\frac{7\left(10x+4\right)}{7}=8\times \:7$

$\longmapsto$ $10x+4=56$

<u>Subtract 4 from both sides:</u>

$\longmapsto$ $10x+4-4=56-4$

$\longmapsto$ $10x=52$

<u>Divide both sides by 10:</u>

$\longmapsto$ $\frac{10x}{10}=\frac{52}{10}$

$\longmapsto$ $x=\frac{26}{5}$
