Answer:

Perimeter 18.8

area 15

Step-by-step explanation:

Use pythageriums theorem

6^2 + 5^2 = c^2

I found the sides by counting squares

6^2 + 5^2 = 61

square root it to find the answer

7.8 is the missing side so now add it all together

7.8+6+5= 18.8

to find the area do 6 x 5/ 2

When Gene and Kelly were planning their trip to Paris, one United States dollar was worth about $\frac{7}{10}$ of a euro. Before

Andre45 [30]

Answer:

$280 dollars

Step-by-step explanation:

When they were leaving

$\$1 \approx \frac{7}{10}$ Euro\\Therefore:\\\$1000 \approx \dfrac{7}{10}\times 1000 =700$ Euro$

When they returned home, they brought 196 Euros.

$If\:\:\$1 \approx \frac{7}{10}$ Euro\\Then: 1 Euro $=\$ \dfrac{10}{7}\\\\$Therefore:\\\\196 Euros = \$ 196 \times \dfrac{10}{7} =\$280$

They brought back $280 dollars to the United States.

20/20=4,000,000

2/20=?

2/20×4,000,000÷20/20=400,000

20/20=4,000,00

3/20

3/20×4000000÷20/20=600,000

20/20=4,000,000

4/20

4/20×4,000,000÷20/20=800,000

20/20=4,000,000

5/20

5/20×4,000,000÷20/20=1,000,000

20/20=4,000,000

6/20

6/20×4,000,000÷20/20= 1,200,000

BRUH SOMEONE HELP ME <br><br> also explain:)

ANTONII [103]

Answer:

$x=7$

Step-by-step explanation:

So we have the function:

$w(x)=3x-7$

And we want to find x when w(x) is 14.

So, substitute 14 for w(x):

$14=3x-7$

Add 7 to both sides. The right cancels:

$21=3x$

Divide both sides by 3:

$x=7$

So, the value of x is 7.

The correct answer is the first option.
