Answer:

You should try the distributive property of multiplication:

3(2x+7)

=

3 x 2x = 6x

3 x 7 = 21

Therefore:

6x + 21

Answer:

6x+21 (Maybe)

Are you doing the buddy method, how is your teacher wanting to do this, When you respond I might have the correct answer

(buddy method) Multiply the 2x and 7 by the 3 giving you 6x+21 and then that's it you cant do anything else but I don't know if that's how you're teacher wants it done.

-4*2(3x-7)
-8(3x-7)
8 times 4 is 24 so it would be negative 24
so 3 times 16.3=48.9 then you add 7 which rounds it off it 56
so x is 16.3 thats how you get this expession

Answer:

527.52 square inches.

Step-by-step explanation:

The formula for the surface area of a cylinder is $2\pi r h + 2\pi r ^2$ , which in this case is $2\pi \cdot 7 \cdot 5 + 2\pi \cdot 49\approx 527.52$ square inches. Hope this helps!

Step-by-step explanation:

It is given that,

The running trail in the local park is 3.416 miles long. If the park board were planning to extend the trail by 1.34 miles.

We need to find the new length of the running trial. It is equal to the sum of length of running trail and the extended length. So,

l = 3.416 +1.34

l = 4.756 miles

So, the new length of the running trail be 4.756 miles

Answer:

Part a) $\frac{132}{89}$

Part b) 132:89 vs 132 to 89

Part c) $\frac{66}{7}$

Part d) 66:7 vs 66 to 7

Step-by-step explanation:

Let

x ----> the number of boys

y ----> the number girls

z ----> the number of adults

we have

x=132, y=89, z=14

Part a) Write the ratio of the number of boys to the number of girls.

To find the ratio of the number of boys to the number of girls, divide the number of boys by the number of girls

so

$\frac{x}{y}$

substitute

$\frac{132}{89}$

Part b) Write the same ratio using another form (A: B vs. A to B)

we have

$\frac{132}{89}$

The other form is

132:89 vs 132 to 89

Part c) Write the ratio of the number of boys to the number of adults

To find the ratio of the number of boys to the number of adults, divide the number of boys by the number of adults

so

$\frac{x}{z}$

substitute

$\frac{132}{14}$

Simplify

$\frac{66}{7}$

Part d) Write the same ratio using another form

The other form is

66:7 vs 66 to 7
