PLEASE HELP solve for x
Pepsi [2]

Hey there!

Perimeter is the combination of all the sides.

side+side+side+side= P

We know that P, or perimeter, is 14 yards.

And we know that one side is 4 yards.

4 * 2= 8 (we know two sides have to be the same)

14-8= 6

Now we have 6 yards left and two sides. So, we should divide by two.

6/2=3

x=3

I hope this helps!

For every quarter he spends, Reggie receives 50 food pebbles to feed the fish. Reggie has thrown 350 food pebbles into the fish
deff fn [24]

Answer:

7 quarters are spent for throwing 350 food pebbles in pond.

Step-by-step explanation:

Given:

Reggie receives 50 food pebbles for every quarter he spends.

Number of food pebbles he has = 350

Let the number of quarters spent for 350 pebbles be 'x'.

Now, using proportion and cross multiplication method, we can find 'x'.

<u><em>1 quarter is equivalent to 50 pebbles thrown in pond.</em></u>

<u><em>So, 'x' quarters is equivalent to 350 pebbles thrown in pond.</em></u>

\frac{1}{50}=\frac{x}{350}\\\\Cross\ multiplying\\\\50x=350\\\\x=\frac{350}{50}\\\\x=7

So, 7 quarters are spent for throwing 350 food pebbles in pond.

Vesnalui [34]

Answer:

A

Step-by-step explanation:

Just like the last time that you asked this question, when you multiply the x^2 part of the parabolic function by a certain coefficient, the graph is stretched by that amount. When you add a certain amount, the graph is shifted up that much. Hope this helps!

Did I do this problem correctly??
DaniilM [7]

You're correct in the x parts where each is +3

You're incorrect in the y part

5 - 6 = -1

5 - 4 = 1

So the first one should be -6

From there, its +6

-1 + -6 = -7

-7 + -6 = -13
