They ate 13 hot dogs in 2 minutes, so divide 13 by 2 to find out how many hot dogs he ate in 1 minute:

13 / 2 = 6.5 hot dogs per minute.

Now divide total hot dogs eaten by 6.5 to get the total time:

91 / 6.5 = 14 total minutes.

First you calculate the rate for how many hotdogs he could eat per minute:

13 / 2 = 6.5

Now you must apply the same rate to 91:

91 / 6.5 = 14

Answer:

\boxed{\bf~He~can~eat~91~hotdogs~in~14m.}

Hope it helped,

Happy homework/ study/ exam!

Which fraction is equivalent to 38%?<br> 3/8<br> 9/25<br> 19/50<br> 3 4\5
KonstantinChe [14]
In order to find a fraction, We know that a percentage is out of a 100. This means we can now place our fraction as:

38/100

In order to find the actual fraction, we will want to simplify. Lets find our least common factor and work down from there. Since we know that 2 can go into both of them, lets reduce by 2.

This means our fraction will now look like: 

19/50

Since 19 is a prime number and cannot be divided by anything but 1 and itself, we know that this is our simplified form. 

This means:

19/50 is the fraction equivalent to 38%.

X^2 + bx + 49 is a perfect squad trinomial what is one possible value of b?
ddd [48]

a perfect square trinomial, (x + y)² = x² + 2xy + y²

so, if we have the x of the bx, what is left is the b

the expression would have to be (x + 7)², since we have the 49 and the x²

so, what's left: x² + 14x + 49,

b = 14

<em>hope it helps :)</em>

What is the solution to -15x=90
il63 [147K]

Answer:

x = - 6

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable (x). Divide -15 from both sides

(-15x)/-15 = (90)/-15

x = 90/(-15)

Divide.

x = 90/-15

x = -6

*Remember that when you divide a negative number and a positive number, the result will be a negative answer.

-6 is your answer
