I am coming to the rescue hehehe

So, she has drove 19 miles already so
739 - 19 = 720
720/47= 15.320 ~ about 15 hours
15 hours and 20 minutes
The hours you would write is 15

739-19/47
739-19=720
720/47=15.319
15.319 rounded = 15 hours and 29 minutes

Pizza Palace and Saucy Sam’s both offer food delivery. Both have a deal for large pizzas. You have to buy a lot of pizzas for yo

pochemuha

Answer:

Now lets add up how much it would cost for a SINGLE pizza at both pizza places, which I am rounding up to the next dollar for this.

Step-by-step explanation:

Pizza Palace:

5 + 9 = 14

Meaning, if you were to get many pizzas, just a single one delivered costs 14 bucks, but all you have to do to add more pizzas to it is:

5 + 9p = ?, where p is the number of pizzas ordered

Saucy Sam's:

5 + 12 = 17

Meaning, if you were to get many pizzas, a single one delivered costs 17 bucks, but all you have to do to add more pizzas to it is:

5p + 12 = ?, where p is the number of pizzas ordered

BUT, heres where it tricks you, lets take both equations and choose a number that equals P. We can choose........ 10.

5 x 10 + 12 = 62

This means, that 10 pizzas of Saucy Sam's costs 62 dollars

5 + 9 x 10 = 95

This means, that 10 pizzass of Pizza Palace costs 95 dollars.

Saucy Sams has the best price.

ASAP GUYS PLEASE I NEED UR HELP THIS IS SO HARD<br> Solve: 5 − 7 ( z + 1 ) = 7 ( − 9 − 3 z )

pantera1 [17]

Answer:

$-\frac{61}{14}$

Step-by-step explanation:

Question: 5 - 7(z+1) = 7(-9-3z)

We multiply the number in front of the bracket first, since that is multiplication.

--> 5 -7z -7 = -63 - 21z

--> -7z -2 = -63 - 21z

Now, we move all the z and all the numbers to each side.

--> -7z +21z = -63 +2

--> 14z = -61

--> z = -61/14

This cannot be simplified further, so z is -61/14.
