Answer: 46.4285 = x

Step-by-step explanation: Reading through the problem we have <em>39 is</em>, that's <em>39 equals</em>, <em>84%</em>, 84/100, <em>of</em>, <em>times</em>, <em>what number</em>, <em>x</em>.

So we have the equation 39 = 84/100 · x.

Reducing the 84/100 to 21/25, we have 39 = 21x/25.

Multiplying both sides by 25 to get rid of the fraction,

we have 975 = 21x.

Now divide both sides by 21 to get <em>46.4285 = x</em>.

This means that 39 is 84% of 46.4285.

What is the multiplicative inverse of the sum of 1/3 + 1/5 ? Express in simplest form
Dima020 [189]
\frac{8}{15}

My Work/Reasoning:
First we find the sum of 1/3 and 1/5. \frac{1}{3} + \frac{1}{5} = \frac{5}{15} + \frac{3}{15} = \frac{8}{15}
Then, we find the multiplicative inverse, I guess it's also known as the reciprocal. \frac{8}{15} turns into \frac{15}{8}
Finally, we simplify. \frac{15}{8}=1 \frac{7}{8}

Mr. Smith wants to order some pizza and cheese pizza cost $11 and pepperoni pizza cost $12.50 if you bought 13 pieces total and
Triss [41]

Answer: Mr Smith bought 7 pepperoni pizza

Step-by-step explanation:

Step 1

cost of cheese pizza  =$11

pepperoni pizza cost =$12.50

let number cheese pizza be represented as c

and number of pepperoni pizza be represented as p

such that the total number of pizza  bought which equals 13 can be represented as

c+ p= 13

and total cost of both pizza  can be expressed as

11c+ 12.50p =153.50

Step 2 Solving

 c+ p= 13

11c+ 12.50p =153.50

By elimination method, Multiply equation 1 by 11 and subtract the new equation from equation 2

11c+ 12.50p =153.50

11c+ 11p=143.

1.5p =10.5

p= 10.5/ 1.5 =7

c+ p= 13

c= 13-p =13-7=6

Therefore Mr Smith bought 6 cheese pizza and 7 pepperoni pizza
