Answer:

c + p = 100

11.50c + 13.00p = 1255

Step-by-step explanation:

The first equation represents the total number of pizzas, and determines how many were cheese or pepperoni,

The second equation represents the total cost of the pizzas, and determines how much each type of pizza contributes to the total cost.

Answer:

c + p = 100

11.50c + 13p = 1255

Step-by-step explanation:

c = number of cheese pizzas

p = number of pepperoni pizza

If the school principal ordered 100 pizzas, then the equation would be...

c + p = 100

Since cheese pizzas cost $11.50 and pepperoni pizzas cost $13.00, then you would plug them into an equation where they equal to the total cost, $1255.

11.50c + 13p = 1255

So, your answer is letter choice C.

HELPPPPP PLEASEEEE!!!!!! Just number 9

$\text{Hey there!}$

$\text{Equation for company \#1: \$42 + \$0.05x}$

$\text{Equation for company \#2 \$ 0.08}$

$\text{Now, let's solve for your equations, shall we?}$

$\text{First set the overall equation up.}$

$\text{42 + 0.05x = 0.08x}$

$\text{Which is reverse back to: 0.08x - 0.05x = 42}$

$\text{0.08x - 0.05x = 0.03x}$

$\text{New equation (for now) 0.03x = 42}$

$\text{Divide each term by 0.03}$

$\dfrac{\text{0.03x}}{0.03}=\dfrac{42}{0.03}$

$\text{Cancel out:\ } \dfrac{\text{0.03}}{0.03}\text{ because it equals 1}$

$\text{Keep:\ }\dfrac{42}{0.03}\text{ because it helps us solve for our answer!}$

$\dfrac{42}{0.03} = 42\div0.03 \rightarrow 1,400$

$\text{Total: 1,400 pgs. (pages)}$

$\boxed{\boxed{\text{\bf{Answer should be:1,400 pages}}}}\checkmark$

$\text{Good luck on your assignment and enjoy your day!}$

Simplify the following expression:

Salsk061 [2.6K]

Simplification form of the provided expression is -x⁴-2x³+2x+5 option (B) is correct.

<h3>What is an expression?</h3>

It is defined as the combination of constants and variables with mathematical operators.

The options are:

A) -x⁴ - 2x - x + 2

B) -x⁴ - 2x³ + 2x + 5

C) -2x³ + 1

D) -x - 2x² + 2x + 5

We have an expression:

= (x + 3) - [(x + 2)(x³ - 1)]

$\rm =x+3-\left(x+2\right)\left(x^3-1\right)$

$\rm =x+3-x^4+x-2x^3+2$

$\rm =-x^4-2x^3+2x+3+2$

$\rm =-x^4-2x^3+2x+5$

Thus, simplification form of the provided expression is -x⁴-2x³+2x+5 option (B) is correct.

Julie scored 42 goals at soccer practice her ratio to goals to misses is 6:5 how many times did she miss

Bingel [31]

Answer:

35 times

Step-by-step explanation:

Since the ratio of goals to misses are 6:5

Your ratio would be

5/6 = 42/x

Let's cross multiply

42×5 is 210

divide 210 by 6 and you'll get 35

She missed 35 times.
