Answer:

Step-by-step explanation:

Answer:

Order 5 pizza's. There is

a pizza left so someone gets an extra portion! Or it is split evenly!

Explanation:

No matter how you present this, the underlying principle is that of ratio.

If each pupil gets

of a pizza the 1 pizza feeds 4 students.

So the ratio of

pizza count

Student count

→

Need to have sufficient pizza for 18 students. The ratio will be constant so we have:

Let the count of pizzas be

pizza count

Student count

So we now have:

Multiply both sides by

giving:

But

You can not order

a pizza so the total pizza count is 5

Three packages of pens and one box of paper cost $26. Two packages of pens and 7 boxes of paper cost $49. How much does one box

algol13

Answer:

5 dollars

Step-by-step explanation:

Let's call the price of a package of pens n, and the cost of a box of paper r.

3n+r=26

2n+7r=49

Multiply the first equation by 7:

21n+7r=182

Subtract the second equation from the first:

19n=133

Divide both sides by 19 to isolate n:

n=7

Plug this back in to find the value of a box of paper:

3(7)+r=26

21+r=26

r=5

Hope this helps!

Monique is factoring the expression 4 x + 16 x y. Her work is shown below. Factors of 4x: 1, 2, 4, x Factors of 16xy: 1, 2, 4, 8

Anika [276]

Answer:

Monique made an error when writing the factored expression.

Correct factored

expression=4x(1+4y)

Step-by-step explanation:

factoring the expression 4 x + 16 x y.

Factors of 4x: 1, 2, 4, x

Factors of 16xy: 1, 2, 4, 8, 16, x, y

GCF: 4x

Factored expression: 4 x (0 + 4 y)

Monique made an error when writing the factored expression.

The correct factored expression should be:

4x+16xy

=4x(1+4y)

Contrary to 4x(0+4y)

Correct factored

expression=4x(1+4y)
