Answer:
Order 5 pizza's. There is
1
2
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
1
4
of a pizza the 1 pizza feeds 4 students.
So the ratio of
pizza count
Student count
→
1
4
Need to have sufficient pizza for 18 students. The ratio will be constant so we have:
Let the count of pizzas be
p
pizza count
Student count
=
1
4
=
p
18
So we now have:
p
18
=
1
4
Multiply both sides by
18
giving:
18
×
p
18
=
1
4
×
18
18
18
×
p
=
18
4
But
18
18
=
1
p
=
18
4
=
4
1
2
You can not order
1
2
a pizza so the total pizza count is 5
Answer:
(2/3, 13/3) (Exactly one solution)
Step-by-step explanation:
Write these equations in a column:
x+y=5
2x-y=-3
Note that we can eliminate y immediately by adding these two equations together. We get:
3x = 2, so that x = 2/3.
Substituting 2/3 for x in the first equation, we get:
2/3 + y = 5. Clear out fractions by multiplying all three terms by 3:
2 + 3y = 15, or 3y = 13. Then y = 13/3, and the solution is
(2/3, 13/3) There is exactly one solution.
Answer:
the number of times Angela needs to fill the 1/4-cup measuring cup to pour 1/2 cup of milk is 2.
Complete question:
While making oatmeal cookies, Angela needs to add 1/2 cup of milk to her dough. However, she has only a 1/4-cup measuring cup. How many times does she need to fill the measuring cup to pour 1/2 cup of milk? The number of times Angela needs to fill the 1/4-cup measuring cup to pour 1/2 cup of milk is?
Step-by-step explanation:
Number of cups Angela needs to add to her dough = 1/2 cup of milk
The only measuring cup she has = 1/4-cup measuring cup.
To determine the number of times she needs to fill the measuring cup to pour 1/2 cup of milk, we would divide the 1/2 cup of milk by 1/4-cup measuring cup
= ½ ÷ ¼
= ½ × 4/1
= 4/2
= 2
Angela would need to fill 2 times
Therefore, the number of times Angela needs to fill the 1/4-cup measuring cup to pour 1/2 cup of milk is 2
