Answer:
7
Step-by-step explanation:
insert the numbers and divide
-4(-7)= 28
2^2= 4
28/4= 7
10 cupcakes in total
1/5 of 10 is 2/10 so 2 cupcakes are chocolate
2*0.45=$0.90
Dora spent $0.90 on chocolate cupcakes
18x-3=4x+11
-5 -4
14x-3=11
+3+3
14x=14
x=1 answer =1
Answer:
is the algebraic expression to represent the situation.
Step-by-step explanation:
Given:
Some students equally share 2 baskets of apples.
Each basket has 12 apples.
To Find:
An algebraic expression to represent the situation = ?
Solution:
Let the number of students be x
The number of apple each one gets be y
then it is said that there are 12 apples in one basket.
So in two basket there will be
=> 
=> 24 apples
This 24 apples is to be shared among x students, so
Each student will get
The first thing we must do for this case is to look for the area of each rectangle.
We have then:
A1 = (40) * (x)
A2 = (1.25 * 40) * (y)
Then, we have the following relationship between areas:
"the area of Q is 10% less than the area of p"
A2 = 0.9 * A1
Substituting values we have:
(1.25 * 40) * (y) = 0.9 * ((40) * (x))
We rewrite:
50y = 36x
The relationship x: y is:
x / y = (50) / (36)
Simplifying:
x / y = (25) / (18)
Answer:
the ratio of x:y is:
25:18
