<h2>
Hello!</h2>
The answer is:
The area of this figure is 946 square inches.
<h2>
Why?</h2>
We can see that the figure is composed by two rectangles with diferrent dimensions, so, to calculate the area of the entire figure.
So,
For the first rectangle, we have:
The area will be:
For the second rectangle, we have:
The area will be:
Now, calculating the area of the entire figure, we have:
Have a nice day!
Answer:
50 of D and 10 of C
Step-by-step explanation:
First of all, put this data into 2 equations.
You sold 60 items, so C+D=60
C is $5 so we can represent it by 5C
D is $7 so we can represent it by 7D
You made $400 total from C and D, so 5C+7D=400
We can use simultaneous equations to solve this.
To eliminate one of these variables, we'll multiply the first one by 5 to make it 5C like the other.
5(C+D=60) (make sure you multiply both sides.)
so 5C+5D=300
5C+7D=400
Now we solve it:
5C-5C+7D-5D=400-300
7D-5D=100
2D=100
D=50
Now we can substitute this with one of the equations to find C
C+50=60
C=60-50
C=10
so, (10x5)+(50x7)=400
The average of p, q, and r is 40. The average of a, b, c, and d is 5. What is the average of a, b, c, d, p, q, and r?

Answer:
20
Step-by-step explanation:
Average = sum of numbers divided by number of numbers
sum of p q and r: 40*3=120
sum of a b c and d: 5*4=20
sum of a b c d p q r: 120+20=140
average of a b c d p q r: 140/7, or 20
