Answer:
7x + 14y
Step-by-step explanation:
7(x + 2y)
Multiply 7 by the values inside the parenthesis (x + 2y)
7x + 14y
Hope this helps :)
Let's start with day 1:
We know that Joe practiced from 6:30 to 7:05
An hour is 60 minutes
Joe practiced for the 30 minutes left in that hour and 5 minutes into the next
30+5=35
So, he was playing for 35 minutes on the first day
Now, we can do the same thing for the second day:
He started at 3:55 and ended at 4:15
An hour is 60 minutes
<span>Joe practiced for the 5 minutes left in the hour and the first 15 minutes of the next hour
</span>
5+15=20
Now we want to add the number of minutes he practiced for both days
35+20=55 minutes
Answer:
Step-by-step explanation:
Let E = Erasers and P = Pencils
4E + 2 P = $16…(1)
3E + 1P = $10.50…(2)
Multiply (2) by 2 to make Pencils in (1) and (2) equal.
6E + 2P = $21…(3)
Subtract (3) from (1) to eliminate P
2E = $5 => Erasers = $2.50 each
Substitute this value for Erasers into (3)
6 * $2.50 + 2P = $21
2P = $21 - $15 = $6 => Pencils = $3
Therefore 5 Erasers + 3 Pencils cost
5 * $2.50 + 3 * $3 = $12.50 + $9 = $21.50
The length of the diagonal of the garden with 19.6 square feet and 4.3 length is : 6.3 feet
<h3>What is a rectangle?</h3>
A rectangle is a quadrilateral with four sides and four vertices each of angle 90°.
Analysis:
Area of rectangle: 19.6 square feet
length of one side = 4.3 feet
width of one side = Area/length = 19.6/4.3 = 4.6 feet
the diagonal and width and length of a rectangle for a right angle triangle.
To find the diagonal, we use Pythagoras theorem
= 
+ 
= 
+ 
= 39.7
diagonal = 
= 6.3 feet
in conclusion, the diagonal of the rectangular garden is 6.3 feet
