So
Total cost of the workbooks is d
And the number of workbooks is t
Therefore d = 95
95=19t
t=95/19=5
5 workbooks
Answer:Assuming you want the rate per one week.
1/2 ÷ 3/7 = x / 1
(1/2)(7/3) = x
7/6 = x
1 1/6 = x
The plant grows one and one-sixth inches in a week.
Step-by-step explanation:
These types of graphs have a set notation domain, which basically means that the points are whole number plot points, not continuous.
So the domain would be in curly braces, since it is a set notation, separated by commas.
{-1, 1, 3, 5, 7, 9}
The number of hours Jeremiah ironed = 10 hours
The number of hours Tristan ironed = 7 hours
<u>Step-by-step explanation</u>:
- Jeremiah can iron = 35 shirts per hour
- Tristan can iron = 20 shirts per hour
- Total work done by both = 490 shirts
Let 'x' be the number of hours Jeremiah ironed.
Let 'y' be the number of hours Tristan ironed.
x+y = 17 ------(1)
35x + 20y = 490 -------(2)
Multiply (1) by 20 and subtract (2) from (1),
20x + 20y = 340
-(<u>35x + 20y = 490</u>)
<u>-15x = -150 </u>
x = 150/15
x = 10
Substitute x=10 in (1)
10+y = 17
y = 7
