Find the ratio and proportion
There are 6,840 different combinations of people for president, secretary, and treasurer, assuming that each person may have a single job at a time.
Start with 20 candidates for president.
That leaves 19 people for secretary.
And there are 18 people remaining for treasurer.
20 • 19 • 18 = 6,840
Answer:
y = x - 8
Step-by-step explanation:
In the equation for slope, y = mx + b,
your slope being 0 makes the equation 'x' or 0x but x is preffered.
Your why would be -8 because there is no x in the point and it is a negative number.
Answer:
Dimensions of rectangle = <u>23 cm x 5 cm</u>
Step-by-step explanation:
<u>Equations we can form</u>
⇒ 2L + 2W = 56
⇒ L + W = 28
- Length is 8 more than 3 times its width
⇒ L = 3W + 8
<u>Substitute in previous equation</u>
⇒ 3W + 8 + W = 28
⇒ 4W = 20
⇒ W = <u>5 cm</u>
<u></u>
⇒ L = 28 - 5 = <u>23 cm</u>
