Answer:
see below
Step-by-step explanation:
<u>Given:</u>
Binomial 7 - 25f
- 7 = constant, it is a number as a term
- 25 = coefficient, it is a number which is multiplied by a letter (variable)
- f = variable, which is normally identified as a letter, it is degree one
F(h) = 40h + 120....when f(h) = 200
200 = 40h + 120
200 - 120 = 40h
80 = 40h
80/40 = h
2 = h <=== 2 hrs
Answer:
you have to multiply 23 by 7 and divide 20
Step-by-step explanation:
Answer:
yes it
Step-by-step explanation:
1/2y=1
y=1 x 2 (because e do to multiply the one by 2/1 to get y alone)
y=2 ( if y is always equal to two there is no variation meaning it is linear)
Answer:
The area of the rectangle is 2820 square inches. The length is 60 inches. The width is 47 inches.
Step-by-step explanation:
Since we know the equation to find the width, we have to set them both to the perimeter of 90 inches. We will use the variable <em>x</em> to represent the length.
<em>x + x - 30 = 90</em>
<em>2x - 30 = 90</em>
<em />
You would then subtract 30 from both sides.
<em>2x = 60</em>
Divide by 2 on both sides, finding that the length (x) is 30 inches.
<em> x = 30 inches.</em>
<em></em>
Then, subtract 13 inches from the length to find your width.
<em>60 - 13 = 47 inches</em>
<em />
To find your area, you would multiply both of your factors (length and width) together.
<em> 60 x 47 = 2,820</em>
<em />
And those are your answers!
