Answer:
a. 14 is a coefficient, and b is a variable.
This can be expanded to 14*b
b. 30 is a coefficient, and j and k are variables.
This can be expanded to 30*j*k

Find the complete question
Zelie planned for a square pool to have a side length of 28 ft but found that it needs to be 14 ft long to fit in her backyard. She found the change of scale below.
Which is Zelie’s error?
Zelie should have divided both numbers by 14.
Zelie should have written the ratio as 28/7.
Zelie should have written the ratio as 14/8.
Zelie should have subtracted 14 from both numbers.
Original length of pool = 28ft
If he found that it need to be 14ft longer then the actual measure = 14th
given equation is;
(28 - 7)/14 - 7 = 14/7
Scale constant = original length/actual length
Scale constant = 28/14
Scale constant = 2
Hence the scale constant is 2
According to the option, Zelei should have divided both numbers by 14.
Answer:
Step-by-step explanation:
A circle is 360 degrees. What we are asked in words is, "How many degrees is 40% of 360?" Let x be "how many degrees"; the word "is" means =; 40% as a decimal is .4; the word of in this context means to multiply; and 360 is just 360. Putting all that together into an equation we can solve for x:
x = .4(360) so
x = 144
Adventure movies covers 144 degrees of that circle.
Answer: No. Kyle will arrive late
Step-by-step explanation:
The only speed limit is 50 miles per hour.
Kyle must cover 130 miles.
His travel time = 130/50 = 2.6
2 hours + (0.6 of 60 minutes )
2 hours + (36 minutes)
i.e kyle needs 2hours 36 minutes to cover 130 miles
And since the baseball starts in 2 hours, kyle will be late. Thus, the answer is No
What? You bought a call with options, and 50 lightning??
