Answer:
x = 23.5
Step-by-step explanation:
For a trapezoid, the angles on the same side are supplementary. This simply mean they add up to 180 degrees
thus, we have it that;
(6x + 3) + (x + 12.5) = 180
6x + x + 3 + 12.5 = 180
7x + 15.5 = 180
7x = 180-15.5
7x = 164.5
x = 164.5/7
x = 23.5

Answer:
y = x - 10
Step-by-step explanation:
10 less than a number is the same as 10 subtracted from the number.
If you start with 30, 10 less than 30 is the same as 10 subtracted from 30.
30 - 10 = 20. The input is 30, and the output is 20, which is 10 less than 30.
If you start with x, 10 less than x is the same as 10 subtracted from x, or x - 10. The input is x. Subtract 10 from the input, or x - 10. The output equals x - 10.
y = x - 10
See how many times the denominator goes into the numerator. For example, with 24/8, 8 goes into 24 three times, so 24/8 is 3. If I had 25/8, then it would be 3 1/8 because you have one left over after you divide the 8 into 25.
Answer:
Krutika
Step-by-step explanation:
Lets convert each person's typing rate to words/min.
Krutika:
80 minutes = 6000 words
1 minute = (6000/80) words
= 75 words
Typing Rate: 75 words / min
Mark:
60 minutes = 4200 words
1 minute = (4200/60) words
= 70 words
Typing Rate: 70 words / min
David:
90 minutes = 5850 words
1 minute = (5850/90) words
= 65 words
Typing Rate: 65 words / min
From the above, we can see Krutika has the fastest rate of words per minute.
