Answer:
The black-and white printer print can print 15 pages per minute.
Step-by-step explanation:
The given modeled equations are
3b + 5c = 70...(i)
6b + 9c = 135...(ii)
where b is the number of pages per minute of the black-and-white printer and c is the number of pages per minute of the color printer.
From equation (i), we have
Now, substitute the value of b in equation (ii), we have
By using equation (iii), we have
Hence, the black-and white printer print can print 15 pages per minute.
Answer: see below
<u>Step-by-step explanation:</u>
Input x = 13, y = 84, r = 85 into the trig functions:
Answer:
5.7 + 2.5/10x ≥ 8
where x is the artistic score
Step-by-step explanation:
if the technical score is 7.6/10 = 76% of 75% = 0.57 out of 10.
there are still 2.5 more points that can be obtained, so the gymnast needs 8 - 5.7 = 2.3 out of 2.5 possible points
the inequality would be:
5.7 + 2.5/10x ≥ 8
where x is the artistic score
2.5/10x ≥ 8 - 5.7
2.5/10x ≥ 2.3
x ≥ (2.3 x 10) / 2.5
x ≥ 9.2
Negative 34 means (-34)
times means to multiply, then
To do it without a calculator we will make -34
-30 + -4, then multiply -30 by 1567 and multiply -4 by 1567 then add the two answers
Then add the answers
The answer is -53278
