Answer:
model a: 9 presses
model b: 9 presses
Step-by-step explanation:
let x=model a and y=model b.
If asanji has 28 printing presses, we can say that x+y=18.
If he can print 1260 books in a day, we can say that 80x+60y=1260.
Now, We can solve the system of equation by solving an equation in terms of any variable. You can choose any variable. I chose x. x+y=18, So if we subract y from each side, we get x=18-y. Now, we can substitute that in the other equation. Thus, 80(18-y) +60y=1260. If we continue to solve for y, 1440-80y+60y=1260, 1440-20y=1260, subtract 1440 from each side, which gives you -20y=-180, and divide - 20 and you get y=9. Now, substitute the 9 in the x+y=18 to find x. Thus, x+9=18, and x=9. So, Asanji has 9 press of Model A and 9 presses of Model B.
Answer:
The vertical angles are
< 8 and < 5
Step-by-step explanation:
64 pages
divide 40 by 5 for pages printed in 1 minute then multiply this by 8
× 8 = 8 × 8 = 64 pages
Range: your highest and lowest number and subtract........91-36 = 55
Mode: is the number that shows up the Most Often..... you don't have one in this.
Median: put all your numbers from least to greatest and cross of one number at a time at each end if you come to 2 numbers in the middle add them up and divide them by 2....... 48+67=115...115/ 2 =57.5
Mean; Add all the numbers up and divide them by how many numbers are there.....36+48+67+91=242...242/ 4 =60.5
