Answer:
B. 3 pages are edited every five minutes
D. 6/10 of a page is edited per minute
Step by step:
Three pages are done at an interval of five minutes.
Six tenths of a page is done every minute
0.6 * 5 = 3 per five minutes
The other statements are false.
12/3 = 4, four done every minute, really?
5 pages are edited every three minutes.
This would disprove statement B.
And does not align with the graph.
Hope this helps.
Answer:
paper clips = $1.85
index cards = $3.95
Step-by-step explanation:
Mark
12 paper clips = x
10 index cards = y
$61.70 total
Janice
15 paper clips = x
7 index cards = y
$55.40 total
12x + 10y = 61.70
15x + 7y = 55.40
*** you want to cancel out one of the letters
(12x + 10y = 61.70) * -7
(15x + 7y = 55.40) * 10
-84x -70y = -431.9
150x + 70y = 554.0
150x + 70y = 554.0
-84x -70y = -431.9
66x + 0 = 122.1
66x = 122.1
x = 122.1 ÷ 66
x = 1.85
plug it back in
15(1.85) + 7y = 55.40
27.75 + 7y = 55.40
7y = 55.40 - 27.75
7y = 27.65
y = 27.65 ÷ 7
y = 3.95
