Answer: the system of equations are
x + y = 22
x + 1.5y = 30
Step-by-step explanation:
Let x represent the number of math problems that Olivia solved.
Let y represent the number of pages that Olivia read.
Olivia completed a total of 22 math problems and pages of reading. This means that
x + y = 22- - - - - - - - - - - - - - -1
Olivia can solve each math problem in 1 minute and she can read each page in 1.5 minutes. Olivia completed a total of 22 math problems and pages of reading in 30 minutes. This means that
x + 1.5y = 30 - -- - - - - - - - - -2
Answer:
360:480
We know the total (840) so add the ratio: 3 + 4 =7
Divide 840 by 7 = 120
Multiply each part of the ratio by 120
3 x 120 = 360
4 x 120 = 480
Step-by-step explanation:
The answer would be y=42x
