Answer:
328 pages for the novel
123 pages for the second day
Step-by-step explanation:
Let the number of pages of the novel = x
Raw Equation
(1/4)x + 1/2 (3/4)x + 123 = x
Solution
(1/4)x + (3/8)x+ 123 = x
Change the fractions to common denominators.
(2/8)x + (3/8)x + 123 = x
Add the fractions.
(2/8 + 3/8)x + 123 = x
Subtract (5/8)x from both sides.
(5/8)x + 123 = x
(5/8)x- (5/8)x + 123 = x - (5/8)x
Multiply both sides by 8
123 = (3/8)x
123 * 8 = 3x
Divide by 3
984 = 3x
984/3 = 3x / 3
328 = x
===================
At the end of the second day, she read 3/8 * 328 = 123 pages.
Answer:
Using the form y = m x + b where b is the y-intercept and m the slop
1. 6.85 is the y-intercept- when c = 0 the value of y will be 6.85
2. the slope here is m = 2.95 that means for every increase of 1 on the x-axis which is c the value of y increases by 2.95 (additional cost of each child)
3. If no children were to go the cost would be 6.85 (c = zero)
So she paid 18.65 - 6.85 = 11.8 for the children that went
11.8 / 2.95 = 4 so 4 of her grandchildren attended

Answer:
4x+7=27
Step-by-step explanation: The answer you think is correct ! So the 4 times a number is 4x the four being a coefficient and X being the unknown number( variable ) and increase is adding so its +7 and is is just an another word for equal =
