Answer:
On day 20, they should both be on page 200
Step-by-step explanation:
I set the 2 equations up:
10d=8d+40 and then subtracted 8d from both sides
2d=40 and then divided both sides by 2
d=20
I then took 20 and multiplied it by 10 for Ashley (200) and then multiplied it by 8 for Carly (160) and added 40 (200)
Hope this helps!

The data we have are;
Difference between the numbers are 12.
3 times larger number is equal to 7 times smaller number.
Then we can write;
 ----(1)
 ----(2)
From (1) we can say 
Then substituting  to (2) gives;




Then;

Answer:
18 and 6
Step-by-step explanation:
Rn = 6 Ratio numerator
Rd = 2 Ratio Denominator
Rs = Rn + Rd
Rs = 6 + 2
Rs = 8
Ratio Sum
a = 24 Amount to Divide
M = a ÷ Rs
M = 24 ÷ 8
M = 3 Multiplier Ratio Division Calculation
Rr = Rn × M : Rd × M
Rr = 6 × 3 : 2 × 3
Rr = 18 : 6
So first remember the order of operations. Parentheses, exponents, multiply, divide, addition, subtraction.
So we have the following problem.
-(3*2)2+4*3-2
Multiply the three and two inside the parentheses first.
-6*2+4*3-2
Next multiply any numbers that need multiplied.
-12+12-2
Next add and subtract from left to right to get an answer of...
-2
Hope this helps!
