Okay, I can’t really see all of the pictures completely but I’ll try my best to help.
For the page with the equivalent fractions, the answers are:
1/2 = 5/10
3/4 = 9/12
4/10 = 2/5
1/4 = 2/8
I would love to help more but I need more pictures to see the whole problem. I was going to try and help with the sequence problems but I can’t see it.
Anyways, I hope that this helps!
Answer:
14in approx
Step-by-step explanation:
Given data
number of rotations= 10
Distance travelled= 879.2 inches
Hence if in 10 rotations the distance covered is 879.2 inches
in 1 rotation the distance covered will be x inches
cross multiply
10x= 879.2
x= 879.2/10
x= 87.92 inches
This means that the circumference of the tire is 87.92 in
From
C= 2πr
Let us solve for r
87.92=2*3.142*r
87.92=6.284r
r= 87.92/6.284
r= 13.9
Hence the radius is 14in approx
1.0737408x10^9 is the answer in scientific notation
Given:
Length of cloth = 9 yards
Length of pieces = 
yards each
To find:
The number of pieces of cloths after cutting.
Solution:
Let n be the number of required pieces.
Length of each piece is yards. So, the length of n pieces is 
yards.
The length of the whole cloth is 9 yards. So, yards must be equal to 9 yards.
Multiply both sides by 3.
Therefore, the Greata have 27 pieces of cloths.
Remark
Are you sure you don't mean that (x - 7) is squared? The way you have written it indicates that it is squared. I'll treat it that way and you can leave a not if I am wrong.
Solution
(x - 7)^2 - 25 = 0 Add 25 to both sides
(x - 7)^2 - 25 + 25 = 25 Combine the left
(x - 7)^2 = 25 Take the square root of both sides.
sqrt(x - 7)^2 = sqrt(25)
x - 7 = +/- 5 Add 7 to both sides
x = 7 +/- 5
=========
x1 = 7 + 5
x1 = 12
x2 = 7 - 5
x2 = 2
Smallest x = 2
Largest x = 12
