1.Two cyclists are 7 miles apart when they begin biking away from each other in opposite directions. The speed of the first cyclist is 12 miles per hour. The speed of the second cyclist is b miles per hour greater than the speed of the first cyclist.
How many miles does the first cyclist bike in 45 minutes?
Answer:
9 miles
Step-by-step explanation:
If 1 hour is 12 miles, then 30 mins is 6 miles, then 15 minutes is 3 miles.
30+15=45
6+3=9
The first cyclist bikes 9 miles in 45 minutes.
Since two cyclists are 7 miles apart when they begin biking away from each other in opposite directions, and the speed of the first cyclist is 12 miles per hour, to determine how many miles does the first cyclist bike in 45 minutes the following calculation must be done:
60 = 12 45 = X 45 x 12/60 = X 540/60 = X 9 = X
Therefore, the first cyclist bikes 9 miles in 45 minutes.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
5x - 2w + t = 0
Solve for x.
5x - 2w + t = 0
5x = 2w - t
x = (2w - t)/5
Solve for w.
5x - 2w + t = 0
5x + t = 2w
w = (5x + t)/2
Solve for t.
5x - 2w + t = 0
t = 2w - 5x
Thus,
The value of x, w, and t is given above.

It takes Austin 8 hours longer than Elliott to construct a wooden chair in shop class. When the classmates work together, they can complete one chair in 3 hours. This situation can be represented by this expression, where t is the amount of time, in hours, it takes Elliott to complete a chair on his own.
The equivalent expression obtained using the least common multiple concept is [tex] \frac{6t + 24}{t^{2} +8}[/tex]
To solve, we need to obtain the L. C. M of the denominator values :
The L. C. M of t and t + 8 = [tex] t^{2} + 8t[/tex]
Hence,
[tex]\frac{3}{t} + \frac{3}{t+8} = \frac{6t + 24}{t^{2} +8}[/tex]

explain why 3(5x) does not equal to (3 times 5)(3times x)
Answer:
Because 3(5x) is the same as 3 *5 * x
Step-by-step explanation:
When a number is next to another in parantheses, it signifies multiplication. In this case, we already have 5 and x grouped together by a multiplication sign, so the entire thing is 5 * x. The statement below is key
Distribution in multiplication is only possible if a variable is grouped to another real number by a plus or minus sign.
So in this case, we have 3 * 5 * x, which is 15x. However, if we had 3(5 + x), we would have 15 (3 * 5) + 3x (3 * x).
Hopefully that makes sense!

Answer:
PQ=30
Step-by-step explanation:
Knowing that the segment has 3 parts that are 3:1:1 and sum up to 50, you could find how much 1 would equal by finding the total in relation to the ratio (doing 3+1+1) which gets you 5 parts. Then you can divide the total (50) by 5 to figure out how much one part would equal (10). Now, since you know that 1 part is equal to 10 and that PQ is 3 parts, you can find that PQ is equal to 3x10, or 30.

2. Sarah has some blue marbles, twice as many red marbles as blue, and 8 yellow marbles. If she has a total of 32 marbles, how
many red marbles does she have?
A.8
B.12
C.16
D.24
Given:
Number of blue marbles, twice as many red marbles as blue, and 8 yellow marbles.
She has a total of 32 marbles.
To find:
The number of red marbles.
Solution:
Let number of blue marbles be x.
Then, number of red marbles = 2x
Number of yellow marbles = 8
Total number of marbles = 32
[tex]x+2x+8=32[/tex]
[tex]3x=32-8[/tex]
[tex]3x=24[/tex]
[tex]x=8[/tex]
Now,
Number of red marbles [tex]=2(8)=16[/tex]
Therefore, there are 16 red marbles.

Which group of ordered pairs are on the line given by the equation 5x−2y=6?
Answer:
(0, -3), (2, 2), (4,7) these are just some points
Step-by-step explanation:
Put the equation in y=mx+b format. It will be 2y=5x-6.
y=5/2x -3
the first point will be (0, -3) because of the y-intercept which is negative 3. You can graph the slope from that point to get (2, 2) and (4, 7). You can get more points too
Answer:
There are infinite ordered pairs are on the line because it has infinite solutions.
Step-by-step explanation:
5x - 2y = 6
-5x -5x
-2y = -5x + 6
-2y/2 = -5x/-2 + 6/-2
y = 5/2x - 3
5x - 2(5/2x - 3) = 6
5x - 5x + 6 = 6
6 = 6
