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.

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!

Jaxon was asked 40 questions on a test he answered 80% incorrectly how many did he get correct
Answer:
8 correct.
Step-by-step explanation:
80 / 100 = x / 40 (Since he got 80% INCORRECT you will subtract the value of x from 40)
100x = 80 x 40
x = 3200 / 100
x = 32
40 - 32 = 8
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.

help me solve this
marked as brainless if correct
Answer:
Use synthetic division to solve
Step-by-step explanation:
When dividing a polynomial by a zero, you first want to find the zero to divide by. Solving the zero (x+2) will give us the value of x to divide by. Subtracting 2 from each side gives us x=-2. Then, we write out the full polynomial. Since the only degrees that have numerical values are x^5 and 32, we substitute zero for the values in between (0x^4, 0x^3, 0x^2, and 0x). Then we follow the steps of synthetic division (as seen in the photo) to find our new values for our new equation.

what is exterior angle property?If a side of a triangle is produced, then the exterior angle so formed is equal to the sum of the two interior opposite angles.
Given:
<1 = x
<2 = 24
exterior angle = 105
Now, using exterior angle property
105 = x +24
x= 105 - 24
x= 81
Hence, the value of x is 81

When = 3, what will the value for y be for the equation - 4x + 5y = 18?
If x equals 3 then y must equal 1.2
Answer: y=6
-4(3)+5y=18
-12+5y=18
add 12 to both sides
-12+5y+12=18+12
5y=18+12
5y=30
divide both sides by 5
5y÷5=30÷5
y=30÷5
y=6

Diego measured the length of a pen to be 22 cm. The actual length of the pen is 23 cm. Which of these is closest to the percent error for Diego’s measurement. Explain your choice. [3 point]
4.3%
4.5%
95.7%
104.5%
Answer: its either a or b
Error is the difference between the actual length of an object and its measured length.
The closest to the percent error for Diego's measurement is 4.3%
Step 1: Find the error
Error = Actual length - Measured length
= 23cm - 22cm
= 1 cm
Step 2: Find the percent error
Formula = Error/ Actual length × 100
= 1 /23 × 10
= 4.35%
Therefore, the closest to the percent error for Diego's measurement is 4.3%
