I see you need help with 14 - 23 evens, so hopefully this is what you need. If not, comment and I will edit it as appropriate :) Have a nice day
14: It is slightly hard to see, but I am going to say 15 mm. We can decide this because the ruler says it is in mm and on both sides are 10 and 20. It is in the middle so we will decide the answer is 15.
16: 3,629 - 429 = 3,198 (not much explanation, just use a calculator or do the subtractation)
18: 491 * 700 = 343,700 (multiply 491 * 7, then add the two zeros onto the end of the answer because it's 700, not 7)
20: 5n = 3,175 ; n = 635 (divide both sides of the equation by 5)
22: See pictured below
After that, 2/3 is equal to 0.66666666666, which we can round to 67%
Even though it is not an even, you said "14 - 23" so here is 23 as well:
230, 240, 250, 260, 270, etc

Answers
Answer:
26.5 miles.
Step-by-step explanation:
Given: Time for running Boston Marathon= 2.12 h
Speed= 12.5 mph
Distance covered in Boston Marathon
Distance covered= speed x time
Distance covered = 12.5 x 2.12=26.5 miles
∴ Distance covered in the Boston Marathon is 26.5 miles.
Answer:
26.5

In a high school basketball game, a player on the home team makes two free throws. One student asks the student next to her what he thinks the probability of hitting two free throws in a row is. The student replies, "The probability of him making a free throw is probably about .6, so hitting two free throws is probably about 1.2." Why can this immediately be dismissed as incorrect?
A.
The final number, 1.2, is a fraction, which can never represent a probability.
B.
The probability of making a free throw can never be .6.
C.
The probability of an event happening twice in a row can never be equal.

Find the missing side of each triangle. Round your answers to the nearest tenth if necessary. (Please Show your work)
Answers
Answer:
12.2 mi
Step-by-step explanation:
We need to use the Pythagorean theorem, we can use the equation A^2 + B^2 = C^2 then get the square root of the answer
plugging in the numbers with the equation we get the equation:
10.6^2 + 6.1^2 = c^2
then we multiple the available numbers by their exponents we get:
112.36 + 37.21 = c^2
Adding the numbers together we get:
112.36 + 37.21 = 149.57
Get the square root of 149.57 (Since the earlier equation was just everything squared) we get:
12.2298814385
Round it to the nearest tenth as directed, then we get:
12.2
The answer is 12.2 mi

What is the solution to the system of linear equations? 2x + 3y = 3 3x + 5y = 5 Enter you answer into the boxes.
Answers
Answer:
x = 0
y = 1
Step-by-step explanation:
2x + 3y = 3 Multiply this equation by 3
3x + 5y = 5 Multiply this equation by 2
3(2x + 3y = 3)
6x + 9y = 9
2(3x + 5y = 5 )
6x + 10y = 10 Notice the xs are the same.
6x + 9y = 9
6x + 10y =10 Subtract
- y = - 1 Multiply each side by -1
y = 1
2x + 3y = 3
2x + 3*1 = 3
2x = 0
x =0
