I only know (b) and 28 (c)
(b) Multiples of 120= 120,240,360,480,600
Multiples of 150= 150,300,450,600
Both numbers have 600 as their first common multiple so the ANSWER is 600
28. (a) Common factors of 24= 1,2,3,4,6,8,12,24
Common factors of 64= 1,2,4,8,16,32,64
8 is the only common factor for both 24 and 64 so 8 is the ANSWER
Answer:
2.25 cups
Step-by-step explanation:
15.75÷7= 2.25 cups of flour for one batch of cookie
Create a system of equations
x + y = 123
5x + y = 343
I use substitution
y = 123 - x
5x + 123 - x = 343
4x + 123 = 343
4x = 220
x = 55
Plug in
x + y = 123
55 + y = 123
y = 68
Check
5x + y = 343
5(55) + 68 = 343
275 + 68 = 343
343 = 343
A midsegment is given by the formula:

Where x1, x2, y1, and y2 correspond to their respective coordinates. We can do the equation:

This gets us a midpoint coordinate of <span>
(1,1)</span>As for distance, it will be found by doing:

We can do the following:



This simplifies to

:)
To find the number of words she can read per minute, we would do 560 divide by 7 minutes
560/7 = 80 words per minute
Hope this helps
