Answer:
m= (110 - 2(20)) / w
m= typical amount of money saved each week
w= amount of weeks in this time period
Step-by-step explanation:
you would take the $110 he had saved up and subtract the additional $20 from the past 2 weeks which would be $40 or 2 times 20, and then you would take that total amount, which is why it is in parentheses, and divide it by the number of weeks that Matthew had been saving for that time period where he saved $110.
For example:
If Matthew had been saving for 5 weeks what you would do is,
m= (110 - 2(20)) / w
m= (110 - 2(20)) / 5
m= (110 - 40) / 5
m= (70) / 5
m= 14
therefore if Matthew had been saving for 5 weeks typically he would have saved $14 every week
(keep in mind this is only if he had been saving for 5 weeks if he had been saving for any other number of weeks the answer would be different)

8x-10=3x+90
8x-3x= 90+10
5x=100 divide by 5x on each side
X=20
B=3(20)+90= 150
Answers: X=20
Angel B is 150°

<u>In a 30-60-90 triangle, the shorter leg is always 1/2 of the hypotenuse.</u> This can be proven using many different methods and there a lot of interesting videos out there about it. This is useful in geometry, trigonometry, and more.
So, if we know that the shortest leg is 12, we can make the following equation. We will have h represent the hypotenuse.
1/2h=12
Now, we simply divide both sides by 1/2 (which is the same as multiplying both sides by two.
h=24
Therefore, the hypotenuse is C) 24.
I hope that this helps! Have a wonderful day!
