Answer:
A.
B.
Step-by-step explanation:
We have been given that there are five coins in Dan's bank. Some are dimes and some are nickels.
A. To find greatest amount of money that Dan could have, we will assume that there are 4 dimes and 1 nickel.
We know that 1 dime is worth 10 cents or $0.10 and 1 nickel is worth 5 cents or $0.05.
Value of 4 dimes would be
Therefore, the greatest amount of money that Dan could have, is $0.45.
B. To find least amount of money that Dan could have, we will assume that there are 4 nickels and 1 dime.
Value of 4 nickels would be
Therefore, the least amount of money that Dan could have, is $0.30.

Hello I Just had this problem. The answer IS A
Step-by-step explanation:
<u>Answer:</u>
9. x = 12
10. x = 31
<u>Step-by-step explanation:</u>
9. Corresponding angles are equal, so technically you can move that (7x - 20) to be diagonal with the (4x + 16). Along with the corresponding angle, diagonal angles are equal to each other. Therefore you can set (7x - 20) equal to (4x + 16) to find x.
7x - 20 = 4x + 16
Solve
3x - 20 = 16
3x = 36
x = 12
Therefore x is equal to 12
<u>Check:</u>
4(12) + 16
= 64
7(12) - 20
= 64
10. All angles in a triangle have to add up to 180 degrees. Therefore, you can write your equation like this:
x + 2x + 25 + 2x = 180
Combine like terms
5x + 25 = 180
Solve
5x = 155
x = 31
Therefore, x = 31.
<u>Check:</u>
31 + 2(31) + 25 + 2(31) = 180
31 + 62 + 25 + 62 = 180
180 = 180

Answer:
R=(-1,2), T=(-7,4) S=(-2,8)
Step-by-step explanation:
The line y=x is a diagonal line veering to the left, since I can't draw it I'll give you a link on an actual digram of a triangle getting reflect across y=x. But, I just like to do this, if for example Q=(10,-3), I just exhange the negative sign to the left, so it would equal Q"=(-10,3) (Q" means the new modified Q).
