Answer:
$10 coins: 21
$20 coins: 24
Step-by-step explanation:
heyy me again
So we can create 2 equations where
x = number of $10 coins
y = number of $20 coins:
x + y = 45
10x + 20y = 690
we can move equation 1 around so that we can get a value of x
x = 45 - y
now we can substitute x into the second equation
10(45 - y) + 20y = 690
450 - 10y + 20y = 690
10y = 240
y = 24
Now plug in y back into the first equation
x = 45 - y
x = 45 - 24
x = 21
15x-24
the answer is not B because 3*-5= -15, we need -24
the answer is not C because 3*-24= -72
the answer is not A because 5*8= 40
Answer :
D. 3(5x − 8)
(3)(5x)(3)(-8)
15x-24= 15x-24
Answer:
A
Step-by-step explanation:
Answer:
green triangle
Step-by-step explanation:
The green triangle has an area of
A = 1/2 bh
A = 1/2 (15) * 19
A =142.5 ft^2
The blue triangle has an area of
A = 1/2 bh
A = 1/2(16.1) (16.4)
A =132.02 ft^2
The green triangle has a greater area
1-My data set is 2,2,4,6,8,8,6,1,3,3,5,6,11
2- I made up my own data set
3- The Mean of my data set is 5
4- The median is also 5
5- The first quartile is 2.5
6- The third quartile is 7
7- the inter quartile range is 4.5
8- the inter quartiel range is 4.5 because; to solve inter quartile range it is the differnece of the 75% quartile and the 25th percent quartile so the 25th percent quartile is 2.5 and the third quartile is 7. 7-2.5 is 4.5
9- The Mean Absuloute Deviation (MAD) is 2.3076923076923
Rounded to 2.3
10- The mean absolute deviation is the mean of the data absolute deviation in this case the absolute distance from the mean is the simplified definition which would be 2.3
