The linear equation would be, 5d + 3h + 8s = 231
Answer:6+m+18
Step-by-step explanation: 6+m=7m so 7m+18 would be wrong. Hope it helps!
Answer:
10 DVD's were sold.
Step-by-step explanation:
c = number of CD's
d = number of DVD's
so we know:
c + d = 60
2*c/8 = d/2
this can be solved:
d = 60 - c
2c / 8 = (60-c)/2
4*(2c/8) = 4*(60-c)/2 [multiply by 4]
c = 120 - 2c
3c = 120
c = 40
d = 60-40 = 20
So Greg had 40 CD's and 20 DVD's. He sold half of his DVD's, i.e., 20/2=10 and 1/8 of his CD, i.e., 40/8 = 5
Answer: Morgan used aproximately 392.5 cm^3
To solve this, we calculate the voluime of the full can and then subtract the amount of broth remaining
Full can: we use the formula for the volume of a cillinder
Where r is the radius of the can and h the height. In this case, we use 17cm becouse the can is full
Remainning broth: again we use the volume of a cillinder, but in this case we use the height of the reamining broth (12 cm)
Now we do the full can minus the remaining broth:
And thats the amount of broth used
Answer:
3000
Step-by-step explanation:
There are 5 odd digits, so 5^3 = 125 ways to have 3 odd digits.
Given 3 odd digits, the first digit can be even, but not zero, so there are 4 ways to do that.
The second, third, or fourth digits can be even 5 ways, so there are ...
125(4 +5 +5 +5) = 2375
ways to have 3 odd digits in a 4-digit number.
__
There are 5^4 = 625 ways to have 4 odd digits.
The number of 4-digit numbers with 3 or 4 odd digits is ...
2375 +625 = 3000
