Answer:
cup of blueberries
Step-by-step explanation:
Since David starts out with 3 1/2 cups of blueberries and uses 1/4 cup to make a smoothie, we will need to subtract 1/4 from his starting amount of 3 1/2
David now has 3 1/4 cup of blueberries
David then uses half of this new amount of blueberries to make his pancakes. We will need to divide by 2 in order to figure out how much half is
- First we can turn 3 1/4 into an improper fraction to make it easier to work with → 3 1/4 = 13/4
- Now dividing 13/4 by 2 gives us
- David used 13/8 cups of blueberries to make his pancakes
- Turning this back into a mixed number leaves him with 1 5/8 cup of blueberries
You can use number patterns to find the LCM of 120 and 360 by multiplying 120 by 1,2,3,4,5,6,and so on and do the same with 360 until you find the least number that they have in common.

Step-by-step explanation:
Answer:
x=2,y=-6,z=-1
Step-by-step explanation:
Hello, I think I can help you
Let
equation 1 (1) 4x-16z=24
equation 2 (2) 2x-3y-3z=25
equation 3 (3) 2x+2y-3z=-5
equation 4 (4) 4x+2y+2z=-6
to eliminate x and z , we can do
(2)-(3)
2x-3y-3z=25
-(2x+2y-3z=-5)
____________
0-5y-0 =30
-5y=30
divide each side by -5
-5y/-5=30/-5
y=-6
to eliminate y , we can do
(3)-(4)
2x+2y-3z=-5
-(4x+2y+2z=-6)
___________
-2x+0-5z=1 equation (5)
Now, to eliminate z do, (1)+2*(5)
(1) 4x-16z=24
2*(5)=-4x-10z=2
(1)+2*(5)
4x-16z=24
-4x-10z=2
_________
0-26z=26
-26z=26
z=26/-26
z=-1
from (1) isolating x
4x-16z=24
4x=24+16z
x=6+4z
x=6+4(-1)
X=2
have a great day
