6r+70=-2(35+3r)
multiply the bracket by -2
(-2)(35)=-70
(-2)(3r)=-6r
6r+70=-70-6r
move -70 to the left side
sign changes from -70 to +70
6r+70-70=-70-70-6r
6r=-70-70-6r
move-6r to the left side
6r=-140-6r
move -6r to the other side
6r+6r=-140-6r+6r
12r=-140
divide both sides by 12
12r/12=-140/12
r=-140/12
reduce- by dividing by 4
-140/4=-35
12/4=3
Answer:
r= -35/3 and r=-11 2/3
First you need to set this problem up as a cross multiply fraction set (actually forgot the name of it so I described it as that).
10/15 * 30/x
Solve for X
450 = 10x
Simplify
45 = x
The Daily dose is 30 meq/45 ml. For a 30 day supply you just multiply by 30.
1350 ml is needed for a 30 day supply.
Two thirds can equal: 4/6, 6/9, 8/12, 10/15, etc.
Answer:
5/6
Step-by-step explanation:
1/3 x 2/2 = 2/6
1/2 x 3/3 = 3/6
2/6 + 3/6 = 5/6
1. Shifts up 9
2. Shifts down 2
3. Reflect over x-axis and shifts left 5
4. Shifts right 4 and down 1
5. Vertical compression of 1/3 and shifts up 2
6. Reflect over x-axis, vertical stretch of 2, and shifts left 4
7. f(x)=-(x-3)^2+7
