Answer:
40% of 25 is 10
Step-by-step explanation:
-2(z+3)-z=-z-4(z+2)
solve for z quickly please! will give brainliest
Answer:
[tex] \sf z = - \dfrac{2}{3} [/tex]
Step-by-step explanation:
Solve for z:
[tex] \longrightarrow [/tex] -2(z + 3) = -z - 4(z + 2)
-4(z + 2) = -4z - 8:
[tex] \longrightarrow [/tex] -2(z + 3) = -z -4z - 8
Grouping like terms, -z - 4z - 8 = (-z - 4z) - 8:
[tex] \longrightarrow [/tex] -2(z + 3) = (-z - 4z) - 8
-z - 4z = -5z:
[tex] \longrightarrow [/tex] -2 (z + 3) = -5z - 8
Expand out terms of the left hand side:
[tex] \longrightarrow [/tex] -2z - 6 = -5 z - 8
Add 5z to both sides:
[tex] \longrightarrow [/tex] (5z - 2z) - 6 = (5z - 5z) - 8
5z - 5z = 0:
[tex] \longrightarrow [/tex] (5z - 2z) - 6 = -8
5z - 2z = 3z:
[tex] \longrightarrow [/tex] 3z - 6 = -8
Add 6 to both sides:
[tex] \longrightarrow [/tex] 3z + (6 - 6) = 6 - 8
6 - 6 = 0:
[tex] \longrightarrow [/tex] 3z = 6 - 8
6 - 8 = -2:
[tex] \longrightarrow [/tex] 3z = -2
Divide both sides of 3z = -2 by 3:
[tex] \longrightarrow [/tex] [tex] \sf \dfrac{3}{3}z = - \dfrac{2}{3} [/tex]
[tex] \sf \dfrac{3}{3} = 1 :[/tex]
[tex] \longrightarrow [/tex] [tex] \sf z = - \dfrac{2}{3} [/tex]
Suppose a, b, and c are all negative numbers. How do you find the distance between the points (a,b) and (a,c)?
Choose the correct answer below.
A. Subtract the lesser of |b| and |c| from the greater.
B. Subtract the greater of |b| and |c| from the lesser.
C. Add to |c|.
D. Subtract |b| from |c|.
E. Subtract |c| from |b|.
Answer:
E
Step-by-step explanation:
Let's say if b = -2 and c = -3
-2-(-3) = 1 that would be the distance between them. If it was D then you would need absolute value.

Solve the equation for x.
One-third (6 x minus 15) = one-half (10 x minus 4)
a.
-10
c.
StartFraction 1 Over 10 EndFraction
b.
1
d.
-1
Answer:
X= -1
Step-by-step explanation:
[tex](\frac{1}{3} )(6x)+(\frac{1}{3} )(-15)=(\frac{1}{2} )(10x)+(\frac{1}{2} )(-4)[/tex]
(Distribute)
2x+−5=5x+−2
2x−5=5x−2
Step 2: Subtract 5x from both sides.
2x−5−5x=5x−2−5x
−3x−5=−2
Step 3: Add 5 to both sides.
−3x−5+5=−2+5
−3x=3
Step 4: Divide both sides by -3.
Which = -1
Hope this helps :)

Answer:
26 busses.
Step-by-step explanation:
the first 25 busses will be full. then the last one will have 6 people.
I'LL GIVE YOU 20 POINTS AND BRAINLIEST!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
I can see how this is confusing, because of -2, but the slope is decreasing, so the question wouldn't say:
[tex]-3/5x - -2[/tex]
This happens to turn the -2 into a regular 2 with an addition (+) sign.
and since the graph has an input of 5 but an output of -3, the equation would be:
y = -3/5x + 2
