Answer:
10v^2
Step-by-step explanation:
(I'm assuming the 2's are all exponents)
3v^2 - 2v^2 + 9v^2 <- think of it as 3 - 2 + 9 = 10, then add the rest back on
10v^2
So, let's set this up:
0.04x+0.05y=1100
0.05x+0.04y=1150
Let's multiply each equation by 100:
4x+5y=110000
5x+4y=115000
Now let's add those together:
9x+9y=225000
And we need to find x+y, so we just divide by 9 and get 25,000
Answer:
6:10pm
Step-by-step explanation:
At 6:00 the hands are 180° apart.
The hour hand moves 1/12 of circle per hour = 30° per hour = 0.5° per minute.
The minute hand moves 1/60 of the circle per minute = 6° per minute
Angle between the hands decreases by 6-0.5 = 5.5° per minute.
180 - 5.5t = 125
t = 125/5.5 = 10 minutes
The hands are 125° apart at t minutes after 6:00, or 6:10.
Answer:
B) y+3=-1/4(x-8) hope this helps! :D
Step-by-step explanation:
point-slope formula is y-y1=m(x-x1)
y1 and x1 are coordinates, aka a point
s>7
So, all values greater than 7 are included in the number line.
Step-by-step explanation:
We need to use number line to show numbers in the solution set of the inequality 2s+ 36 greater than 50
Solving and finding value of s:
2s+36>50
Adding -36 on both sides
2s+36-36>50-36
2s>14
Divide both sides by 2
s>7
So, all values greater than 7 are included in the number line.
The number line is shown in figure attached below
