Which equation has a solution of x=8.5?


A −5x=42.5negative 5 x is equal to 42 point 5

B −3x=−25.5negative 3 x is equal to negative 25 point 5

C x−3.5=12x minus 3 point 5 is equal to 12

D x+2.5=−11
Pls Help!!

Answer:

A: $2,600

Step-by-step explanation:

0.15m = 390

Isolate the variable m by diving both sides by 0.15

0.15m ÷ 0.15 = 390 ÷ 0.15

m = 2600

a. 13

first I subtracted 323 and 149.5 to get 173.5 I did this beacause you want to find out how much is left, then I divided 173.5 by 13 and got 13.

Answer:

A. 13 people

Step-by-step explanation:

The equation is 13x + 149.50 ≤ 323

Step 1: Subtract 149.50 from both sides.

13x + 149.5 − 149.5 ≤ 323 − 149.5

13x ≤ 173.5

Step 2: Divide both sides by 13

13x/13 ≤ 173.5/13

x<13.346154

Since you cant have 13.34 of a person you have to round to 13

So, the greatest number of people Justin can allow to attend the workshop is 13 people

Answer:

A: rising (angle, up)

B: steady at high (horizontal)

C: falling (angle, down)

D: steady at bottom (horizontal)

Step-by-step explanation:

as the bus starts moving and increases speed over time, the line rises, showing how the bus is gaining speed over the course of 1 min

then the stayed at the higher speed wile it traveled for x amount of time to get to the destination, so the line stayed steady as well

as it started to slow down, the speed decreased, and so does the line on the graph, this goes on for one more minute

then the bus stops to let off the passengers, it stays at 0mph for 2 mins, so the line rests at 0 for two mins on the line

note: at NO POINT should the line be vertical, else it would NOT be a function, the bus takes time to accelerate and decelerate, if the line between transitions were vertical the bus would go from 30 mph to 0 in no time, no literally, at that point you would have multiple x values for 1 y value, both the top of the line at 30mph, the bottom of the line at 0 and ALL the speeds in between, so VERTICAL LINES SHOULD NOT BE USED

hope this helps

You know it's not A because there is more than 7 hundreds

It's also not C because it would have to be 7 ones, not 7 tens

Answer:

8:05 pm (If you round to the nearest tenth place)

Step-by-step explanation:

basically, 4:00 pm and 5:10 pm have a 1 hour and 10 minute difference.

1 hour and 10 minutes divided by 65 miles is 1.6923076 or 1.7 minutes

1.7 minutes times 150 miles is 2 hours and 55 minuets

2 hours and 55 minutes plus 5:10pm is 8:05 pm

I'm so sorry if I'm wrong!

Answer: a) d(t) = [tex]\frac{13}{14}[/tex] (t - 70) + 65   b: 6:41 pm

duration of time passed:

5:10 pm - 4:00 pm = 70 mins

distance = 65 miles

you points to use to make an equation:

(0,0) and (70,65)  ---------------------> ( (0,0) is bc youre beginning the trip and you have no distance )

find the slope of your "future" equation

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{65}{70}[/tex] = [tex]\frac{13}{14}[/tex] = m

now use point-slope form

y - 65 =  [tex]\frac{13}{14}[/tex] (x - 70)

y=  [tex]\frac{13}{14}[/tex] (x - 70) + 65

and since it wants it in terms of d and t,

d(t) = [tex]\frac{13}{14}[/tex] (t - 70) + 65

part b:

150 =  [tex]\frac{13}{14}[/tex] (t - 70) + 65

85 = [tex]\frac{13}{14}[/tex] (t - 70)

85 = [tex]\frac{13}{14}[/tex] t - 65

150 = [tex]\frac{13}{14}[/tex] t

2100 = 13t

161.54 = t

about 162 minutes

Thennnn:

162/60 = 2 hours and 41 mins

4:00 pm + 2 hours and 41 mins = 6:41 pm

Answer:

19
