Answer:
The distance between the two cities is 360 miles.
Step-by-step explanation:
Let a equal the airspeed of the plane in still air; and d be the distance between the two cities. Then:
d/a+30=1.5
d=1.5a+45
and
d/a-30=2
d=2a-60
So
2a-60=1.5a+45
.5a=105
a=210
d/210-30=2
d=360
The distance between the two cities is 360 miles.

-5= -10+y how do i reorder this and why do i reorder it in that way? i think i know how to reorder it i'm just confused on why it has to be ordered that way. plz help, thanks!
Answer:
y = 5
Step-by-step explanation:
Ok so you need to move y to its own spot so either on the right or left of the equation. BUT i recommend leaving it and instead moving -10 to the other side. REMEMBER when you move a number to the other side of the equation you change its value so instead of -10 it will become +10. so you will get 10-5=y so 5=y, if you want the y to be on the other side flip them around -y=-5(since you switched them you need to make them minus, or plus if the number was originally negative) SINCE you have minuses on both sides you can cancel them out and you will be left with y=5.
Why you need to reorder:
you need to reorder to find Y there is no way you can find Y without reordering. When you are reordering remember that Y has to be by itself in one side of the equation.

Meghan's home is on the same straight road as the library and sporting goods store. Meghan marks the location of the library and the location of the sporting goods store on a number line, using her home's location as 0. She marks the library at −3.7 and the sporting goods store at 12.5. What is the distance between the library and the sporting goods store on Meghan's number line? Enter your answer as a decimal in the box.
Answer:
Step-by-step explanation:
-3.7+12.5=8.8
Answer:
12.5 - (-3.7)
12.5 + 3.7

What is the distance between points (-3 -5) and (-3 -7)?
Please help I’m tryna bring up my grade
Answer:
hope it helps you...........
Answer:
The distance is 2 units.
Step-by-step explanation:
Given Data:
Point 1: (-3, -5)
Point 2: (-3, -7)
Distance Formula:
[tex]\sqrt{(x2 - x1)^{2} + (y2-y1)^{2} }[/tex]
Substitute the given values and solve:
[tex]\sqrt{(-3 --3)^{2}+(-7--5)^{2} }[/tex]
[tex]\sqrt{0^{2} +(-2)^{2} }[/tex]
[tex]\sqrt{0+4}[/tex]
[tex]\sqrt{4}[/tex]
= 2
Answer = 2
hope this helps and is right!! p.s. i really need brainliest :)

Find the rule, and type the missing number in the sequence
96, 192, _, 384
Answer:
96, 192, 288, 384
Step-by-step:
First we find the difference between the first 2 digits so we subtract them both from each other
192-96
which is
=96
therefore its safe to say that +96 is the rule of the sequence
so I did 192+96 to find the missing number which gave me
=288

Well first you'd need to turn the fractions to improper, for instance you'd need to turn 1 1/3 from a mixed number to an improper fraction you do this by, keeping your denominator and then multiplying 3x1 and adding the 1, after that your final fraction should be 4/3 you also do this for your other fractions, let's remember that we still need to make 17 5/6 improper and 10 2/5 improper. so 17 5/6 will turn into 107/6 we are basically just doing 17x6 plus 5, now 10 2/5 will turn into 52/5 then we will have to simplify our fractions and subtract

3/4h × 19 mi/1/4 h =
Answer:
57 miles
Step-by-step explanation:
First, do 19 ÷ 1/4. This is the same as 19 × 4 which is 76. Then do 3/4 × 76. 76 ÷ 4 = 19 and 19 × 3 is 57. The unit is miles because the two h's cancel out.
Hope this helps!
