Answer:
A
Step-by-step explanation:
1000000·2.5=2500000
2500000÷100=25000
1000000+25000=1025000
An airplane flies with a constant speed of 620 miles per hour. How long will it take to
travel a distance of 310 miles? Give your answer in minutes or hours.
Answer:
30 minutes
Step-by-step explanation:
Alright lets start by laying out what the problem gives us :
A plane flies 620 mph.
It is asking how long it will take to travel 310 miles.
We need to give our answer in minutes or hours.
So lets take mph and look at the full meaning "Miles per hour"
An hour has 60 minutes in it.
So really it is saying miles per 60 minutes as well as miles per hour
So you could say the plane is traveling 620 miles every 60 minutes.
So now lets look at the number 310.
Just looking at it I can tell you that 310 looks very close to half of 620, in fact it is exactly half!
So lets divide the 620 mph by the 310 miles it is asking and we get 2! Proving that 310 is half of 620.
Alright now lets divide both the number of miles and number of minutes :
620 miles per 60 minutes
divided by 2 both miles and minutes
310 miles per 30 minutes
So this is your answer. After this you get that it would take 30 minutes to travel 310 miles in a plane going 620 miles per hour!
I hope this helps and I could help you understand it. :)

Step-by-step explanation:
simplify the expression (sqrt3+i)(sqrt3-i) and write the result in the form a+bi
Answer:
4
Step-by-step explanation:
This expression is a difference of squares.
(√3 + i)(√3 - i) = (√3)²-(i)², which is
3 - (-1)
= 3 + 1
= 4

Write a quadratic function in vertex form whose graph has the vertex ( -5. - 1) and passes through the point (-2.2).
Answer:
[tex](\frac{1}{3})(x+5)^2-1[/tex]
Step-by-step explanation:
So first let's write a graph in vertex form with a vertex of (-5, -1)
We get
a(x+5)²-1
We now need to determine a
we know that when x= -2 y=2 which means we have
a(-2+5)²-1=2
Solve for a
a(3)²=3
9a=3
a=3/9
a=1/3
Now that we know what a is equal to we can write our equation
[tex](\frac{1}{3})(x+5)^2-1[/tex]
Fill in the table of values for the equation y=x+2
Answer:
(-5,-3) (0, 2) (3,5)
Step-by-step explanation:
Just plug the x values into the equation.
-5+2=-3
0+2=2
3+2=5
(x^2 - y^2)/(3x - 3y) = ?
Answer:
I don’t really know but I think you can get like (x-y)(x+y) = 3(x-y). And then you like do 3(x+y)(x-y)??
Step-by-step explanation:
Answer:
[tex]\frac{x+y}{3}[/tex]
Step-by-step explanation:
[tex]\frac{x^{2}-y^{2} }{3x-3y}[/tex]
use the difference of two squares formula
[tex]\frac{(x+y)(x-y)}{3y-3} \\\\factor out 3 \frac{(x+y)(x-y)}{3(x-y)} \\cancel out the common factor; (x-y)\\your answer is[/tex]
x+y/3

Just not entirely sure on my answer please help will vote Brainly
Answer:
The answer is x = 43
Step-by-step explanation:
Solve for B by simplifying both sides of the equation, then isolating the variable.
hoped helped!
Brainly, please?
Answer:
B = 43
Step-by-step explanation:
1. Distribute.
5b + 15 = 4b - 28 + 2b
2. Combine like terms.
5b + 15 = 6b - 28
3. Get B on one side.
5b + 15 = 6b - 28
-5b + 28 = -5b + 28
43 = b

What is the first step for plotting points on the coordinate plane
Answer:
Steps for Plotting an Ordered Pair (x, y) in the Coordinate Plane. Determine the x-coordinate. Beginning at the origin, move horizontally, the direction of the x-axis, the distance given by the x-coordinate. If the x-coordinate is positive, move to the right; if the x-coordinate is negative, move to the left.
5x - 4y = -10
y = 2x - 5
2 =
y =
Answer:
x=10
y=15
Step-by-step explanation:
Since we know y in terms of x, we can use substitution and say instead of-
5x-4y=-10
5x-4(2x-5)=-10
5x-8x+20=-10
-3x=-30
x=10
Substitute x into the equation-
y=2x-5
y=2(10)-5
y=20-5=15.
