A car and a van start driving from the same location. The car drives at 40 miles per hour, and the van drives at 52 miles per hour. After 7 hours, how far apart are the car and the van?
WILL MARK BRAINLY NO BOTS!!!
Answers
Answer:
84 Miles
Step-by-step explanation:
The car drove 40 miles per hour for 7 hours so the car traveled 40X7 which is 280 miles and the van traveled at 52 miles per hour for 7 hours so the van traveled 52X7 which is 364 miles so the difference between both is 84 miles.

Answer: well if I am correct, then 9/12 is equal to 3/4 so you then have to subtract 1/12 from 9/12 so 8 (8/12) would be what was taken away. (if you were to simplify 8/12 I believe that would be 2/3)

express the function graphed on the axes below as piecewise function
for x<-4
for x>2
Answers
Answer:
<--------o o------------->
-4 2
Step-by-step explanation:
Because the sign in the inequalities is only greater than/ less than (not equal to), we know that there is an open dot on x=-4 and on x=2.
From there, we shade the area on the graph that is true to the function. So, we can test points.
First we will test x=-5
-5<-4 --> this is true, so we will shade to the left of x=-4
Now test x=0
0<-4 --> this is false
0>2 --> this is also false, so the area between the two open dots will not be shaded
Now test x=3
3>2 --> this is true, so we will shade to the right of x=3
the perimeter of rectangle is 2x² + 4x - 4y. its length is (2x - 3y). find the breadth of rectangle
plz help fast plz plz
Answers
Perimeter = 2 (l + b)
2x² + 4x - 4y = 2 {(2x - 3y) + b}
2x² + 4x - 4y = (4x - 6y) + 2b
2x² + 4x - 4y - (4x - 6y) = 2b
2x² + 4x - 4y - 4x + 6y = 2b
2x² + 2y = 2b
(2x² + 2y)/2 = b
x² + y = b
Breadth = x² + y
The price of a gallon of unleaded gas has dropped to 2.85 today. Yesterday's price was 2.91. Find the percentage decrease. Round your answer to the nearest tenth of a percent.
Answers
Answer:
2.85 divided by 2.91 is 0.97938144329
so about 97.9 percent 2.1 percent decrease
Answer:
2.1
Step-by-step explanation:
put change over original times percent over 100

A textbook store sold a combined total of 328 math and history textbooks in a week. The number of math textbooks sold was three times the number of history textbooks sold. How many textbooks of each type were sold?.
Answers
Answer:
246 math and 82 history textbooks
Step-by-step explanation:
this one is a fun one
328 / 4 gives us a value of m and h which is 82
so 328 = 3x + y
328 = 3m(82) + 1h(82)
328 = 246m + 82h
328=328
Aaliyah is deciding between two parking garages. Garage A charges an initial fee of $8 to park plus $2 per hour. Garage B charges an initial fee of $4 to park plus $3 per hour. Let AA represent the amount Garage A would charge if Aaliyah parks for tt hours, and let BB represent the amount Garage B would charge if Aaliyah parks for tt hours. Graph each function and determine the interval of hours parked, t,t, for which Garage A is cheaper than Garage B.
Answers
The interval of hours for which Garage A is cheaper than Garage B is t > 4.
Let A represent the amount Garage A would charge if Aaliyah parks for t hours, and let B represent the amount Garage B would charge if Aaliyah parks for t hours.
Garage A charges an initial fee of $8 to park plus $2 per hour. Hence:
A = 2t + 8
Garage B charges an initial fee of $4 to park plus $3 per hour. Hence:
A = 3t + 4
For Garage A to be cheaper than Garage B:
2t + 8 < 3t + 4
8 - 4 < 3t - 2t
4 < t
t > 4
The interval of hours for which Garage A is cheaper than Garage B is t > 4.

A plane traveled 1500 miles with the wind in 2.5 hours and 1400 miles against the wind in the same amount of time. Find the speed of the plane in still air and the
speed of the wind
The speed of the plane in still air is
(Simplify your answer.)
Answers
Answer:
speed of plane = 580 mph
wind speed = 20 mph
Step-by-step explanation:
distance = speed * time
A plane traveled 1500 miles with the wind in 2.5 hours
1500 = (p + w) * 2.5
1500 = 2.5p + 2.5w
1400 miles against the wind in the same amount of time.
1400 = (p - w) * 2.5
1400 = 2.5p - 2.5w
Add the two bolded equations
2900 = 5p
Divide both sides by 5
580 = p
speed of plane = 580 mph
---------------------------
use either bolded equation to find the wind speed
1500 = 2.5p + 2.5w
substitute for p = 580
1500 = 2.5(580) + 2.5w
1500 = 1450 + 2.5w
Subtract 1450 fro mboth sides
50 = 2.5w
divide both sides by 2.5
20 = w
wind speed = 20 mph

A board is 65 inches long into two pieces, so that one piece is 7 inches shorter than twice the length of the other pieces. Find the length of two pieces
Answers
Answer: 24 in, 41 in
Step-by-step explanation:
Set shorter piece is x in, and another longer one is y.
1. x + y = 65
2. y = 2x - 7
plug in the second equation into y of the first equation, we get:
x + (2x - 7) = 65
x + 2x - 7 = 65
3x - 7 = 65 （Add 7 to the both side)
3x = 72 (Divide 3 to both side)
x = 24 in
Plug x in the second equations to slove y.
y = 2x - 7
y = 2(24) - 7
y = 41 in

A line that passes trough the point (7,3) with slope of -1 ( answer plesse I need help )
Answers
Answer:
Slope-Intercept Form:
The equation of a line in slope-intercept form is y=mx+b. Since we know that the slope is -1, the equation so far is y=-x+b. To find the value of b, substitute in the given point.
3=-7+b
Add 7 to both sides.
10=b
The equation of the line is slope intercept form is y=-x-10.
Point-Slope Form:
The equation of a line in point-slope form is y-y1=m(x-x1). Substituting in the given point and slope, the equation is y-3=-(x-7).
