A car and a bus which are 280 miles apart are driving towards each other. The car is moving at 50 mph while the bus is moving at 55 mph. How long will it take them to meet?
Answer:
2.6667 hours
Step-by-step explanation:
Given that:
Distance between car and bus = 280 miles apart
What le moving towards each other ;
Speed of car = 55 mph
Speed of bus = 50 mph
Time it will take them to meet;
Time = distance / speed
Hence :
Total distance to be covered = 280 miles
Total speed = (55mph + 50 mph) = 105 mph
Hence ,
Time = 280 miles / 105 mph
Time = 2.667 hours
2 hours, (0.667 * 60 = 40.02
2 hours, 40 minutes

2.6667

Answer:
(-10,-3)
Step-by-step explanation:
okay so first, we can plot the points (-3,2) and (4,7) on a graph. after graphing these points, look at the difference between the y-values. this is 5 because 7-2 is 5. now, look at the x-values. this is 7 because 4-(-3) is 7. so this means we have to go on the other side of the midpoint (-3,2) and go 5 lines down from that point. this brings us at (-3,-3). now, we have to go 7 lines to the left. this is (-10,-3). this is the other endpoint.
you can also graph this on desmos to double-check.
hope this helps:)

Answer:
5/6
Step-by-step explanation:
1/2 = 3/6 because 1/2 x 3 = 3/6. 2/3 = 4/6 because 2/3 x 2 = 4/6. 3/6 plus 4/6 equals 7/6 or 1 and 1/6. 2 - 1 1/6 = 5/6.

Round to the nearest tenth.
Answer:
(Assuming they are both right triangles)
214.5 sq ft
Step-by-step explanation:
Area of a right triangle= leg×leg / 2
25×25 / 2 = 312.5
14×14 / 2 = 98
312.5-98= 214.5

-4p+(-6p) combine like terms to create an equivalent expression
Answer:
-10p
Step-by-step explanation:
-4p+(-6p) for me I like to think of the negative or subtraction sign
overpowering the positive or addition sign
so in this case
-4p-6p
then since the variable p is the same -4-6 is -10
the end result is -10p

heolp ASAPPPPPPP!!!! Suppose three riders rode a total of 182 miles.
If they used a total of 13 horses, and rode each horse the same number of miles, how many miles did they ride before replacing each horse?
HELP NOW
They rode
__________miles before replacing each horse.
Answer:
14 miles
Step-by-step explanation:
You divide. 132/13
Which gives you 14. Every 14 miles, the riders replaced a horse.
So, They rode 14 miles before replacing each horse.
Hope this helps:)
Answer:
14 miles
Step-by-step explanation:
182/13 = 14 miles
Assuming each horse was only ridden once
then a total of 16 horses were ridden for a total of 182 miles
182 miles /13 horses = 14 miles horse
Of course, if each horse was ridden more than once before being replaced the distance between replacements could be reduced.
Note that the fact that there were 3 riders is irrelevant.

I need up with this assignment PICTURE
Answer:
These lines are linear lines.
Step-by-step explanation:
Linear lines are straight lines. We can determine if a line is linear in one of a few ways, three being:
By looking at the lines. If they are straight, then they are linear.
By looking at a graph. If there is a constant rate of change within the graph (between the points), then the line is linear. A constant rate of change is when something is changing at a constant, or not-changing number. For example, if the rate of change is 3 (+3 or -3), and never any other number, then the line is linear.
By solving the equation. For a line to be linear, it has to be able to fit in the slope-intercept form (y = mx + b) (without any exponents). If the equation does not work for the line, then the line is likely non-linear. A linear line may also have two expressions that are equal to each other. It's a little hard to see the entire second equation in the picture, but it appears to be 4x - 7. Meanwhile, the first equation is -2x + 5. Clearly, both lines are linear as they both fit in/follow the slope-intercept form. The m's are: -2 and 4, and the b's are 5 and -7.

What is the equation of the line that passes through the point (-1,4) and has a slope of -5?
Answer:
y = -5x + 4
Step-by-step explanation:
In the equation y = mx + b , m stands for slope and b stands for the y intercept. In the coordinates (-1,4) the y value is 4 meaning that it's your y-intercept. The slope is already given to you so just add the X.
Answer:
y = -5x - 1
Step-by-step explanation:
Since you have the slope and a given point you can use the point-slope formula to solve for the y-intercept formula.
Point slope formula = y - y = m(x - x)
m = -5 (-1, 4)
y - 4 = -5(x +1)
y - 4 = -5x - 5
y = -5x - 1

What is the value of the expression (x – 2y)(x + 2y) when x= 4 and y = 2?
Answer:
0
Step-by-step explanation:
To solve this, you first plug in the 4 and 2 where the x and y's go, making the expression (4 - 2(2))*(4 + 2(2)). Then you solve each parenthesis (below).
(4 - 2(2))*(4 + 2(2)).
(4 - 4)*(4 + 4).
0*8

The factor of the trinomial will be (2x + 3) and (2x + 3). Then the correct option is D.
What is a factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The trinomial is given below.
⇒ 4x² + 12x + 9
Then the factor of the trinomial will be
⇒ 4x² + 12x + 9
⇒ 4x² + 6x + 6x + 9
⇒ 2x(2x + 3) + 3(2x + 3)
⇒ (2x + 3)(2x + 3)
⇒ (2x + 3)²
Then the correct option is D.
