Answer:
D.
Step-by-step explanation:
Took 2020 middle school Ed unit test end of year

Let the capacity of bus be x students
And van be y students, now ;
From the given statements we get two equations ~


multiply the equation (2) with 2 [ it won't change the values ]


Now, deduct equation (1) from equation (3)




Therefore each bus can carry (x) = 45 students
Now, plug the value of x in equation (1) to find y ~







Hence, each van can carry (y) = 17 students in total.
Answer:
Step-by-step explanation:
Y=-2x+2.....(1)
Y=-2x-2.....(2)
Subtracting (1) from (2)
Y - Y = -2x - (-2x) -2 - 2
O = -2x + 2x - 4
O = 0 - 4
Hence it as no solution the the two variables tend to zero
Answer:
Line A
Step-by-step explanation:
A line of symmetry is a line that divides a shape into exactly two equal halves.
A triangle is a polygon with three sides and three angles. A scalene triangle has no lines of symmetry, an isosceles triangle has more than one line of symmetry while an equilateral triangle has three lines of symmetry.
From the diagram we can see that line A divides the figure into two equal halves, hence line A is the line of symmetry.
Answer:
1/3 < 2/5 < 3/7 < 5/8 < 3/4
Step-by-step explanation:
Using the given inputs:
3/4 5/8 3/7 1/3 2/5
The least common denominator (LCD) is: 840.
Rewriting as equivalent fractions with the LCD:
3/4= 630/840
5/8= 525/840
3/7= 360/840
1/3= 280/840
2/5= 336/840
Sorting this by the numerators of the equivalent fractions in order from least to greatest:
1/3= 280/840= < 2/5= 336/840= < 3/7= 360/840= < 5/8= 525/840= < 3/4
= 630/840
Therefore, the sorted inputs in order from least to greatest is:
1/3 < 2/5 < 3/7 < 5/8 < 3/4
Hopes this helps!
Have a good evening! :)
