Answer:
Step-by-step explanation:
1) moving fast
2)solar system
3)
6.50 + 2.50r = t
6.50 is being paid only once, while she pays 2.50 for each ride, or r. t is the total cost of the two when added together.
y = x + p - q
To make the formula's subject x, we must take the rest of the right hand side of the equation to the other side. So the answer is,
x = y - p + q
Y is usage so set y to 0 and solve for x
y = -10x+100
0 = -10x +100
subtract 100 from each side:
-100 = -10x
divide both sides by -10
x = -100 / -10
x = 10 hours
<u><em>The correct answers are:</em></u>
B, D, and E.
<u>A parallelogram</u> is a quadrilateral with both pairs of opposite sides parallel.
<u>A rectangle</u> is a parallelogram with all right angles, so yes, every rectangle is a parallelogram.
<u>A square</u> is a parallelogram with all right angles and all congruent sides; since it is a parallelogram with all right angles, every square is a rectangle.
<u>A rhombus</u> is a parallelogram with all congruent sides.
Since a square is a parallelogram with all congruent sides, then every square is a rhombus.
<u>A trapezoid</u> is a quadrilateral with one pair of parallel sides. Since a rhombus is a parallelogram, with 2 pairs of parallel sides, rhombus are not trapezoids.
