Answer:
B. equivalent
Step-by-step explanation:
Our two equations are:
Let's use substitution and plug in the expression 
for y in the second equation. That way, we're getting rid of a variable so we can solve for the other:
This means that there are an infinite number of solutions possible for this system - any x value will work. So, the answer is equivalent, because these two equations are essentially the same.
Answer:
ACBD
Step-by-step explanation:
Increases, gains, earnings, upward motion are all represented by positive numbers. Decreases, losses, spending, downward motion are all represented by negative numbers. Here are the sums:
A: -33.57 +14.98 = -18.59
B: 7 2/5 -3/5 = 7 +(2/5 -3/5) = 7 -1/5 = 6 4/5
C: 3 1/6 +2 1/2 = (3+2) +(1/6 +3/6) = 5 4/6 = 5 2/3
D: 23.66 -15.84 = 7.82
__
Least to greatest, their order is ...
A (-18.59), C (5 2/3), B (6 4/5), D (7.82)
Answer:
1/5 or 0.2 of the whole pizza
but it says that theres only 3/4 of the pizza there. so 3/4 of a pizza eaten by 5 people each person would get 0.15 of the pizza

Answer:
Volume of cylinder is 6285.71 square units.
Step-by-step explanation:
Given the radius of cylinder 10 units. The height is twice its radius. we have to find its volume.
r=10 units
⇒ Diameter, d = 20 units
Also given height is twice its radius.
⇒ Height=2(r)=2(10)=20 units
<h2><em><u>Volume of cylinder=πr^2h</u></em></h2>
= 22/7 × 100×20
=22/7 × 2000
= 44000/7
= 6285.71square units.
hence, volume of cylinder is 6285.71 square units.
