You divide the total pencils by the price, each pencil is $0.11 :)
1.99 / 18
Answer:
8 people in the original group.
Step-by-step explanation:
Let x be the number of people who were originally present for the dinner that cost $160. Their average cost per person would be:
$160/x
If 2 more people join, there are x+2 people. Ignoring the awkward situation that they apparently did not order any additional food, they agree to share the cost of the dinner. The average cost is now:
$160/(x+2)
We are told that this new average is now $4 less per person.
$160/(x+2) = ($160/x) - $4
$160 = (($160/x) - $4)(x+2)
x = 8 people
Answer:
x = 136°
Step-by-step explanation:
The opposite angles of a cyclic quadrilateral are supplementary, that is
x + 44° = 180° (subtract 44° from both sides )
x = 136°
Answer:
Explained Below
Step-by-step explanation:
first we need to turn the equation into point slope form.
3x + 4y = 12
4y = -3x + 12
y = -0.75 + 3
Parallel lines don't have a change in slope because they run parallel. Your answer would be -0.75 or -3/4.
