A family spent $169 at the movies. Admission tickets cost $12 apiece, and a bucket of popcorn costs $7 which equation written in standard form.
How many buckets of popcorn could be bought if a family buys 7 admission tickets?
Answer:
12
Step-by-step explanation:
7 (number of tickets) times 12 (cost of ticket) = 84 169 (total spent) - 84 (total ticket price) = 85 85 divided by 7 (price of popcorn) = 12.14 round down as they wouldn't have enough money to buy more than 12 popcorns.

Answer:
[tex]7\frac{1}{4}[/tex]
Step-by-step explanation:
Change to improper fraction.
[tex]8\frac{1}{2}[/tex] ⇒ [tex]\frac{17}{2}[/tex]
[tex]1\frac{1}{4}[/tex] ⇒ [tex]\frac{5}{4}[/tex]
Find the least common denominator (LCD) of the two fractions. ⇒ 4
[tex]\frac{34}{4}[/tex] - [tex]\frac{5}{4}[/tex] = [tex]\frac{29}{4}[/tex]
Convert to a mixed number.
[tex]\frac{29}{4}[/tex] ⇒ [tex]7\frac{1}{4}[/tex]
Hence, [tex]8\frac{1}{2} - 1\frac{1}{4} = 7\frac{1}{4}[/tex]

Answer:
y = -0.5x - 7 or y = -1/2x - 7 (both are same)
Step-by-step explanation:
m = slope
slope = y2 - y1 / x2 - x1
-9 - (-8) / 4 - 2 = -1/2 = -0.5
m = -0.5
b = y-intercept
b = -7
y = mx + b
y = -0.5x + (-7)
y = -0.5x - 7
(negative slope)

3,000 + 600 + 42
3,000 + 60 + 13
3,000 + 60 + 42
300 + 60 + 42
Answer:
3000+60+42
Step-by-step explanation:
the order of operations says to multiply and divide from left to right before adding or subtracting from left to right. Putting the numbers in parenthesis helps.
(500*6)+(10*6)+(7*6)
(3000)+(60)+(42)
3000+60+42

Natasha has a job putting letters in envelopes to be mailed. in 1 hour she put 42 letters in envelopes. which equation best represents y, the total number of letters natasha puts in envelops in x hours if she continues
Answer:
36 pages .394kb
Step-by-step explanation:
that's it well done
You can use multiplication along with converting statements to symbols.
The equation for the given condition is given by [tex]y = 42x[/tex]
where y represents the total number of letters Natasha puts in envelops in x hours.
How to form symbolic expressions from the description?You need to know how to convert the statement to symbolic expression.
Suppose if it is said that a thing is increased by 4,then we write it as
that thing + 4
Suppose if it is written that 'x' objects are sold on p price per object. Since 1 object is sold at p price, then x objects will be sold at:
[tex]p + p + ... + p \: \: \: (x \: \: times) = p \times x[/tex]
Such conversion can help us to form symbolic expressions from the given description.
Since for the given case, in 1 hour, Natasha put 42 letters in envelopes, then in x hour she will put:
[tex]42 + 42 + ... + 42 \: \: (x \: times) = 42 \times x[/tex]
Since in x hours, she puts y envelopes but envelopes put in x hours came out as 42 times x, thus, both the values are equal, or
[tex]y = 42 \times x = 42x \text{\:\:(written in short)}[/tex]
The equation for the given condition is given by [tex]y = 42x[/tex]
where y represents the total number of letters Natasha puts in envelops in x hours.

How many points of intersection are on the graph of the following system?
lbrace y = x2 + 3x − 7
y − x = 9
The linear-quadratic system has
(select)
points of intersection.
Answer:
2 points of interception of (3.12 , 12./12) and (-5.12 , 3.87)
Step-by-step explanation:
y − x = 9
y = x + 9
x+9 = x²+3x-7
x²+2x-16=0
x = (-2±√2²-4(1)(-16)) / 2 = (-2 ± √68) / 2 = -1 ± √17
x = 3.12 or x = -5.12
y = 12.12 or y = -3.87

Graph D (last graph)
Step-by-step explanation:
y + 2 > 5
first subtract 2 from both sides
y > 3
Now that we know the solution to y we can plot it. We know it must start at 3, but also not be included because our solution is not ≥. This means we have an open box at 3 and an arrow in the positive direction.
