The label on a \frac{1}{4}
alexgriva [62]

Answer:

183.63 square feet area is covered by seeds per pound

Step-by-step explanation:

Given

41\frac{1}{4} pound bag of seed cover an area of 7575 square feet

\frac{165}{4} pound bag of seed cover an area of 7575 square feet

Or

7575 square feet area is covered by \frac{165}{4} pound bag of seed

Area in square feet covered by one pound bag of seed

= \frac{7575}{\frac{165}{4} } \\= \frac{7575 * 4}{165} \\= 183.63 square feet

How do I solve this?
pishuonlain [190]
Good morning! So, what this question wants us to do is find each y value given its x value. Without the function it gives us already, this would be pretty difficult.
It gives us a function rule of y=2x+3. This means that we need to plug in each x value into the equation and solve for y. Let’s work on these first three.

y=2x+3} x=-4
y=2(-4)+3
y=-8+3
y=-5
So, if x=-4, then y=-5.

y=2x+3} x=-2
y=2(-2)+3
y=-4+3
y=-1
So, if x=-4, then y=-1.

y=2x+3} x=0
y=2(0)+3
y=0+3
y=3
So, if x=0, then y=3.

Try out the last one, and if you have any questions, comment below! Here are some extra x values if you need more practice.
Using the same function rule, y=2x+3, try to find the y value if x=-6, x=-3, x=5, or x=6.

Janice bought 3 movie tickets and 3 sodas and the total cost was $35.25. A ticket to the movie cost $5.25 more than a soda. How
Effectus [21]

Answer: a ticket to the movie costs $8.5

Step-by-step explanation:

Let x represent the cost of a movie ticket.

Let y represent the cost of a Soda.

Janice bought 3 movie tickets and 3 sodas and the total cost was $35.25. This means that

3x + 3y = 35.25 - - - - - - - - - -1

A ticket to the movie cost $5.25 more than a soda. This means that

x = y + 5.25

Substituting x = y + 25 into equation 1, it becomes

3(y + 5.25) + 3y = 35.25

3y + 15.75 + 3y = 35.25

6y = 35.25 - 15.75 = 19.5

y = 19.5/6 = 3.25

x = y + 5.25 = 3.25 + 5.25

x = 8.5
