Answer: 2nd and 4th set
Step-by-step explanation:
1st set has no solution because the left side of the second equation is that of the first equation divided by 3, but the right side is not.
2nd set has 1 solution because it is the set of 2 lines with different slopes and y-intercepts.
3rd set has infinitely many solutions because multiplying the top equation by 1/3 gives you the bottom equation.
4th set has only solution for the same reason as 2nd set.
5th set has no solution because the two lines are parallel, but have different y intercepts, meaning they never intersect.

А.x=-6
В.x=6
C.x=8
D. r= 12
Answers
Answer:
D) x = 12
Step-by-step explanation:
we can change 5/2 to 10/4 and now have:
10/4x-7 = 3/4x + 14
we can subtract 3/4x from each side:
7/4x-7 = 14
add 7 to each side:
7/4x = 21
multiply each side by 4/7:
x = 84/7
x = 12

11) Tickets to a concert cost either $15 or
$20. A total of 300 tickets were sold and
the total receipts were $5300. How many
of each kind of ticket were sold.
Answers
Answer:
There were 140 tickets sold that cost $15 and 160 tickets sold that cost $20.
Step-by-step explanation:
To solve this problem, we should create a system of equations. Let's let the variable x represent the number of $15 tickets sold and let the variable y represent the number of $20 tickets sold. Using these variables, we can make the following equations:
x + y = 300
15x + 20y = 5300
To solve this equation, we can use substitution. Our first step in this case is solving the first equation for one variable; let's choose x.
x = 300 - y
Now, we can substitute this value for x into the second equation.
15(300-y) + 20y = 5300
Next we can distribute through the parentheses on the left side of the equation.
4500 - 15y + 20y = 5300
We can combine like terms on the left side of the equation to simplify.
4500 + 5y = 5300
We should then subtract 4500 from both sides of the equation.
5y = 800
Finally, we can divide both sides of the equation by 5.
y = 160
To solve for x, we can substitute this value for y into either of our original equations, but we should probably choose the first one for simplicity.
x + y = 300
x + 160 = 300
x = 140
Therefore, x = 140 and y = 160; this means that 140 $15 tickets were sold and 160 $20 tickets were sold.

Jane got a prepaid debit card with $25 on it. For her first purchase with the card, she bought some bulk ribbon at a craft store. The price of the ribbon
was 21 cents per yard. If after that purchase there was $16.39 left on the card, how many yards of ribbon did Jane buy?
yards
?
Answers
Step-by-step explanation:
so, she spent 25-16.39 = $8.61 on the ribbon.
1 yard of the ribbon costs $0.21.
how many yards did she buy with that amount of money ?
well, as many times as 0.21 fits into 8.61 :
8.61 / 0.21 = 41
so, she bought 41 yards of ribbon.
I'm happy to help you today!
Answer:
41 yards is correct
Step-by-step explanation:
Step 1. The information we have is:
Originally Jane had $25 on her debit card.
She made a purchase of bulk ribbon for 21 cents per yard.
And after that she ended up with $16.39 on the card.
Step 2. Make an equation to describe the situation.
The equation that describes this situation is:
[tex]\tt 25-0.21y=16.39[/tex]
Where 25 is the initial amount and to that, we subtract 0.21y, where y is the number of yards that she bought of ribbon. And all of this has to be equal to the final amount of 16.39.
Step 3. Solve the equation for y:
To solve for y, we subtract 25 to both sides of the equation:
⇒ [tex]\tt-0.21y=16.39-25[/tex]
⇒ [tex]\tt -0.21y=-8.61[/tex]
Then, divide both sides of the equation by -0.21:
[tex]\tt y=\frac{-8.61}{-0.21}[/tex]
The result is:
[tex]\tt y=41[/tex]
The answer is 41 yards of ribbon.

The hypotenuse of a 30°-60°-90° triangle measures 8√3 inches. What is the length of the shorter leg?
Answers
Answer: 8 inches
Step-by-step explanation:
In a 30-60-90 triangle, the ratio of the short side to the long side is 1/sqrt(3).
Therefore the short side is the long side divided by sqrt(3).
So the short side = 8 sqrt(3)/sqrt(3) = 8 inches

If the area of triangle is 360 cm2 and the height is 18cm, find its base
Answers
Formula for area of a triangle is 1/2 x base x height.
musing the information given you have:
360 = 1/2 x base x 18
First multiply both sides by 2:
720 = base x 18
Now divide both sides by 18:
Base = 720/18
Base = 40 cm
Solution:
Note that:
Area of triangle = 1/2 x Base x HeightArea of triangle = 360 cm²Height = 18 cmUsing the formula to find the area:
1/2 x Base x Height = Area of triangle=> 1/2 x Base x 18 = 360 cm²=> Base x 9 = 360 cm²=> (Base x 9)/9 = 360/9 cm²=> Base = 40 cmThe formula E= MHz, where E = gravitational potential energy , mass, g = gravity, and h= Height, is used to calculate gravitational potential energy. Solve this formula for h.

A room measure 9.68 metres long and 6.2 m wide Find its area Also find how many tiles will be needed to pave if the size of a tile 22cm × 10cm .
Answers
Answer:
Area is easy, just do 9.68*6.2 which = 60.02 (Rounded to the nearest hundreth)
Step-by-step explanation:
For how many tiles we need
60.02 m is the area of the room, each tile would be 22cmx10cm
There are 100 cm in 1 m
What we can do is find the area of the tiles
22x10 which is 220 CM
220CM is 2.2M
Now that we know the area of the tile is 2.2M we can do 60.02/2.2
Which would be 27.28 tiles (Rounding to the nearest hundreth)
Determine the slope and y-intercept given the equation below, explain your answer.
x + y = -1
Answers
Answer:
slope is -1, y-intercept is -1
Step-by-step explanation:
x+y=-1
convert to slope-intercept form
y=-x-1
y=-1x-1
slope is -1, y-intercept is -1
Solution:
Let's convert the equation into slope-intercept form.
x + y = -1y = -x - 1In this equation, the slope is the coefficient of x.
The following points can be made:
Since there is a "-" in front of the x variable, the coefficient of x is -1.Since the coefficient is -1, the slope of the line is -1.The y-intercept of the equation will be a constant.
The following points can be made:
Since there is a constant on the RHS, that constant will be the y-intercept.Since the constant on the RHS is -1, the y-intercept of the line is -1.In conclusion...
Slope of line: -1y-intercept of line: -1Solve the system of equations.
