-0.03x^2+1.53x=0
how would i go about solving for x?
Answer:
x = 0, 51
Step-by-step explanation:
→First, you need to factor out the GCF (Greatest Common Factor), which is -0.03x, like so:
-0.03x (x - 51) = 0
→Remove the -0.03 by divide it by both sides:
x(x - 51) = 0
→Separate each, like so:
x = 0
x - 51 = 0
→Solve for x:
x - 51 = 0
x = 51
Your solutions are, 0 and 51.
A cell phone plan costs $200 to start. Then there is a $50 charge each month. Write an equation relating the cost, y, and then number of months, x.
Answer:
y = 200 + 50x
Step-by-step explanation:
y = cost
x = number of months
The cost is equal to the cost to open the plan plus the monthly fee times the number of months
y = 200 + 50x
Answer:
y = 200 + 50x
Step-by-step explanation:
the cost = the base cost plus the monthly charge ($50 per the number of months you pay it)

Solve using cosine law only
Please please help this is due tomorrow morning
Hints:
Step 1: Use Sine law the the angle B.
a/Sin A=b/SinB=c/SinC
24/Sin61^=12/SinB (accross multiply)
SinB=12Sin61^/24
SinB=0.437309853 then convert to degree =25.9 degree( depends on question rounded how many decimal) Read the question it must notes there.
--> Angle C=180-61-25.9=93.1 degree.
Step 2: Use Cosine law to calculate.
c^2=a^2+b^2−2ab⋅cosC
c^2=24^2+12^2-2(24)(12)cos93.1
c^2=720-576(-0.054078812)
c^2=720+31.11494
c^2=751.1494
c=27.4

Ross has a fourth of the amount needed to buy a new computer. The computer cost ($213 divided by 55) divided by 4. Show how you could calculate the amount of money ross has?
Answer:
The amount of money that Ross has = $0.97
Step-by-step explanation:
We are told in the question that Ross has a fourth of the Amount needed to buy his computer.
Let us represent cost of the computer as = Y
Hence, Ross has = 1/4 of Y
From the question, we are told the cost of the Computer. Therefore,
Y = $213÷ 55
Y = $3.8727272727 = $3.87
The cost of the computer = $3.8727272727
Since Ross has 1/4 of the amount needed for the computer ,
This is calculated as : 1/4 × $3.8727272727
=$0.9681818182
Approximately: $0.97
Therefore, The amount of money that Ross has = $0.97
Answer:
0.97

What is the value of y easy
Jenny recorded the number of basketball shots she made for each game. The histogram below shows her data. How many times did Jenny make less than four shots in a game?
a. 4
b. 7
c. 5
d. 1
Answer:
Answer choice a is correct, the answer would be 4.
Step-by-step explanation:
The histogram shows that the bin from 1-3 has a height of 4 shots, and all of the bins to the right include values of ≥4.
The question asks for the number of games that had less than 4 shots, which means that and number of shots greater than or equal to 4 would not be counted. Thus, only the first bin is included in the answer.
From a point at the waters edge, a bridge arch 53 m away has an angle of elevation of 30, and the top of a yacht mast 14 m away has an angle of elevation of 12°. Can the yacht pass under the bridge?
Answer:
Yes
Step-by-step explanation:
We don't even have to do a calculation.
The arch of the bridge is at point C.
The top of the yacht's mast is at E.
Even though the yacht is much closer to the water's edge, its mast has a much smaller angle of elevation.
The yacht can easily pass under the bridge.
plz help with slope question
Answer:
-The equation:
[tex]y = x + 2[/tex]
Step-by-step explanation:
Use the Point-slope formula to get the slope-intercept equation:
[tex]y-y_{1} = m(x-x_{1})[/tex]
Use the given slope [tex]1[/tex] and point [tex](3,5)[/tex] for the point-slope formula:
[tex]y-5 = 1(x-3)[/tex]
-Then, solve:
[tex]y-5 = 1(x-3)[/tex]
[tex]y-5 = x - 3[/tex]
[tex]y-5 + 5 = x - 3 + 5[/tex]
[tex]y = x + 2[/tex]
-So, the answer is:
[tex]y = x + 2[/tex]
Answer:
C. [tex]y = x +2[/tex]
Step-by-step explanation:
→You can figure this out by plugging in the numbers into the point-slope form, like so:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-5=1(x-3)[/tex]
[tex]y - 5=x-3[/tex]
[tex]y = x +2[/tex]

Using system of equations answer this word problem. 1) Scott and Paul are selling Pies for a school fundraiser. Customers can buy apple pies and lemon meringue pies. Scott sold 3 apple pies and 12 lemon meringue pies for a total of 141$. Paul sold 2 apple pies and 5 lemon meringue pies for a total of 64$ What is the cost of each of one apple pie and one lemon meringue pie? (Show your work and tell me how to do it and I'll give you brainlist!)
Answer:
Step-by-step explanation:
We first need to come up with a system of equations that models this situation. Let's call apple pies "a" and lemon pies "L". Then we look to each individual involved in selling these pies and come up with an equation for each. Scott sold 3 apple and 12 lemon pies. The combination of this number of these 2 types of pies grossed him $141. In equation form, the combination of this number of these 2 types of pies is an addition thing. Namely,
3a + 12L = 141
For Paul, his combination was 2 apple and 5 lemon for a total of $64. His equation is
2a + 5L = 64
We need to solve this system either by substitution or elimination/addition to come up with the cost of both types of pies. I chose elimination/addition because I think in this case it is easier, and easier is good.
Setting up for elimination/addition:
3a + 12L = 141
2a + 5L = 64
Let's first eliminate the a terms. That means that the coefficient on each a has to be the same but with different signs. The LCM of both 3 and 2 is 6, so we will multiply the top equation by 2 and the bottom equation by -3 (we could also have chosen to eliminate the L's first; we also could have chosen to eliminate the a's first but made the 2 negative instead of the 3. As long as you do the math correctly, you'll get the same answer regardless of how you choose to do it). Multiplying the first equation by 2 and the second by -3 gives us a new system:
6a + 24L = 282
-6a - 15L = -192
The reason this is called the elimination or addition method is because the goal is to eliminate, but you do that by adding the columns together. As you can see, 6a - 6a eliminates the a terms, right? What you're left with then is
9L = 90 and
L = 10
Now that we know the cost of a lemon pie, we can back sub in to solve for the cost of an apple pie. It doesn't matter which equation you back sub into, as long as it has both an L and an a in it. I'll choose the first equation we wrote when we took on this nightmare:
3a + 12L = 141. Subbing in 10 for L gives us
3a + 12(10) = 141 and
3a + 120 = 141 and
3a = 21 so
a = 7
That means that lemon pies cost 10 each and apple pies cost 7 dollars each.
When six is subtracted from five times a number, the result is 9
Given that, when six is subtracted from five times a number, the result is 9. The number is 3.
What is the number?Given that, when six is subtracted from five times a number, the result is 9.
Let the number be y, such that;
(5 × y) - 6 = 9
Next, we solve for y
(5 × y) - 6 = 9
5y - 6 = 9
5y = 6 + 9
5y = 15
y = 15 / 5
y = 3
Given that, when six is subtracted from five times a number, the result is 9. The number is 3.

2x - 3y = -6
Multiply the second equation by -2
-4x +6y = 12
Add this to the first equation
4x - 6y = -24
-4x +6y = 12

if m=3 3/4, what is the value of 3m
Answer:
The answer is 11 1/4.
Step-by-step explanation:
The value of 3m can be found by multiplying 3 by 3 and 3/4 by 3. We get 9 and 9/4 there. Then we simplify 9/4 into 2 1/4 and say the answer is 11 1/4.
