(50 POINTS) Subtract. (−8.3x+4)−(3.2x−5)
Enter your answer, in simplified form, in the box. (Combine and simplify the equation.)
Answer:
Hello!!!Step-by-step explanation:
The first step for solving this expression is to remove the first set of parenthesis.
-8.3x+4 - (3.2x-5)
Remember that when there is a "_" sign in front of the parenthesis, we must change the sign of the expression to the following
-8.3x + 4 - 3.2x + 5
Collect the like terms with an x variable.
-11.5x + 4 + 5
Lastly, add the number to get your final answer
-11.5x + 9
Hope that helps you dear...

to solve the equation 4+3x^2-7x=0 using the quadratic formula, what are the values of a, b, and c
a = 3
b = -7
c = 4
Explanation
what you need to know:
[tex]a {x}^{2} + bx + c = 0[/tex]
what you have:
[tex]4 + 3 {x}^{2} - 7x = 0[/tex]
so you just rearrange them from highest exponent being on the left to lowest exponent being on the right:
[tex]3 {x}^{2} - 7x + 4 = 0[/tex]

What kind of solution is this? Prove it.
3+8x=8x+3
3=3
0=0
Answer:
all real numbers
Step-by-step explanation:
3 + 8x = 8x + 3
Subtract 8x from both sides.
3 = 3
Since 3 = 3 is a true statement, the solution is
x = all real numbers
Every number is a solution of this equation.

Answer:
x=-2
Step-by-step explanation:
1.1x +1.2x -5.4 = -10
Combine like terms
2.3x -5.4 = -10
Add 5.4 to each side
2.3x -5.4+5.4 = -10+5.4
2.3x = -4.6
Divide each side by 2.3
2.3x/2.3 = -4.6/2.3
x= -2

Is the equation conditional, an identity, or a contradiction? y - 11 + 3y = 6y + 4
Answer:
The equation is a conditional.
y = 7.5
Step-by-step explanation:
y - 11 + 3y = 6y + 4
4y - 11 = 6y + 4
4y - 4y - 11 = 6y - 4y + 4
- 11 = 2y + 4
- 11 - 4 = 2y + 4 - 4
2y = - 15
2y ÷ 2 = - 15 ÷ 2
y = - 7.5

Answer:
151
Step-by-step explanation:
First, you find the radius which is 8/2. Next, you square the radius which is 16. Now you multiply 16 by pi which is 50.26548246. Now you do 9 divided by 3 which is 3. Then you multiply 50.26548246 by 3 to get 150.7964474 or 151

Answer:
Step-by-step explanation:
65+3x-1=4+8x(the sum of two interior opposite angle are equal to the exterior angle formed)
64+3x=4+8x
64-4=8x-3x
60=5x
60/5=x
12=x
substitute the value of x
4+8x
4+8*12
4+96
100
therefore angle ZAB=100 degree

What is the fraction representation of 0.196 (6 repeating)?
Answer:
49/250 I think I'm not sure though
Answer:
[tex]\frac{59}{300}[/tex]
Step-by-step explanation:
Recall that [tex]\frac{x}{9}[/tex] returns the decimal [tex]0.\overline{x}[/tex]. In this case, we only want the 6 repeating. We can achieve this by finding the fraction excluding the 6 and then adding the repeating fraction with the 6.
0.19 as a fraction is simply [tex]\frac{19}{100}[/tex]
[tex]\frac{6}{9}[/tex] returns a repeating digit 6. However, we would like the 6 to be in the thousands place. Since it's already in the tenth place, we will divide the fraction by 100 to put it in the thousands place: [tex]\frac{6}{9}\cdot \frac{1}{100}=\frac{6}{900}[/tex]
Adding these two fractions, we get:
[tex]\frac{6}{900}+\frac{19}{100}=\frac{6}{900}+\frac{171}{900}=\frac{177}{900}=\boxed{\frac{59}{300}}[/tex]
1. Find the probability of rolling a sum less than 4 or a
sum greater than 8 when a pair of dice is rolled.
=============================================================
Explanation:
Refer to the chart below. The values in red up top add to the values in blue along the left column to get the 6 by 6 grid of values inside. This represents all of the possible ways to add up values on a pair of dice. There are 6*6 = 36 outcomes.
Of those 36 outcomes, we have 13 outcomes where we roll less than a 4, or greater than 8
outcome = 1+1 = 2outcome = 1+2 = 3outcome = 2+1 = 3outcome = 3+6 = 9outcome = 4+5 = 9outcome = 5+4 = 9outcome = 6+3 = 9outcome = 4+6 = 10outcome = 5+5 = 10outcome = 6+4 = 10outcome = 5+6 = 11outcome = 6+5 = 11outcome = 6+6 = 12These 13 results are shown in green boxes in the diagram.
Since we have 13 ways to get what we want, out of 36 total, the final answer as a fraction is therefore 13/36
13/36 = 0.3611 = 36.11% approximately

The plot below shows the amount of liquid remaining in 555 basketball players' water bottles after practice. All measurements are rounded to the nearest \dfrac14 4 1 start fraction, 1, divided by, 4, end fraction pint.
Answer:
3 times
Step-by-step explanation:
From the dot plot given ; distance between each tick mark is 1/4
Bottle with least water = 1/4
Bottle with most water = 3/4
Number of times bottle with most is more Than bottle with least :
All we need to do is divide the greatest by the least :
That is :
3/4 ÷ 1/4
3/4 * 4/1 = 12 / 4 = 3

Petra invests $8000 for 4 years she earned $2000 as compound interest find rate of interest
Answer:
r = 5.74%
Step-by-step explanation:
Compound interest formula is expressed as;
A = P(1+r)^t
P is the principal = $8000
A = P+I =8000 + 2000 = $10000
time t = 4years
Substitute
10000 = 8000(1+r)^4
10000/8000 = (1+r)^4
10/8 = (1+r)^4
1.25 = (1+r)^4
1.05737126344 = 1+r
r = 1.05737126344 - 1
r = 0.05737126344
r = 5.74%
This gives the rate of interest

3. Write a pair of linear equations which has the unique solution x= 1 , y= -1.
Step-by-step explanation:
The equations with solution x = 1 and y = (-1) will intersect each other at (1,-1) .
Equation 1 :-
Say slope is 1 .→ y - (-1) = 1 ( x -1)
→ y +1 = x -1
→ x - y -2 = 0
Equation 2 :
Slope = -1→ y - (-1) = -1( x -1)
→ y +1 = -x +1
→ x + y = 0

Which diagram is NOT a good model of 1/5÷6?
Answer:
The circle one
Step-by-step explanation:
What you need to do is count the number of squares or slices it has and then count how Buchanan the chunk is divided into, should be 6
==============================================================
Explanation:
Ignore the dashed smaller lines for now. The solid black vertical lines form 4 smaller equal pieces, and not 5. Each tickmark represents 1/4 and not 1/5
So if you wanted to represent a model for [tex]\frac{1}{4}\div 6[/tex], then you would use the lower left corner. However, we want that 1/4 to be 1/5 instead. So this is why the answer is the lower left corner.
Everything else is a correct model. We started dividing everything into 5 equal parts. Then we focused on one of those slices, and subdivided that slice into 6 equal parts. Imagine doing that for each slice and we should have 5*6 = 30 smaller pieces total. Hence [tex]\frac{1}{5} \div 6 = \frac{1}{5} \times \frac{1}{6} = \frac{1}{30}[/tex]
