Answer:
3x-5=3
Step-by-step explanation:
Answer:
2.6 repeating Or 8/3(same thing in fraction form)
Step-by-step explanation:
So, lets iscolate the different parts of this euqation:
Five less than 3 times a number is 3
Or:
5 less than 3 * x = 3
This is a bit tricky here, but it should be:
(3*x)-5=3
Since order of operations, multipcation comes first.
And remember this is 5 less than the 3*x, so its subtracting 5 from 3*x.
This is all equal to 3.
Now lets solve:
(3*x)-5=3
Solve whats in the parthese first:
3x-5=3
Then get 3x alone:
3x=8
Then get x alone:
x=8/3
Or
2.66 repeating
This is your answer(8/3 or 2.6)
Hope this helps!
At the city Museum child admission is $6.40 in adult admission is $9.70 on Sunday 149 tickets were sold for a total sales of $1145 how many adult tickets were sold that day
Answer:
Adult=58
Step-by-step explanation:
c=child, a=adult
6.4c+9.7a=1145 equation 1
c+a=149 equation 2
a=149-c modified equation 2 to isolate a
6.4c+9.7(149-c)=1145 substitute value of a from equation 1 into equation 2
6.4c+1445.3-9.7c=1145
-3.3c=-300.3
c=91
solve for a
c+a=149
91+a=149
a=58
Check answer:
6.4c+9.7a=1145
6.4(91)+9.7(58)=1145
582.40+562.60=1145
1145=1145

Solve for V . 7v-20=-6(v-1) Simplify your answer as much as possible.
Answer:
v = 2
Step-by-step explanation:
You can start by distributing -6:
7v - 20 = -6v + 6
To combine the like x terms, you can add 6v to both sides:
7v - 20 = -6v + 6
+6v +6v
13v - 20 = 6
Now add 20 to both sides to isolate the x term:
13v - 20 = 6
+20 +20
13v = 26
You can divide by 13 on both sides to find v,
13v = 26
÷13 ÷13
v = 2
Answer:
v= 2
Step 1: Simplify both sides of the equation.
7v−20=−6(v−1)
7v+−20=−6v+6
7v−20=−6v+6
Step 2: Add 6v to both sides.
7v−20+6v=−6v+6+6v
13v−20=6
Step 3: Add 20 to both sides.
13v−20+20=6+20
13v=26
Step 4: Divide both sides by 13.
13v/13 = 26/13
v=2

Consider the equation x2 – 12x + 49 = 22. Which equation has the same solution(s) as the given equation?
Answer:
The correct solution is "x=3 or x=9".
Step-by-step explanation:
The given equation is:
⇒ [tex]x^2 - 12x + 49 = 22[/tex]
On subtracting "22" from both sides, we get
⇒ [tex]x^2-12x+49-22=22-22[/tex]
⇒ [tex]x^2-12x+27=0[/tex]
On factorizing the above equation, we get
⇒ [tex]x^2-9x-3x-27=0[/tex]
By taking common, we get
⇒ [tex]x(x-9)-3(x-9)=0[/tex]
⇒ [tex](x-3)(x-9)=0[/tex]
⇒ [tex]x-3=0[/tex]
[tex]x=3[/tex]
Or,
⇒ [tex]x-9=0[/tex]
[tex]x=9[/tex]

Which equation represents the data in this function table?
A. y = x + 4
B. y = x - 4
C. y = 4x
D. x = y + 3
Answer:
A.
Step-by-step explanation:
If you put the x value of the table and use it in each equation, only one gives the y output on the table.
y=x + 4
5=1 + 4
6=2+4
7=3+4
8=4+4
9=5+4
The correct option is A) y=x+4
What are linear equations?Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.
Given here option A as y=x+4 now lets verify this option
if x=1 then y = 1+4
= 5
Again if x=2 then y =2+4
=6
Similarly it can be clearly observed that all the values of y are 4 greater than the input of x given in the table.
Hence, option A is the correct answer.

Step-by-step explanation:
2+3=5, 5+3=8, 8+3=11. 2x3=6, 5x3=15, 8x3=24, 11x3=33
Answer:
A
Step-by-step explanation:
Proportional is where everything will match
so we have 2x3=6 5x3=15 8x3=24 11x3=33
This works because it continues the same line of multiplication (x3).
But like B, you start with 4,4=16 which works, but now you have 5x4=21, which will not work because 5x4 will never equal 21

Solve for line segment AB
Answer:
AB = 32
Step-by-step explanation:
Given:
AD = 40
CD = 9
Required:
Find the length of segment AB
Solution:
BC and CD are radius of the circle. Therefore,
BC = CD = 9
AB = AC - BC
AB = AC - 9
We need to find AC
Since AD is tangent, CD is perpendicular to AD, this means that <D is a right angle. This makes ∆ADC a right triangle.
Therefore, we can apply Pythagorean theorem to find AC.
Thus:
AC² = AD² + CD²
AC² = 40² + 9²
AC² = 1,681
AC = √1,681
AC = 41
Let's find BC:
AB = AC - 9
Plug in the value of AC
AB = 41 - 9
AB = 32

one number is 8 times a first number. a third number is 100 more than the first number. if the sum of the three numbers is 480, find the numbers
Answer:
Step-by-step explanation:
Let the first number = x
Let the second number = 8x
Let the third number = x + 100
x + 8x + x + 100 = 480 Combine like terms
10x + 100 = 480 Subtract 100
- 100 -100
10x = 380 Divide by 10
x = 380/10
x = 38
First number = 38
Second number = 8*38 = 304
The third number = 38 + 100 = 138

The following are six observations collected from treatment 1, four observations collected from treatment 2, and five observations collected from treatment 3. Test the hypothesis at the 0.05 significance level that the tre atment means are equal.
a) state the null and the alternate hypotheses
b) What is the decision rulec).
c) Compute SST, SSE, and SS total
d) Complete an ANOVA table
e) State your decision regarding the null hypothesis

Treatment 2
13, 20, 14, 13
Treatment 3

Answer:
Since the calculated value of F=0.20 does not fall in the critical region
F ≥ = 3.481 we reject the alternate hypothesis and accept the null hypothesis and conclude that there is no difference between the means of the 3 treatments.
Step-by-step explanation:
As the sample size are different we can run anova in the excel.
Part a)
The null and alternate hypotheses are
H0: μ1=μ2=μ 3 against the claim Ha: Not all three means are equal
The significance level ∝ is chosen to be 0.05
Part b)
The critical region is F≥ F(0.05,5,9) = 3.481
