In order to run a roller coaster at the fair more then 27 people need to ride. If 12 people were in line,which number sentence would show how many more people would need to be in line to ride the roller coaster a x+12<27 b x+ 12 >27 c 27-12>x d 12-x>27
Answer:
B
Step-by-step explanation:
Since it says there has to be MORE than 27 people, 12 + x should be more than 27

Tasha's scores on her first five tests were as follows.
74, 90, 92, 83, 81
What would Tasha have to score on the sixth test to have a mean of 85?
5
85
90
95
Answer: 90
Step-by-step explanation:
74+90+92+83+81= 420
420+90= 510
510/6= 85
*I actually work all the numbers given like this until I got 85.
Answer:
I know I am almost a year late! lol But I just learned about it so I figured I could still help!
Step-by-step explanation:
The answer is 90.
Use this example/solution I was given to learn from:
Example:
Aaron's P.E. class is completing a unit on bowling. So every Friday afternoon for the last three weeks, they have bowled one game at a nearby bowling alley. His scores have been 121, 147, and 96. What would he have to bowl next time in order to have a mean score of 128?
Solution:
Let x represent Aaron's fourth and unknown score. To have a mean of 128, the sum of the four scores would have to be divided by 4. To get that sum by itself, multiply it by 4. You also have to multiply the desired mean of 128 by 4. So the sum of the four scores is equal to 128 times 4.
121 + 147 + 96 + x = 128 ∙ 4
• Substitute in the values of the four scores.
364 + x = 512
• Simplify.
364 - 364 + x = 512 - 364
• Subtract 364 from each side of the equation.
x = 148
• Simplify.
Aaron must score a 148 in order to have a mean score of 128.

If t= -3, then 3t^2 +5t +6 equals
A. -36
B. -6
c. 6
D. 18
Answer:
D
Step-by-step explanation:
substitute t=-3 in the equation
3(-3) squared +5(-3)+6=18
Step-by-step explanation:
According to the question , value of t = (-3) . So on directly putting t = (-3) in expression we have ,
[tex]\tt \to 3t^2 +5t+6 \\\\\tt\to 3(-3)^2+5(-3)+6 \\\\\tt\to (3)(9)-15 +6 \\\\\tt\to 27 - 15 +6 \\\\\tt\to \boxed{\orange{\tt 18 }}[/tex]
A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 2, 6 with the ordered pair 5, 0. Another straight line labeled B joins the ordered pair 0, 2 with the ordered pair 6, 6.
Part A: How many solutions does the pair of equations for lines A and B have? Explain your answer. (5 points)
Part B: What is the solution to the equations of lines A and B? Explain your answer. (5 points)
Answer:
A. one B. (3, 4)
Step-by-step explanation:
1. A good graph can answer both parts (see attached image).
2. Write equations for the two lines and find a simultaneous solution.
Line A: Slope from (2, 6) to (5, 0) is [tex]m=\frac{6-0}{2-5}=\frac{6}{-3}=-2[/tex]
Using point-slope form [tex]y-y_1=m(x-x_1)[/tex]
[tex]y-6=-2(x-2)\\y-6=-2x+4\\y=-2x+10[/tex]
Line B: Slopt from (6, 6) to (0, 2) is [tex]m=\frac{6-2}{6-0}=\frac{2}{3}[/tex]
Using point-slope form, the equation for Line B is
[tex]y-2=\frac{2}{3}(x-0)\\y=\frac{2}{3}x+2[/tex]
To find the simultaneous solution, set the y's equal.
[tex]-2x+10=\frac{2}{3}x+2\\-6x+30=2x+6\\-8x=-24\\x=3[/tex]
Find y using either equation to get y = 4.
What is -2x-5=4????
Answer:
-9/2
Step-by-step explanation:
-2x-5 = 4
+5 +5
-2x = 9
------ ------
-2 -2
x = -9/2
Answer:
[tex]x = - \frac{9}{2} [/tex]
Step-by-step explanation:
1) Add 5 to both sides.
[tex] - 2x = 4 + 5[/tex]
2) Simplify 4 + 5 to 9.
[tex] - 2x = 9[/tex]
3) Divide both sides by -2 to get the answer.
[tex]x = - \frac{9}{2} [/tex]
hence, the answer is x = -9/2.

Below are two parallel lines with a third line intersecting them.
If you can’t see it the number is 81
Answer:
x° = 81°
Step-by-step explanation:
From the diagram, we have;
Two parallel lines crossed by a common transversal
Therefore, the corresponding angle formed by the transversal and each of the parallel lines are equal
The given angle = 81°
The alternate exterior angle to the given angle = x°
When two parallel lines are crossed by a common transversal, the alternate exterior angles are equal
∴ x° = 81°.

I am confused. I believe it is 5(x^2+2)=45
Here is the problem: 5 times the square of a number and 2 is 45.
Answer:

We must follow order of operations rules here.
Let the number be x. Then 5x^2 + 2 = 45. No parentheses needed here.
Then 5x^2 = 45, and x = ±9

Factor out the GCF from the given polynomial. 10^3 + 16^2 - 18x 10^3 + 16^2 - 18x = (Type your answer in factored form.)
Correct question is;
Factor out the GCF from the given polynomial. 10x³ + 16x² - 18x. (Type your answer in factored form.)
Answer:
GCF = 5x² + 8x - 9
Step-by-step explanation:
The given polynomial is;
10x³ + 16x² - 18x
First thing is to inspect the coefficients and see the greatest number that all three can be divided by evenly without remainder.
The greatest number is 2.
Secondly let's inspect the variables to see what we can factor out.
They all contain x. Thus, x is a factor.
Thus, we will divide each term by 2x to obtain the GCF of the polynomial.
GCF = (10x³/2x) + (16x²/2x) - (18x/2x)
GCF = 5x² + 8x - 9

Answer:
EF = 68°
Step-by-step explanation:
If 2 chords of a circle are congruent then the corresponding arcs are congruent.
The central angle FDG is equal in measure to the arc that subtends it
arc FG = 68°
Given EF ≡ FG , then
arc EF ≡ arc FG, so
arc EF = 68°

2. ALMN and APMN are shown below. What additional information is necessary to prove
ALMN = APMN by HL?
Help please!!!
Answer:
The additional information necessary is option;
D. [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex]
Step-by-step explanation:
From the given figure, we have;
Given that ML ≅ MP,
The Hypotenuse Leg HL theorem of congruency is used to prove that a given number of right triangles based on the lengths of their hypotenuse and one of the legs. It states that two or more right triangles are congruent if they have equal lengths of both their corresponding hypotenuse side and one leg
To prove that ΔLMN and ΔPMN are congruent by HL, we will also be required to prove that ΔLMN and ΔPMN are right triangles
For ΔLMN and ΔPMN to be right triangles, the angles, ∠LNM and ∠PNM should be right angles = 90°
With ∠LNM = ∠PNM = 90°, then, line [tex]\overline {MN}[/tex] is perpendicular to line [tex]\overline {LP}[/tex] or [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex]
Therefore, the additional information necessary to prove that ΔLMN ≅ ΔPMN by HL is [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex].
