Answer:
The four consecutive multiples of three are 6, 9, 12, and 15
Step-by-step explanation:
let the first multiple of 3 = n
second multiple of 3 = (n + 3)
third multiple of 3 =(n + 6)
fourth multiple of 3 =(n + 9)
product of the first and the third = n(n + 6) = n² + 6n
eight times the fourth number = 8(n + 9) = 8n + 72
The difference between the two = n² + 6n - (8n + 72) = -48
n² + 6n - 8n - 72 = -48
n² - 2n = -48 + 72
n² - 2n = 24
n² - 2n - 24 = 0
n² - 2n - 24 = 0
n² + 4n - 6n - 24 = 0
n(n + 4) - 6(n + 4) = 0
(n - 6)(n + 4) = 0
n = 6 or - 4
n should be a positive number, thus n = 6
The second multiple of 3 = (n + 3) = 6 + 3 = 9
The third multiple of 3 =(n + 6) = 6 + 6 = 12
The fourth multiple of 3 = (n + 9) = 6 + 9 = 15
A dentist surveyed ten 9 year old patients to see How Many Teeth they have lost so far. The results were: 4, 3, 4, 8, 8, 12, 9, 6, 10, and 6. What is the range for this data set ?
Answer:
9
Step-by-step explanation:
Summary: The range of a set of data is difference between the highest and lowest values. To find the range, first order the numbers from least to greatest. Then subtract the smallest value from the largest value in the set.

Answer:
this is a right angled triangle
so by the Pythagoras theorem
h2 = √ p2+. b2
h2 = √2 square + 6 square
h2 = 4+ 36
h2 = 40
h = √40
h = 20
Answer:
c=6.3cm
Step-by-step explanation:
6²+2²=c²
36+4=c²
40=c² -> (√40 ≈ 6.32)
6.32 ≈ 6.3

Answer:
x=1
Step-by-step explanation:
given
21=14+7x
our objective is to get the variable (x) by itself
To do so we use inverse operations
so to get rid of the 14 we subtract 14 but whatever you do to one side you have to do to the other so we subtract each side by 14
14-14 cancels out
21-14=7
now we have
7x=7
now we want to get rid of the 7
to do so we divide by 7 but remember whatever we do to one side we have to do to the other side so we divide each side by 7
7/7 cancels out
7/7=1
we're left with x=1
hope this helps!

Ashley is saving for a computer that costs $500. She has saved up $120
so far. Which inequality represents the amount of money, m, Ashley still
needs to save? *
O m > $120
O m<$120
O m< $380
O m > $380
Answer:
m > $380
Step-by-step explanation:
First, the math:
$500-$120= $380.
She still needs $380.
Her $380 still needed is less than m, which gives us the last answer the most logical.
I hope this helped! Have a nice day.

Answer:
The surface area is 294 inches squared
Step-by-step explanation:
9 x 3 = 27 x 2 = 54
10 x 3 = 30 x 2 = 60
9 x 10 = 90 x 2 = 180
54 + 60 + 180 = 294

What is the value of X
Answer:
112*
Step-by-step explanation:
The easy way to figure this out is to take the two numbers we do have and add them together. 50 + 62 = 112
We now now the complete angle if that line was not there in the middle. and sice that angle is the same at angle X it is automatically the same, 112. If you don't understand please comment and let me know.

Answer:
x = 9 (it is seriously not drawn to scale)
Step-by-step explanation:
BC = DC^2 + BD^2 (Pythagorean theorem)
BC = 4^2 + 6^2
BC = 16 + 36
BC = 52^2
BC = 2sqrt13
BC/AB = DC/BD
(2sqrt13)/AB = 4/6
6(2sqrt13) = 4(AB)
12sqrt13 = 4AB
3sqrt13 = AB
AC^2 = AB^2 + BC^2 (Pythagorean Theorem)
AC^2 = (3sqrt13)^2 + (2sqrt13)^2
AC^2 = 117 + 52
AC^2 = 169
AC = 13
AD + DC = AC
AD + 4= 13
AD = 9

Given:
The figure of a triangle DEF.
To find:
The coordinate of image of given triangle after reflection over y-axis.
Solution:
The vertices of given triangle are D(1,4), E(4,3), F(2,0).
If a figure is reflected over the y-axis, then the rule of reflection is
[tex](x,y)\to (-x,y)[/tex]
Using this rule, we get
[tex]D(1,4)\to D'(-1,4)[/tex]
[tex]E(4,3)\to E'(-4,3)[/tex]
[tex]F(2,0)\to F'(-2,0)[/tex]
Therefore, the coordinates of image are D'(-1,4), E'(-4,3) and F'(-2,0).

Answer:
3675
Step-by-step explanation:
Use the order of operations. Just go from left to right. So, 7 times 7 equals 49. Then, 49 times 7 equals 343. Then, divided by 7 equals 49. 49 times 75 equals 3675. I hope this helps.
Solve the equation.
8-2x = -8x + 14
O x=-1
O x= -3/5
Ο χ=3/5

Answer:
0.98
Step-by-step explanation:
0.98 would be the most logical answer. If there is a 0.2 percent chance, it has a 20% chance of happening, which isn't likely. If there is a 0.5 percent chance, it is split so it can't really be likely or unlikely. Whereas having a 0.98 percent chance means there's a 98% of it happening.

You have 23 questions and each questions takes 2 minutes and two weeks to complete what is the longest time you have to finish it
Answer:
46 minutes
Step-by-step explanation:
Number of questions = 23
Time taken per question = 2 minutes
The longest time available to finish all questions :
Longest time will be ; if one spends all two minutes on each question ;
Then ;
Longest time = number of question * maximum time per question
Longest time = 23 * 2 = 46 minutes
Which graph represents the solution to the linear system
Sy=-3x-5
-5?
y= 3x +1
Answer:
Step-by-step explanation: both graphed is D
The graph D represents the solution of the system of the equation.
What is the system of equation?One or many equation having same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given, the system of equation;
y = -3x - 5 {equation 1}
y = 3x + 1 {equation 2}
Add both of the equation:
2y = -4
y = -2
And x = 1
And the solution set is (1 , -2).
And only D have the solution set (1 , -2)
Therefore, the graph D represents the solution of the system of the equation.

Find the angle measure of angle E in Triangle DEF if angle D is 34 degrees & angle E is 117 degrees.
Answer:
m∠E = 29°Step-by-step explanation:
The sum of the measure of the interior angles in a triangle is 180°
m∠D + m∠E + m∠F = 180°
34° + m∠E + 117° = 180°
m∠E = 29°
