Quotient of a number and 3 increased by -7 Equals negative 144
Answer:
x = -411
Step-by-step explanation:
Number = x
Quotient of a number and 3 : [tex]\frac{x}{3}[/tex]
(x/3) increased by (-7) : [tex]\frac{x}{3}+ (-7)[/tex]
[tex]\frac{x}{3} -7 = - 144\\\\\frac{x}{3}= -144 + 7\\\\\frac{x}{3}= -137\\\\x = -137*3[/tex]
x = - 411
Answer:
-411
Step-by-step explanation:
x / 3 + -7 = -144
x / 3 = -144 + 7
x = -137 x 3
x = -411

Answer:
$30
Step-by-step explanation:
s = shorts
t = tshirts
s + 2t = 60
s + 3t = 75
s + 2t = 60
rewrite
-2t -2t
s = 60 - 2t
s + 3t = 75
plug in
(60 - 2t) + 3t = 75
solve
60 - 2t + 3t = 75
60 + t = 75
-60 -60
t = 15
s + 2t = 60
plug in
s + 2(15) = 60
s + 30 = 60
-30 -30
s = 30

Item 9 Write an equation that you can use to find the value of x. Perimeter of triangle: 16 in.
Answer:
16 = 3x
Step-by-step explanation
Find the diagram attached.
Perimeter = sum of all its sides
Sum of all its sides= x+x+x
Sum of all its sides = 3x
Given perimeter = 16in
Equating both;
3x = 16
x = 16/3
x = 5.33in
Hence the value of x is 5.33 and the required equation is 16 =3x

the angle of a quadrilateral are in the ratio 1 : 2 :3 :4 if the sum of the angles of a quadrilateral is 360 degree find the measure of each angle
Answer:
Step-by-step explanation:
Let the angles of quadrilateral be
x, 2x, 3x , 4x
sum of all angles of quadrilateral = 360°
x + 2x + 3x + 4x = 360°
10x = 360°
x = 360/10 = 36°
Ans. the four angles are :-
x = 36°
2x = 2 × 36 = 72°
3x = 3 × 36 = 108°
4x = 4 × 36 = 144°

(4, 10)
y ≤ 2x + 1
To determine if (4, 10) is a solution to the inequality, we want to plug in the given values.
10 ≤ 2(4) + 1
[multiply] 10 ≤ 8 + 1
[add] 10 ≤ 9
Determine if this statement is true.
10 is greater than 9; therefore (4, 10) is not a solution to this inequality.
Hope this helps!
Answer:
No
Step-by-step explanation:
If you plug in 10 for y and 4 for x, you will get 10 ≤ 9 which is false.

If a number is added to a set that is far away from the mean, how does this affect standard deviation?
Adding a number to the set such that the number is further away from the mean, will increase the SD. This is because the average distance of the numbers from the mean increases.
The Standard Deviation will increase if a new number is added to the collection that deviates more from the mean. This is due to an increase in the standard deviation of the numbers.
How the standard deviation is affected if a number is added to a set that is far away from the mean?The standard deviation demonstrates how widely things vary or diverge from the mean (mean, or expected value).
The Standard Deviation will vary if all terms in the set are multiplied or divided by the same number. The Standard Deviation will vary by the same amount.
The same number will likewise be changed for the mean. Imagine an animated, proportionate size growth for the spatter. There will be a change in the "measure of spread". The distance between each term and the mean doubles if every term is doubled, but the distance between each term also doubles, increasing the standard deviation. The Standard Deviation gets smaller if each word is divided by two.
In general, the Standard Deviation is decreased when a new number is added to the set that is extremely close to the mean. Visualize the paint spatter on the wall. Would the dispersion be more or smaller if we paint a droplet extremely near the center? – decrease because there are now relative to before more droplets at the center.
