What is the expression and value of "six less than nine times the sum of a number and eight" when n = 5? 9 (n + 8) minus 6; when n = 5, the value is 111. 6 minus 9 (n + 8); when n = 5, the value is 111. 9 (n) + 8 minus 6; when n = 5, the value is 47. 6 minus 9 (n) + 8; when n = 5, the value is 47.
Answer:
Answer:
The expression is 9(n + 8) - 6, the value is 111 ⇒ answer A plz mark me brainlest
Step-by-step explanation:
* Lets explain how to solve the problem
- We have a statement:
" six less than nine times the sum of a number and eight"
- When we solve we will start by the last part
- The last part is the sum of a number and 8
- Assume that the number is n
∵ The sum is the answer of adding
∴ The sum of a number and eight is ⇒ n + 8
- Nine times the sum
∵ The sum is n + 8
∵ Nine times means multiply the sum by 9
∴ Nine times the sum is ⇒ 9(n + 8)
- Six less than nine times the sum
∵ Nine times the sum is 9(n + 8)
∵ Six less than means subtract 6 from nine times the sum
∴ Six less than nine times the sum is ⇒ 9(n + 9) - 6
* The expression is 9(n + 8) - 6
- Lets evaluate the expression when n = 5
∵ 9(n + 8) - 6
∵ n = 5
∴ The value = 9(5 + 8) - 6
∴ The value = 9(13) - 6
∴ The value = 117 - 6
∴ The value = 111
* When n = 5 the value of the expression is 111
Step-by-step explanation:

Find the exact value of the expression: -6 3/5 - (-7 4/15) + 2 1/5
Answer:
Step-by-step explanation:
-6 3/5 - (-7 4/15) + 2 1/5
Combine the first and third terms first
-6 3/5 + 2 1/5 = - 4 2/5
Now deal with the second term
- (- 7 4/15) = 7 4/15
7 4/15 - 4 2/5
7 4/15 - 4 6/15 Add 15/15 to 7 4/15 Subtract 1 from the 7
6 19/15 - 4 6/15

In the figure, all lines intersect at point W.
What is the value of n?
Please help quick
Answer:
n = 15
Step-by-step explanation:
A straight line equals 180 degrees
Angle SWT is congruent to angle XWV meaning:
SWT (55 degrees) = XWV (55 degrees)
Set up an equation:
3n + 80 + 55 = 180
Combine like terms
3n + 135 = 180
Subtract both sides by 135 to isolate variable n
3n = 45
Divide both sides by 3 to isolate variable n
n = 15

Find the hypotenuse of a right triangle that has a 13cm leg and a height of 7cm
Answer:
14.76 cm
Step-by-step explanation:
Use the pythagorean theorem:
a² + b² = c²
Plug in the side lengths and solve for c:
7² + 13² = c²
49 + 169 = c²
218 = c²
14.76 = c
So, the hypotenuse is approximately 14.76 cm

How many liter of 15% weed killer mixture must be added to 5 liters of 10% weedkiller mixture to make 12% weed killer mixture?
Answer: 3 1/3 liter
Brainliest? <3
let x equal the number of liters of 15% weedkiller.
your equation is .15 * x + .10 * 5 = .12 * (x + 5)
simplify to get .15 * x + .10 * 5 = .12 * x + .12 * 5
simplify further to get .15 * x + .5 = .12 * x + .6
subtract .12 * x from both sides and subtract .5 from both sides and simplify to get .03 * x = .1
divide both sides by .03 to get x = .1 / .03 = 3.333333333 rounded to 9 decimal digits.
you would need 3.333333333 liters of 15% solution to be added to 5 liters of 10% solution to get 8.333333333 liters of 12% solution.
.15 * 3.333333333 = .5
.10 * 5 = .5
.5 + .5 = 1
5 + 3.333333333 = 8.333333333
1 divided by 8.333333333 = .12 which is equal to 12%.
Write an equation for the line that is perpendicular to Y=-3/7x+4 and passes through (-4,-5)
9514 1404 393
Answer:
y = 7/3x +13/3
Step-by-step explanation:
The equation of the given line is in slope-intercept form (y=mx+b), so we can see the slope (m) is -3/7. The slope of the perpendicular line is the opposite reciprocal of this, so is ...
m = -1/(-3/7) = 7/3
The y-intercept of the perpendicular line can be found from ...
b = y -mx
b = -5 -(7/3)(-4) = -15/3 +28/3 = 13/3
Then the slope-intercept equation of the perpendicular line is ...
y = mx +b
y = 7/3x +13/3
_____
Additional comment
You can get there a little faster using the point-slope form of the equation of a line. For slope m and point (h, k) that form is ...
y -k = m(x -h)
For our perpendicular line, the equation is ...
y +5 = 7/3(x +4)

1⁵ + 5² / 25⁰ - 5¹=
Answer: 6.5
Step-by-step explanation:
1 (to the power of 5) is 1 and 5 (to the power of 2) is 25.
25 (to the power of 0) is 1 and 5 (to the power of 1) is 5.
1 + 25 = 26 and 1 - 5 = -4.
Since the slash means division in math and any number to the power of 0 is always 1.
The answer would be: -6.5.
The solution for the expression [tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)}[/tex] after simplifying is,
[tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)} = \frac{- 13}{2}[/tex]
We have to give that,
The expression to simplify is,
⇒ [tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)}[/tex]
Simplify the expression by simplifying each term in a given fraction,
⇒ [tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)}[/tex]
Since,
1⁵ = 1
5² = 5 × 5
= 25
25⁰ = 25
5¹ = 5
Substitute all the values,
⇒ [tex]\frac{(1 + 25)}{(1 - 5)}[/tex]
⇒ [tex]\frac{26}{-4}[/tex]
⇒ [tex]\frac{-26}{4}[/tex]
Simplify the fraction in simplest form,
⇒ [tex]\frac{- 13}{2}[/tex]
Hence, The solution is, - 13/2
