6 (2n + 5 ) = 66
solve for n
Answer:
n=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6(2n+5)=66
(6)(2n)+(6)(5)=66(Distribute)
12n+30=66
Step 2: Subtract 30 from both sides.
12n+30−30=66−30
12n=36
Step 3: Divide both sides by 12.
12n/12 = 36/12
n=3
Answer:
n = 3
Step-by-step explanation:
Distribute 6 into 2n+5, which is 12n +30
Subtract 30 from 66, which is 36
Divide 36 by 12
You're left with n = 3
Or in numbers:
6(2n+5)=66
12n+30=66
12n=36
n=3
Round to the nearest hundredth O(5x + 2) = 2(9x - 6) Type your answer...
Answer:
Solving the expression and round to the nearest hundredth
[tex]0(5x+2)=2(9x-6)[/tex] we get [tex]\mathbf{x=0.67}[/tex]
Step-by-step explanation:
We need to solve the expression and round to the nearest hundredth
[tex]0(5x+2)=2(9x-6)[/tex]
Solving:
[tex]0(5x+2)=2(9x-6)[/tex]
We know that multiplying anything by zero we get zero
[tex]0=2(9x-6)[/tex]
Switching sides
[tex]2(9x-6)=0[/tex]
Multiplying 2 with terms inside the bracket
[tex]18x-12=0[/tex]
Adding 12 on both sides
[tex]18x-12+12=0+12\\18x=12[/tex]
Divide both sides by 18
[tex]\frac{18x}{18}=\frac{12}{18}\\x=0.666[/tex]
Rounding to nearest hundredth we get:
[tex]x=0.67[/tex]
So, solving the expression and round to the nearest hundredth
[tex]0(5x+2)=2(9x-6)[/tex] we get [tex]\mathbf{x=0.67}[/tex]

Can someone tell just the answer
Answer:
Option D is correct .
Step by step explanation:
A function is given to us and we need to find its inverse . The function is g(x) = -2x⁵ - 2.
So for finding its inverse , exachange x with y .
⇒ g(x) = -2x⁵ - 2 .
Let g(x) = y ,
⇒ y = -2x⁵ - 2 .
Replace x with y ,
⇒ x = -2y⁵ - 2
⇒ x + 2 = -2y⁵
⇒ y⁵ = x+2 / -2
⇒ y⁵ = (-1) ( x + 2) / (-1)(-2)
⇒ y⁵ = -x - 2/ 2
⇒ y = ⁵√ [ ( -x -2)/2 ]
Hence the inverse of the function is ,
[tex]\boxed{\red{\bf f^{-1}(x)=\sqrt[5]{\dfrac{-x-2}{2}}}}[/tex]
Hence the correct option is (D) .You roll a dice twice.
Find the probability of getting 3 in first throw and 5 in second throw.
Answer:
1/6
Step-by-step explanation:
there are 6 faces on a dice so there's a 1 in 6 chance that you would roll a 3 on your second go there is still only a 1 out of 6 chance of getting a 5 because there is still 6 numbers you could roll on.

The expression for the total distance covered.
k + (k + 8) + (k - 2)
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Distance biked:
Jackson = k
Maria = k + 8
Peter = k - 2
Now,
The total distance biked.
= k + k + 8 + k - 2
= 3k + 6
= 3 (k + 2)
Thus,
The total distance covered is 3 (k + 2).

Find the value of X AND Y: Show your work.
We are given:
AB = 7x + 10
BD = 9x - 2
∠DBC = 9y - 9
∠ABC = 90°
AB = BD
Solving for x:
We are given that AB = BD
7x + 10 = 9x - 2 [since AB = 7x+10 and BD = 9x-2]
10 = 2x - 2 [subtracting 7x from both sides]
2x = 12 [adding 2 on both sides]
x = 6 [dividing both sides by 2]
Hence, x = 6
Solving for y:_______________________________________________
We know that AD is a straight line,
So, ∠ABC and ∠DBC must form a linear pair
∠ABC + ∠DBC = 180°
90 + 9y-9 = 180
9y - 9 = 90 [subtracting 90 from both sides]
9y = 99 [adding 9 on both sides]
y = 11 [dividing both sides by 9]
Hence, y = 11

fit on the braid is 12, what other fractions could
represent the part of the beads that are red?
Complete question :
Miranda is braiding her hair then she will attach beads to the braids she wants 1/3 of the beads to be red if the greatest number of beads that will fit on the braid is 12 what other fraction could represent the part of the beads that are red?
Answer:
2 / 6
Step-by-step explanation:
Fraction of red beads on braid = 1/3
greatest number of braids = 12
Fraction of red beads = (1 /3) * 12 = 4 red beads
Thus implies that :
When greatest number of braids = 12
fraction of red beads) = (Number of red beads / greatest number of beads)
Fraction = 4 / 12
Divide by 2 = 2/6 (don't reduce to lowest term).

A gallon of paint can cover 75 square feet. Maddie is painting a wall that measures 12x8.How many square feet will be uncovered if she only has one gallon of paint
12 x 8 is 96. Since a bucket of paint can cover 75,you would subtract 96 from the 75.That gives you 21.So if she only has one gallon,only 21 will remain unpainted.

Given: sin(A) = 4/5, pi/2 < A < pi and sin(B) = -2root5/5, pi < B < 3pi/2 What is the value of cos(A – B)?
Answer:
-√5/5
Step-by-step explanation:
Given the following
sin(A) = 4/5
sinB - -2√5/5
SinA = 4/5 = opp/hyp
We can get cosA
opposite = 4
hypotenuse = 5
Adj = √5²-4² (pythagoras theorem)
Adj = √25-16
Adj = √9
Adj = 3
Cos A = Adj/hyp
Cos A = 3/5
Also
Sin B = -2√5/5 = opp/hyp
opposite = -2√5
hypotenuse = 5
Adj = √5²-(2√5)² (pythagoras theorem)
Adj = √25-20
Adj = √5
Cos B = Adj/hyp
Cos B = √5/5
Evaluate cos (A-B)
cos (A-B) = cosAcosB + sinAsinB
cos (A-B) = 3/5(√5/5)+4/5(-2√5/5)
cos (A-B) = 3√5/25 - 8√5/25
cos (A-B) = -5√5/25
cos (A-B) = -√5/5
Hence the value of cos (A-B) is -√5/5
Shaneya purchased a membership to play basketball at her local gym. The membership costs $75 for the year, plus she pays $3 to rent equipment each time she goes. If Shaneya doesn't want to spend any more than $150 on basketball for the year, what is the maximum amount of times can she go to the gym to play?
Answer:
25
Step-by-step explanation:
Step one:
given data
We are told that Shaneya purchased a membership to play basketball at her local gym.
Costs = $75 for the year,
Rent = $3 for equipment each time she goes
Given that she has $150 to spend,
Step two:
Firstly, let us model the situation
let the total amount she has to spend be y
and the number of time she goes to the gym be x
y= 75+3x
for y= 150, let us find the value of x
150= 75+3x
150-75= 3x
75= 3x
divide both sides by 3
x= 75/3
x=25 times
The maximum amount of times is 25

You go to Macy’s and buy a watch costing $150. The watch is on sale for 60% off. What is the sale price after both discounts?
Answer:
Sale price of the watch = $60
Step-by-step explanation:
Given that:
Cost of the watch at Macy's = $150
Discount on watch = 60%
Amount of discount = 60% of cost
Amount of discount = [tex]\frac{60}{100}*150[/tex]
Amount of discount = 0.60*150 = $90
Price after discount = 150-90
Price after discount = $60
Hence,
Sale price of the watch = $60
