The cost of one hat is $1 and cost of one mask is $1.
What is Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have 10 hats and 20 masks were sold for $30.
and, 8 hats and 10 masks were sold for $18.
let the cost of one hat be H and cost one Mask be M.
So, the system of Equation we get
10H + 20M = 30..........(1)
8H + 10M = 18...........(2)
Solving the above equation we get
10H - 16H = 30 - 36
-6H = -6
H = 1
and, 10 + 20M= 30
20M= 20
M= 1

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]

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) .I WILL GIVE YOU BRAINLY PLSS

Line passes through ( 2,4 ) with slope = 3
Answer:
the slope intercept-form of an equation of a line is y=mx+b
Given that the slope is 3 and a point on the line is P(-2, 4), then
m=3 and from the point (-2, 4), x=-2 and y=4.
Step-by-step explanation:
y=mx+b.
4=3(-2)+b Now solve for b.
4=-6+b
4+6=b
10=b
Now you know b=10 and you already know the slope m=3. Substitute these values into y=mx+b. When you do you will get y=3x+10. This is your answer in slope intercept form.

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

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

First you want to get n on the side by itself.
So 9n-24=4n+6 you want to add 24 to both sides so you get 9n=4n+30 than you want to subtract 4n from both sides to get 5n=30 than divide 5 from both sides to get n by itself and you will get n=6

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

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).
