Maggie and Elizabeth are both cleaning their rooms. It takes Elizabeth three times as long as Maggie to clean her room. If all together they spent six hours cleaning their rooms, how long did it take each girl
Answer: Maggie used 1 1/2 hours
Elizabeth used: 3 × 1 1/2 = 4 1/2 hours
Step-by-step explanation:
Let the time used by Maggie be x
Since it It takes Elizabeth three times as long as Maggie to clean her room. Elizabeth will use: = 3 × x = 3x
Therefore, x + 3x = 6
4x = 6
x = 6/4 = 1.5 hours
Maggie used 1 1/2 hours
Elizabeth used: 3 × 1 1/2 = 4 1/2 hours
A new set of apple airpods cost $250 calculate the new price if you got a 20% discount and the sales tax 8%
Answer:
$216
Step-by-step explanation
We know that we are paying 80% of the price of the airpods (20% off) so we can multiply the full price by 0.8.
250 * 0.8
This will give us 200.
Now, we need to add the sales tax which is 8%.
Simply multiply the 200 by 1.08 since we are paying the 200$ plus an extra 8% of the cost.
200 * 1.08 = $216

Answer:
[tex] \boxed{y = - \frac{3}{4} x + 4}[/tex]
Step-by-step explanation:
The graph decreases. That meand the slope is in negative.
[tex]y = mx + b[/tex]
where m = slope and b = y-intercept. If the slope is positive, the graph will increase. Otherwise, decrease.
The only choice that the slope is negative is the third choice.

3. Elise bought 5 boxes of cereal and 2 gallons of milk for a total cost of $31.24. Each box of cereal cost $4.80. Enter the cost, in dollars of 1 gallon of milk. Note: do not include the dollar sign, $, in your answer. *
Answer:
3.62
Step-by-step explanation:
Let
x = cost of cereal
y = cost of milk
5x + 2y = 31.24
x = $4.80
Substitute into the equation
5x + 2y = 31.24
5(4.80) + 2y = 31.24
24 + 2y = 31.24
2y = 31.24 - 24
2y = 7.24
y = 7.24 / 2
y = $3.62
Therefore,
1 gallon of milk cost $3.62
simplify (2 1/4 - 1 2/3) multiplied by 1 5/7
The required simplified expression is 1.
Simplify (2 1/4 - 1 2/3) multiplied by 1 5/7
To simplify this expression, we first convert the mixed numbers to improper fractions:
2 1/4 = 9/4
1 2/3 = 5/3
1 5/7 = 12/7
Now, we can multiply the fractions:
(9/4 - 5/3) * (12/7)
Finding a common denominator (12), we can simplify the expression:
(27/12 - 20/12) * (12/7)
Simplifying further:
(7/12) * (12/7) = 1
Therefore, the simplified expression is 1.

Answer:
Step-by-step explanation:
The diagonals of a rectangle are equal.
2x + 10 = 56 That minus sign can't be there. Subtract 10 from both sides.
2x = 56 - 10 Combine
2x = 46 Divide by 2

25 POINTS PLEASE HELP!
Step-by-step explanation:
I think this is it :
For the schones a) 16,16 is double 8 so whatever the ingredients double them!
So it will be: 400g flour
60g caster sugar.... And so on
B) 4 is half 8, so whatever the ingredients half them
Flour = 100g
Sugar = 15g..... And so on
C) 24 is three time 8, so all ingredients triple them
Flour= 600g
Sugar = 90g...and so on
D) 40 is five times 8 so all ingredients multiply by 5
Flour= 1,000 g
Sugar= 150g.... And so on
E) 80 is 10 times 8
So multiply by 10
Flour = 2,000g
Sugar = 300g... And so on
F) 2 is one by fourth of 8
So, flour = 50g
Sugar = 7.5g
For ice-cream:
A) 8 is double 4 so whatever ingredient double
Double cream= 600ml
Milk= 640ml and so on
B) 2 is half 4 so make ingredients half
Double cream = 150ml
Milk = 160ml
C) here because it's only one person
U will divide all the ingredients by 4
So double cream = 300/4 =75ml
Milk = 320/4 = 80ml
So on...
D) for 3 people we will use bit c
For 3 people = double cream= 75x3= 225
Milk = 80x3 = 240ml
And so on
E) so for(c), we found for one person now we can easily use that and find this
Now for 6 people
For person, as we saw, = 75ml
For 6 people double cream = 75x6= 450ml
And for milk for 1 person = 80ml
For 6 people = 80x6= 480ml
And so on
F) 10 people
Double cream = 75ml x 10 = 750ml
Milk = 80ml x 10 = 800ml
For fish pie,
A) 15 is three times 5 so we will multiply 5 to each ingredient
Cod= 1500g
Haddock = 1200g and so one
B) for 1 person we will also divide each ingredient by 5 = Cod = 500÷5 = 100g
Haddock = 400÷5 = 80g and so one
C) we will use bit b for this too
Cod = 100 x 2 = 200g
Haddock = 80g x 2 = 160g and so on
D) 4 people
Cod= 100g x 4 = 400g
Haddock = 80 x 4 = 320g and so on
E) 8 people
Cod = 100 x 8 = 800g
Haddock = 80 x 8 = 640g and so on
F) 11 people
Cod = 100 x 11 = 1100g
Haddock = 80 x 11 = 880g
And so on

Hello!
[tex]\large\boxed{\text{C.} \frac{-15}{2}}[/tex]
3x + 5 = x - 10
Solve for x by isolating the variable.
Subtract 5 from both sides:
3x + 5 - 5 = x - 10 - 5
3x = x - 15
Subtract x from both sides:
3x - x = x - x - 15
2x = -15
Divide both sides by 2:
2x /2 = -15 / 2
x = -15/2.
Answer:
-15/12
Step-by-step explanation:
move the variables 3x-x+5=-10 and collect like terms 3x-5=-10-5 and divide both sides 2x=-15
x=-15/12
