Answer:

8

Step-by-step explanation:

11-3=c

c=8

The number of cubes Lucy should add is 8.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, a pan balance has 3 cubes on one pan and 11 cubes on the other pan.

The equation to represent the situation is 3+c=11

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Now, c=11-3

c=8

Therefore, the number of cubes Lucy should add is 8.

Answer:$6.84

Step-by-step explanation:

$4.25 + $2.25 = $6.50

5 1/4% in decimal form is 5.25%

6.50 multiplied by 5.25% = $0.34

$6.50 + $0.34 = $6.84

Step-by-step explanation:

The current sale price is if A computer store buys a computer system at a cost of ​$463.20. The selling price was first at $772​, but then the store advertised a 40% markdown on the system is $463.2.

The amount a buyer pays for a good or service is known as the selling price. It may differ based on the price that buyers are prepared to pay, the seller's acceptance threshold, and how competitive the price is in relation to those of other companies in the market.

Given:

The cost price = $463.20,

The initial selling price = $772,

We know that Markdown= Selling price × markdown rate

Markdown = 772 × 40%

Markdown = 772 × 0.4

Markdown = $308.8

So new selling price = The initial selling price - markdown price

Current selling price = 772 - 308.8

Current selling price = $463.2

Therefore, the current sale price is if A computer store buys a computer system at a cost of ​$463.20. The selling price was first at $772​, but then the store advertised a 40% markdown on the system is $463.2.

B.9 gallons in the gas tank and 280 miles.

From the given figure we see that the line of best fit passes through the point (13,400) and (17,520)

We know that the equation of a line passing through two point (a,b) and (c,d) is calculated by using the formula

y - b = d-b/c-a x (x-a)

Here we have:

(a,b)=(13,400) and (c,d)=(17,520)

Hence, the equation of line of best fit is: y - 400 = 520 - 400/17-3 x (x - 13)

y-400=120/4 x (x-13)

y=400=30x(x-13)

y-400=30x-390

y=30x-390+400

when x=0 we have:

y=10≠20

Hence, option: A is incorrect.

B)

when x=9 we have:

y=30×9+10

y=280

Hence, option: B is correct.

C)

11 gallons in the gas tank and 360 miles

when x=11; we have:

y=30×11+10

y=340≠360

Hence, option: C is incorrect.

D)

19 gallons in the gas tank and 520 miles

when x=19; we have:

y=580≠520

Hence, option: D is incorrect.

NUMBER 1

If 18 people is 40% that means the we need to start taking 40% off of numbers

40% of 20 is 12

40% of 25 is 15

40% of 30 is 18

So the answer is 30

NUMBER 2

If 21,000 people is 60% that means 20% is 7,000 people and 7,000x5=35,000 so there is a total of 35,000 people at the game

NUMBER 3

You should start taking 20% off of numbers.

20% of 25 is 20 too low so we need to go higher

20% of 26 is 20.8 still too low so lets keep going

20% of 27 is 21.60 closer but too low

20% of 28 is 22.40 which is too high lets go back since 27 is too low and 28 is too high lets start in between

20% of 27.5 is 22.00

So the answer is $27.5.

Answer:

y^8 goes to the last one

y^6 goes to the third one

y^5 goes to the second one

then the last one go to the first one

Answer:

(y)^-2 = 1/y^2, (y^3)^2 = y^6, y^8 -:- y^3 = y^5, and y^4 x y^4 = y^8

Step-by-step explanation:

When you divide y^8 -:- y^3, you subtract ^8-^3 = ^5, so its y^8 -:- y^3 = y^5

When you multiply y^4 x y^4, you add ^4 + ^4 = ^8, so it is y^4 x y^4 = y^8

When you multiply (y^3)^2, you multiply ^3 x ^2 = ^6, so its (y^3)^2 = y^6

And when you have a negative exponent,(^-2) you have to make it positive, so it would be y^-2 = 1/y^2

Answer:

the ans is 5

Step-by-step explanation:

2j+5=3+2j+2 cancel equal terms which is 2j

so what we have left is

5=3+2

5=5

so 5 is the ans

Answer: infinity many solutions

Step-by-step explanation:

2j + 5 = 3 + 2j + 2

Combine numbers in the right side

2j + 5 = 2j + 5

Minus the smallest j from both side in this case u get rid of both j’s which mean -2j

5 = 5

Divide by 1 or -5

Which mean we get 5 = 5 or 0 = 0

Hey there!

2^2 + 5 + 50 ÷ 2(5)

2^2 = 2 • 2 = 4

4 + 5 + 50 ÷ 2(5)

4 + 5 = 9

9 + 50 ÷ 2(5)

50 ÷ 2 = 25

9 + 25(5)

25(5) = 125

9 + 125

= 134

Answer:

the ratio is 18:81

Step-by-step explanation:

Okay so when a question is asking for a ratio it is basically asking a number compared to another:

So if you had 14 green frosted cupcakes and 8 blue frosted cupcakes what is the ratio of total frosted cupcakes to blue cupcakes:

the answer would be 22:8

Because you are trying to compare the total number of cupcakes to the blue cupcakes.

So back to your equation it wants to know the ratio between empty spots and the total number of parking spaces

Since we know that 63 of the spots have cars and 18 spots are empty we are going to add 63 and 18 together to get the total amount of parking spaces:

18 + 63 = 81

And since they want to know the empty spots compared to the total number of parking spaces we are going to be putting 18:81.
