What is an equation?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.

MR. ARCEO TAKES A TAXI FROM THE AIRPORT TO A HOTEL. THE TAXI CHARGES $2.50 INITIAL CHARGE PLUS $2.65 PER MILE. WHICH EQUATION CAN BE USED TO FIND Y, THE TOTAL COST OF THE TRIP, IF X REPRESENTS THE NUMBER OF MILES OF THE TRIP?
Answers
step by step explanation:
2.65 is how much for each mile, and the variable, x, represents the number of miles of the trip. so, we would do 2.65x to find out how much money you have to pay for the amounts of mile.
next, you would have to add the initial fee, which is 2.50. so 2.65x+2.50.
lastly, y represents the total cost of the trip. so, 2.65x + 2.50 = y

Answers
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.
Hope this helped you!!!

The Mackinac Bridge in Michigan is the third-longest suspension bridge in the United States.
a. How high above the water is the roadway in meters? Round to the nearest hundredth.
The roadway is about ____ meters above the water.
Question 2
b. The bridge has a length of 26,372 feet. What is the length in kilometers? Round to the nearest hundredth.
The length of the bridge is about ____ kilometers.
Answers
b:8.04 km
The roadway is about 60.66 meters above the water.
The length of the bridge is about 8.04 kilometers.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 hour = 60 minutes
1 km = 1000 m
We have,
The length of the roadway above the water = 199 ft
1 ft = 0.3048 m
Multiply 199 on both sides.
199 ft = 60.66 m
The bridge has a length of 26,372 feet.
1 ft = 0.0003048
Multiply 26372 on both sides.
26372 ft = 26372 x 0.0003048
26372 ft = 8.04 km
Thus,
The roadway in meters is about 60.66 meters above the water.
The length of the bridge in km is about 8.04 kilometers.

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

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=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=30×19+10
y=580≠520
Hence, option: D is incorrect.
