The number of balloons, y, was three less than two times the amount of streamers perchased, x,. If Abbie bought a combination of 9 balloons and streamers, what system of equations can represent the situation?

Answer:

Your answer is C. 26.8

Step-by-step explanation:

5 × 1.79 = 8.95

15 × 1.19 = 17.85

8.95 + 17.85 = 26.8

Answer:  C ($26.80)

Step-by-step explanation:

This is a multiplication problem.

The first 5 bags of candy cost $1.79 each, so we multiply the cost by the amount of bags that we bought for that price:

5 * 1.79 = $8.95

The rest of the bags cost $1.19 each, so we need to multiply this number by some value. To find this value, we need to know how many bags we have left. We already bought 5, and we bought a total of 20, so we need to buy:

20 - 5 = 15 bags

Multiplying the cost for the rest of the bags (1.19) by the amount of bags we need to buy still (15), we get:

15 * 1.19 = $17.85

Now we know what the cost of the first 5 bags (8.95), and we know the cost of the 15 other bags (17.85). To find the total amount of money Veronica spent, we can just add these two values together.

8.95 + 17.85 = $26.80

This total cost is shown in answer C, so that is the answer.

Answer:

No solutions

Step-by-step explanation:

3(2y + 4) = 7y + 4 - y

~Simplify both sides

6y + 12 = 6y + 4

~Subtract 12 to both sides

6y = 6y - 8

~Subtract 6y to both sides

0 = 8

Answer:

Y= 21x+10.25

Step-by-step explanation:

(1,31.25) (0,10.25)

Slope= 21

21X-0=y-10.25

Y= 21x+10.25

You show the time on the x-axes (from 0 to 35) and the distance on the y-axes (from 0 to 10).

You start at origin of coordinates. Then the graph rises linear until it reaches the point (20|3.3333...), then it is parallel to the x-axes (as he does not move) until it reaches (25|3.3333...). Then it increases again until it reaches (35|10).

Basically, it's linear all the time, while the slope of the graph varies in three different intervals. (Actually it wouldn't be linear as he doesn't move with the same speed all the time but we can't go more into detail based on the information we have, so we use average values.)

You can use the rule of three to find out how far he moves.

Answer:

B.

Step-by-step explanation:

55.5 kilometers would be 1° of the longitude measure in kilometers at 45° latitude north.

Latitudes are horizontal lines that indicate how far away from the equator a location is. Longitudes are vertical lines that represent the east and west directions relative to Greenwich, England's meridian. Cartographers, geographers, and others can pinpoint points or locations on the globe by combining latitude and longitude.

Given, At the equator, one degree of longitude is around 111 kilometers. The size of a degree fluctuates as we go north or south. since the equator is perpendicular to the pole. which is 90 degrees hence it's asking distance of 45 therefore from the proportionality concept in a right angle triangle. the distance at 1 is at 45 latitudes is 111/2 or 55.5.

Therefore, At 45° latitude north, 55.5 kilometers would represent 1° of the longitude measurement in kilometers.

Answer:

f(17) = $15.75

The amount it takes for a trip of 17 miles is $15.75

Step-by-step explanation:

Here, we want to calculate f(17)

The equation is given as;

y = 0.75x + 3

For f(17), substitute x for 17

y = 0.75(17) + 3

y = 12.75 + 3

y = $15.75

What f(17) means is that the ride was for 17 miles

$15.75 is for a trip of 17 miles

Answer:Yes it is proportional because w=kp k=paper weight which is constant. The relationship between the weight of a stack of standard 8.5x11 copier paper vs number of sheets of paper is proportional.

Step-by-step explanation:

Answer: Yes it is a direct proportional relationship

================================================

Explanation:

The equation is in the form y = kx, where

x = number of sheets of paper

k = weight of 1 sheet of paper

y = weight of all the x sheets of paper

x is some nonnegative whole number. The values of y and k are some nonnegative real numbers (aka any decimal values).

Note how if we had x = 0 pieces of paper, then y = 0 is the weight. So no paper leads to no weight. This visually is shown by the line y = kx going through the origin. All direct proportion equations go through the origin.

Each time we add a sheet of paper, we add on k ounces or k grams, or whatever units you're working with. The amount is constant assuming you are dealing with the same type of paper. Comparing y = kx with y = mx+b, we see that k plays the role of the slope or rate of change.
