30x+18y=486 solve for y and x

Answers

Answer 1

you can't solve for an exact answer for both x and y since there would be two solutions, think of this as a linear equation
30x+18y=486-30x
-30x
18y=486-30x
/18. /18
y=27-5x/3

30x+18y=486
-18y. -18y
30x=486-18y/30
/30.
x=81/5-3y/5

Amanda buys 4 tickets to the baseball game for $24 each. Which equation

shows the closest estimate of the total amount Amanda spends?

Which equation shows the closest estimate of the total amount Amanda spends

Answers

Answer:

$96

Step-by-step explanation:

Given that,

The total number of tickets = 4

Cost of each baseball = $24

We need to find the equation that shows the closest estimate of the total amount Amanda spends.

Total cost = No. of tickets × Cost of each baseball

= 4×24

= $96

Hence, the total cost is $96.

The soccer team is planning to sell health bars for a fundraiser. The prices of purchasing health bars from two different companies are represented by the system of equations shown, where x is the number of bars purchased and y is the total cost in dollars. Company A: y=0.75x Company B: y=10+0.50x How many bars would the team need to purchase from each company in order for the total cost to be equal?

Answers

Answer:

40 bars

Step-by-step explanation:

Where x = Number of bars purchased by each team

We solve this question by equating both Equations from Company A to Company B

Company A = Company B

0.75x = 10 + 0.50x

Collect like terms

0.75x - 0.50x = 10

0.25x = 10

x = 10/0.25

x = 40 bars

Hence, each team need to purchase 40 bars from each company

Complete the pairs of corresponding parts if △RST ≅ △TXY.

∠STR =
∠ XYT

∠ XTY

Answers

Answer:

∠STR is associated with ∠ XYT

Therefore, we conclude that:

∠STR = ∠ XYT

Step-by-step explanation:

Given

△RST ≅ △TXY

To determine:

∠STR = ?

△RST ≅ △TXY

So the triangles △RST and △TXY are congruent to each other.

We know that congruent triangles have equal corresponding parts.

Please check the attached graph.

From the graph, it is clear that:

∠STR is associated with ∠ XYT

∠STR = ∠ XYT

Therefore, we conclude that:

15 points to whoever answers correctly and brainliest!

Help! I need some explanation here!

Answers

Answer:

So its is pretty straight forward (answer at the bottom)

First of all 2 sides of a parrleogram are the dame and the other 2 are different from the first but the opposites are the same

So lets start with The distance from home to bank

x+9 is the distance since its the opposite

Now the other side is 2x+1

The third side is x+9

the fourth side is x+5, it is different from 2x+1 but its just written differently.

Now add them all up

2x+1+x+9+x+5+x+9=

5x+24

So the amount fo meters are 5x+24

The distance covered by Amaia is 5x+24 meters.

What is a parallelogram?

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

Given that, Amaia walks out and covers a distance in a shape of parallelogram,

Therefore, the opposite sides will be equal,

To find the distance covered we will find the perimeter of the parallelogrammical way,

P = x+9+x+9+x+5+2x+1

P = 5x+24

Hence, the distance covered by Amaia is 5x+24 meters.
