Priya has $30 to spend at the school festival. Admission is $4 and each ride ticket is $2. Which inequality represents the greatest number of ride tickets she can buy2n+4<30
2n+3>30
2n+4≤30
2n+4≥30

Answers

Answer 1
Answer:

Answer:

4 + 2n ≤ 30

Step-by-step explanation:

  • Priya has $30 to spend at the school festival.
  • Each ride ticket costs $2, and the admission is $4.
  • So, the cost of n ride tickets would be 2n dollars.
  • The total cost of the admission and ride tickets would be the sum of the admission and the cost of ride tickets: 4 + 2n.
  • We want to find an inequality that ensures the total cost does not exceed $30.
  • In other words, we want 4 + 2n to be less than or equal to 30.

Now, let's represent this in an inequality:

4 + 2n ≤ 30

Aseem and Stana are building model cars. stanas car is 5 less than 2 times the length of Aseem's car. The sum of the lengths of both cars is 20. write an equation to determine the lengths of Aseem's and Stana's cars

Answers

Answer:

Aseem’s : 8.3, Stana’s : 11.6

Step-by-step explanation:

Aseem: x

Stana: 2x-5

X+2x-5=20

3x=25

X = 8.3

Final answer:

The length of Aseem's car is approximately 8.33 and the length of Stana's car is approximately 11.66.

Explanation:

Let's define the length of Aseem's car as x. Stana's car is 5 less than 2 times the length of Aseem's car, so the length of Stana's car can be represented as 2x - 5. The sum of the lengths of both cars is 20, so we can set up the equation x + (2x - 5) = 20. Solving this equation will give us the lengths of Aseem's and Stana's cars.

Combining like terms, we get 3x - 5 = 20. Adding 5 to both sides of the equation, we have 3x = 25. Finally, by dividing both sides by 3, we find that x = 8.33.

The length of Aseem's car is approximately 8.33 and the length of Stana's car is approximately 2(8.33) - 5 = 11.66.

If three bags of birdseed cost $14.16, how much will 14 bags cost? A. $33.71
B. $66.08
C. $30.34
D. $70.80

Answers

All the information's required for solving this problem is already given in the question.
The cost of 3 bags of birdseed = 14.16 dollars
Then
The cost of 1 bag of birdseed = (14.16/3) dollars
So
The cost of 14 bags of birdseed = (14.16/3) * 14 dollars
                                                    = 198.24/3 dollars
                                                    = 66.08 dollars
So from the above deduction we can see that the correct option is option "B". The cost of 14 bags of birdseed is $66.08. I hope the procedure is clear enough for you to understand.
the correct cost would have to be b. $66.08. You have to divide $14.16 by 3, then multiply by 14.

Write an expression that simplifies to 160 using the commutative and associative properties

Answers

Answer:

Let's say we have an expression x * y + z * w, where x, y, z and w are numbers.

We can use the commutative property to change the order of the summands:

x * y + z * w = y * x + w * z = (y + z) * x + w

Since we have a sum of two products, we can use the associative property to combine them:

(y + w) * (x + 15) = 160

By dividing both sides of the equation by 2, we get:

(y + w) / 2 * (x + 15) / 2 = 80

We can then simplify this expression using the distributive property:

(y / 2) + (w / 2) * (x / 2) + (15 / 2)

Since the numbers are all positive, we can cancel out the halves on the left, and combine the remaining terms:

y / 2 + (w / 2) * x + 15 / 2 = 80

Finally, we can simplify this expression by dividing both sides of the equation by the constant fraction:

y / 2 + (w / 2) * x + 15 / 2 = 80

(y / 2) + (w / 2) * (x / 2) + (15 / 2) = 80

Simplifying this expression, we get y / 2 + (w / 2) * x / 2 + 15 / 2 = 40.

By simplifying the last term further, we get:

y / 2 + (w / 2) * x / 2 + 7.5 = 40

Therefore, the equation that simplifies to 160 is this one:

y / 2 + (w / 2) * x / 2 + 7.5

Yes they should reach the 8.1 mile marker by noon

if they kept walking for a full 2 hours they would reach the 8.4 mile marker

Which number in the monomial 215x18y3z21 needs to be changed to make it a perfect cube?3
18
21
215

Answers

remember
xyz=(x)(y)(z)
if x and y and z are all perfect cubes, xyz is also a perfect cube

remmeber
(x^n)^m=x^(mn)
so if it is perfect cube it can be factored into
(x^n)^3, such taht n is a whole number
basiclaly, see if the expoent is divisble by 3

all of them should be perfect cubes

215x^18y^3z^21

split them up to see which ones need changing

215=5*43, not  a perfect cube
could be changed to 6^3, which is 216

x^18=(x^6)^3

y^3=y^3
z^21=(z^7)^3

the 215 needs to be changed
