You are on a roller coaster that begins 1/5 mile above ground. The roller coaster descends 1/2 mile. What is the roller coaster's new location after descending?

Answer:

D - 320

Step-by-step explanation:

You divide 48 by 15% and it equals 320 which is the starting value. To check your answer you take 15% out of 320 which gives you 48. Letter C is incorrect because 15% of 150 is 22.5. A and B are not correct because A is lower than the amount spent and there is no way that B would work because 15% of 55.20 is 8.28. Good luck with your math test!

Answer:

4 * 2y + 4 * 1

4(2y + 1)

Distributive property

Step-by-step explanation:

8y + 4

We can factor out a 4 out of both as both are divisible by 4

8y / 4 = 2y

4 / 4 = 1

So 8y + 4 is the same as saying 4 * 2y + 4 * 1

This can be written as 4(2y + 1) which is written using the distributive property

Answer:

-1/2x-2

Step-by-step explanation:

Distribute the negative sign from the right side to make the equation positive

1/4x - 7 + (-1)(3/4x) + (-1)(-5)

(basically multiplying -1 to 3/4x and -5 to eliminate it)

1/4x - 7 + -3/4x+ 5

Make the equation similar

(1/4x + -3/4x) + (-7 + 5)

combine like terms

1/4x + -3/4x = -2/4x --> Simplifies to -1/2x

Do the other integers

-7 + 5 = -2

Put it together

-1/2x-2

Answer:

65.25

Step-by-step explanation:

52.20 is the total for 20 gallons of gas

we divide 52.20 by 20 to find out the price per gallon.

52.20/20= 2.61 per gallon

for 25 gallons --> 2.61 x 25 = 65.25

Answer: 4.416 (the 6 should have a line on top to show it goes on)

Step-by-step explanation:

x/5+6 =>  expression means “6 more than the quotient of a number and 5”.

Option B is correct.

Here,

The expression that means "6 more than the quotient of a number and 5" can be written as:

(x / 5) + 6

In this expression, "x" represents the unknown number.

Let's break down the expression and explain it step by step:

(x / 5):

This part of the expression represents the quotient of "x" and 5.

It means that we divide "x" by 5.

(x / 5) + 6:

his means we take the quotient obtained in step 1 and add 6 to it.

It represents "6 more than the quotient of a number and 5."

Hence, x/5+6 =>  expression means “6 more than the quotient of a number and 5”.

Option B is correct.

Answer:

Problem 3: Just 33 draw 4 boxes of 11 and one with 11

Problem 4: 30
Problem 5: Naomi

Step-by-step explanation:

For problem three since you are multiplying the same equation by 4 its basically (2+9)+3(2+9) so you can just cancel out the 2+9 from both and you are left with 3(2+9) which is just 33

For problem 4 100-(12x4)=52 and 10+(3x4) = 22 and when you subtract the two (52-22) you get 30

For problem 5 you get 18 with your equation and so since Carlos' equation gets 9 and Miranda gets 24 and Will gets 35 the only one left is Naomi which also gets 18 just like you.

The expression that represents the number of tulips Pia planted is option A. x/2 + 4.

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given that,

Number of daisies planted is represented by x.

Number of tulips planted is 4 more than half the number of daisies.

Half the number of daisies is x/2.

4 more than half the number of daisies is x/2 + 4.

Hence the number of tulips planted is given by the expression x/2 + 4.

Step-by-step explanation:

FOIL method

x^2+6x-27=0

Find the common numbers that multiply to 27 that will also equal 6.

(27x6) or (9x3)

the 6 is positive while 27 is negative so you need to use a + and - in the parenthesis.

then FOIL them

(x+9)(x-3)

FIRST:  x*x=x^2

OUTSIDE: x*-3=-3x

INNER: 9*x=9x

LAST: +9*-3=-27

x^2(-3x9x)-27

x^2+6x-27

now that the equation matches you solve for x.

(x+9)=0  x=-9

(x-3)=0   x=3

Answer:

15/6

Step-by-step explanation:

(20/9) ft of the hole is elevated after the shrub was placed.

Given is that Malik digs a hole at a rate of 2/3 feet every 15 minutes. After digging for 60 minutes, Malik places a shrub in the hole that fills exactly 5/6 feet of the hole.

In 15 minutes, the depth of hole digged is (2/3) feet.

In 1 minute, the depth of hole digged is {(2/3)/15} feet.

In 60 minutes, the depth of hole digged will be {(2/3)/15} x 60 = 8/3 ft.

The hole filled after placing the shrub will be -

(5/6) x (8/3)

5/6 x 8/3

5/3 x 4/3

20/9

Therefore, the (20/9) ft of the hole is elevated after the shrub was placed.
