 1) The answer would be $2. You can solve this problem by setting an equation: 20= 7x+6. Subtract 6 from both sides and you get 14= 7x. After that, divide both sides by 7. 14 divided by 7 is two. The answer is 2.


2) The answer would be 29. You can answer this question by setting up the following equation:  x+x+2+x+4=93. For instance, you know that x is an odd number (example lets say its the number 1). The next consecutive ODD number would have to be 3 (following the example given), which can be represented by x+2 (1+2=3). Now, knowing this, the third number can be represented by the expression x+4 (1+4=5, which makes sense as the order of the numbers would now be 1,3,5- consecutive odd numbers). Apply this to the question:   x+x+2+x+4= 93 then becomes 3x+6 after combining like terms. This leaves you with 3x+6=93. Subtract 6 from both sides: 3x=87. Divide both sides by 3: x=29 (the smallest number as the other numbers would be 31 and 33 which you get by plugging in to x+2 and x+4). Finally, you can check your answer by adding all the numbers :-)

3) 8 notepads. The question states that Danielle had $35 and bought 1 magazine (worth $3) and some notepads (each worth $4). You can solve this question by setting up the following equation: 35= 3+4x. Subtract both sides by 3 and you get 32=4x. Divide both sides by 4: 8=x.

4) $20
5) $12
6) 4 candy bars
7) $8
8) 5 hours

Elena is trying to figure out how many movies she can download to her hard drive. The hard drive is supposed to hold 500 gigabyt
soldi70 [24.7K]

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Maximum capacity of hard drive = 500 GB

Space used up = 58 GB

Size per movie = 8GB

Number of movies = x

1)

[(Number of movies * size per movie) + used up space] should be less than or equal to the maximum capacity to f the drive.

From Elena's inequality, the total space taken up by movies + used up space is greater than total capacity of hard drive.

That is ;

[(8x + 58 ≤ 500

8x ≤ 500 - 58

8x ≤ 442

x ≤ 442 / 8

x ≤ 55.25

The maximum number of movies Elena can download is 55

Varvara68 [4.7K]

Answer:

The answer to your question is: Ф = 43.95°

Step-by-step explanation:

Data

length = 18 ft

distance bottom to is 13 ft

x = angle = ?

Formula

cos Ф = opposite side / hypotenuse  

Process

cos Ф = 13 ft / 18 ft                   substitution

cos Ф = 0.72                            simplify

Ф = cos⁻¹ (0.72)

Ф = 43.95°                                result

4. Find the value of n that makes this equation true. (Use
andreyandreev [35.5K]

Answer:

n=4

Step-by-step explanation:

We start off with 3.2n + 13.3 = 26.1.

We need to get n by itself.

Subtract 13.3 from both sides.

3.2n+13.3-13.3=26.1-13.3

26.1-13.3=12.8

We end up with: 3.2n=12.8

Divide 3.2 on both sides to get n by itself.

\frac{3.2n}{3.2} =\frac{12.8}{3.2}\\ n=4
