Answer:

  3.  -2

  4.  12

  5.  -4

Step-by-step explanation:

For all problems, let n represent "a number." You will note that when we specify an operation to be done on the equation, it is done to <em>both sides of the equation</em>.

__

3. 5n +(-3) = -13

  5n = -10 . . . . . . add 3

  n = -2 . . . . . . . . divide by 5

The number is -2.

__

4. (n/2) -7 = -1

  n/2 = 6 . . . . . . . add 7

  n = 12 . . . . . . . . multiply by 2

The number is 12.

__

5. 2n -1 = -9

  2n = -8 . . . . . add 1

  n = -4 . . . . . . divide by 2

The number is -4.

A bicycle has a speed of 6 m/s. What is its speed in km/h?<br> (1 km=1000 m)<br> (1 h = 3600 s)
Tems11 [23]

answer:

m/s --- km/h = \frac{1000}{3600}

km/h= \frac{5}{18}

6m/s= \frac{6*5}{18}

6m/s= 1.66 km/h

6k ÷ 7 = -3<br> Solve for k
fomenos

Answer:

k = -3.5

Step-by-step explanation:

6k ÷ 7 = -3

Multiply 7 to both sides

6k = -21

Divide both sides by 6

6k/6 = -21/6

k = -3.5

To check if the answer is correct or not, you can always plug in -3.5 for k in the equation.

6(-3.5) ÷ 7 = -3

-21 ÷ 7 = -3

-3 = -3

-3 equals -3 so it is correct that k = -3.5

Car rentals involve a $130 flat fee and an additional cost of $31.67 a day. what is the maximum number of days you can rent a ca
Vladimir79 [104]
Represent the number of days by x. With this representation, the variable cost of the rental is 31.67x. The total cost is the sum of the fixed and variable costs. This value should not be more than $500. The equation below shows the relationship.
                                          130 + 31.67x ≤ 500

Solving for x gives x ≤ 11.68
Thus, the maximum number of days to rent the car is only 11 days.

The line plot shows the growth, In Inches, of Isabella's plant over 13 days. Growth of Isabella's Plant What is the total growth
mart [117]

Line plots are used to display data elements using markers

The total growth, in inches, of Isabella's plant is 4\frac{1}2 inches

<h3>How to determine the total growth</h3>

From the line plot, the total growth can be represented as:

Total = \frac 18 * 4 + \frac 28 * 2 + \frac 38 * 3 + \frac 48 * 1 + \frac 58 * 3

Evaluate the products

Total = \frac 48+ \frac 48 + \frac 98 + \frac 48 + \frac {15}8

Evaluate the sum

Total = \frac{4+4+9+4+15}8

Evaluate the numerator

Total = \frac{36}8

Evaluate the quotient

Total = 4\frac{1}2

Hence, the total growth, in inches, of Isabella's plant is 4\frac{1}2 inches
