Answer:

Hello.

The answer is $6 each item.

Step-by-step explanation:

If all of the items are the same price, then we have a total of 7 items ( 3 keyboards + 4 mic = 7 items).

So at the end is: 7 items ÷ $42 = $6.

Malia is planting tomato and pepper plants in her garden each tomato plant t requires 6 square feet and each pepper plant p requ
MAVERICK [17]

Answer:

6 t + 4  p   ≤  150   is the required inequality.

Step-by-step explanation:

Here, the area required for 1 tomato plant = 6 sq ft

So, the area required to plant t tomato plants  

= t x ( Area required by 1  tomato plant)   = t x ( 6 sq ft)  = 6 t

the area required for 1 pepper plant = 4 sq ft

So, the area required to plant p  pepper plants  

= p x ( Area required by 1  pepper plant)   = p x ( 4 sq ft)  = 4 p

Now, total area of the garden = 150 Sq ft.

Also, area of p pepper pants + t tomato plants =   (6 t +  4 p) sq ft

So, now according to the question:

Total area of both plants ≤ Total area of the garden

⇒ (6 t +  4 p) sq ft   ≤  150 sq ft

or, 6 t + 4  p   ≤  150   is the required inequality.

Explain why 8 x ¾ is the same as adding ¾ + ¾ + ¾ + ¾ + ¾
Mekhanik [1.2K]

8 x ¾ is the same as adding ¾ + ¾ + ¾ + ¾ + ¾

because, when you are adding 3/4

8 times, you are 3/4 plus itself,

eight times,

so you are doing 3/4*8

A science test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5 points. If x is
mamaluj [8]

Answer: The test contains 10 three-point questions and 14 five-point questions.

Step-by-step explanation:

Let x represent the number of 3-point questions.

Let y represent the number of 5-point questions.

The maths test consists of 24 questions. This means that

x + y = 24

Each question is worth either 3 points or 5 and the test is worth 100 points. This means that

3x + 5y = 100 - - - - - - - - - - -1

Substituting x = 24 - y into equation 1, it becomes

3(24 - y) + 5y = 100

72 - 3y + 5y = 100

- 3y + 5y = 100 - 72

2y = 28

y = 28/2 = 14

Substituting y = 14 into x = 24 - y , it becomes

x = 24 - 14 = 10
