For this case, from the diagram we can conclude the following results according to the surveys:

For Dogs:
Dogs = 24 + 31 = 55
No dogs = 10
Total = 65

For the cats:
Cats = 10 + 31 = 41
No cats = 24
Total = 65

Solve the following equations: a) 4b = 20

Sidana [21]

B=5
You need to get b by itself on the left side. 4b is multiplying 4 to b. You need to the opposite when you want the variable by itself. You would divide 4 to each side. 4 cancels out on the b so it turns into b. Then 4 divided by 20 is 5. B=5

The gardening club at school is growing vegetables. The club has 300 square feet of planting beds. Cucumber plants require 6 squ

The question doesn't ask anything in particular, I will show the set of inequalities defined in the problem.

Answer:

System of inequalities:

$6c+4t\leq 300$

$c>0\\t > 0\\c+t\geq 60$

Step-by-step explanation:

Inequalities

The express relations between expressions with a sign other than the equal sign. Common relationals are 'less than', 'greater than', 'not equal to', and many others.

The gardening club at school has 300 square feet of planting beds to plant cucumber and tomato. Each cucumber plant requires 6 square feet of growing space and each tomato plant requires 4 square feet of growing space. We know the total area cannot exceed 300 square feet, so

$6c+4t\leq 300$

Being c and t the number of cucumber and tomato plants respectively.

We also know the students want to plant some of each type of plant and have at least 60 plants. This lead us to more conditions

$c>0\\t > 0\\c+t\geq 60$

Note: The set of inequalities shown is not enough to uniquely solve the problem. We need something to maximize or minimize to optimize c and t

Answer:

67°F

Step-by-step explanation:

The mean is another way to say average.

To find the average: you have to add up all of the temperatures, then divide by how many numbers (in this case, time slots) are there.

58°F + 60°F + 61°F + 67°F + 69°F + 73°F + 74°F + 74°F = 536°F

536°F ÷ 8 (total number of time slots) = 67°F
