Using the numbers -4, 10, 8, 2, -3, -5, write down two expressions that equal 6. You can use any relevant operation. You have to use more than 2 integers in each calculation.

Answers

Answer:

[tex] \sf \Bigg[ \frac{ ( - 4 \times ( - 3)) }{2} \Bigg] \: and \: \Bigg[ \frac{ - ( - 5 \times 8)}{10} + 2 \Bigg][/tex]

Step-by-step explanation:

Given:

[tex]The \: numbers \rightarrow -4, 10, 8, 2, -3, -5[/tex]

To find:

Two expressions that equal 6 using the given numbers

Solution:

Expression first,

Using numbers -4, 2, -3,

aligning the above numbers as,

[tex] \frac{ ( - 4 \times ( - 3)) }{2}[/tex]

will out put 6.

Verification,

[tex] \frac{ ( - 4 \times ( - 3)) }{2} = \frac{12}{2} = \cancel\frac{12}{2} = 6[/tex]

Expression second,

Using numbers 10,8,2,-5

aligning the above numbers as,

[tex] \frac{ - ( - 5 \times 8)}{10} + 2[/tex]

will result 6.

Verification

[tex]\frac{ - ( - 5 \times 8)}{10} + 2 = \frac{ 40}{10} + 2 \\ \\ \frac{ - ( - 5 \times 8)}{10} + 2= 4 + 2 \\ \\\frac{ - ( - 5 \times 8)}{10} + 2 = 6[/tex]

The Rock has an 88-gallon fish tank. When it needs to be cleaned, it can be drained at a rate of 6 gallons per minute. Show all work. Complete sentence for each question.

first part: Assuming the tank was full, write a function in the form y=mx + b that represents the amount of water in the tank, Y, after X minutes. You will need to know the initial value and the rate of change.

second part: How long has the tank been draining for if it has 34 gallons left?

Answers

Answer:9 minutes

Step-by-step explanation:

1. to find how much was drained subtract how much is left from the total amount when full  88-34= 54

2. divide answer by the rate per minute  54/6

3. you have answer 9 minutes

The amount of water in the tank is given by y = -6x + 88, it would take 9 minutes for the water to remain 34 gallons.

What is an equation?

An equation is an expression that shows the relationship between two or more variables and numbers.

Let y represent the amount of water after x minutes.

The Rock has an 88-gallon fish tank which can be drained at a rate of 6 gallons per minute. Hence:

m = -6, b = 88

y = -6x + 88

For 34 gallons:

34 = -6x + 88

x = 9

Hence, the amount of water in the tank is given by y = -6x + 88, it would take 9 minutes for the water to remain 34 gallons.

THANKS! O
COMMENTS

The angle that is complementary to ∠DEF is ∠EFA.

Option C is the correct answer.

What is an angle?

The angles between two lines are the angles formed by two intersecting lines, measured in degrees or radians.

Several different types of angles can be formed between two lines, including acute angles, right angles, and obtuse angles.

We have,

Complementary angles are two angles that add up to 90 degrees.

In other words,

If angle A and angle B are complementary angles, then A + B = 90 degrees.

Now,

From the figure,

∠DEF and ∠EFA will make a 90-degree angle.

Thus,

The angle that is complementary to ∠DEF is ∠EFA.

On a map, 30 kilometers is represented by 2 centimeters.

How many kilometers would a measure of 5 centimeters on the map represent?
75 kilometers
150 centimeters
300 kilometers
70 kilometers

Answers

Answer:

75 km

Step-by-step explanation:

If 30 km is represented by 2 cm, then that means 15km is represented by 1cm.

So 5cm X 15km per cm = 75

i’m pretty sure it would be 75 km
because if you divide it 30 by 2 it is 15 which means each centimeter is 15 so 5×15 is 75.
