divide both sides by -4

therefore the answer is 2.5

Answer:

5 L

Step-by-step explanation:

As given in question,

1 L can fill 4.2 cups.

So, 1 cup can hold [tex]\frac{1}{4.2}[/tex] L of fluid.

Therefore,

21 cups can hold = [tex]\frac{1}{4.2}[/tex] × 21

                            = 5 L

So, there is 5 L of fluid in 21 cups.

Answer:

52 should be the Answer

Answer:

52cm

Step-by-step explanation:

Erm its just 13 x 4...

Step-by-step explanation:

100 / 2 (1500/5 (6 + (21 + 7 - 24)))

= 100 / 2 (1500/5 (6 + (28 - 24)))

= 100 / 2 (1500/5 (6 + (4)))

= 100 / 2 (1500/5 (10))

= 100 / 2 (300 (10))

= 100 / 2 (3000)

= 50 (3000)

= 150000

Rule: BODMAS (Brackets first so if there's bracket in bracket solve the bracket in the brackets first)

if left + - x /, solve x and / first from left to right then when there's + - left solve everything from left to right

Answer:

The correct option is;

D. When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent

Step-by-step explanation:

In the proof to show that the sum of the angles in a triangle = 180°, we have;

For a triangle located between two parallel lines, such that the base of the triangle coincides with one of the parallel lines, we have;

The angle formed by one of the base angles and the adjacent side of the extension = 180° by the sum of angles on a straight line

From the attached diagram of a triangle between two parallel lines, we have;

∠e + ∠b = 180° by the sum of angles on a straight line postulate

∠e = ∠a + ∠d by alternate interior angles postulate

∠c = ∠d by alternate interior angles postulate

∴ ∠e = ∠a + ∠c by substitution property

∴ ∠e + ∠b = ∠a + ∠c + ∠b  = 180° by substitution property

Therefore, the sum of the interior angles of a triangle, ∠a + ∠c + ∠b  = 180°.

Answer:

Step-by-step explanation:

y =  3x - 4

x = 0,  y = 3*0 - 4

          y = -4

(0 , -4)

x = 1 ,    y = 3*1 - 4

            y = 3 - 4

            y = -1

(1 , -1)

x = 2  , y = 3*2 - 4

           y = 6 - 4

           y = 2

(2 , 2)

Now mark these points (0 , -4) , (1 , -1) & (2 , 2) in the graph and join the points

Answer:

for Question 1 the answer will be 450 cuz 900/2 is 450!

for the next one it would be -9 cuz -27/3 is -9!

hopefully this helped!

Answer:

x ≤ 75

Step-by-step explanation:

The computation of the inequality function is as follows:

Let us assume the remaining time left for other drills be x

Given that the team spends 20 minutes for running laps

And minimum of 15 minutes for discussing plays

Also practicing for last one hour and 45 minutes

Now as we know that

1 hour = 60 minutes

So total minutes would be

= 60 + 45

= 105 minutes

Total minutes spend by the team is

= 20 + 15

= 35 minutes

So now the remaining time left is

x ≤ 105 - 35

x ≤ 75

Answer:

4 1/2

Step-by-step explanation:

Answer:

Convert 1 1/2 into a regular fraction

Because the following quantity, 1 1/2 is a  mixed fraction

1 1/2 = 3/2

According to the question

The recipe for one bath call for 3/2 cups of flour

1 batch needs 3/2 cups of flour

Multiply 3 to both of the sides

3x1 batch needs 3 times 3/2 cups of flour

3 batch would need 4 1/2

Answer:

y=4(3)^x

Step-by-step explanation:

The exponential function, that goes through points (0,4) and (6, 2916) is y = 4(3)ˣ

An exponential function is a mathematical function used to calculate the exponential growth or decay of a given set of data.

Given that, a graph of an exponential function is passing through, (0,4) and (6, 2916)

The exponential form of an equation is given by =

y = abˣ

Where, a is the y-intercept,

a = 4 here,

y = 4bˣ

Now substitute 6 for x and 2916 for y,

2916 = 4(b)⁶

b⁶ = 729

b = 3

Therefore,

y = 4(3)ˣ

Hence, the exponential function, that goes through points (0,4) and (6, 2916) is y = 4(3)ˣ

Answer:

x column- 1.25, 7.5, 45.

y column- 5, 30, 180.

Step-by-step explanation:

Okay, to start off, we need to find how 1.25 got to 5. If we divide it, we get 4. So we go to 7.5 and multiply it by 4, since that seems to be the relationship between x and y. 7.5x4=30, which is an answer. So the second spot in the y column is where 30 goes. Now we figure out the relationship between the two numbers in the x column so we can figure out the missing one. When you divide 7.5 by 1.25, you get 6. So, if 1.25x6 makes the next number in the x column, 7.5x6 should make the missing number. 7.5x6 is 45, so the missing number in the x column is 45. Now we go back and multiply 45 by 4, which gets us 180.
