name three solutions of the inequality of z < 4

Answer:

2 ducks and 8 goats

Step-by-step explanation:

let goat be g

let duck be d

d + g = 10

ducks have 2 legs, 2d

goats have 4 legs, 4g

2d + 4g = 36

making d the subject in the first equation;

d = 10 - g

put in second equation

2(10 - g) + 4g = 36

20 -2g + 4g = 36

2g = 36 - 20

2g = 16

g = 8

if g is 8

d = 10 - 8

d = 2

Answer:

30 cm

Step-by-step explanation:

set up a proportion of insect height over its shadow equals flower height over its shadow, then cross-multiply

1/.5 = x/15

.5x = 15

x = 30

If you mean 4x6, then it would be C and D.

A would be 4^6 and B would be 6^4, both of which we don't want.

Answer:

3 1/3 metric tons per hour

Step-by-step explanation:

To find the unit rate, divide 3 3/4 metric tons by 1 1/8 hours (notice that the correct format is 3 3/4, not 3/3/4).

 3 3/4 metric tons       3.75 metric tons

---------------------------- = --------------------------

        1 1/8 hours                1.125 hours

It's easier to deal with decimal fractions here than with proper fractions.

The unit rate then comes out to be 3.75/1.125 metric tons per hour, or

3.33333 metric tons per hour, or   3 1/3 metric tons per hour

Answer:

x = 128

Step-by-step explanation:

Adjacent angles - Angles right next to each other. They share a common vertex

Vertical angles - angles that are vertically aligned with each other.

The angle that has a measure of 128 degrees and x are vertical angles

If you didn't know vertical angles are congruent so because one angle equals 128 degrees the other equals 128 degrees

x = 128

The given angle are the vertical angles and the measure of the angle x is 128°.

Given that,
To specify whether the angles are adjacent or vertical. Then find the value of x.

orientation of one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

Here,
By the observation, angle x and 128° are the vertical angles and by the property of the intersection of the line both are equal angles so the measure of angle x is also equal to 128°.

Thus, the given angle is the vertical angle and the measure of the angle x is 128°.

Answer:

Multiply the first equation by 2

2(2x+y=5) to get 4x + 2y = 10

add the second equation 3x-2y=4

4x + 3x + 2y + -2y = 10 + 4

7x = 14

x = 2

...

Multiply the first equation by 3 and the second equation by -2 then add

3(2x+y=5) to get 6x + 3y = 15

-2(3x-2y=4) to get -6x + 4y = -8

add them

6x + -6x + 3y + 4y = 15 + -8

7y = 7

y = 1

...

x = 2 , y = 1

(2, 1) is the solution

Answer:

Kindly check explanation

Step-by-step explanation:

Given the Equation :

(5/8)m = 25

The first step to take with this kind of equation is to multiply both sides by the denominator, 8

5m/8 * 8 = 25 *8

5m = 200

Then, we can divide both sides by 5 in other to isolate m

5m / 5 = 200 / 5

m = 40

Answer: m+40

Step-by-step explanation:

Given the Equation :

(5/8)m = 25

Answer:

A proportion is a comparison of two numbers that each represent the parts of a whole. Essentially, a proportion says that two fractions are the same, even if the amount is different. For example, 1/2 of 10 marbles is the same proportion as 1/2 of 50 marbles.

Step-by-step explanation:

Answer:

Adding 12 to the circle area is equal to the square area.

Or

s2 = 12 + A

Where

s = side of square

A = area of circle

So

s2 = 12 + 36

s2 = 48

Solve this for s to get the side length

Answer:

Step-by-step explanation:

Plugin y = 7 in the expression

y - 8 ÷ 4 = 7 - 8÷ 4      { here division has to be done first as per PEDMAS}

              = 7 - 2

              = 5

Step-by-step explanation:

14. K' = x + a, y + b

= -1 + 2, 6 + 3

K' = 1, 9

K" = (x, y) → (-x, y)

= (1, 9) → (-1, 9)

K" = -1, 9

15. D. Octagon

Since it has 8 angles, of 360 ° is divided by 8 angles, then each corner has an angle of 45 °

16. P' = x + a, y + b

= -2 + 6, 4 + 5

P' = 4, 9

17. H' = x + a, y + b

= 5 + 10, 4 + (-11)

= 15, -7

18. A (6, -1)

A' = (x, y) → (x, -y)

= (6, -1) → (6, -(-1)

= 6, 1

19. J' = x + a, y + b

= -2 + (-3), 1 + (-3)

= -5, -2

J" = (x, y) → (x, -y)

= (-5, -2) → (-5, -(2))

= -5, -2
