Answer 1

Answer: $b\ \ \ \rightarrow\ \ \ the\ number\ of\ blue\ marbles\ng\ \ \ \rightarrow\ \ \ the\ number\ of\ green\ marbles\n\nb+g \geq 54\ \ \ and\ \ \ b=2g\n\n2g+g \geq 54\ \ \ \Leftrightarrow\ \ \ 3g \geq 54\ \ \ \Leftrightarrow\ \ \ g \geq 18\n\nAns.\ At\ least\ 18\ green\ marbles.$

Answer 2

Answer: If we have twice as many blue marbles as green, we have 3 parts; 2 parts blue and 1 part greens. Therefore, 1/3 of the marbles are green

54/3=18
At least 18 of the marbles are green

Solve for the variable in 7 ∕28 = 25∕ x A. 20 B. 100 C. 4 D. 5

Answers

The solution to the equation 7/28 = 25/x is x = 100.

What is the solution to the equation?

Given the equation in the question:

7/28 = 25/x

To solve for the variable x in the equation 7/28 = 25/x, first, we cross multiply.

7/28 = 25/x

Cross-multiplying, i.e multiplying the numerator of the first fraction with the denominator of the second fraction and vice versa:

Hence:

7 × x = 28 × 25

7x = 700

Now, isolate x by dividing both sides by 7:

7x/7 = 700/7

x = 700/7

x = 100

Therefore, x has a value of 100.

Option B) 100 is the correct answer.

Solve by the multiplication of equality 5/49*x = 20/7

Answers

5/49(x) = 20/7
5x/49 = 20/7
5x/49 × 49  = 20/7 × 49
5x  = 140
5x / 5  = 140 / 5
x = 28

Liliana used 444 dark power crystals to raise 141414 zombie soldiers. She wants to know how many zombie soldiers (z)(z)left parenthesis, z, right parenthesis she can raise with 101010 dark power crystals. How many zombie soldiers can Liliana raise with 101010 power crystals?

Answers

Question is bit incorrect, Correct question is given below.

Liliana used 4 dark power crystals to raise 14 zombie soldiers. She wants to know how many zombie soldiers (z) she can raise with 10 dark power crystals. How many zombie soldiers can Liliana raise with 10 power crystals?

Answer:

Liliana can raise 35 zombie soldiers.

Step-by-step explanation:

Let the number of zombie soldiers raised by 10 dark power crystals be 'z'.

Zombie raised by 4 power crystals = 14

Since the number of zombie and power crystals are in direct proportion.

Therefore, we get

$(z)/(10)=(14)/(4)$

Multiply 10 on both the sides, we get

$z=(14)/(4)* 10 = 35$

Hence, Liliana can raise 35 zombie soldiers.

Answer:

35 Zombie Soldiers

Step-by-step explanation:

The numbers are -7 and 5. It can be expressed as this (x-7)(x+5)=0 if thats what you're doing.

-7 and 5 because when adding and subtracting a negative and a positive is negative same for multiplying

whats the equation? but when ever you see f( ), what ever is in the parenthesis just plug into x

f(x) = x² - 4x + 3
f(-1) = (-1)² - 4(-1) + 3
f(-1) = 1 + 4 + 3
f(-1) = 5 + 3
f(-1) = 8

Which measurement is not equivalent to the others?2 quart
8 cups
72 fl. oz.
4 pints

Answers

If you would like to know which measurement is not equivalent to the others, you can calculate this using the following steps:

1 quart = 4 cups = 2 pints = 32 fl. oz.

2 quarts = 2 * 4 cups = 8 cups
2 quarts = 2 * 2 pints = 4 pints
2 quarts = 2 * 32 fl. oz. = 64 fl. oz.

Not equivalent: 72 fl. oz.
