Answer: K=m+4

Explanation: You take mikes age (10) and Kellies age (14). Take mikes age and add 4 to that on all of his ages. It equals to all of kellies ages. Therefore Kellies age is equal to mikes age plus 4. Did that help?

What is the solution of -4x = 100? O x=-2500 Ox=-50 Ox=-2.5 O no solution

In-s [12.5K]

Answer:

$x=-25$

(None of the answer choices you've provided match the correct answer.)

Step-by-step explanation:

Given:

$-4x=100$

To find the solution (what $x$ equals), we must divide both sides of the equation by the coefficient of

$x=25$

Therefore, the solution of $-4x=100$ is $x=-25$ .

We can check our work by substituting the solved value of $x$ into the given equation:

$-4x=100$

$-4(-25)=100$

$100=100$

Since both sides of the equation are equal to each other, our solution is correct!

7. Jack and Max share some counters. Jack has 3 times as many counters as Max.

FrozenT [24]

To answer this item, we let x be the number of counters that Max has. By the representation, the number of counters that Jack has is 3x.

a. Ratio of counters,
3x:x
which can be simplified by dividing by x both sides of the ratio giving us the answer of,
3:1

b. Fraction of counters Max have,
fraction = x / (x + 3x) = 1/4

A multiple-choice test in which each question has 4 choices only one of which is correct. Assume that 9 questions are answered b

yaroslaw [1]

Answer:

Therefore, the probability is P=0.0084.

Step-by-step explanation:

We know that a multiple-choice test in which each question has 4 choices only one of which is correct. Assume that 9 questions are answered by guessing randomly.

Because we have 4 choices only one of which is correct, we get that p=0.25 and q=0.75.

We calculate the probability of getting exactly 6 correct answers.

n=9 and k=6.

$P=C_k^n\cdot p^k\cdot q^{n-k}\\\\P=C_6^9\cdot 0.25^6\cdot 0.75^3\\\\P=84\cdot 0.0001\\\\P=0.0084$

Therefore, the probability is P=0.0084.
