Answer:

2n+3

Step-by-step explanation:

Since the question is asking for "a number" times 2, the first thing that is necessary in any expression is 2n. Next, since there is "3 more", 3 must be added to the 2n. Combining this gives the translation 2n+3.

6x - 9 = a (3x + 2)<br> What value of a would result in an equation that has no solutions for x?

Umnica [9.8K]

Answer:

a = 2

Step-by-step explanation:

Given

6x - 9 = a(3x + 2)

If the coefficient of the x- term on the right side is 6 then the equation will have no solution, that is if a = 2, then

6x - 9 = 2(3x + 2) = 6x + 4 ( add 9 to both sides )

6x = 6x + 13 ( subtract 6x from both sides )

0 = 13 ← not possible

Thus equation has no solution when a = 2

How can you rewrite (z ≤ −1.75) in order to find the answer?

Dominik [7]

We can rewrite (z ≤ −1.75) in order to 4%.

We have given that (z ≤ −1.75).

We have to use the Normal Distribution is symmetrical

<h3>What is the Normal Distribution is symmetrical?</h3>

The normal distribution is symmetric and has a skewness of zero.

$P(z \leq -1.75)$

$P(z > > 1.75)$

$1 - P(z \leq 1.75)$

$1 - 0.9599$

$0.04001 \times 100=4.001 \%$

That is nothing but the 4%

A watermelon consists of 90% water and 10% pulp. After drying the weight is 20 kg

Anna [14]

Answer: 40kg

Explanation: If 40% water and 10% pulp (Total 50%) is 20kg
Then 90% water and 10% pulp (Total 100%) would be double, so therefore 40kg

To confirm: 10% = 4kg
40kg - 4kg = 36kg
to get from 90% to 40% just divide by 2.25
the answer is 16kg
add on the pulp weight of 4kg = 20kg
