Answer:

93 is also divisible by 3 (true).

Step-by-step explanation:

Given : 93 divisible by 3.

To find : Is 93 divisible by 3 . True or false.

Solution : We have given  93 divisible by 3.

By the divisibility rule:

If the sum of the digit of a given number is divisible by 3  then the given number must be divisible by 3 .

Example : 81

8+1 =9 that is divisibility by 3 so the 81 is also divisible by 3.

Now , 93 = 9+3 =12.

As we know 12 is divisible by 3.

So , 93 is also divisible by 3.

Therefore, 93 is also divisible by 3 (true).

Parallel to y = 2x – 5<br> going through (-6, 1)?
vovikov84 [41]

Answer:

y=2x+13

Step-by-step explanation:

Gradient of parallel lines are equal and in the equation,y=2x-5, 2 represents the gradient.

Therefore the gradient of the other line will also be 2.

Introduce another point (x,y) and then equate using the gradient as follows:

y-1/x--6=2

y-1/x+6=2

Cross multiplication;

(y-1)=2(x+6)

y-1=2x+12

y=2x+12+1

y=2x+13

Multiply: k+3 4k−2 ×(12 k 2 +2k − 4)
Dmitriy789 [7]
K+3 * 4k=12k
2(12k * 2 + 2k - 4) = 2(26k - 4)
= k + 12k - 2 (26k - 4)
- 2 (26k - 4) : -52k+8
=k + 12k - 52k = -39k
FINAL ANSWER = -39k + 8

Find x, if the perimeter is 106 <br> 3x+6<br> 2x-3
slega [8]
So we are given that the perimeter is 106 and two problems to solve
we will write this as an equation
106 = 3x + 6
we will subtract 6 from both sides
100 = 3x 
now divide by 3 to isolate the variable
we will get 33 1/3 as the x

for the second one
106 = 2x - 3
add three to both sides
109 = 2x 
divide by 2 to isolate the variable
we will get 54 1/2 as the x

Hope this helps :)

In a psychology class, 44 students have a mean score of 96.6 on a test. Then 13 more students take the test and their mean score
NikAS [45]

Answer: 89.7

Step-by-step explanation:

The mean of a data set is the average of all the information given. Therefore, the total combined score is the number of students multiplied by the mean

The total score of the first 44 students: 96.6*44 = <em>4250.4</em>

The total score of the later 13 students: 66.3*13 = <em>861.9</em>

(4250.4 + 861.9)/(44 + 13) = 89.7

Hope this helped
