You would use PEMDAS. So there are no P (parenthesis) so we move onto E (exponents). Since there are none of that we move onto M (multiplication) which is shown with (3 x 4). So that would be our first operation.

Following the order of operations, PEMDAS, multiplying 3 by 4 would be the first step, followed by dividing 9 by 9. Hope this helped, if not lmk.

The following numbers are given: 17, 25, 35, 43, 55, 119, 187. Choose four numbers from the given numbers and write them in the
9966 [12]

Answer:

Let's take two prime numbers and two composite numbers.

Prime numbers are 17 and 43

Composite numbers are 25 and 35 (119 and 187 are also composite but let's ignore them)

Now, while arranging it in the 2x2 grid so that the numbers in the neighbor boxes are not co-prime and the numbers in non-neighbor boxes are co-prime, the following arrangement will take place:

=> Number 17 in the upper left box

=> Number 25 in the upper right box

=> Number 35 in the bottom left box

=> Number 43 in the bottom right box.

PLEASE HELPPPXPDPD. If -5c+6=-69, what is the value of 6c-15?
crimeas [40]

Answer: 75

Step-by-step explanation:

To find the value of 6c-15, we first want to finc the value of c. Once we find c, we can plug it in and solve.

-5c+6=-69            [subtract both sides by 6]

-5c=-75                  [divide both sides by -5]

c=15

Now that we have the value of c, we can plug it in and solve.

6(15)-15                 [multiply]

90-15                     [subtract]

75

The value is 75.

Identify which lines are parallel.<br> y=2;y=x+2;y=2x-1;y=2x+1
Ne4ueva [31]

Answer:

y=2

Step-by-step explanation:

A parallel line are lines that never intersect.

-They are generally formed when a line when lines are perfectly horizontal to the x axis or the vertical to the y-axis.

=>y=2 is the only parallel line .

=>y=x+2 is not parallel as the (x+2) is not a constant

=>y=2x-1 is not parallel as the (2x-1) is not a constant

=>y=2x+1 is not parallel as the (2x+1) is not a constant
