2 (k - 3) + 21 = -3 solve for K

Mathematics
1 answer:
Travka [436]3 years ago
8 0

Answer:  

2(k-3)+21=-3

We move all terms to the left:

2(k-3)+21-(-3)=0

We add all the numbers together, and all the variables

2(k-3)+24=0

We multiply parentheses

2k-6+24=0

We add all the numbers together, and all the variables

2k+18=0

We move all terms containing k to the left, all other terms to the right

2k=-18

k=-18/2

k=-9

Hope this helped :)

A pack of red pens can be divided into equal shares among 3, 5, 6 and 9 teachers with no pen left over?
Ugo [173]

Answer:

90 red pens

Step-by-step explanation:

we need to find the least common multiple of the numbers 3 , 5 , 6 , 9

6 = 2 × 3

9 = 3²

then

LCM(3,5,6,9) = 2×5×3² = 2×5×9 = 90

The number 90 can be divided into 3 ,5 ,6 ,9 with no remainder

Therefore the pack must have 90 pens or a multiple of 90

For example 180 , 270 ...

The question is missing the figure which is attached below.

Answer:

The last box that has dimensions 8 in × 8 in × 10 in

Step-by-step explanation:

Given:

Volume of the soil = 924 cubic inches.

There are four different types of boxes that need to be checked whether they can accommodate all of the soil or not.

The volume of the box must be at least 924 cubic inches to accommodate all of the soil.

Now, volume of the first box is given as:

V_1=l\times b\times h=20\times 5\times 10=1000\ in^3>924\ in^3

Volume of the second box is given as:

V_2=l\times b\times h=10\times 10\times 10=1000\ in^3>924\ in^3

Volume of the third box is given as:

V_3=l\times b\times h=10\times 20\times 6=1200\ in^3>924\ in^3

Volume of the fourth box is given as:

V_4=l\times b\times h=8\times 8\times 10=640\ in^3

Therefore, only the volume of the fourth box is less than the total volume of the soil. So, last box is the correct option.
