Answer:

33 = - 20

Step-by-step explanation:

In this equation you have to use BEMA or PEMDAS (however you learned it) ot solve. (Brackets, Exponents, Multiplcation/Divison, Addition/Subtraction) or (Parentheses, Exponents, Multiplication, Division, Addition, SUbtraction)

5(3 +4) - 2 would be simplified down first to

5(7) -2 because parentheses are the first thing you do in any equation like this.

35 -2 because multiplication and divison are next due to the fact there are no exponents

33 because subtraction is last. You then do the same to the other side.

7 -3 (-2 +11)

7 + -3(9) (you can change the minus three to a plus negative three to make the next step more clear)

7 + -27

-20

33 = -20

slamgirl [31]

Answer:

6 dozens

Step-by-step explanation:

Vanilla, v = x

Chocolate, c = 3x

Strawberry, s = 3 dozens = 36

Total cupcakes = 132

Hence,

x + 3x + 36 = 132

4x = 96

x = 96 / 4

x = 24

Chocolate = 3 * 24 = 72

Dozens of chocolate = 72 /12 = 6 dozens

Suppose a 5x8 coefficient matrix for a system has pivot columns. Is the system consistent? Why and Why not?

Lyrx [107]

Step-by-step explanation:

All the 5 rows of the coefficient matrix (since it is of order 5×8) will have a pivot position. The augmented matrix obtained by adding a last column of constant terms to the 8 columns of the coefficient matrix will have nine columns and will not have a row of the form [0 0 0 0 0 0 0 0 1]. So the system is consistent.
