Answer:

j=-2

Step-by-step explanation:

42j+18-19j=-28

Combine like terms

23j +18=-28

Subtract 18 from each side

23j +18-18 = -28 -18

23j =-46

Divide each side by 23

23j/23 = -46/23

j = -2

Answer:

j = -2

Step-by-step explanation:

Simplify. First, combine like terms:

(42j - 19j) + 18 = -28

23j + 18 = -28

Isolate the variable, j. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and equals:

Parenthesis

Exponents (& roots)

Multiplication

Division

Addition

Subtraction.

~

First, subtract 18 from both sides:

23j + 18 (-18) = - 28 (-18)

23j = -28 - 18

23j = -46

Isolate the variable, j. Divide 23 from both sides:

(23j)/23 = (-46)/23

j = -46/23

j = -2

j = -2 is your answer.

Xander needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items.
Aleksandr [31]

Answer:

c ≥ 56   is the REQUIRED INEQUALITY.

Step-by-step explanation:

Here, the given  question is INCOMPLETE.

Xander needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items. Choose the inequality and solution to represent the number of cans, c, that Xander must still collect.

Now, here:

The number of cans Xander needed to collect = At least 120

The number of items already collected =  64

c: the number of cans, c, that Xander must still collect.

Now, the number of cans to be collected  - Cans already collected  

=  120 - 64  = 56

So, the number of can he must collect to make a TOTAL OF AT LEAST 120 cans  =  56 cans

⇒ The number of cans to be collected ≥ 56 cans

⇒c ≥ 56 cans

or, c ≥ 56   is the REQUIRED INEQUALITY.
