Which equation is equivalent to 6 + 3(x + 4) = 13

Mathematics

Hello,

The correct answer is x = -5/3
Alternate forms: x = 1 2/3, x = 1.6

Step-by-step:

Remove parentheses

6 + 3x + 12 = 13

Add the numbers

18 + 3x = 13

Move constant to the right

3x = 13 - 18

Calculate the difference

3x = -5

Divide both sides

x= -5/3

Hope this helps!

Sliva [168]

Answer:

the answer is one over eight

the formula says required outcome divided by sample space

the sample space here is it because we have three coins and the Three coins have two faces each so it becomes 2 x 2 * 2 that is 8 and that is the total sample space we are supposed to get the probability of getting 3 tails and for each coin you have 1/2 x 1/2 x 1/2 and that is 1/8 as your final answer and do probability of getting three tails

Nelsons manufactures baseballs at a cost of $7.50 each with fixed costs of $10,000. If one baseball sells for $12, how many must
Allushta [10]
Profit = revenue - expenses
12000 = 12x - (7.50x + 10,000)
12,000 = 12x - 7.50x - 10,000
12,000 + 10,000 = 4.5x
22,000 = 4.5x
22,000 / 4.5 = x
4888.88 rounds to 4889 = x......4889 baseballs
