-3x + 18 = 7x solve
Answers
Answer:
refer to the attachment
Step-by-step explanation:
hope that helps
-3x + 18 = 7x
First, isolate the variable. There’s a couple ways to do this. One is to subtract 7x from each side and subtract 18 from each side. The other is to add 3x to both sides. Either way, you end up with all the variables on one side and the rest on its own.
This would give us either…
-10x = -18
OR
18 = 10x
From there, divide by 10 to get a single x
-x = (-18/10)
-x = -1.8
Multiply each by -1 to find what positive x equals
x = 1.8
OR
(18/10) = x
1.8 = x

The probability that a red block is selected from a bucket is
3/8, and the probability that a blue block is selected is 2/8.
What is the probability that a red block or a blue block is
selected?
a) 1
b) 1/2
c) 5/8
d) 6/8
Answers
Answer:
5/8
Step-by-step explanation:
Since we don't know what the other color (s) are, all we need to do to determine the probability is add the two fractions, and that is your probability.
Answer:
5/8
Step-by-step explanation:
The probability of a red block shows 3/8. This means there are 8 blocks total and only 3 of them are red.
The probability of a blue block shows 2/8. Again there are 8 total blocks and only 2 are blue.
So the total number of blocks remains the same....8
The total of red and blue blocks is 3 + 2 = 5
So the probability would be 5/8

What value of x satisfies the equation 5(x – 3) – 2(x + 1) = 4?
Answers
Answer:
x = 7
Step-by-step explanation:
To solve:
Distribute 5 among everything inside the first parentheses. You'll get 5x - 15.
Next distribute -2 among everything in the second parentheses. You'll get
-2x - 2.
All together: 5x - 15 -2x - 2 = 4
Now combine like terms:
5x - 2x = 3x and -15 - 2 = - 17
All together: 3x - 17 = 4
Add 17 on both sides to get 21, and then divide both sides by 3. Answer is x = 7.
________________________________
Last, don't forget to check your work.
You can plug in 7 for x to get:
5(7 - 3) = 20
5 × 7 = 35
5 × -3 = -15
35 - 15 = 20
-2(7 + 1) = -16
-2 × 7 = -14
-2 × 1 = - 2
-14 -2 = -16
20 - 16 = 4
⬆⬆⬆Therefore this is correct.

in mixed number form: 5 7/12
Answer:
67/12 (just in case if they would ask you for the simplified form the answer in is 5 7/12)Step-by-step explanation:
convert both mixed fractions to improper fractions first
2 1/3 = 7/3 3 1/4 = 13/4
(cross multiplication method, to make both fractions have the same denominator)
7/3 + 13/4
7/3 × 4/4 = 28/12
13/4 × 3/3 = 39/12
28/12 + 39/12 = 67/12 (just add, denominator will remain the same)
67/12 (simplify)
67/12 = 5 7/12 (simplified)

A jewelry supply shop buys silver chains from a manufacturer for c dollars each, and then sells the chains at a 57-percent markup. Write the markup as a decimal, A expression for the retail price silver chain, a retail price of a silver chain purchased for 45 dollars, and how much was added to the original price of the chain
( if you answer all the questions i will mark you the Brainy-est. )
Answers
The amount added to the original price of the jewelery is the Markup price. Hence, the amount added is $16.34
Markup = 57% = 0.57Cost of jewellery = cRetail price = $45Retail price = cost of jewellery + Markup
$45 = c + 0.57c
45 = 1.57c
Divide both sides by 1.57
c = 45/1.57
c = $28.66
The Markup price = (Retail price - Original price)
Markup = $45 - $28.66 = $16.34Therefore, the amount added to the original price is $16.34
