72-12k plz mark brainlest
Step-by-step explanation:
X+(x+1)=17
So 2x+1=17
Which means 2x=16
Which then means x=8
But you still need the second number, which is x+1, so 8+1=9.
This means that the consecutive numbers are 8 and 9.
Answer:
-3(4c-2) -2c = -14c+6
Step-by-step explanation:
We need to find the equivalent expression for -3(4c-2) -2c.
First we open the brackets as follows :
-3(4c-2) -2c
= -12c+6-2c
=-12c-2c+6
=-14c+6
So, the equivalent expression is -14c+6.
Answer:
<h2>

</h2>
Step-by-step explanation:
- 2(5y - 1) - y = - 4(y - 3)
Expand the terms in the bracket
That's
-10y + 2 - y = - 4y + 12
Group like terms
Send the constants to the right side of the equation and those with variables to the left side
That's
- 10y - y + 4y = 12 - 2
- 7y = 10
Divide both sides by - 7
We have the final answer as

Answer:
A. 3x + 12
B. US$ 34.50
Correct question and statement: Three friends went to lunch. They all ordered the same meal. At the end of lunch they gave the waiter a $12 tip.
A. Write a algebraic expression to represent the situation.
B. How much total money was spent if each meal cost $7.50?
Source: Previous question found at brainly
Step-by-step explanation:
A. If the three friends ordered the same meal, we have then:
x = Cost of the meal
Tip = US$ 12
<u>3x + 12 </u>
Total of the meal would be three times the cost of the individual meal, x, plus the tip.
B. Given that x = 7.50, how much was the total cost?
Let's use the equation we wrote in part A.
3x + 12
3 (7.50) + 12
<u>22.50 + 12 = 34.50</u>
