Answer:
x = 7 and y = -2
Given:
x = 5y + 17 _____first equation
2x + 3y = 8 ____second equation
Steps:
2x + 3y = 8
<em>plug in x = 5y + 17 into second equation</em>
<em></em>
2(5y + 17)+3y = 8 [ open the brackets ]
10y + 34 + 3y = 8
10y + 3y = 8 - 34 [ collect and group terms ]
13y = -26 [ divide both sides by 13 ]
y = -2 [ final answer ]
solve for x:
x = 5y + 17
x = 5(-2) + 17
x = 7
Answer: Choice B)
(y+5)+y = 6
----------------------------------------------------------------
So what we do is start with x+y = 6. We can replace the 'x' with (y+5). This replacement is possible because x = y+6; ie x and y+6 are the same. Another term for "replace" is "substitute"
This is how we're able to go from x+y = 6 to (y+5)+y = 6
Answer:
w=32
Step-by-step explanation:
w/4 = 8
4/1 * w/4 = 8*4
w=32
With questions like these, I like to use a system of operations my teacher told me.
First, we have to identify what the question is asking us to find. The question is asking us to find how many bouquets a florist makes per day (which is in one day).
Then, we have to find information that will help us answer the question. She makes 215 bouquets is 5 days.
Now, you put it together!
If she makes 215 bouquets in 5 days, and we need to find out how many she makes in 1 day, we need to divide 215 by 5!
215 / 5 = 43.
The florist makes 43 bouquets per day!
<span>In the Franco-Dahomean War in the 1800s, many French soldiers hesitated before attacking the Dahomey Amazons, which led to the death of a large number of French troops. This hesitation may have been due to cultural beliefs about men fighting women. What is your belief about this? How does it apply to current political debates about women serving in the front of ongoing wars?</span>
