Answer:
x = 6
y = -9
x = -25
Step-by-step explanation:
<u>1st Equation</u>
Step 1: Write out equation
3(4x - 3) - 19 = 8x - 4
Step 2: Solve
12x - 9 - 19 = 8x - 4
12x - 28 = 8x - 4
4x - 28 = -4
4x = 24
x = 6
<u>2nd Equation</u>
Step 1: Write out equation
-6y + 14 = 32 - 4y
Step 2: Solve
-2y + 14 = 32
-2y = 18
y = -9
<u>3rd Equation</u>
Step 1: Write out equation
-28 + 5 - 3x = 2 - 2x
Step 2: Solve
-23 - 3x = 2 - 2x
-23 = 2 + x
-25 = x
x = -25
Answer:
10% of 2,000 is 200. 2000 + 200 = 2200. 10% of 2200 is 220. 2200 + 220 = 2420. Answer is 2420.
Step-by-step explanation:
She starts off with 2000. She earns 10% of 2000 the first year. 10% of 2000 is 200. Then add to get the amount of money she has at the end of that year. 2000 + 200 = 2200. Then the next year she earns 10% of 2200. 10% of 2200 is 220. Add 2200 + 220. 2200 + 220 = 2420.
Answer:
I think 6
Step-by-step explanation:
They are all divisible by 6
We only have so many roses, so by finding out how many are used by these bouquets, we can deduce which one is possible.
1. 3 bouquets with 5 red roses and 10 white roses in each
Since there are 3 bouquets, and there are equal amounts of roses in each bouquet, multiply these values by 3 for the total number of roses used.
3*5 red roses=15 red roses
3*10 white roses=30 white roses
This is impossible, as we only have 20 white roses. This is incorrect.
2. 4 bouquets with 3 red roses and 7 white roses in each
Repeat the same process as used above.
4*3 red roses=12 red roses
4*7 white roses=28 white roses
Once again, this is impossible, as we only have 20 white roses. Still not right.
3. 5 bouquets with 3 red roses and 4 white roses in each
Repeat the same process
5*3 red roses=15 red roses
5*4 white roses=20 white roses
These are the exact limits we have, meaning this is possible to do. This is the correct answer.
4. 5 bouquets with 10 red roses and 15 white roses in each
Just to make sure we have the right answer, lets do the same process here.
5*10 red roses=50 red roses
5*15 white roses=75 white roses
This is way over the amount of roses permitted, so this is also incorrect.
Therefore, the correct answer is 5 bouquets with 3 red roses and 4 white roses in each. I hope this helps!
