<span>To solve this problem you must apply the proccedure shown below:
1. You have the following expression given in the problem above: 7</span>√(3.2x)-3√(3.16x)-3√(3.8x)
2. To simplify it, you can factor √x, as following:
√x(7√(3.2)-3√(3.16)-3√(3.8))
3. When you solve the values inside the parenthesis, you obtain:
1.34√x
Therefore, the answer is: 1.34√x
Here you are Write<span> an absolute value equation </span>representing<span> the following; then ... both </span>x's<span> will be </span>7<span> units away from -3. if you do this correctly, you will find that </span>x<span> to the left is equal to -</span>10<span> and</span>x<span> to the right is equal to 4.</span>
x = the number of hot dogs
2.50x - 150 = 300
[You sell each hot dog for $2.50, you spent $150, you want to make $300]
2.50x - 150 = 300 Add 150 on both sides
2.50x = 450 Divide 2.50 on both sides
x = 180
You have to sell 180 hot dogs to make a profit of $300
[proof]
2.50x - 150 = 300
2.50(180) - 150 = 300
450 - 150 = 300
300 = 300
Answer:
z = 28
Step-by-step explanation:
Let's try this first:
6 = something - 1
Something = 7
Next:
We know that "something" is 1/4z
1/4z = 7
Divide both sides by 1/4 to isolate z
z = 28
Hope this helps :)
Have an awesome day!!
