Answer:
To solve this equation we need to get x by itself.
4x-6=10x-3, (the first step would be adding 6 to both sides.)
4x=10x+3 (the next step is the subtract ten from both sides.)
-6x=3 (Last step is the divide both sides by -6.)
x=-1/2
Hope this helps ;)
X y
1 = 4
2 = 8
3 = 12
4 = 16
X = pounds
y = price
A weekly pay (five-day work week) is $100.
The average tip is $5.
The waiter wants to make at least $450 in a five-day work week.
So we have to find out how many times the waiter must serve.
So, first we do $450 - $100 since the waiter already makes $100.
$450 - $100 = $350
Then the waiter gets an average of $5 tips.
So, we do $350 / $5.
$350 / $5 = 70
Our answer is 70.
So, the waiter must serve 70 tables to make at least $450.
Hope this helps you! (:

Answer:
a. 97.72%
Step-by-step explanation:
The weights of boxes follows normal distribution with mean=28 ounce and standard deviation=0.9 ounces.
a. We have to calculated the percentage of the boxes that weighs more than 26.2 ounces.
Let X be the weight of boxes. We have to find P(X>26.2).
The given mean and Standard deviations are μ=28 and σ=0.9.
P(X>26.2)= P((X-μ/σ )> (26.2-28)/0.9)
P(X>26.2)= P(z> (-1.8/0.9))
P(X>26.2)= P(z>-2)
P(X>26.2)= P(0<z<∞)+P(-2<z<0)
P(-2<z<0) is computed by looking 2.00 in table of areas under the unit normal curve.
P(X>26.2)=0.5+0.4772
P(X>26.2)= 0.9772
Thus, the percent of the boxes weigh more than 26.2 ounces is 97.72%
Corresponding sides have the same ratio, so
x/15 = 12/(12+8) = 3/5
x = 15*3/5
x = 9
