Answer:
x + 0.07x or 1.07x
Step-by-step explanation:
To find a percent of a number, multiply the decimal form of the percent by the other number.
7% = 7/100 = 0.07
This means 7% of x is 0.07x.
This would give us the amount of tax to be added; the total amount of the same, including tax, would be
x+0.07x
We can also consider this as adding an extra 7% of the cost. This means we would have 100% of the cost with another 7% of the cost; this is
100+7 = 107% of the cost. 107% = 107/100 = 1.07; this gives us 1.07x.
Answer:
Girl's basketball team has more seniors
Step-by-step explanation:
A varsity boy's basketball team has ratio of seniors to juniors that is 7:4.
Let there are 7x seniors and 4x juniors in boy's basketball team.
ATQ,
7x+4x = 12
11x = 12
x = 12/11
Seniors = 
The varsity girl's basketball team has a ratio of seniors to juniors that is 3 to 2.
Let there are 7x seniors and 4x juniors in girl's basketball team.
3x+2x = 12
5x = 12
x = 12/5
Seniors = 
As we can see that girl's basketball team has more seniors as compared to the boy's team.
Answer:
y = -3/2x - 3
Step-by-step explanation:

y = -3/2x + b
Step 2: Find y-intercept <em>b</em>
3 = -3/2(-4) + b
3 = 6 + b
b = -3
Step 3: Rewrite linear equation
y = -3/2x - 3
Answer:
