Red = r
Blue = b
Green = g
Step 1: Write as algebraic equations.
r = b + 6
g = b - 4
Step 2: Merge the two equations together to form one, by adding them together.
r + g = b + b + 6 - 4
Step 3: Simplify.
r + g = 2b + 2
Step 4: Make b the subject.
2b + 2 = r + g
2b = r + g - 2
b = 0.5(r + g - 2)
ANSWER
b = 0.5(r + g - 2)

Answer:
a. <u>saletax</u><u> </u>= 98.75
100
<u>5</u><u> </u> = <u> </u><u>9</u><u>8</u><u>.</u><u>7</u><u>5</u>
100 1
we cross multiple
5(1) = 100(98.75)
5 = 100(98.75)
<u> </u><u> </u>divide both side by 5
<u>5</u><u> </u><u> </u>= <u> </u><u>1</u><u>0</u><u>0</u><u>(</u><u>9</u><u>8</u><u>.</u><u>7</u><u>5</u><u>)</u>
5 5
since 100 can divide 5 so we divide them
= 20(98.75)
amount sale tax = 1975
b. 98.75 × 5 =493.75$
Answer:
68%
Step-by-step explanation:
The mean is 32 minutes, and the standard deviation is 4 minutes.
28 is 1 standard deviation below the mean, and 36 is 1 standard deviation above the mean.
According to the empirical rule, 68% of a normal distribution is between -1 and 1 standard deviations. 95% is between -2 and 2 standard deviations. 99.5% is between -3 and 3 standard deviations.
So the answer is 68%.
Answer:
c. 42 miles per day
Step-by-step explanation:
From the information given, you can use a rule of three to calculate the constant rate that Kendra swims per day given that she swims 126 miles in 3 days:
3 days → 126 miles
1 day → x
x=(1*126)/3=42 miles
According to this, the answer is that Kendra swims 42 miles per day.
