Answer:
3x-2
Step-by-step explanation:
3 times a number is 3x, if we use x as the number
Two less than (3x) is 3x - 2
59.85 * .33= 19.7505
59.85 - 19.7505 = 40.0695
so rounded shoes would be $40.07
Answer:
John's determination incorrect because he didn't give a unit rate which is miles per hour (mph).
The actual unit rate for his trip is v;
v = 70 miles ÷ 2 hours
v = 35 miles per hour
v = 35mph
Step-by-step explanation:
Given;
John travels 70 miles in 2 hours
John's determination incorrect because he didn't give a unit rate which is miles per hour (mph).
The actual unit rate for his trip is;
v = 70 miles ÷ 2 hours
v = 35 miles per hour
v = 35mph

Step-by-step explanation:
A toolset sells for $150 at a local hardware store. The toolset is on sale for 20% off the retail price, p, given by f(p) = 0.80p. Devon is interested in buying the toolset and has a coupon for $30 off the price of the toolset, which can be represented by g(p) = p – 30.
Therefore, the cost of using the coupon followed by the discount,
f[g(p)] = 0.80(p - 30) = 0.80(150 - 30) = 96 dollars.
And the cost of using the discount followed by the application of the coupon,
g[f(p)] = 0.80p - 30 = 0.80 × 150 - 30 = 90 dollars.
Therefore, the difference between f[g(p)] and g[f(p)] is (96 - 90 ) = 6 dollars. (Answer)
