Patrick purchased four new tires that were regularly priced at $95.99 each, but are on sale for $20 off per tire. If the sale ta
lbvjy [14]

$ 325.2372 will be charged on Patrick's Visa card.

<u><em>Explanation</em></u>

The regular price of each tire is $95.99 and the discount amount is $20 per tire.

So, the selling price of each tire will be: (95.99-20)dollar=75.99 dollar

and the total <u>selling price of 4 tires</u> = (75.99*4)dollar=303.96 dollar

The sale tax is 7%. So, the <u>amount of sale tax</u> = 7\% of 303.96 = (0.07*303.96)dollar = 21.2772 dollar

So, the total charge on Patrick's Visa card will be: (303.96+21.2772)dollar = 325.2372 dollar

Need help with this math problem
ladessa [460]

Answer:

m<1: 51

m<2: 61

m<3: 29

Step-by-step explanation:

m<1 = 51, because to find the 3rd angle, you need to add the other two angles and then subtract 180 from that answer.

61 + 68 = 129

180 - 129 = 51

m<2 = 61, because it's a vertical angle, meaning that the angle that's opposite to it exactly, is the same. So since the angle opposite to m<2 is 61, that's what the answer would be.

m<3 = 29, because all you need to do is add 90 and 61, and then subtract 180 by the answer. I got 90 as one of the angle measurements because there's a right triangle, meaning it's 90. Then since we already know what angle 2 is (61) then all you need to do is add:

90 + 61 = 151

Then subtract:

180 - 151 = 29

Rearrange the equation so b is the independent variable a-7=3(b+2)
ira [324]

Answer:

Step-by-step explanation:

a - 7 = 3(b + 2)

a - 7 = 3b + 6

a - 7 - 6 = 3b

a - 13 = 3b

(a - 13) / 3 = b <====
