M<A + m5x - 1 = 180
8x + 84 = 180
8x =96
x = 12

m<B = 3x + 5 = 3(12) + 5 = 41
m<C = 5x - 1 = 5(12) - 1 =59
and
m<A = 80

answer:

order from shortest to longest in ∆ABC
AC, AB, BC

P.S.
Smallest angle, shortest side.....
Largest angle, longer side....

Find the value of 5x-6 given that 2x-7=9

erik [133]

Answer:

Step-by-step explanation:

Given that

2x - 7 = 9 ← solve for x

Add 7 to both sides

2x = 16 ( divide both sides by 2 )

x = 8

Substitute x = 8 into 5x - 6

5x - 6 = (5 × 8) - 6 = 40 - 6 = 34

Why do some merchants, particularly smaller businesses, set a minimum purchase of $10 for any credit card transaction, or simply

amm1812

Because accepting credit cards cost the business small transaction fees. These businesses already have a paper thin profit margin, meaning if you buy less than $10 and use credit card, their profit is little to non-existent.
