I assume you meant to type the following:
3/(5k-5) = 7/100
When we multiply both sides by (100)(5k - 5), we get this:
300 = 7(5k - 5)
300 = 35k - 35
300 - 35 = 35k
265 = 35k
265/35 = k
This would be 32 Dime totaling $3.20 an 34 nickles for 1.70
34*5+170 aka 1.70
32*=320 aka 3.20
3.20+1.70+4.90
Answer:
5. 540°
Step-by-step explanation:
m<a + m<c = 180°
m<h + m<f = 180°
m<k + m<m = 180°
Then m<a + m<c + m<h + m<f + m<k + m<m = 180° x 3 = 540°
Answer: A
Step-by-step explanation:
a • (b•c) = (a•b) • c
