Stefan sells Jin a bicycle for ​$138 and a helmet for ​$16. The total cost for Jin is 40​% of what Stefan spent originally to bu
Brums [2.3K]
Stefan originally spent $61.60.

Explanation:
Equation: 40/100=x/154
100 is the whole because it is 40% out of a hundred. 154 is the sum of how much Jin bought the bike and helmet for. You would then be able to simplify 40/100 to 4/10. 154 divided by 10 would be 15.4. You would do the same to the numerator, so multiply 4x15.4. That would give you the 40% of what the bike and helmet were originally bought for.

In triangle NLM, point S is the centroid, QS = (3x – 5) cm, and NS = (4x) cm. What is NS? 5 cm 10 cm 20 cm 30 cm
son4ous [18]

Answer:

20 cm

Step-by-step explanation:

∵ S is the centroid of ΔNLM

∴ S divides NG at ratio 1 : 2 from the base

∴SQ = 1/2 NS

∴3x - 5 = 1/2 (4x)

∴3x - 5 = 2x

∴3x - 2x = 5

∴x = 5

∴ NS = 4 × 5 = 20 cm
