Points A B C D and E are collinear and in that order. Find AC if AE=x+50 and CE=x+32

Lana71 [14]

Answer:

Step-by-step explanation:

Points A B C D and E are collinear.

$\therefore AE = AC + CE\\\therefore AC = AE - CE\\\therefore AC = x + 50 - (x + 32) \\\therefore AC = x + 50 - x - 32 \\\therefore AC = 50 - 32 \\ \huge \red{ \boxed{\therefore AC = 18}}$

A man earns 12,000 per year, 10% of it was spent on transport while 5% of the salary went as tax. He spent 80% of the remainder

weqwewe [10]

Answer:

Amount left = 2040

Step-by-step explanation:

Given that:

Per year salary = 12,000

Amount spent on transport = 10%

Transport = $\frac{10}{100}*12000$ = 0.1 * 12000

Transport = 1200

Tax = 5%

Tax = 0.05 * 12000

Tax = 600

Total = 1200 + 600 = 1800

Amount left = 12000 - 1800 = 10200

Food = 80% of remainder

Food = 0.8 * 10200

Food = 8160

Amount left after food = 10200 - 8160 = 2040

Hence,

Amount left = 2040
