Answer:

Step-by-step explanation:

5/8+ 3/8

Since the denominator is the same, we can add the numerators

(5+3) /8 = 8/8 = 1

5/8- 3/8

Since the denominator is the same, we can subtract the numerators

(5-3) /8 = 2/8 = 1/4

Answer:

$x=900$

Step-by-step explanation:

Read the problem carefully and figure out where it says plus and where it says per. Per implies multiplication. Plus is addition.

220+0.15x

To solve, plug in 355 for the answer and back solve for x.

$355=220+0.15x\\\mathrm{Switch\:sides}\\220+0.15x=355\\\mathrm{Multiply\:both\:sides\:by\:}100\\220\cdot \:100+0.15x\cdot \:100=355\cdot \:100\\22000+15x=35500\\\mathrm{Subtract\:}22000\mathrm{\:from\:both\:sides}\\22000+15x-22000=35500-22000\\15x=13500\\\mathrm{Divide\:both\:sides\:by\:}15\\\frac{15x}{15}=\frac{13500}{15}\\x=900\\$
