Write the number 258 in expanded form

200 + 50 + 8

Step-by-step explanation:

Just Put some zeros in

200 + 50 + 8

Step-by-step explanation:

Step 1:  Find how many hundreds

2 hundreds

200 ones

Step 2:  Find how many tens

5 tens

50 ones

Step 3:  Make expanded form

200 + 50 + 8

 200 + 50 + 8

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
