a. step 1: she distributed incorrectly
b. step 2: She subtracted 3x incorrectly
c. Step 3: she’s simplified incorrectly
d. step four: she subtracted 5 instead of adding 5

Answers

Answer 1

Answer:

Answer:

The mistake that Chelsea made was that she instead of adding 5 to both sides at step 4, she subtracted them. If she added the 5 instead of subtracting it, the answer she should've gotten was -2.

So, as you should know the volume of a cylinder is ( pi x r^2 x h ) and since it has a diameter and not the radius you would cut it in half therefore the radius is 4. 8/2=4 4*4= 16 16*14=224 224*3.14= 703.36 So, therefore your answer would be A. Hope this helps!

In the given figure , if AB l BD , then the value of x is

Answers

In the figure as we can see -

Angle 32 = Angle DAB (vertically opposite angles)

Angle ABD = 90 degrees

And we know that,

$Sum$ $of$ $all$ $angles$ $of$ $triangle$ $=180$ $degrees$

So,

$32+90+x+14=180$

$136+x=180$

$x=180-136$

$x=44$ $degrees$

$x+14+90+32=180\n x=44$

I need help with subtracting whole number fractions:'(

Answers

I think you mean mixed number fractions. So what you do is just subtract, both the fraction and also the number. So for example 1 2/3 - 1 1/3 is just 1/3 because you subtracted both of them
