Solve for x.

0.5x + 78.2 = 287

Answers

Answer 1
Answer: 0.5x + 78.2 = 287
          -78.2  -78.2

subtract 78.2 on both sides you will then get 0.5x = 208.8 you will then divide by 0.5 and the answer is x =  417.6
Answer 2
Answer:

Subtract 78.2 from both sides

0.5x+78.2-78.2= 287-78.2

0.5x = 208.8

Divide both sides by 0.5

0.5x/0.5= 208.8/0.5

x= 417.6


I hope that's help !

Will a 9/32 inch diameter pin fit into a reamed hole with a diameter of 0.278 inch? (Do not round off your answer and express it in fractionform)

Answers

Answer:

No, it won't

Step-by-step explanation:

Given

Pin\ diameter = (9)/(32)

Reamed\ hole\ diameter = 0.278

Required

Will the pin fit into the reamed hole?

For the pin to fit into the reamed hole, the diameter has to be smaller than that of the reamed hole.

In other words;

The pin will fit in if it satisfies the following condition

Reamed\ hole - Pin > 0

Reamed\ hole - Pin = 0.278 - (9)/(32)

Convert decimal to fraction

Reamed\ hole - Pin = (278)/(1000) - (9)/(32)

Simplify fraction to lowest term

Reamed\ hole - Pin = (139)/(500) - (9)/(32)

Take LCM

Reamed\ hole - Pin = (1112 - 1125)/(4000)

Reamed\ hole - Pin = (-3)/(4000)

This doesn't satisfy the condition Reamed\ hole - Pin > 0

Because (-3)/(4000) < 0

So, we can conclude that the Pin will not fit into the reamed hole

Bubba ordered pizza. So far he has eaten 3/8 of the large pizza. His uncle has eaten 1/8 of the pizza. How much of the pizza has been eaten so far

Answers


so: 3/8 + 1/8 = 4/8

and we know that 4/8 can be reduced to 1/2.

So, half of the pizza has been eaten so far.

To find out how much they both ate in all, you add the fractions of how much they ate. So that would be 3/8+1/8. And you add the numerators because the denominators are the same so that would be 4/8 or 1/2 of the pizza. Hope this helps.

Is - 3/5 greater, less than or equal to - 4/5

Answers

- 3/5 > - 4/5

They are both negative, so ignore the sign and compare the values. But we need to find which one is closer to the zero. 

4 is greater than 3, and we have a common denominator, so -3/5 is greater than -4/5, because -3/5 is closer to the zero.
it is greater than. Because as i learned it anything on the negative side that is farther away from zero is a smaller number and any thing near zero or after it is a big number. Hope this helped!
