4x-5/7 - 2x+1/2 = 1/2 -x ans

Mathematics

serious [3.7K]3 years ago
8 0
First we simplify like terms:

4x-2x+1/2-5/7=1/2-x
2x-3/14=1/2-x

Then you add x to both sides to get everything with the variables together.

3x-3/14=1/2

Finally, you add 3/14 to both sides for the same reason.

3x=10/14 (simplifies to 5/7)

Then we divide by 3 to get x alone.

x=5/21

circumference= 2(pi)r OR (pi)d
d is diameter and r is radius

if the circumference is given, then you would have to work backwards.

in this case, Circumference = 78.5 ft

the equal you would use for the radius would be 78.5 = 2 x 3.14(pi) x r
- multiply 2 x 3.14 and get 6.28
- divide 6.28 on both sides to get ‘r’ by itself
- 12.5 = r

next, for the diameter you can use C= (pi) x d
- 78.5 = 3.14 x D
- divide 3.14 on both sides to get ‘d’ by itself
- 25 = d

hope this helps! make brainliest please

Without dividing,estimates the quotient for 3,328 divide by 6
Katarina [22]

Answer:

For this equation let's round the 3328 to a 3300.

Step-by-step explanation:

If we remove the 2 zeros, we remain with a 33. 33/6 is 5.5 Now if we add back 2 places we get 550. I know this is written badly, but I hope it helped.

So, we need to figure out how much times the body size of the flea it can jump. First, we need to figure out the size of the flea: <em>2^-4=0.0625</em>

Now that we have the size of the flea, we need to figure out how high it can jump: <em>2^3=8</em>

After we figure out the size of the flea, we need to divide 8 by .0625 because it is inverse operations to multiplication: <em>8/.0625=128</em>

Answer: The flea can jump 128 times higher than it's body size.
