Answer:

-4r - 11 = 4r + 21

-4r -4r = 21 + 11

The population of California is approximately 38,040,000. The population of Texas is approximately 26.06 x 10^6 . The population

Salsk061 [2.6K]

Answer:

this is it

Step-by-step explanation:

The population of California is approximately 38,040,000. The population of Texas is approximately 26.06 x 106 . The population of New York State is approximately 1.96 x 107

38,040,000 = 3.804 x 107

26.06 x 106 = 2.606 x 107

Which state has the highest approximate population? Show work and/or Explain.

NY: 1.96 x 107 = 19,600,000

TX: 2.606 x 107 = 26,060,000

CA: 3.804 x 107 = 38,040,000

California has the highest approximate population.

Find the sum of the approximate population of California and New York State.

(3.804 x 107) + (1.96 x 107) = (3.804 +1.96) x 107 = 5.764 x 107

Find the difference in the approximate population of Texas and New York State.

(2.606 x 107) - (1.96 x 107) = 0.646 x 107 = 6.46 x 106

Use the distributive property to remove the parentheses. Simplify your answer as much as possible.

goldenfox [79]

10x^3(8x^3+3x)

([10x^3 x 8x^3]+ [10x^3 x 3x])

80x^6+ 30x^4

•this is as simplified as it gets; it isn’t possible to add or subtract numbers with different exponents.

Which pair represents equivalent ratios?

TEA [102]

Answer:

Step-by-step explanation:

We can test each pair making each ratio into its simplest form.

For A 2/3 is already in its simplest form and 9/15=3/5. they are not equivalent.

For B, 5/8 is already in its simplest form and 15/21=5/7. they are not equivalent.

For C, 3/12=1/4, and 6/18=1/3. They are not equivalent.

For D, 4/10=2/5, and 12/30=2/5. They are equivalent.
