(-5.12) - (-4.7) (7.021)

=(0-5.12)-(0-4.7)×7.021

=-5.12-(0-4.7)×7.021

=-5.12- 4.7×7.021

=-5.12- 32.9987

=27.8787

=(0-5.12)-(0-4.7)×7.021

=-5.12-(0-4.7)×7.021

=-5.12- 4.7×7.021

=-5.12- 32.9987

=27.8787

the algebraic expression for "the difference between seven times a number and three that number"?

Weegy: An algebraic expression is one or more algebraic terms in a phrase. It can include variables, constants, and operating symbols, such as plus and minus signs. It's only a phrase, not the whole sentence, so it doesn't include an equal sign. [
Algebraic expression:
3x2 + 2y + 7xy + 5
In an algebraic expression, terms are the elements separated by the plus or minus signs. This example has four terms, 3x2, 2y, 7xy, and 5. Terms may ... (More)

Simplify. (-5.12) - (-4.7) (7.021)

Remember the order of operations PEMDA Parenthesis, Exponents, Multiply and divide, Add and subtract.

First multiple -4.7*7.021 to get a -32.9987

this leaves -5.12 - (-32.9987)

-5.12+32.9987

= 27.8787 rounded to two decimal places is 27.88

7 +8(x4 -8) =7

7 + 8(x^4) - 8(8) = 7

7 + 8x^4 -64 = 7

7 -64 + 8 x^4 = 7

-57 + 8x^4 = 7

-57 + 57 + 8x^4 = 7 + 57

8x^4 = 64

8x^4/8 = 64/8

x^4 = 8

sq rt of x^4 = sq rt of 8

x = 2.8284 or 2.83

7 + 8(x^4) - 8(8) = 7

7 + 8x^4 -64 = 7

7 -64 + 8 x^4 = 7

-57 + 8x^4 = 7

-57 + 57 + 8x^4 = 7 + 57

8x^4 = 64

8x^4/8 = 64/8

x^4 = 8

sq rt of x^4 = sq rt of 8

x = 2.8284 or 2.83
