(-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

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 consist of variables and coefficients, or constants. ] User: what is the algebraic expression for "the difference between seven times a number and three that number"? 7 -3x 7x- 3 7x- 3x Weegy: It is: 7x- 3x (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
