Uhh.. so this is random like really random
Complete question:
Which equation accurately represents this statement? Check all that apply.
Negative 3 less than 4.9 times a number, x, is the same as 12.8
A: -3-4.9x=12.8
B: 4.9x-(-3)=12.8
C: 3+4.9x=12.8
D: (4.9-3)x=12.8
E: 12.8=4.9x+3
Answer:
B: 4.9x-(-3)=12.8
C: 3+4.9x=12.8
E: 12.8=4.9x+3
Step-by-step explanation:
The word equation can be expressed mathematically as follows
negative 3 → -3
less than 4.9 times a number , x → 4.9 x - (-3)
is same as 12.8 → 4.9 x - (-3) = 12.8
The equation can be expressed as
4.9 x - (-3) = 12.8
when you open the bracket, you multiply -3 time - 1 . MInus times minus is equals to plus. so you get
4.9 x + 3 = 12.8
12.8 = 4.9x+3
<em><u>The equivalent expressions are:</u></em>
<em><u>Solution:</u></em>
We have to find the equivalent expression for the given expression
Given expression is:
<h3><u>First equivalent expression:</u></h3>
Let us first use the algebraic identity
Therefore,
<h3><u>Second Equivalent expression:</u></h3>
From above we get,
2xy can be rewritten as xy + xy
Thus we get,
Group the terms we get,
Factor out "x" from first bracket and "y" from second bracket
Thus the equivalent expression is:
<h3><u>Third equivalent expression:</u></h3>
Therefore,
<h3><u>Fourth equivalent expression:</u></h3>
By commutative property we know that,
Therefore,
Thus the equivalent expressions are found
