1 Simplify \frac{4}{15}x
15
4
x to \frac{4x}{15}
15
4x \frac{4x}{15}=1.44
4x =1.44
2 Multiply both sides by 1515.
4x=1.44\times 15
4x=1.44×15
3 Simplify 1.44\times 151.44×15 to 21.621.6.
4x=21.6
4x=21.6
4 Divide both sides by 44.
x=\frac{21.6}{4}
x= 4
21.65 Simplify \frac{21.6}{4} 421.6 to 5.45.4.
x=5.4
x=5.4
3 ( x^8-4v) ........... .
7.8456 x 10^(-4)
this means you move the decimal place to the left 4 places to get the actual value
We can express it at 5 (a+6)
2a²b³ and -4a²b³ are like terms as they both have the same variables with the same degrees.
Your final answer is a. True.
