To round to a whole number look at the 1st digit after the decimal if it’s 4 or less you round down but if it’s 5 or more you round up a number. In this case u would round down and your answer would be 523

Whats an strategy you could use to compare 2 out of 6 and 5 out of 8

ElenaW [278]

You can use fractions to compare that. Make two shapes that are exactly the same, divide one of them into 6 equal pieces and divide the other one into 8 equal pieces. Shade in the 2 pieces in the first shape and then shade in 5 pieces out of the second shape.

2.3+0.02(x+20)-4.8=-9<br><br> Solve for x

Naya [18.7K]

Answer:

$x=-345$

Step-by-step explanation:

$2.3+0.02\left(x+20\right)-4.8=-9$

$\mathrm{Multiply\:both\:sides\:by\:}100$

$2.3\cdot \:100+0.02\left(x+20\right)\cdot \:100-4.8\cdot \:100=-9\cdot \:100$

$230+2\left(x+20\right)-480=-900$

$\mathrm{Subtract\:}230-480\mathrm{\:from\:both\:sides}$

$230+2\left(x+20\right)-480-\left(230-480\right)=-900-\left(230-480\right)$

$2\left(x+20\right)=-650$

$\mathrm{Divide\:both\:sides\:by\:}2$

$\frac{2\left(x+20\right)}{2}=\frac{-650}{2}$

$x+20=-325$

$\mathrm{Subtract\:}20\mathrm{\:from\:both\:sides}$

$x+20-20=-325-20$

$\bold{x=-345}$
