Twice the difference of x and 5 is -33

1 answer:

3 0

2*(x-5) = -33, so x-5 = -16.5, so x = -11.5

This is assuming that "the difference between a and b" is a-b, which seems to be the accepted interpretation.

Which is Bigger?

igomit [66]

A)
$43\%=\frac{43}{100} \\ \\
\frac{24}{60}=\frac{4}{10}=\frac{40}{100} \\ \\
43>40 \Rightarrow \frac{43}{100} > \frac{40}{100} \Rightarrow 43\% > \frac{24}{60}$

43% is bigger.

b)
$\frac{18}{30}=\frac{6}{10}=\frac{60}{100} \\ \\
0.51=\frac{51}{100} \\ \\
60>51 \Rightarrow \frac{60}{100} > \frac{51}{100} \Rightarrow \frac{18}{30} >0.51$

18/30 is bigger.

The perimeter of a triangle is 19z-7. One side is 5z-9 and one side is 8z+3. What is the remaining side ?

insens350 [35]

19z-7 - ( 5z-9 + <span>8z+3)
= 19z - 7 - (13z - 6)
= 19z - 7 - 13z + 6
= 6z - 1

answer
remaining side = </span> 6z - 1
