Answer:
15/2 or 7.5
Step-by-step explanation:
-3÷ (-2/5)
The reciprocal of -2/5 is -5/2
So we multiply -3 into the reciprocal of the fraction and we can get the same answer
Therefore,
-3÷(-2/5)
= -3x -5/2
= (-5x-3)/2
(Two negatives become a positive)
= 15/2 in fraction form
And 7.5 in decimal form

Answer:
The meal was $20
Step-by-step explanation:
20%= 1/5
1/5=4/? ---> one converts to four by multiplying it by 4 so you should do the the same with the denominator which is five.
5×4= 20
Answer:
Side WZ=9
Step-by-step explanation:
Since he two are similar you need to make a ratio of the two parallelograms
The first tells you side FE is 2 and side EH is 3 so write it like this 2/3.
Next you need to do the same thing with the second parallelogram, so you know side XW is 6 but you don't know side WZ so you'd write this one 6/x.
You can do this since FE is similar to XW, because it is the same shape just bigger.
Next you take the two fractions adn set them equal to each other.
2 6
_ = _
3 x
Now cross multiply (2 timesx and 6 times 3)
It should look like this now
2x=18
Now all you have to do is divide by 2.
Answer:
okay so the first one ull need to kno pemdas so start with the perenthesis (5^2-10) and then the exponent 2^3 and multyply thats by 5 and what ever answer u got in the perenthisis u divide by what u got with the second side of the problem
