X=3 because you subtract the three on both sides to get x alone. So you get: 7x=21 then you divide seven by 21 and get x=3
The length of the rectangle equals 80 cm, and the width equals 32 cm.
Divide the length to the width, we get the ratio between them :
80 : 32
Now, we simplify by dividing them both by the same number, in this case it's 16
=> 80 : 32 = (80 : 16) : (32 : 16) = 5:2
So, the ratio between the length and the width is 5:2
Percent means parts out of 100
36% =36/100=0.36
'of' means mulitply
27 is 36% of ? translates to
27=0.36 times ?
divide both sides by 0.36
75=?
the number is 75
Answer:
-2i+8
Step-by-step explanation:
(1+i)(3-5i)
3+3i-5i-5i^2
3-2i-5(-1), because i^2=-1,
3-2i+5
-2i+3+5
-2i+8
