Answer:
d <-15
In interval notation
(-∞,-15)
Step-by-step explanation:
-7d>105
Divide each side by -7. remembering to flip the inequality
-7d/-7 < 105/-7
d <-15
If George's bike weighs 15 pounds, then we can say that because Obed's bike is 3 pounds heavier than George's, Obed's bike weighs 18 pounds. If Obed's bike weighs 18 pounds, then we can say that because Elsa's bike is twice as heavy as Obed's, Elsa's bike weighs 9 pounds.
35x50=1,750-1,600=150. We need to find out what 150 is of 1,600.
150/1,600=?/100
1,600 divided by 100=16
do the same for 150
150 divided by 16=9.375
(you can make it whole if you want)
the answer is about 9%
For this case, what we must do is find the scale factor.
We have then that the scale factor is given by:
Where,
L1: side length of polygon ABCD
L2: side length of polygon PQRS
Note: both sides belong to the same side of each polygon
Substituting the values we have:
Rewriting we have:
Answer:
The scale factor of dilation is given by:
