Step-by-step explanation: idid the test and i got it right
For this case, we have that by definition, the proportions can be expressed in different ways. Example, if we have a dog and three cats:
75%: It's percentage
0.75: In decimal (75% are cats)
: In fraction. (There are
of cats)
: Using ":" to separate sample values. (For every three cats there is a dog)
Care should be taken with the proportions, always multiplying the numbers in the proportion by the same value.
Example:
Answer:
Care should be taken with the proportions, always multiplying the numbers in the proportion by the same value.
A=b+1
a=2b+9
b+1=2b+9
-b from both sides
1=b+9
-9 from both sides
-8=b
b+1
-8+1
-7
You can check your answer...
2b+9
2(-8)+9
-16+9
-7
The smaller is -8 and the larger is -7
Answer:
Gather your like terms together
Step-by-step explanation:
(x+4x+x) = 6x
(-10-10+2) = -18
6x -18 = 180 (the sum of triangle angles)
Add 18 to both sides
6x = 198
divide 198 by 6
x = 33
