First add plus 5 to -5 and 22. Then -5 cancels outdo now u have 3b=27. Divide 3 to 3b and 27. Then you will have b=9
Answer:
y = 8/5x
Step-by-step explanation:
−3x + 7y = 5x +2y
+3x +3x
7y = 8x + 2y
-2y -2y
5y = 8x
/5 /5
y = 8/5x

For 25, I would begin with working out the difference in price.
$450 - $360 = $90
Then, $450 is 100% of the cost, therefore we want to know how much it has decreased.
I would work out 1% of $450. [$450 / 100 = $4.50]
Now if we divide $90 (the change in cost) by $4.50, we can tell what percent of a decrease we have.
90 / 4.5 = 20
Therefore we have a 20% decrease.

Answer:
True , because all properties preserved under dilation from triangle abc to a'b'c'.
Step-by-step explanation:
Given : A triangle abc is dilated by a factor of 2/3 , result triangle a'b'c'
To find :After dilation, properties of triangle abc and a'b'c' is true or false.
Solution:
Dilation of a triangle are result either decrease or increase the corresponding length of triangle , its depends on by which scale factor triangle is dilated ,and dilation does not affect the angle measures of triangle.here scale factor is 2/3 so corresponding sides of triangle a'b'c' decreases.
So, dilation of triangle are not congruent but similar to the original triangle abc
Therefore , basic properties of triangle preserved under dilation of triangle by a scale factor.
