Answer:
5.3x - 4 .
Step-by-step explanation:
(6.7x -3) - (3.4x - 1) + (2x - 2)
1. using the commutative property:
= 6.7x - 3 + 2x - 2 - (3.4x - 1) (we can remove the parentheses around the first 2 groups because they are added).
2. Using the distributive property on the last group:
= 6.7x - 3 + 2x - 2 - 3.4x + 1 (distributing the negative over the parentheses).
3. Now adding like terms we get:
5.3x - 4 (answer).
Answer:
To prove triangles are similar, you need to prove two pairs of corresponding angles are congruent
Step-by-step explanation:
SSS similarity postulate
The SSS similarity postulate says that if the lengths of the corresponding sides of two triangles are proportional then the triangles must be similar.
In the given figure , we have two triangles ΔABC and ΔXYZ such that the corresponding sides of both the triangles are proportional.
i.e.
Then by SSS-similarity criteria , we have
ΔABC ≈ ΔXYZ

Jen is twelve years old and her mom is 38. 38 plus 12 is 50
Answer: 93 and 4/5
Step-by-step explanation:
6 7/10 divided by 1/14
= 67/10 divided by 1/14
= 67/10 x 14/1
= 67/5 x 7/1
= 469/5
Answer:
a-45
b-30
c-90
Step-by-step explanation:
blue shape-90 degree angle
pink is 45 since 2 make up a quadrant
aqua is 30 because half 2 quadrants equal 180.
180-(45x2)=90
90/3=30
hope this helps!
