x=4 because if you add 7 to 10 you get -2x-3=-14x then you add -2x to -14x and you get -3=-12 then you divide by -3 and -12 to get 4
Answer:
x = 12
Step-by-step explanation:
Solve for x:
(3 x)/4 = 9
Multiply both sides of (3 x)/4 = 9 by 4/3:
(4×3 x)/(3×4) = 4/3×9
4/3×3/4 = (4×3)/(3×4):
(4×3)/(3×4) x = 4/3×9
4/3×9 = (4×9)/3:
(4×3 x)/(3×4) = (4×9)/3
(4×3 x)/(3×4) = (3×4)/(3×4)×x = x:
x = (4×9)/3
9/3 = (3×3)/3 = 3:
x = 4×3
4×3 = 12:
Answer: x = 12
Answer:
43.1
Step-by-step explanation:
Look at the picture! Double check my work but I am pretty sure I did it correctly.
#4 = B
Explanation= Because C&A are the same angle measurement, and the 90 angle is along a straight line making the other angle 90, and the triangles share the same side the postulate you can use is AAS because you can prove that the triangles share 2 common angles and 1 common side
#5 = B
Explanation= Because the triangles already have 1 congruent angle, and 1 congruent side the only thing left we can prove is that because the triangles mirror each other, they have congruent opposite angles (may be called vertical angles) as well so they have 2 angles and 1 side in common which tells you to use AAS
Dealership A : 500 cash back , 5% tax
Becky : 15,000 + 0.05(15000) - 500 = 15,000 + 750 - 500 = 15,250
Michele : 20,000 + 0.05(20,000) - 500 = 20,000 + 1000 - 500 = 20500
dealership B : 1000 cash back, 8% tax
Becky : 15,000 + 0.08(15,000) - 1000 = 15000 + 1200 - 1000 = 15,200
Michele : 20,000 + 0.08(20,000) - 1000 = 20,000 + 1600 - 1000 = 20600
1. Becky will get the better deal at dealership B.....she saves 50 bucks
2. Michele will get the better deal at dealership A...she saves 100 bucks
3. ?....sorry
