Answer:
34
Step-by-step explanation:
(10)(4)−(4)(3)−2x−6x+8+(−3)(4)+(6)(3)−(2)(2)+8x−4
= 40+−12+−2x+−6x+8+−12+18+−4+8x+−4
Combine like terms:
= 40+−12+−2x+−6x+8+−12+18+−4+8x+−4
= (−2x+−6x+8x)+(40+−12+8+−12+18+−4+−4)
= 34
The shapes are being used instead of variables.
For problem 4; start with clue 2, then clue 3, then clue 4, and lastly do clue 4.
<u>Clue 2</u>
3 · square - 8 = 19
3 · square = 27 <em>added 8 to both sides</em>
square = 9 <em>divided both sides by 3</em>
<u>Clue 3</u>
2 · triangle + 3 = -3
2 · triangle = -6 <em>subtracted 3 from both sides</em>
triangle = -3 <em>divided both sides by 2</em>
<u>Clue 4</u>
square + triangle = 6
(9) + (-3) = 6 <em>substituted solutions from Clue 2 and Clue 3</em>
6 = 6 <em>True statement confirms that Clues 2 & 3 are correct</em>
<u>Clue 1</u>
star + square = 12
star + (9) = 12 <em>substituted solution from Clue 2 </em>
star = 3 <em>subtracted 9 from both sides</em>
Answer: triangle = -3, star = 3, square = 9
For problem 5; do the same thing as problem 4 and start with Clue 2
Answers: triangle = -2, star = 10, square = 8
Answer:
-7 is bigger
-9 is bigger
-6 is bigger
7 is bigger
I think.....
-9,-8,-7,-6,-4
-9,-7,-6,4,7
-2-1,0,4,9
-8,-2,3,5,8 ?
I guess I didn't understand the question

Answer:
$60.79
Step-by-step explanation:
First take off the 30% from $78.95. That will leave you with $55.265.
Add 6% of $78.95 for sales tax (4.737) to the $55,265 = $60.002
Then add the 1% of $78.95 for local option tax (.7895) to the $60.002.
That gives you $60.7915 - round it to the nearest cent and it gives you
$60.79
