Answer:
SSS
Step-by-step explanation:
The two triangles both share a side (the middle line), and it is shown that the other lines are congruent to each other. So all 3 sides are congruent, meaning SSS is the postulate that proves this.
I’m not sure if this is how you do it but:
2(8a - 12)
4(4a - 6)
8(2a - 3)
??
You can write an equivalent expression with this knowledge by taking a two numbers, and multiplying both of them by a number. You can extract the number by taking the gcf of both of them, and dividing them both by it and putting the numbers in a parenthesis and multiplying the numbers by the gcf.<span />
The exact answer is 1,166 (and two thirds, but surprise, you can't have two thirds of a person) which I got by dividing 7000 by 6. Simple stuff.
If you need an estimate though you could say something like 1,150, with the explanation that you knew 6 would go into 6000 one thousand times and then into the remaining 1000 about 150 times since a close benchmark, 5, would go in about 200 times, and then just added 1000 times to 150 times to get 1,150
3x + 8 = -48 |subtract 8 from both sides
3x = -56 |divide both sides by 3
x = -18 2/3
