I'll mark the correct answer the Brainiest

Rufina [12.5K]

Answer:

Step-by-step explanation:

To find the sum, you most find the answers for both powers of tens. 10^2 is 100, so 4.9*100=490. 10^3 is 1000, so 6.8^1000= 6800. Add them together and you get 7290, which if divided by 1000, you get 7.29. Since 10^3 is 1000, the correct answer isE.

Is 2/15 and 3/30 proportional

lara [203]

Answer:

Step-by-step explanation:

To turn 15 into 30, you multiple 15*2=30.

If you do that to the bottom of the fraction, you should be able to do it to the top however, 2*2=4 not 3 so they are not proportional.

-11 + x =-7x -8(-x+1)

docker41 [41]

Step 1. Regroup terms

 $-11+x=-7x-8(1-x)$

Step 2. Regroup terms

 $x-11=-7x-8(1-x)$

Step 3. Expand

 $x-11=-7x-8+8x$

Step 4. Simplify $-7x-8+8x$ to $x-8$

$x-11=8-x$

Step 5. Cancel $x$ on both sides

$-11=-8$

Step 6. Since $-11=-8$ is false, there is no solution.

no solution

Done!
