1. Which of the following equations have the correct solution Select all that apply. 3x + 7 = 10; x = -1
5(x + 4) - x = 40; x = 5
**3 = 3; x = 12
0 9 = 7x -9; x = 0
0 7 = 5x +5; x = 6
taments hy determining what value(s) for the variable

Do it yourself

Step-by-step explanation:

this is ur homework not mine

0ption b and e is correct.

hope it helps u

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
