Percent error=(experimentally determined boiling point-actual boiling point)

                   =(124.1 - 125.7) = 1.6 °C

Percentage error is \frac{1.6\times 100}{125.7} = 1.27%

 (5.3 x 10⁴) + (1.3 x 10⁴) =6.6 x 10⁴

(7.2 x 10⁻⁴) ÷ (1.8 x 10³)=4 x 10⁻⁷

10⁴ x 10⁻³ x 10⁶=10⁷

(9.12 x 10⁻¹) - (4.7 x 10⁻²)=(9.12 x 10⁻²) - (4.7 x 10⁻²)

Step-by-step explanation:

hope this helps

C

Step-by-step explanation:

17 +9

26

you have to get x on its own; plus nine on both sides.

C.

Step-by-step explanation:

x-9 = 17

Adding 9 to both sides,we'll get

x = 17+9

x = 26

\frac{x}{10} = -7   Multiply both sides by 10
x = -70

C. x = -70

1) the solution to the inequality

10x + 18 < −2 is A. x<−2
proof:  10x + 18 < −2  and 10x < −2 -18=-20 so  10x<-20 implies x< -20/10=-2
2)  the solution to the inequality

−6x + 5 > −1 is B. ​ x<1 ​
proof: −6x + 5 > −1  -6x>-1-5= -6, - 6x> -6 implies x< -6/-6=1  

3) let's solve −4.2y + 2.1 > −2.52

if −4.2y + 2.1 > −2.52 so  −4.2y  > −2.52 -  2.1=  - 4.62
−4.2y  > - 4.62 implies   y< - 4.62  /  - 4.2=1.1
so y<1.1

4) let's solve −4/3x + 1/6 < 7/9

if −4/3x + 1/6 < 7/9  then  −4/3x < 7/9 -1/6=7/9 -1/6 (multiplied by 3 for each member) we have   −4x < 7/3 -1/2=(2x7-1x3)/2x3=11/6, it means  −4x < 11/6
and then x>11/-24, x> -11/24

the solution set of 

−9.5x−1.5>−30 can be found by solving this inequation, 

−9.5x>−30 +1.5  −9.5x> -28.5  so it means    x< 28.5/9.5=3
x<3, the solution set is   S=  ] -infinity,  3[
10-54-24x=10x-120+8. -34x=-68. 34x=68. x=2. B.x=2.
