Answer:

-90 < j OR

j > -90

Step-by-step explanation:

Given that:

3 >j/-2 - 7

By simplifying

Add 7 on both sides we get

3 + 7 >j/-2 - 7 + 7

10 > j/-9

Multiplying both sides by -9 (inequality will be inverted)

10* -9 < j/-9*-9

-90 < j

i hope it will help you!

What is the first step needed to solve 2 over 5 multiplied by x minus 6 equals negative 16 ? (1 point) Subtract 16 from both sid

AfilCa [17]

Answer:

The first step is Add 6 to both sides

Step-by-step explanation:

we have

$\frac{2}{5}x-6=-16$

Solve for x

That means ----> isolate the variable x

step 1

Adds 6 both sides

$\frac{2}{5}x-6+6=-16+6$

$\frac{2}{5}x=-10$

step 2

Multiply by 5/2 both sides

$\frac{2}{5}x(\frac{5}{2})=-10(\frac{5}{2})$

$x=-25$

therefore

The first step is Add 6 to both sides

4.7- 7.25x + 8.623x -3.8 you have to simplify it

baherus [9]

4.7 -7.25x+ 8.623x -3.8
= (4.7 -3.8)+ (8.623x -7.25x) (combine like terms)
= 0.9+ 1.373x

The final answer is 1.373x+ 0.9~

Answer:

2% (rounded to nearest percent)

Step-by-step explanation:

The formula is already given.

From the problem, we can say that:

Actual Value = 13.6

Experimental Value = 13.3

To find percentage error, we use the formula [remember, the numerator of the formula has absolute value, so if we find any negative answer, that would becomes positive value]. lets do this:

Percent Error = $\frac{|13.3-13.6|}{13.6}*100\\=\frac{|-0.3|}{13.6}*100\\=\frac{0.3}{13.6}*100\\=0.0221*100\\=2.21$

So, 2.21%

Rounded to nearest percent, that would be 2%
