2/5 plus 2/5 is five so we can assume if we multiply it by 4 it will be 10! 2/5 times 4 equals 10!!! Hope this helps! :D

-3/4x>12 solve for x

Ad libitum [116K]

Answer:

$\Huge\boxed{\mathsf{\rightarrow X$

Step-by-step explanation:

$\Large\boxed{\mathsf{SUBJECT: MATH}}$

Isolate x on one side of the equation.

Find the value of x.

First, multiply -1 from both sides.

(-3/4x)(-1)<12(-1)

Solve.

12(-1)=-12

3/4x<-12

Next, multiply 4 from both sides.

4*3/4x<4(-12)

Solve.

Multiply the numbers from left to right.

4(-12)=-48

3x<-48

Then, divide by 3 from both sides.

3x/3<-48/3

Solve.

Divide the numbers from left to right.

-48/3=-16

X<-16

$\Large\boxed{\Rightarrow \mathsf{X$

The correct answer is x<-16.

Answer:

hypotenuse = 10

Step-by-step explanation:

If you can tell at first glance it is a 3,4,5 triangle (6,8,10)/2=(3,4,5). Then you know that c has to equal 5.

If not,

a^2+b^2=c^2

6^2+8^2=c^2

36+64=c^2

100=c^2

10=c
