How do u solve this equation 9*9-3*-25*+2*9*5

246

Step-by-step explanation:

You must use PEMDASMultiplication then division

 9 * 9  -  3 * -25 + 2 * 9 * 5

=   81   -    -75     +  10 * 90

=   81     +  75     +     90

=        156           +     90

=                  246

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
