I believe the answer is $10.70. First you divide $47.20 by 4. With the quotient, you subtract $1.10.

Solve for x 2x/3 +1 =3

Bess [88]

Answer:

x=3

Step-by-step explanation:

Hello,

The first thing you do is set up your equation, and we are solving for x so we are going to get x by itself on one side of the = sign.

2x/3+1=3 First thing: subtract 1 from BOTH sides.

-1 -1

----------------------

2x/3=2 Multipliy by 3 on both sides

*3 *3

-----------------------

2x=6 Divide by 2 on both sides

/2 /2

-----------------------

x=3

I hope this helped you!!!

The perimeter of a triangle is 56. The side lengths are x + 4, 3x + 7, and x + 9. What is the value of x?

Sidana [21]

<h3><u>Answer:</u></h3>

x = 7.2

<h3><u>Step-by-step explanation:</u></h3>

Perimeter: Side 1 + Side 2 + Side 3

=> x + 4 + 3x + 7 + x + 9 = 56

=> 5x + 20 = 56

=> 5x = 56 - 20

=> 5x = 36

=> x = 7.2

<h3><u>Conclusion:</u></h3>

Therefore, the value of x is 7.2.

Hoped this helped.

Need HELP PLS PIC ATTACHED

Answer:

$4x^{2}$ -13x+10

Step-by-step explanation:

(4x+5)(x-2)

Multiply each term in the first parenthesis by each term in the second (foil)

Step 1: Expand it by writing out each multiplication. I added a picture showing which order to do it. (go in order of green, red, blue, yellow.) (you can remember this as first, outside, inside, last.)

When you expand it'll look like: 4x⋅x+4x⋅-2-5x-5⋅-2

Step 2: Calculate product

4x⋅x+4x⋅-2-5x-5⋅-2 (for the 4x⋅x it would be written like $4x^{2}$ )

$4x^{2}$ +4x⋅-2-5x-5⋅-2

$4x^{2}$ +4x⋅-2-5x-5⋅-2 (4x⋅-2 becomes -8x) (multiply 4x times -2)

$4x^{2}$ -8x-5x-5⋅-2

$4x^{2}$ -8x-5x-5⋅-2 (-5⋅-2 becomes +10) (multiply -5 times -2)

$4x^{2}$ -8x-5x+10

Step 3: collect like terms

$4x^{2}$ -8x-5x+10 (-8x-5x becomes -13x) (-8x times -5x)

$4x^{2}$ -13x+10 is the most simplified so it should be your final answer
