Answer:

-20,2m-11,8

Step-by-step explanation:

rewrite it

2y+14,6m+3,8-(34,8m+15,6-2y)

remove the opposites

and then simplify

-20,2m-11,8

im not sure if this makes sense

What is the value of x? Please show step by step.

Start by using trig to find the length of the line LJ

The triangle KJL (big right angled triangle) has been given the following dimensions

Hypotenuse = 8 \sqrt{2}
The adjacent angle is 30 degrees

Since we have the hypotenuse and the  angle we must use the equation 
opposite = Sin(angle) x Hypotenuse

Opposite= sin30 x 8 \sqrt{2}

Opposite= 4 \sqrt{2}

Therefore line LJ is 4 \sqrt{2}


Now look at the smaller right angled triangle (LMJ) 

Hypotenuse is the line LJ which is 4 \sqrt{2}

The adjacent angle is 45

Since we have hypotenuse and angle we must use the equation opposite = sin(angle) * h

therefore 
x= 4 \sqrt{2} * sin45= 4

If T is the midpoint of SU find the values of x, ST and SU.
Nitella [24]

Answer:  The required values are

x = 12 units, ST = 60 units and SU = 120 units.

Step-by-step explanation:  Given that T is the midpoint of SU, where

ST = 5x  and  TU = 3x + 24.

We are to find the values of x, ST and SU.

Since T is the midpoint of SU, so we get

ST=TU\\\\\Rightarrow 5x=3x+24\\\\\Rightarrow 5x-3x=24\\\\\Rightarrow 2x=24\\\\\Rightarrow x=\dfrac{24}{2}\\\\\Rightarrow x=12.

So, the value of x is 12.

Therefore,

ST=5\times12=60

and

SU=5x+3x+24=8x+24=8\times12+24=96+24=120.

Thus, the required values are

x = 12 units, ST = 60 units and SU = 120 units.

You have 20 coins in your pocket that are either quarter or dimes. They total $3.95. How many quarters do you have? A.16 B.13 C.
bekas [8.4K]

Answer:

B. 13

Step-by-step explanation:

Solve this by setting up system of equations:

0.25x + 0.10y = 3.95

x + y = 20

x equals the number of quarters and y equals the number of dimes. 0.25 is the value of a quarter and 0.10 is the value of a dime.

1. Multiply one equation to have the same coefficient as the other

0.10 · (x + y = 20) = 0.10x + 0.10y = 2

2. Subtract to find the value of one variable

 0.25x + 0.10y = 3.95

<u>- 0.10x + 0.10y = 2</u>

0.15x = 1.95

3. Solve for x by dividing both sides by 0.15

x = 13
