I found the value of x to be 6 by adding the two equations together and setting them equal to 180.

2x^2+3x-5+x^2+11x-7=180
When you solve for x you get x=6

Then you plug 6 in for x in each angle. The first angle is 85 and the second is 95.

13.Question- Write an expression using division and subtraction with a difference of 3.

answer-  (12 divide 3) -1

  Twelve divided by three is four. Four minus 1 is three.

12. Question- Write an expression using multiplication and addition with a sum of 16.

answer- There are many answers for this and this is one of them:

Y=4(3+1)

Y=16

or

Y=2(6+2)

Y=16

11.  Question- Sam bought two CDs for $13 each. Sales tax for both CDs was $3. Write an expression to show how much Sam paid in all.

answer- Expression- (13*2)(3*2)=$32

This is the answer because Sam bought two CD's for 13, 13*2, and the sales tax was $ 3, so 3*2=6

What algebraic expression represents GK?
dsp73

Answer:

Part a) GK=(7x+1)

Part b) GH=5 units and JK=8 units

Step-by-step explanation:

Part a) what algebraic expression represents GK?

we know that

GK=GH+HJ+JK

step 1

Find GH

we have

GH=GJ-HJ

substitute the given values

GH=(2x+3)-x=x+3

step 2

Find JK

JK=HK-HJ

substitute the given values

JK=(6x-2)-x=5x-2

step 3

Find GK

GK=GH+HJ+JK

we have

GH=x+3

HJ=x

JK=5x-2

substitute

GK=(x+3)+x+(5x-2)

GK=(7x+1)

Part b) If GK=15, what are GH and JK?

we know that

GK=(7x+1)

For GK=15

substitute the value of GK and solve for x

15=(7x+1)

7x=15-1

7x=14

x=2

<u><em>Find the value of GH</em></u>

GH=x+3

substitute the value of x

GH=2+3=5 units

<u><em>Find the value of JK</em></u>

JK=5x-2

substitute the value of x

JK=5(2)-2=8 units

elena-14-01-66 [18.8K]

Hello:<span>
the equation is : y = ax+b
the slope is a : a×(-3/4) = -1......( perpendicular to a line : </span>

3x+4y-22=0  : another equation is : y = (-3/4)x +22/4 with the slope : (-3/4))

<span>
a =4/3   </span>

 

<span>an equation  is : y - 4 = (4/3)(x-2)</span>
