ared with Tuesday. From Wednesday to Thursday, sales increased by an amount equal to 25% of Monday’s total sales.

Answer: 60 is the net change.

Step-by-step explanation:

(1) Monday's $2,000 with a 10% decrease in sales would be $200. 2,000 - 200 = $1,800

(2) If sales further decreased by 20% on Wednesday, then it would be $360. 1,800 - 360 = $1,440

(3) If sales increased by 25% from Monday's original total number of sales (2,000) that will be a $500 add-on to $1,440. 1,440 + 500 = $1,940

(4) So now you just subtract the final number of sales to the original number of sales. $2000 - $1,940 = 60

The area of a rectangle garden is 2g^2+34g+140. If the width is 2g+14 what is the length?
ASHA 777 [7]
We know  that
[area of rectangle]=length*width
area=2g²<span>+34g+140
</span><span>width =2g+14
</span>
step 1
find the roots of 2g²+34g+140

using  a graph tool-----> to resolve the second order equation
see the attached figure
the solution is 
g=-10
g=-7
so
2g²+34g+140=(2g+14)*(g+10)

therefore

the length is (g+10)

the answer is
the length is (g+10)

Find one positive angle and one negative angle that are coterminal with the given angle. Explain.
Setler [38]

Answer: 10) 615° & -105°

               12) -440° & 280°

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

Coterminal means it is in the exact same spot on the Unit Circle but one <em>or more </em>rotations clockwise <em>or counterclockwise.</em>

Since one rotation = 360°, add or subtract that from the given angle until you get a positive <em>or negative</em> number.

10) 255° + 360° = 615°     (this is a POSITIVE coterminal angle to 255°)

     255° - 360° = -105°     (this is a Negative coterminal angle to 255°)

12) -800° + 360° = -440°   (this is a Negative coterminal angle to -800°)

    -440° + 360° =  -80°      (this is a Negative coterminal angle to -800°)

      -80° + 360° = 280°     (this is a POSITIVE coterminal angle to -800°)

What is 2y+4x =10 in y=mx+b
Dimas [21]

Answer:

The answer should be y = -2x + 5

Step-by-step explanation:

Subtract 4x to move it to the other side.

(2y = -4x + 10)

Then you divide both sides by 2 to get y by itself.
