Answer:
The area is 2,600 cm^2
Step-by-step explanation:
The area of a rectangle is the product of its sides
And the difference between both areas is 1,400 cm^2 (P-Q)
Thus, we have it that;
40(3x-10) - (30(x + 15)) = 1,400
120x - 400 - 30x - 450 = 1400
120x -30x -400-450 = 1400
90x - 850 = 1400
90x = 1400 + 850
90x = 2,250
x = 2,250/90
x = 25
The area for painting P
is;
40 (3x - 10)
Substituting the value 25 for x
we have
40 ( 3(25) -10)
= 40(75-10)
40 * 65 = 2,600 cm^2

Answer:
$70 per tv
Step-by-step explanation:
if she gets $25 extra for each and her total made was $1,235 with 13 TV's you have to multiply 25 by 13 and get 325 then subtract that from 1,235 then get 910 which is what she made with just the fixing part so you divide that by 13 and get 70.
25x13=325
1,235-325=910
910/13=70 :)

Ken bought 2 video games and 1 DVD for a total of $105. Jerome bought 1 video game and 4 DVDs for a total of $80. Which system of equations can be
used to find the cost, in dollars, of each video game (v) and each DVD (d) at the store?
Answers
Answer:
I think that the Linear system of equations can be used to find the cost.
Step-by-step explanation:
Answer:
2v + 1d = 105
and
1v + 4d = 80
Step-by-step explanation:
ken : 2v + 1d = 105
Jerome : 1v + 4d = 80
1v + 4d = 80 Try to get a video games by its self
- 4d -4d
1v = 80 - 4d
Plug into kens equation..
2(80 -4d) + 1d = 105
160 - 8d + 1d = 105
-160 -160
-7d = -55
/-7 /-7
d = 7.86 (rounded)
Plug into Jeromes equation
1(7.86) + 4v = 80
- 7.86 - 7.86
4v = 72.14
/4 /4
v = 18.035 (round = 18)
What is the answer for m/1 =
Answers
=============================================================
Explanation:
The quickest way to get this answer is to add the angles given to get 87+46 = 133
This is through the use of the remote interior angle theorem.
Note how the angles 87 and 46 are interior, or inside the triangle. And also, they are not adjacent to the exterior angle we want to find. So that's where the "remote" portion comes in.
----------------
The slightly longer method involves letting x be the measure of the missing interior angle of the triangle.
The three interior angles add to 180
87+46+x = 180
133+x = 180
x = 180 - 133
x = 47
The missing interior angle of the triangle is 47 degrees.
Angle 1 is adjacent and supplementary to this 47 degree angle, so,
(angle1)+(47) = 180
angle1 = 180-47
angle1 = 133 degrees
This example helps confirm that the remote interior angle theorem is correct.

What is m∠A and what is m∠B?
Answers
Answer:
m∠A = 79°m∠B = 112°Step-by-step explanation:
We have cyclic quadrilateral as all vertexes are on the circle.
As per property of cyclic quadrilateral, each pair of opposite angles are supplementary.
As we know supplementary angles add up to 180°.
m∠A + m∠C = 180° ⇒ m∠A = 180° - 101° = 79°m∠B + m∠D = 180° ⇒m∠B = 180° - 68° = 112°A fair coin is tossed three times. What are all the possible outcomes? How many
