<h3>Answers:</h3><h3>First box = 57.14</h3><h3>Second box = 80</h3>
=============================================
Explanation:
If you save 65%, then you pay the remaining 35%
0.35x is the final price when x is the original price
0.35x = 20 solves to x = 57.14 approximately after dividing both sides by 0.35
57.14 goes in the first box
--------------
This must mean 80 goes in the other box.
Here's the steps on how to get 80
If you save 75% then you pay the remaining 25%
0.25x = 20
x = 20/0.25
x = 80
80 goes in the second box
<h3>Answer:</h3>
w+x+y+z = 12
<h3>Explanation:</h3>
When right angle ADC is divided into three equal parts (trisected), each of those parts is 90°/3 = 30°. Thus, ∠CDB = ∠PBD = ∠PDB = 30°.
The sides of a 30°-60°-90° triangle are in the proportion 1 : √3 : 2. Hence BD = 2, and PD = PB = 2/√3 = (2/3)√3.
Then the perimeter of ∆BDP is ...
... perimeter ∆BDP = BD + DP + PB
... = 2 + (2/3)√3 + (2/3)√3
... = 2 + (4√3)/3 . . . . . . . . w=2, x=4, y=3, z=3
w + x + y + z = 2+4+3+3 = 12
Answer:
14) 4x+10=8x-26 (corresponding angles are equal)
4x-8x=-26-10
-4x=-36
x= -36/-4= 9
x=9
15) perimeter of rectangle= 2(l+b)
2( l+
) = 40m
2l+
=40
Take LCM as 3
*
+
=40
= 40
= 40
10l=40*3
10l = 120
l= 120/10 =12 cm
l=12cm
b= 2/3 *12 = 8cm
16) 2:3:4
It can be written as 2x+3x+4x
sum of angles of a triangle =180 degree
so 2x+3x+4x=180
9x=180
x=180/9=20 degree
1st angle=2x=2*20= 40 degree
2nd angle= 3x=3*20 =60 degree
3rd angle= 4x=4*20= 80 degree
17) sum of interior angles of a pentagon is 540 degree
so, 125+88+128+60+x=540 degree
401 +x= 540 degree
x=540-401= 139 degree

The answer is C
The reason being these two sets of angles are opposite angles (also known as vertical angles) and opposite angles are always congruent.
