Answer:
Step-by-step explanation:
2y - x = - 7 ------------(I)
⇒ 2y = -7 + x ---------(II)
x + 2y = 3 ------------(III)
Substitute 2y = -7 + x in equation (III)
x + (-7 + x ) = 3
x - 7 +x = 3
2x - 7 = 3
2x = 3 + 7
2x = 10
Divide both sides by 2
x = 10/2
x = 5
Substitute x =5 in equation (I)
2y - 5 = -7
2y = -7 + 5
2y = -2
Divide both sides by 2
y = -2/2
y = -1
4y = 4*(-1) = -4
4y = -4

Like the given function is a linear equation with one variable (p). You can solve this equation replacing p for the informed value (-6).
Here it is important to remember the rules to addition of integers numbers:
+ + Add Final result (+)
- - Add Final result (-)
+ - Subtract Final result (the sign of the integer having greater value )
- + Subtract Final result (the sign of the integer having greater value )
If p=-6, then for p+4, you have:
-6+4=-2. The sign is negative because according to the rules to addition of integers numbers, you must use the sign from the larger number, in this case, -6.

i need help with an area math question
Answer:
Step-by-step explanation:
Area of outer triangle = [tex]\dfrac{4x*(4x+3)}{2}= 2x*(4x +3)[/tex]
= 2x*4x + 2x*3
= 8x² + 6x
Area of inner triangle= [tex]\dfrac{2x*(2x+5)}{2}=x*(2x+5)=x*2x+x*5=2x^{2} + 5x[/tex]
Area of aluminium = area of outer triangle - area of inner triangle
= 8x² + 6x + 2x² + 5x
= 10x² + 11x
Area of 20 aluminum borders = 20*(10x² + 11x) = 200x² + 220x
b) x = 25 cm
Area of 20 aluminum borders = 200*25² + 220*25
= 200 * 625 + 220*25
= 125000 + 5500
= 130500 cm²
c) Area of inner triangle (Glass) = 5500 cm²
Cost of aluminium = 130500 * 0.06 = $ 7830
Cost of glass = 5500 * 0.03 = $ 165
Cost of making 20 windows = 7830 + 165 = $ 7995
What is the measure of ∠C?
Answer: 38 degrees
Step-by-step explanation:
Because arc AB is equal to 76 degrees, angle ADB must also be 76 degrees.
Then simply take the supplement of the angle to get that < CDA is 104 degrees. Because it is part of an isosceles triangle, simply subtract 104 from 180 to get that <A + <C = 74 degrees. Because triangle ADC is isosceles (All radii of a circle are equal), simply divide 76 / 2 to get that <C = 38.

A box is 14 in. high, 18 in. Long, and 6 in. wide. What is the longest poster you could fit in the box? Use pencil and paper. Explain why you can only fit one maximum-length poster in the box but you can fit multiple 22-in. posters in the same box
Answer:22 Hope This Helps You :DD
Step-by-step explanation:
We will have the following:
First, we calculate the maximum length of a poster that can fit in:
l=[tex]\sqrt14^{2} +18^{2} =2\sqrt130 =22.8035[/tex]
So, the maximum length a poster can fit in is 22.80350885... inches.
Since the maximum ca only be fit once (Since it wil have the length of the diagonal of the box) and that in greater than 22 inches, we will have that multiple smaller 22 inch posters can be fit in.

Answer:
C then B
Step-by-step explanation:
If 2x > 50 , then x > 25. Draw a circle at x=25 and then extend a ray in the positive x direction away from x = 25.
If x + 6 < 32, subtract 6 from both sides, obtaining x < 26.
Draw a cirlce at x=26 and extend a ray from that x to the left.
Answer:
graph c is 2x> 50 and graph b is x+6<32
Step-by-step explanation:
For 2x>50 you first divide 50 by2 leaving you with x>25 therefore x is all numbers greater than 25.
For x+6<32 you first subtract 6 from 32 leaving you with x<26 therefore x is all numbers less than 26.

Find the missing character/number in the following figure?
Answer:
The correct answer is 5.
Step-by-step explanation:
For the first circle,
When we add 6,18,12,
we get 6+18+12 = 36
Now
when we divide 36 with 6 we get 6.
again,
for second circle,
When we add 10,53,18
we get 10 + 53 + 18 = 81
when we divide 81 with 9 we get 9.
Now
let the unknown number be x.
so,
Pattern : When we add all of the number in the circle excluding the smallest number and dividing it by the smallest number we get the same number.
following the pattern,
Here in the options x>=5 (smallest number in the circle 3)
so, we can take smallest number as 5.
As the pattern,
(x+10+10)/5 = x
or, (x+20)/5 = x
or, x+20 = 5x
or, 5x-x = 20
or, 4x = 20
so, x = 5
