Given : 7y=8x-14 and y =6
We plug in 6 for y in the given equation
Statement Reason
7y=8x-14, y=6 Given
7(6)= 8x-14 Substitution
56 = 8x Add 14 on both sides
7 = x divide by 8 on both sides
Hence proved x=7
Answer:x = 55
Explanation:In a parallelogram, the sum of each two consecutive angles is 180°.
In the given parallelogram ABCD, we can note that angles A and B are consecutive angles. This means that their summation is 180°
Therefore:
∠A + ∠B = 180
2x + 15 + x = 180
3x + 15 = 180
3x = 180 - 15
3x = 165
x = 165 / 3
x = 55
Now we can check:
angle A = 2(55) + 15 = 125°
angle B = 55°
angle A + angle B = 125 + 55 = 180°
Hope this helps :)
The number of masks that Mayerlin kept on her wall given the information in the question is 304.
<h3>What are percentages?</h3>
Percentage is the fraction of an amount that is usually expressed as a number out of hundred. Percentages are a measure of frequency.
<h3>How many masks are on the wall?</h3>
Percentage of the masks on the wall = 100 - 24 = 76%
Number of the masks on the wall = 76% x 400 = 304

Answer:
Therefore the results from adding the equation in this system is

Step-by-step explanation:
Given:
Equations as
.......................1
.......................2
To Find :
Result when adding equation 1 and 2 = ?
Solution
On adding equation 1 and 2 the "3y" term will get cancel and the like terms will combine that is add (11x and -4x ) and ( -17 and - 18) as shown below
11x - 3y = -17
-4x + 3y = - 18
-------------------------------------------
7x + 0 = - 35
---------------------------------------------
Therefore the results from adding the equation in this system is
