Find the value of x in the
following parallelogram:
2x - 1
11
7
x = [?]
Answer:
[tex]x = 4[/tex]
Step-by-step explanation:
See attachment for complete question
From the attachment, the parallelogram has two diagonals. And the diagonals of a parallelogram bisect one another.
Because 2x - 1 and 7 are opposite sides of a diagonal; We can say that:
[tex]2x - 1= 7[/tex]
Add 1 to both sides
[tex]2x - 1 + 1 = 7 + 1[/tex]
[tex]2x = 8[/tex]
Divide through by 2
[tex]x = 4[/tex]

Sumalee and Scott each improved their yards by planting daylilies and ivy. They bought their
supplies from the same store. Sumalee spent $93 on 6 daylilies and 3 pots of ivy. Scott spent
$196 on 13 daylilies and 6 pots of ivy. Find the cost of one daylily and the cost of one pot of ivy.
Answer:
The cost of one daylily is $10 and the cost of one pot of ivy is $11
Step-by-step explanation:
To solve the question we will form a system of equations
Assume that the cost of 1 daylily is x and the cost of 1 pot of ivy is y
∵ Sumalee spent $93 on 6 daylilies and 3 pots of ivy
→ Multiply x by 6, y by 3, then add the products and equate the sum by 93
∴ 6x + 3y = 93 ⇒ (1)
∵ Scott spent $196 on 13 daylilies and 6 pots of ivy
→ Multiply x by 13, y by 6, then add the products and equate the sum by 196
∴ 13x + 6y = 196 ⇒ (2)
Now we have a system of equations to solve it
→ Multiply equation (1) by -2
∵ -2(6x) + -2(3y) = -2(93)
∴ -12x - 6y = -186 ⇒ (3)
→ Add equations (2) and (3)
∵ (13x + -12x) + (6y + -6y) = (196 + - 186)
∴ x + 0 = 10
∴ x = 10
→ Substitute the value of x in equation (1) to find the value of y
∵ 6(10) + 3y = 93
∴ 60 + 3y = 93
→ Subtract 60 from both sides
∵ 60 - 60 + 3y = 93 - 60
∴ 3y = 33
→ Divide both sides by 3
∴ y = 11
∴ The cost of one daylily is $10 and the cost of one pot of ivy is $11
What is a 217 for the sequence -10,-7, -4,-1, ...
Answer:
a(217)=638
Step-by-step explanation:
a(n) = a +(n-1)d
a=-1
d=-7+10=-4+7=3
a(n) = -10 +(n-1)3
a(217) = -10 +(217-1)3
= -10+648
=638

The regular price of a coat is $35.25. During a sale, the coat rang up for $19.99. What was the percent off of the coat during the sale? (5 points)
a
The sale was for a 43% decrease.
b
The sale was for a 76% increase.
c
The sale was for a 76% decrease.
d
The sale was for a 43% increase.
Answer:
a
The sale was for a 43% decrease.
Step-by-step explanation:
The computation of the percent off of the coat during the sale is shown below:
Regular price is $35.25
And, in the sale the price is $19.99
So, the percent off would be
= ($35.25 - $19.99) ÷ ($19.99)
= 43% decrease
hence, the percent off of the coat during the sale is 43% decrease
Therefore the correct option is a.
And, all the other options are incorrect

(y2 + 6)(-2y + 7) =
Answer:
See attached image
Step-by-step explanation:
Use the FOIL method
First - multiply the first numbers inside the parentheses (y^2 and -2y)
Outer- multiply the first and last numbers inside the parentheses (y^2 and 7)
Inner - multiply the two numbers next to the closing and opening parentheses (6 and -2y)
Last- multiply the last two numbers in the parentheses. (6 and 7)
Then simplify to put it in standard form.
Point Q was rotated about the origin (0,0) by -45 degrees
Answer:
0,0
Step-by-step explanation:
The point Q was rotated about the origin (0,0) by -45 degrees, so the new coordinate point is (√2, 4√2).
From the given graph, the coordinates of point Q are (-3, 5).
Rotating the co-ordinate axes through an angle of 45° in anti-clockwise direction is equivalent to rotating the point through an angle of -45° about origin.We will use rotation from complex numbers to solve this.
Let x + iy the new complex number
(-3+5i)[tex]e^{\frac{-\pi i}{4} }[/tex]
= (-3+5i)((1-i)/√2)
= (-3+5i)(1-i) ×1/√2
= (-3+5i+3i-5i²) ×1/√2
= (-3+8i+5) ×1/√2
= (2+8i) ×1/√2
= (2/√2 + 8i/√2)
= (√2 + 4√2i)
So, the coordinates are (√2, 4√2)
Therefore, the point Q was rotated about the origin (0,0) by -45 degrees, so the new coordinate point is (√2, 4√2).

One cellphone provider DU charges AED10 per month plus an activation fee of AED20. A second cellphone provider ETISALAT charges AED11 per month plus an activation fee of AED15. For what number of months is the cost of either cellphone provider the same?
Answer:
5 months
Step-by-step explanation:
One cellphone provider charges AED10 per month plus an activation fee of AED20.
If I used the services of this cellphone provider for x months, total charges for the services,
y = 10x + 20 --------(1)
Similarly, charges for the second cellphone provider for x months of uses will be,
y = 11x + 15 -------(2)
Input-output table for equation (1)
x 1 2 3 4 5
y 30 40 50 60 70
Input output table for equation (2)
x 1 2 3 4 5
y 26 37 48 59 70
From these tables, we find (5, 70) is a common point for both.
It reveals that after the uses of 5 months charges for both the cellphone providers will be same (y = $70)

All of the following are equivalent, except _____.
(8 + 3)x
11x²
11x
8x + 3x
hellllllllllllppppppppppp
Explanation:
Choice A combines to 11x since the 8+3 simplifies to 11.
Choice D is a very similar story. Think of having 8 boxes, which we denote in shorthand as 8x. Then adding on 3 more boxes leads to adding on 3x. Having 8 boxes plus another 3 boxes gives 8+3 = 11 boxes total. So that's why 8x+3x = 11x. Alternatively, we can factor out the x to say 8x+3x = (8+3)x.
This shows choices A,C, and D are equivalent expressions. Choice B is the odd one out.
Which is the solution to the equation 8.25 + one-fourth w = 10.75? Round to the nearest hundredth if necessary.
Answer:
w=10

2(6-x)=3 please help
Answer:
x = 4.5
Step-by-step explanation:
Let's solve this together!
First you would want to multiply 6 and x:
6×2 = 12
x×2 = 2x
Then you would want to subtract 12 from 3:
3+12 = 9
Then divide 9 by 2:
9÷2 = 4.5
x=4.5
That's it!

Andy, Fergus, Evelyn, and Margaret are collecting cans for recycling. Before lunch they have collected a total of 173 cans. At the end of the day, the total number of cans collected can be represented by the expression 173 + n . What does the variable n in the expression represent?
Answer:
n = The number of can collected after lunch
Step-by-step explanation:
Andy, Fergus, Evelyn, and Margaret are collecting cans for recycling.
From the question, the told number rod cans collected before lunch = n
We are told that :
At the end of the day, the total number of cans collected can be represented by the expression 173 + n .
The total number of cans = Number of cans collected before lunch + Number of cans collected after Lunch
Hence:
173 + n = 173 + Number of cans collected after Lunch
Therefore, the variable n = Number of cans collected after Lunch

Muriel says she has written a system of two linear equations that has an infinite number of solutions. One of the equations of the system is 3y = 2x – 9. Which could be the other equation? 2y = x – 4.5 y = y equals StartFraction 2 over 3 EndFraction x minus 3.x – 3 6y = 6x – 27 y = y equals StartFraction 3 over 2 EndFraction x minus 4.5.x – 4.5
Answer:
B is correct
Step-by-step explanation: an infinite number of solutions means a coincident line...it is the same line
3y = 2x - 9...divide by 3
y = 2/3x - 3...hmm...same line as answer choice b....they are coincident lines and have infinite solutions

Answer:
Step-by-step explanation:
2) ∠A + ∠B = 146 {Exterior angle theorem}
5y + 3 + 4y + 8 = 146
5y + 4y + 3 + 8 = 146 {combine like terms}
9y + 11 = 146
9y = 146 -11
9y = 135
y = 135/9
y = 15
3) m∠A = 5y + 3
= 5*15 + 3
= 75 + 3
∠A = 78
4) m∠B = 4y + 8
= 4*15 + 8
= 60 + 8
m∠B = 68
5) m∠ACB + m∠A + m∠B = 180 {Angle sum property of triangle}
m∠ACB + 78 + 68 = 180
m∠ACB + 146 = 180
m∠ACB = 180 - 146
m∠ACB = 34

Write ✓-49 as an imaginary number using i.
please help me for 50 point
Answer:
54
Step-by-step explanation:
So If this tells you what 'm' and 'n' are, you just put them inside.
First do the M so then it will be 5 * 10 which is 50 then we just first leave it there. Then we start putting in that N. We know that N is 4. Then it's N to the power of 2. I recommend since there's already a 4 on the bottom, just do 4 * 4 there. Then you see there is a 4 on the denominator while there are double 4's on the numerator. Then you just cross one 4 on the denominator and one on the numerator to simplify it.
Then all there is is 50 + 4 = 54
So 54 is our answer.
Answer:
Step-by-step explanation:
10m + n^2/4 (m=5 , n=4)
(10*5) + (4^2/4) =
