Answer:
The answer is Letter A.
Step-by-step explanation:
Find the value of x.
[tex]2x + 50 = x + 76 \\ 2x - x = 76 - 50 \\ x = 26[/tex]
Substitute x to the equation for angle 2.
[tex]2x + 50 \\ = 2(26) + 50 \\ = 52 + 50 \\ = 102[/tex]

Answer:
A) 102
Step-by-step explanation:
Alternative Exterior Theorem: If two parallel lines are cut by a transversal, then the pairs of alternative exterior angles are congruent.
Because of this theorem, we know that <2 and <8 are congruent, so we can set these equations to be equal to each other, like so:
2x + 50 = x + 76
Then, we need to find the x value, so solve from there.
2x + 50 = x + 76
x + 50 = 76 [Subtract x from both sides of the equal sign]
x = 26 [Subtract 50 from both sides of the equal sign]
So now that we have our x value, all we have to do is plug in that value to the <2 equation.
2x + 50
2(26) + 50
52 + 50
102

Answer:
I can't add picture for some reason so u have to read explanation :(
Step-by-step explanation:
First, turn everything into an improper fraction.
you get 11/3 x 9/2 ÷ 5/4
Next, according to PEMDAS, you multiply first and you get
33/2. DIvide that by 5/4 so
33/2 ÷ 5/4
So you get 33/5 or as a mixed fraction, 6 3/5

Lucia deposits $44.60 into her bank account on Tuesday Morning. Tuesday afternoon, she withdraws to $26.30 and $21.30. Does Luisa have more or less money on Tuesday night than she did on Monday night? Does this equation tell whether Luisa has more or less money on Tuesday night than Monday night? Explain.
Answer:
Less than
Step-by-step explanation:
Using the data from the question, we can create the following equation to solve this...
44.60 - (26.30 + 21.30) = x
44.60 - (47.60) = x
-3 = x
As you can see Lucia withdrew more money than what she actually deposited which means that her account balance on Tuesday Night is less than what it was on Monday night before the initial deposit. This can all be seen using the above equation which is designed.

NEED HELP! A line has a slope of 9/7 and a y-intercept of 1/3. Which of the following is an equation of the line?
A 27x - 21y = -7
B 27x + 21y = 1
C 9x + 7y = 3
D 7x - 9y = -3
Please show work so I could understand this!
Answer:
A
Step-by-step explanation:
Take a look at the slope-intercept form of the equation .
[tex]y=mx+c[/tex]
Slope of 9/7 and y-intercept of 1/3 means replace m which is slope and c is the y-intercept which becomes
[tex]y=\frac{9}{7}x+\frac{1}{3}[/tex]
now we take LCM of 7 and 3 which becomes
[tex]y=\frac{27x+7}{21}[/tex]
and then,
[tex]21y=27x+7[/tex]
so A is our Answer
if arrange the equation accordingly

Answer:
See Explanation
Step-by-step explanation:
1.
Given
[tex]y = 6x - 11[/tex]
[tex]-2x - 3y = -7[/tex]
Solve for x and y
In the first equation, we have: [tex]y = 6x - 11[/tex]
Substitute [tex]6x - 11[/tex] for [tex]y[/tex] in the second
[tex]-2x - 3y = -7[/tex]
[tex]-2x - 3(6x - 11) = -7[/tex]
[tex]-2x - 18x + 33 = -7[/tex]
[tex]-20x+ 33 = -7[/tex]
[tex]-20x= -7-33[/tex]
[tex]-20x= -40[/tex]
Divide through by -1
[tex]20x = 40[/tex]
[tex]x = 40/20[/tex]
[tex]x = 2[/tex]
Recall that:
[tex]y = 6x - 11[/tex]
[tex]y = 6 * 2 - 11[/tex]
[tex]y = 1[/tex]
2,
Given
[tex]-3x - 3y = 3[/tex]
[tex]y = -5x - 17[/tex]
In the second equation, we have: [tex]y = -5x - 17[/tex]
Substitute [tex]-5x - 17[/tex] for [tex]y[/tex] in the first equation
[tex]-3x - 3y = 3[/tex]
[tex]-3x - 3(-5x - 17) = 3[/tex]
[tex]-3x + 15x + 51 = 3[/tex]
[tex]12x + 51 = 3[/tex]
[tex]12x=3 - 51[/tex]
[tex]12x=-48[/tex]
[tex]x = -48/12[/tex]
[tex]x = -4[/tex]
Recall that: [tex]y = -5x - 17[/tex]
[tex]y = -5 * -4 - 17[/tex]
[tex]y = -3[/tex]
3. Given
[tex]-4x + y = 6[/tex]
[tex]-5x - y = 21[/tex]
Add both equations to eliminate y
[tex]-4x - 5x + y - y = 6 + 21[/tex]
[tex]-9x= 27[/tex]
Solve for x
[tex]x = 27/-9[/tex]
[tex]x = -3[/tex]
Substitute -3 for x in the first equation: [tex]-4x + y = 6[/tex]
[tex]-4 * -3 + y = 6[/tex]
[tex]12 + y = 6[/tex]
[tex]y = 6 - 12[/tex]
[tex]y = -6[/tex]
4. Given
[tex]-7x - 2y = -13[/tex]
[tex]x - 2y = 11[/tex]
Make x the subject in the second equation
[tex]x - 2y = 11[/tex]
[tex]x = 11 + 2y[/tex]
Substitute 11 + 2y for x in the first equation
[tex]-7x - 2y = -13[/tex]
[tex]-7 (11 + 2y) - 2y = -13[/tex]
[tex]-77 -14y - 2y = -13[/tex]
[tex]-77 -16y = -13[/tex]
[tex]-16y = -13 + 77[/tex]
[tex]-16y = 64[/tex]
[tex]y = 64/-16[/tex]
[tex]y = -4[/tex]
Substitute -4 for y in [tex]x = 11 + 2y[/tex]
[tex]x = 11 + 2 * -4[/tex]
[tex]x = 11 -8[/tex]
[tex]x = 3[/tex]
5. Given
[tex]-2x + 6y = 6[/tex]
[tex]-7x + 8y = -5[/tex]
Multiply the first equation by 7 and the second by - 2 to eliminate x
The first
[tex]7(-2x + 6y = 6)[/tex]
[tex]-14x + 42y =42[/tex]
The second
[tex]-2(-7x + 8y = -5)[/tex]
[tex]14x - 16y = 10[/tex]
Add the resulting equations
[tex]-14x + 42y =42[/tex]
[tex]14x - 16y = 10[/tex]
------------------------------
[tex]-14x + 14x + 42y - 16y = 42 + 10[/tex]
[tex]42y - 16y = 42 + 10[/tex]
[tex]26y = 52[/tex]
Solve for y
[tex]y = 52/26[/tex]
[tex]y = 2[/tex]
Substitute 2 for y in [tex]-2x + 6y = 6[/tex]
[tex]-2x + 6 * 2 = 6[/tex]
[tex]-2x + 12 = 6[/tex]
[tex]-2x = 6 -12[/tex]
[tex]-2x = -6[/tex]
Solve for x
[tex]x = -6/-2[/tex]
[tex]x = 3[/tex]
Charlie is reading about animal hearts in a kids science magazine. He learns that a nestling (young) Striped Horned Owls heart weighs approximately 1.072 grams and blue whale's heart weighs 400 lbs. He is eager to share what he learned with his friends over lunch the next day and tells them that a blue whale's heart and a striped horned owl's heart are two orders of magnitude apart. Do you agree with Charlie's statement? Explain.
Answer:
Charlie's statement is incorrectStep-by-step explanation:
Given that the owls heart weighs 1.072 grams
and the Whale's heart weighs 400lbs
let us convert from pounds to grams to have a uniform unit
400lbs = 181,437grams
Now when two readings or quantities are two orders apart it means that they differ by a factor of 100
let us solve for the difference between the two hearts
181,437grams- 1.072 grams= 181 435.928 grams
the difference is more than two orders, hence the statement is not correct

1. Angle 1 congruent to Angle 3, Angle 2 congruent to Angle 4 ( top row last box in answer choices)
2. Reflexive Property of Congruence
3. Angle DGF congruent to Angle DEF
Step-by-step explanation:
Opposite sides of a parallelogram are parallel , so angle 1 ≅ angle 3 and angle 2 ≅ angle 4 because they are alternate interior angles . By the reflexive property of congruence DF ≅ DF . Therefore , △ DGF ≅ △ DEF by the ASA congruence postulate . That means DE ≅GF and DG ≅EF by CPCTC .
