64
because the small triangle at the top is isoscel and has the base angles BDE and BED = (180 -48)/2 =66
angle BDE is congruent to DAC = 66, because 2 || BE and AC are cut by transversal BA
angle ADC = 180 -50 -66 = 64

C: 42x - 8y - 5.3
D: 84x - 16y - 5.3
Answers
Answer:the answer is a
Step-by-step explanation:
The expression 2(14x - 3y + 28x + 12.2 - 5y - 17.5) is equivalent to the expression 84x - 16y -10.6 option (A) is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have an expression:
= 2(14x - 3y + 28x + 12.2 - 5y - 17.5)
= 28x - 6y + 56x + 24.4 - 10y - 35
Adding like terms
= 84x - 16y -10.6
Thus, the expression 2(14x - 3y + 28x + 12.2 - 5y - 17.5) is equivalent to the expression 84x - 16y -10.6 option (A) is correct.

Instructions to care for a plant say to water it with 3/4 cup of water every day. The plant has been getting 25% too much water. How much water has the plant been getting? PLZZZZZZZ HELP ME!!
Answers
Answer: 0.9375 or 15/16 cup of water
Step-by-step explanation:
The plant has been getting 25% too much water which means that it has been getting 25% more than 3/4.
= 25% * 3/4
= 0.1875 cup of water
Water plant has been getting;
= 3/4 + 0.1875
= 0.9375 or 15/16 cup of water

Look at the question and the student work below. In complete sentences, describe the mistake the student made and explain how to answer the question properly. Be sure to include a description of the algebraic steps required to solve for x and find the correct measure of the indicated angle.
Answers
Answer:
The equations should have been added up to equal 180 instead of being set to equal each other. The two are supplementary angles, which can be seen due the rule that a pair of interior angles on the same side of the transversal is supplementary. To fix this issue from the work that they did, they should subtract the 140 from 180, so the correct measure of DKH is actually 40 degrees.

Consider the system of equations shown below. y = negative 5 x + 1. y = negative 5 x + 10 When graphed, the system consists of two lines that will never meet, no matter how far they are extended. Why are the lines parallel? The linear equations have the same slope and y-intercept. The linear equations have different slopes and y-intercepts. The linear equations have the same slope but different y-intercepts. The linear equations have different slopes but the same y-intercept.
Answers
The reason why both graphs are parallel because they have the same slope but different y-intercept.
Think about it. If both graphs have same slope and same y-intercept. The graph will intercept each others infinitely.
Then if we change the y-intercept into any numbers that aren't the same as another equations for ex.
y = -5x+1 and y = -5x+10
then we will get the parallel graph. Or if you solve the equation, the equation will not be true, thus giving the graph parallel.
But if it is y = -5x+1 and y = -5x+1 which both are the same graph. Then the graph will intercept each others infinitely. Or if we solve the equation, we will get 0 = 0 which makes the equation true for all real numbers.
Therefore, the reason why both graphs are parallel is because that they have the same slope but different y-intercept.
That's all.

There are 5280 feet in a mile and 60 minutes in an hour (needless to say). How fast is a car going 30 miles per hour traveling in feet per minute?
(Please help me)
Answers
Answer:
2640 feet in a minute.
Step-by-step explanation:
Since the car is going 30 miles per hour, and there are 5280 feet in one mile, you would multiply 30 by 5280.
30 * 5280 = 158400
So 154800 feet = 30 miles.
Since you want to find out how fast a car going 30 miles per hour is traveling in feet per a minute, you would divide 154800 feet by 60, since there are 60 minutes in an hour.
154800 / 60 = 2640.
So 2640 feet in a minute.
If you want to check this, you can do 2640 * 60, which indeed equals 154800.
Hope this helps.

Most staircases in use today have 9−inch treads and 8 12 −inch risers. What is the slope of a staircase with these measurements? Give your answer as a fraction or rounded to four decimal places, if necessary
Answers
Answer:
The value is [tex]m = 0.9022[/tex]
Step-by-step explanation:
From the question we are told that
The length of the treads is [tex]a = 9 \ inch[/tex]
The length of the risers is [tex]b = 8.12 \ inch[/tex]
Generally the slope of the staircase is
[tex]m = \frac{b}{a}[/tex]
=> [tex]m = \frac{8.12}{9}[/tex]
=> [tex]m = 0.9022[/tex]

Step-by-step explanation:
[tex]3 \frac{3}{4} - 2 \frac{9}{16}[/tex]
Convert into improper fractions:
[tex]3 \frac{3}{4} = \frac{15}{4}[/tex] and [tex]2 \frac{9}{16} = \frac{41}{16}[/tex]
LCD is 16 so multiply 15/4 by 4/4 to get 60/16

You want to purchase a new bike that costs $142.68. To save for the bike, you mow your neighbor's yard for $40 each week. How much money will you have left over if you buy the bike after saving for 4 weeks?
Answers
The amount of money left after purchasing the bike is $17.32
How to calculate the amount of money left ?The cost of the new bike is $142.68
I need to save for the new bike and i decided to mow the neighbour's yard
The money paid is $40, this will be done for 4 weeks
At the end of the four weeks, the money i will get can be calculated as follows
= 40 × 4
= 160
To calculate the money left, let's subtract the cost of the bike from 160
= 160 - 142.68
= 17.32
Hence the amount of money left after buying the bike is $17.32

If using the method of completing the square to solve the quadratic equation
x2 + 11x + 30 = 0, which number would have to be added to "complete the
square"?
Answers
Answer:
The number to add is (11/2)^2 = 121/4
Step-by-step explanation:
Here, we want to know the number that will complete the square
We rewrite the equation as follows;
x^2 + 11x = -30
x^2 + 11x + (11/2)^2 = -30 + (11/2)^2
x^2 + 11x + 121/4 = -30 + 121/4

If 2 -5=5, then 4x -6=14.
If 4x--6=14, then 2x-5=5.
If 2x -- 5≠5, then 4x--6≠14.
If 4x - 6≠14, then 2x - 5≠5.
Answers
Answer:
We conclude that:
If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.Step-by-step explanation:
We know that the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p".In other words, it is symbolically represented as:
' ~q ~p is the contrapositive of p q 'For example, the contrapositive of "If there is a snow outside, then they cancel the event" is "If they do not cancel the event, then it would not be snow outside."
Given
p: 2x -5=5q: 4x-6=14As the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p
Therefore, we conclude that:
If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.
