Answer:
a = [tex]\frac{e+d}{b+c}[/tex]
Step-by-step explanation:
To isolate the a, the first thing I would do is bring the d to the other side of the equation, remember to switch the sign. This would give me a(b+c) = e+d. Next, in order to get rid of the (b+c), bring it to the other side by dividing since it is attached to the a variable by multiplication. This leaves me with a = e+d / b+c. Make sure not to distribute, this would duplicate your a variable.

What theorem is used to determine if the base angles of a triangle are congruent?
Answer:
Isosceles Triangle Theorem
Step-by-step explanation:
An isosceles triangle is a tringle that has a pair of congruent sides and a pair of congruent angles. If the triangle has two congruent angles its isosceles. So therefore, you would use the Isosceles Triangle Theorem.
The Isosceles triangle theorem is used to determine if the base angles of a triangle are congruent.
What is base angles of triangle?"The angles that have the base as one of the side of triangle. "
What is isosceles triangle?"It is a triangle that has any two sides equal in length and angles opposite to equal sides are equal in measure."
For given question,
We need to find the theorem that is used to determine if the base angles of a triangle are congruent.
We know that the Isosceles triangle theorem states that 'If two sides of a triangle are congruent, then angles opposite those sides are congruent.'
In isosceles triangle any two sides of the triangle are equal in length.
If we draw the angle bisector for an angle between two equal sides, then we get two triangles.
Then by SAS congruence postulates we can prove that both the triangles are congruent and so the base angles of a triangle are congruent.
Therefore, an Isosceles triangle theorem is used to determine if the base angles of a triangle are congruent.

On an examination 35% of the students passed and 455 failed. How many students took the examination?
Answer:
700 students
Step-by-step explanation:
455/.65= 700 students
Answer:
700
Step-by-step explanation:
Total no of students failed = 65% (100-35% who passed)
so
455/65=7, which is equal to 1% of total strength.
Total no of students passed is 35%, So
7*35=245.
So Total Students is equal to
245+455= 700.
slope=−4/3, y-intercept = 3
Answer:
The equation is y = [tex]-\frac{4}{3}[/tex] x + 3
Step-by-step explanation:
The form of the equation is y = m x + b, where
m is the slopeb is the y-intercept∵ The slope of the line is [tex]-\frac{4}{3}[/tex]
∴ m = [tex]-\frac{4}{3}[/tex]
→ Substitute it in the form of the equation above
∴ y = [tex]-\frac{4}{3}[/tex] x + b
∵ The y-intercept = 3
∴ b = 3
→ Substitute it in the equation above
∴ y = [tex]-\frac{4}{3}[/tex] x + 3
∴ The equation is y = [tex]-\frac{4}{3}[/tex] x + 3
At the tailor shop, it costs $6.59 to shorten a pair of pants and 3 times as much to mend a dress. Choose the answer that ocrrectly ocmpletes the statement.
It would cost Lisa
[ Select ]
to shorten one pair of pants and mend one dress.
Answer:
It would be $26.36
Step-by-step explanation:
all you must do is 6.59^3+6.59 aka 6.59^4 since it told you that it's 6.59 to shorten a pair of pants but its 3 TIMES more to mend a dress.
answer:
it would cost lisa $6.59 to shorten one pair of pants and $19.77 mend one dress.
explanation:
6 x 3 = 18
18 + .59 = 18.59
18.59 + .59 = 19.18
19.18 + .59 = 19.77

wrtie an equation in slope-intercept form for the line that passes through the point (1,-1) and is parallel to the line whose equation is y= 2x+5
Answer:
y = 2x - 3
Step-by-step explanation:
Since the line needs to be parallel, you can take the slope of the other equation and input it into y = mx + b:
y = 2x + b
Next, to have it intercept at the given coordinates, input the coordinates into the equation and solve for b:
-1 = 2 ( 1 ) + b
-1 = 2 + b
-1 - 2 = b
-3 = b
Now input the "b" value into the equation and you have the answer:
y = 2x - 3

A combination lock is opened with the correct sequence of three numbers between 0 and 49 inclusive. If a number can be used more than once, what is the probability of guessing those three numbers and opening the lock with the first try? (Write answer as a simplified fraction
Answer:
125,000
Step-by-step explanation:
Given that :
Sequence of three numbers chosen from 0 to 49 inclusive
Since numbers can be repeated ; hence numbers do not have to be different ;
Number of digits between (0 - 49 inclusive) = 50 digits.
Thus, there are equal number of possible choices for each of the three numbers, which is equal to the Number of digits :
1st number = 50
2nd = 50
3rd = 50
Hence,
(50³). = 50 * 50 * 50 = 125,000

Which pair of angles is supplementary?
∠RXZ and ∠YXZ
∠PXQ and ∠RXS
∠YZX and ∠UZT
∠WZX and ∠XYZ
*see attachment below for the diagram being referred to
Answer:
∠RXZ and ∠YXZ
Step-by-step explanation:
Supplementary angles are angles whose sum gives us 180°.
Let's consider each pair of angles given as options and see which of them are supplementary angles considering the given diagram:
Option 1: ∠RXZ and ∠YXZ.
∠RXZ and ∠YXZ are angles on a straight line, and they form a linear. A linear pair = 180°. Therefore, ∠RXZ and ∠YXZ pair is supplementary.
Option 2: ∠PXQ and ∠RXS do not form a linear pair, neither are they angles in a straight line, therefore, the angle pair ∠PXQ and ∠RXS, is not supplementary.
Option 3: ∠YZX and ∠UZT.
∠YZX and ∠UZT are vertical angles. Therefore, the angle pair ∠YZX and ∠UZT is not supplementary.
Option 4: ∠WZX and ∠XYZ.
There's no special relationship between ∠WZX and ∠XYZ, other than being angles of ∆XYZ. Therefore, the angle pair ∠WZX and ∠XYZ, is not supplementary.
Answer:
A. ∠RXZ and ∠YXZ

Jonshelle is developing a new bread recipe. The relationship between cups of water, w, and cups of flour, f, is w = 7/10f. What is the scale factor of water to flour?
Answer:
The scale factor of water to flour represents the proportionality ratio, that is, [tex]k = \frac{7}{10}[/tex].
Step-by-step explanation:
According to the statement, we know that it exists a linear relationship between cups of water ([tex]w[/tex]) and cups of flour ([tex]f[/tex]). That is:
[tex]w = k\cdot f[/tex] (Eq. 1)
Where [tex]k[/tex] is the proportionality ratio, measured in cups of water per cup of flour.
Therefore, the scale factor of water to flour represents the proportionality ratio, that is, [tex]k = \frac{7}{10}[/tex].
