Answer:
8
Step-by-step explanation:
Set 3n-1=5n-7.
Solve.
n=3.
Plug in 3 to 5n-7.
QR=8
Answer:
QR=8
Step-by-step explanation:
so using the fact that the two triangles are congruent, we can determine:
5n-7=3n-1
5n-6=3n
2n-6=0
n=3
so we replace all n in 5n-7 with three
5x3-7
15-7

Answer:
0
Step-by-step explanation:
7c =
7(0) = 0
hope you understand
Answer:
since the c is 0.. then substitute c as 0 in 7c...
hence the equation will be 7(0)...
equals to 7×0
the answer is 0
Find three consecutive even integers such that the product of the first and second is 8 more than 38 times the third.
Answer:
40, 42 and 44
Step-by-step explanation:
Mark these even consecutive integers as (2n-2), 2n and (2n+2)
Note that since they are integers, n > 0 and 2n is always even
Writing the equation
(2n-2) * 2n = 38 * (2n+2) + 8
// divide both sides by 2
(2n-2) * n = 19 * (2n+2) + 4
[tex]2n^{2}[/tex] - 2n = 38n + 38 + 4
[tex]2n^{2}[/tex] - 2n - 38n - 38 - 4 = 0
[tex]2n^{2}[/tex] - 40n - 42 = 0
// divide both sides by 2
[tex]n^{2}[/tex] - 20n - 21 = 0
// rewrite the equation
[tex]n^{2}[/tex] + n - 21n - 21 = 0
n * (n+1) - 21n - 21 = 0
n * (n+1) - 21 * (n+1) = 0
(n+1) * (n-21) = 0
// separate the two possible cases
n + 1 = 0 and n - 21 = 0
n = -1 n = 21
Note that here n has to be an integer, so case n = -1 can't be a solution. Therefore we use n = 21
Calculating the consecutive even integers
2n - 2 = 2 * 21 - 2 = 40
2n = 2 * 21 = 42
2n + 2 = 2 * 21 + 2 = 44

Find the missing angle measure. PLEASE HELP ASAP
Answer:
Angle 1 is 57 degrees
Angle 3 is 57 degrees
Angle 4 is 123 degrees
Step-by-step explanation:
Cause a straight line is 180 degrees and if angle 2 is 123 degress then angle 3 is 57 degrees and i got that by Subtracting 180-123 =57
Then for angles one you do the same maththat you do for finding angle 3
Then for angles 4 subtract 180-57=123

Segment AB is being dilated with the center at the origin. The image of A, point A prime, has coordinates of (3.2, 6.4). What is the scale factor of the dilation and the coordinates of point B prime?
Step-by-step explanation:
The location of A is 3.2
The location of A' is 6.4
A represent pre image A' represent the new image.
The scale factor of A to A' is 2 since 3.2 x 2 =6.4
Since you didnt provide B coordinates, just multiply 2 by the B coordinate to find the B prime coordinate.
Answer: A.)The scale factor is 0.8 and the coordinates of point B prime are (–3.2, –4.8).

CAN SOMEONE PLEASE HELP THIS IS DUE AT MIDNIGHT (I’ll give brainlist)
Answer:
d° = 62°
e° = 90°
f° = 27°
g° = 27°
h° = 118°
j° = 62°
k° = 63°
Step-by-step explanation:
The relationship between the given angles are;
k° = 63° (Vertically opposite angles)
63° + f° = 90° (Given complementary angles)
∴ f° = 90° - 63° = 27°
f° = 27°
g° = f° (Vertically opposite angles)
∴ g° = f° = 27°
g° = 27°
e° + 63° + f° = 180° (The sum of angles on a straight equals 180°)
∴ e° = 180° - (63° + r°) = 180° - (63° + 27°) = 90°
e° = 90°
h° = 118° (Vertically opposite angles)
118° + d° = 180° (The sum of angles on a straight equals 180°)
∴ d° = 180° - 118° = 62°
d° = 62°
j° = d° (Vertically opposite angles)
∴ j° = d° = 62°
j° = 62°
Write the equation of the line graphed below
Answer:
y = 5/8x + 12
Step-by-step explanation:
Slope = change in y/change in x
slope = 5/8
Using y = mx + b find b.
y = 5/8x + b
-2 = 5/8(-4) + b
b = 1/2
y = 5/8x + 12
good luck, i hope this helps :)

How do you know
the quotient of 639 /
6 is greater than
100 before you actually divide
Answer:
because since the question is 639 / 6
we immediately know that 600 / 6 is 100
639 / 6 = 106.5
Answer:
You just need a little conversion to get the answer.
[tex]\frac{639}{6}=\frac{600}{6}+\frac{39}{6}\\ = 100+\frac{39}{6} >100[/tex]

The hypotenuse of a right triangle measures 18 cm and one of its legs measures 16 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer: 8.25cm
Step-by-step explanation:
Use Pythagorean's Theorem for a right triangle:
[tex]a^2+b^2=c^2[/tex]
'A' and 'B' being the legs and 'C' being the hypotenuse.
[tex]16^2+b^2=18^2\\256+b^2=324\\b^2=68\\b=\sqrt{68}=8.25cm[/tex]
b) If f(2x - 3) = 4x + 5, then find f(x) and f(-2).
c) If f(x) = 7* then prove that
f(m + n + p) = f(m) . f(n) f(p)
pls solve at least 1 only if u know
f(2x-3)=4x+5
Let, 2x-3=g
x=(g+3)/2
So,f(2{g+3}/2 -3)=4(g+3)/2 + 5
f(g)=2g+11
So,f(x)=2x+11
f(-2)=7 ##
Answer:
f(2x - 3) = 4x + 5
f(2x-3)=2(2x-3)+11
f(x)=2x+11
f(-2)=2×-2+11=-4+11=7
The sides of a triangle formed a geometric progression with a ratio r. For what values of r, it is possible?
Answer:
ok so i really shouldnt get points for this, but i wanted to help. The person who solved the problem here: https://math.stackexchange.com/questions/2911546/suppose-the-sides-of-a-triangle-form-a-geometric-progression-with-common-ratio-r is correct, but it is not very clear. Basically, he rounded to the third decimal point (since a sqrt has infinate decimals), and this might have been what got you the wrong answer. Basically the important thing is that r has to be between the (-1+√5)/2 and (1+√5)/2, or (-1+√5)/2 < r < (-1+√5)/2

The sum of three numbers is 212 .If the ratio of the first to the second is 13:16 and that of the second to the third is 2:3 then find the numbers.`
Given:
The sum of three numbers is 212 .
The ratio of the first to the second is 13:16 and that of the second to the third is 2:3.
To find:
The unknown numbers.
Solution:
We have,
First : Second = 13:16
Second: Third = 2:3
We need to combine these ratios, to get a single ratio for all three numbers.
Second: Third = 2×8:3×8 = 16:24
Now,
First: Second: Third = 13:16:24
Let the first, second and third numbers are 13x, 16x and 24x respectively.
[tex]13x+16x+24x=212[/tex]
[tex]53x=212[/tex]
[tex]x=\dfrac{212}{53}[/tex]
[tex]x=4[/tex]
So, the numbers are,
[tex]First=13x[/tex]
[tex]First=13(4)[/tex]
[tex]First=52[/tex]
Similarly,
[tex]Second=16x[/tex]
[tex]Second=16(4)[/tex]
[tex]Second=64[/tex]
And,
[tex]Third=24x[/tex]
[tex]Third=24(4)[/tex]
[tex]Third=96[/tex]
Therefore, the three unknown numbers are 52, 64, 96.
