Answer:
5/42
Step-by-step explanation:
7x - 3/2 = -2/3 (Take -3/2 to the other side so it becomes +3/2)
7x = -2/3 +3/2 (Add the two fractions)
7x = 5/6 (7 is taken to the other side so 5/6 ÷ 7)
x = 5/42

find RT plz help im bad at this type of math
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
According to above diagram :
RT = RS + ST
that is :
[tex]2x + 75 = 4x + 107 + 12[/tex][tex]2x - 4x = 119 - 75[/tex][tex] - 2x = 44[/tex][tex]x = - 22[/tex]now, RT = 2x + 75
[tex](2 \times - 22) + 75[/tex][tex] - 44 + 75[/tex][tex]31[/tex]hence , RT = 31 units
Answer:
RT = 31
Solve for x:
[tex]x=-22[/tex]
Step-by-step explanation:
==>> The sum of the line is RST
[tex]4x+107+12=RST[/tex]
==>> Since [tex]RST = 2x + 75[/tex], the equation will newly become [tex]4x+107+12=2x+75[/tex]
--
To find [tex]4x+107[/tex], we need to find the x.
==>> [tex]x=-22[/tex]
-- Lets check our work
==>> [tex]4(-22) = -88[/tex]
[tex]-88 + 107 = 19 [RS = 19][/tex]
[tex]RS + ST = 19 + 12 =[/tex] 31
--
[tex]2(-22) = -44[/tex]
[tex]-44 + 75 =[/tex] 31
31 = 31

Which is a solution for 4 x + 8 = 3 x + 14?
Answer:
x=6
Step-by-step explanation:
Step 1:
Subtract 3x from both sides:
4x + 8 - 3x = 3x + 14 - 3x
x + 8 = 14
Step 2:
Subtract 8 from both sides:
x + 8 - 8 = 14 - 8
x = 6

The measures of the exterior angles of a heptagon are x°, 2x°, 3x°, 5x°, 7x°, 8x°, and 10x°. Solve for x.
Answer:
x = 10
Step-by-step explanation:
Exterior angles in any polygon always measure 360°
x + 2x + 3x + 5x + 7x + 8x + 10x = 360°
36x = 360
x = 360/36

Answer: - 4d
Step-by-step explanation:
In the equation, there's an invisible 1 in front of the first d, so let's add that.
1d - 2d - 3d
Since all the terms in the above equations are like terms, we would focus on only subtracting. We would first subtract 2d from 1d.
- 1d - 3d
We then subtract 3d from - 1d. This would give us our answer.

Step-by-step explanation:
The relevant trig relations are summarized by the mnemonic SOH CAH TOA. This means ...
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
So, for each triangle, determine the relationships of the given sides to the given angle: adjacent, opposite, or hypotenuse. Then write and solve the equation using one of the above templates.
Evaluate each of the expressions below using the given value.

Find the measure of the indicated angles.show work.complete sentence a. m<QRP = ____
b. m<QRX = ____
The measure of m<QRX and m<QRP are 129 and 51 degrees respectively.
The sum of the interior angle of a triangle is 180 degrees, hence;
m<QPR + m<QRP + M<PQR = 180
Substitute the given parameters
49 + m<QRP + 80 = 180
m<QRP + 129 = 180
m<QRP = 180 - 129
m<QRP = 51 degrees
The sum of interior angle is equal to the exterior
m<QPR + M<PQR = m<QRX
m<QRX = 49 + 80
m<QRX = 129 degrees
Hence the measure of m<QRX and m<QRP are 129 and 51 degrees respectively.

Find the value of x. Find the measures of the two supplementary angles
Answer:
x = 32
<1 = 102 degrees
<2 = 78 degrees
Step-by-step explanation:
3x + 6 + 2x + 14 = 180
5x + 20 = 180
5x = 180 - 20
x = 160/5
x = 32
3(32) + 6 = 102 degrees
180 - 102 = 78 degrees
