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

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

An airplane has a wingspan of 20 feet and a length of 15 feet. If the model of this airplane has a wingspan of 8 inches, what is the length of this model?
Answer:
The length of the model is 6 inches.
Step-by-step explanation:
The wingspan of the airplane and length of the airplane are a ratio of 4:3
The model is also supposed to be 4:3.
4:3 x 2 = 8:6
Or, 20x12=240
240/8=30
15x12=180
180/30=6.

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.

I NEED HELP WITH GEOMETRY
Answer:
a) 136 square units
b) 92 square units
Step-by-step explanation:
A)
The triangle is worth:
16 * 16 / 2 = 128 + 16 * 16 / 2 = 128 = 256.
There is a rectangle in the middle with deletes 120 square units from 256.
256 - 120 = 136, so the first shape equals 136 square units.
B)
The smaller shaded triangles is 32 square units because 8 * 8 / 2 = 32.
The biggest one would be 15 * 8 / 2 = 60 square units.
32 + 60 = 92 square units.
Hope this helped!
Answer:
a. 136 [tex]units^{2}[/tex]
b. 92 [tex]units^{2}[/tex]
Step-by-step explanation:
a. Find the area of the triangle and the area of the rectangle, then subtract the area of the rectangle by the triangle.
Area of triangle: bxh / 2 = 32x16 / 2
= 512 / 2
= 256
Area of rectangle: bxh = 20 x 6
= 120
Total area: 256 - 120 = 136 [tex]units^{2}[/tex]
b. Just like a., find the area of the white triangle and the rectangle, then subtract the area of the triangle by the rectangle.
Area of triangle: bxh / 2 = 23x8 / 2
= 184 / 2
= 92
Area of rectangle: bxh = 23 x 8
= 184
Total area: 184 - 92 = 92 [tex]units^{2}[/tex]

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.

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
