Answer:
79
Step-by-step explanation:
Sense all the lines are straight, and will never cross, then adjacent angles must always add up to 180 degrees. 3 and 4 are adjacent. Thus they must add up to 180. So set up as 101 + x = 180. x=180 - 101, and find that x = 79. Plug x back into check. 101 + 79 = 180. and 180= 180. The answer is 79 degrees.

Answers
Answer:coo
Step-by-step explanation:Cooke.
The amount of paint which will Becca need to paint the birdhouse in 1 coat is 418 cm².
What is surface area?Surface area of any solid or the 3 dimensional body is the area of each faces by which the solid body is enclosed.
The surface area of rectangular prism can be given as,
[tex]SA=2(wl+hl+hw)[/tex]
Here, (w) is the width, (h) is the height and (l) is the length of the prism.
Becca is painting a birdhouse. The shape of the birdhouse is similar to rectangular prism with dimensions as, height of 13cm, a width of 5 cm, and a length of 8cm.
Now Becca wants to paint this house using 1 coat. As this paint has to be cover each surface of the house. Thus the amount of total paint should be equal to the surface area of the house.
Here, the dimensions of house is as, height of 13cm, a width of 5 cm, and a length of 8cm. Therefore the surface area of it is,
[tex]SA=2(5\times8+13\times8+13\times5)\\SA=418\rm cm^2[/tex]
Hence, the amount of paint which will Becca need to paint the birdhouse in 1 coat is 418 cm².

question: solve the solution using substitution.
Answers
Answer:
x = -3
y = -8
Step-by-step explanation:
2y = x - 13
3x = y - 1; let y = 3x + 1
substitute to solve for 'x':
2(3x + 1) = x - 13
6x + 2 = x - 13
5x + 2 = -13
5x = -15
x = -3
solve for 'y':
3(-3) = y - 1
-9 = y - 1
-8 = y
Answer:
(-3,-8)
Step-by-step explanation:
Get one of the variables by themself.
3x = y-1
y = 3x+1
Plug that equation into the other one
2(3x+1) = x-13
Distribute the 2 to 3x+1
6x+2 = x-13
Combine like terms
6x+2 = x-13
-x -x
5x+2 = x-13
-2 -2
5x = -15
Divide by 5 on both sides
5x = -15
÷5 ÷5
x = -3
Find y
3(-3) = y-1
-9 = y-1
+1 +1
y = -8

8 times a certain number is added to 5 times a second number to give 184.the first number minus the second number is -3.find these number .
Answers
Answer:
The numbers are 13 , 16
Step-by-step explanation:
First number be x
Second number be y
x - y = -3 --------------------(I)
x = -3 +y
8x + 5y = 184 ---------------(II)
substitute x = -3 + y in equation(I)
8*(-3 + y) + 5y = 184
-24 + 8y + 5y = 184
-24 + 13y = 184
13y = 184 + 24
13y = 208
y = 208/13
y = 16
Plugin y = 16 in (I)
x - 16 = -3
x = -3 +16
x = 13
