Answer:
x = 30 degrees
Step-by-step explanation:
Okay so we start by noticing that the two pointed out vertices = 180 degrees. So we have the following equation.
(x + 12) + (3x + 48) = 180
If you combine them you get:
4x + 60 = 180
Subtract 60 from both sides..
4x = 120
Divide both sides by 4..
x = 30
And there's your answer!

Answers
Answer:
x=4.875
y=-0.25
Step-by-step explanation:
4x – 2y = 10
2x-y=10
y=2x-10
4x + 6y = 18
2x+3(2x-10)=9
8x=39
x=4.875
y=2(4.875)-10

Step-by-step explanation:
The required number of coins are would only by quarters so that 12 coins shows the values of $3.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
dime = $0.1
quarter = $0.25
Now,
Let the number of dimes be x and number of quarter be y,
x + y = 12
x = 12 - y - - -- -(1)
According to the question,
0.1x + 0.25y = 3 -- - -(2)
y = 12
Now,
x = 0
Thus, the required number of coins are would only by quarters so that 12 coins shows the values of $3.

log 3 + log x - log(x + 1) = log 2
Please please help
Answers
Answer:
x = 2
Step-by-step explanation:
Given the equation as;
log 3 + log x - log(x + 1) = log 2
collect like terms
log x - log(x + 1) = log 2-1og 3
Re-write the equation by applying laws of logarithms in that when you subtract logs you divide the numbers/terms. This will give
log [ x / x+1 ] = log [2/3]
Cancel log on both sides to remain with;
x/ x+1 = 2/3
Apply cross-product
3{x} = 2{x+1}
3x = 2x + 2
3x-2x = 2

What is a midpoint?"The midpoint of a segment can be considered to be the average of its endpoints."
Given end points of CD
C (-2, -4) and D (6, 2)
The coordinates of the midpoint of CD = ?
Formula to find the midpoint of CD
Midpoint of CD = [tex](\frac{x_{1}+x_{2} }{2} , \frac{y_{1}+y_{2} }{2} )[/tex]
C = ([tex]x_{1}[/tex], [tex]x_{2}[/tex]) = (-2, -4) and D = ([tex]y_{1}[/tex], [tex]y_{2}[/tex]) = (6, 2)
Midpoint of CD = [tex](\frac{-2+6}{2}, \frac{-4+2}{2} )[/tex]
= [tex](\frac{-4}{2} , \frac{-2}{2} )[/tex]
= [tex](2, -1)[/tex]

Manufacturing a company is designing a new rectangular shipping box that must have a
volume of 24 cubic inches. The company has created a box with a width that is 2 inches less
than its length. The height is 5 inches greater than the length. What are the dimensions?
Answers
Answer:
3in by 1in by 8in
Step-by-step explanation:
Volume of the box = Length × Width × Height
Given
Volume = 24in³
If the width is 2inhes less than the length
W = L-2... 2
Also if the height is 5 inches greater than the length, then;
H = L+5 ... 3
Substitite 2 and 3 into the formula.
V= LBH
24 = L(L+5)(L-2)
24 = L(L²+3L-10)
24 = L³+3L²-10L
L³+3L²-10L-24 =0
Factorize
The factored form is
(L+2)(L²+L−12) = 0
L²+L-12 = 0
L²+4L-3L-12 = 0
L(L+4)-3(L+4) = 0
(L+4) = 0 and L-3 = 0
L = 3in
W = L-2
W = 3-2
L = 1in
H = L+5
H=3+5
H = 8in
Hence the dimension is 3in by 1in by 8in

What is the measure of angle x? Explain how you know.
Answers
Answer: x = 30' , y = 45'
hope this helps
Step-by-step explanation:
U is 90' it's a right triangle
well simple VRT you already know 2 angles which is 60' and 90'
R = 60'
V = 90'
T = x
you know that a triangle = 180'
so you do
180 - 60 - 90 = x
30 = x
if you want to do y
then you already know that U is 90' on both sides.
since you also know S,
S = 45'
U = 90'
V = y
180 - 90 - 45 = y
45 = y
