What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The temperature at the time of bed.
Initial temperature = 36° F
The temperature when she woke up.
Final temperature = -9° F
The change in temperature.
= Final temperature - Initial temperature
= -9 - 36
= 45°F
This means that there was a change of 45°F from the time when she went to bed till the time she woke up.
Thus,
The change in temperature is -45°F

find the perimeter of the square on the centimeter grid
Without solving, NO SOLUTION describes which equation?
A) 6a = 9a
B) 5x = 28
C) y = y + 1
D) y + 5 = 12
Answer:
The equation 'y = y + 1' represents NO SOLUTION.
Hence, option 'C' is true.
Step-by-step explanation:
a)
6a = 9a
subtract 9a from both sides
6a - 9a = 9a - 9a
-3a = 0
divide both sides by -3
-3a / -3 = 0/-3
Simplify
a = 0
b)
5x = 28
divide both sides by 5
5x/5 = 28/5
x = 28/5
c)
y = y + 1
subtract y from both sides
y - y = y+1-y
0 = 1
These sides are not equal, so
NO SOLUTION!
d)
y + 5 = 12
subtract 5 from both sides
y + 5 - 5 = 12 - 5
y = 7
Conclusion:
Therefore, the equation 'y = y + 1' represents NO SOLUTION.
Hence, option 'C' is true.
Answer:
1: y=y+1
2: 6a = 9a
Step-by-step explanation:
Without solving, NO SOLUTION describes which equation?
Answer: y=y+1
For which equation is zero a reasonable solution?
Answer: 6a = 9a

What is the exact value of cos(11pi/12)
9514 1404 393
Answer:
[tex]\text{(a)} \quad -\dfrac{\sqrt{2+ \sqrt{3}}}{2}[/tex]
Step-by-step explanation:
The angle is near π, so the cosine value is a negative value near -1. This means the value under the numerator radical must be slightly less than 4. The only answer choice that makes any sense is the first choice.
The value of the cosine is ...
cos(11π/12) ≈ -0.9659
The values of the answer choices are ...
a) -0.9659 . . . . matches the required value
b) -0.2588
c) 0.2588
d) 0.9659
_____
You could use half-angle or angle sum formulas to figure this exactly, but it is much easier to make a multiple-choice selection based on your general knowledge of the cosine function and √3 (≈1.73).

what is x in rx+h=sx-k
Answer:
-k-h/r-s
When solving the goal is to get x on one side and not x on the other.
rx + h = sx - k
rx - sx + h = -k <------- subtract sx from both sides
rx - sx = -k - h <-------subtract h from both sides
x (r - s) = -k -h <------factor out x which is in both rx and sx
x = - k - h / r - s <-------divide by r-s on both sides

family has a square driveway with an area of 210.25 m exponent 2. Find the perimeter of the driveway. Round your answer to the nearest foot. there are approximately 3.3 ft in 1 meter.
Answer:
191 ft.
Step-by-step explanation:
From the question given above, the following data were obtained:
Area (A) of square = 210.25 m²
Perimeter (P) =?
Next, we shall determine the length of each side of the drive way. This can be obtained as follow:
Area (A) of square = 210.25 m²
Length (L) =?
Area of a square is given by:
A = L²
210.25 = L²
Take the square root of both side
L = √210.25
L = 14.5 m
Thus, the length of each side of the drive way 14.5 m
Next, we shall determine the perimeter of the drive way. This can be obtained as follow:
Length (L) = 14.5 m
Perimeter (P) of square =?
Perimeter of a square is given by:
P = 4L
P = 4 × 14.5
P = 58 m
Finally, we shall convert 58 m to foot. This can be obtained as follow:
1 m = 3.3 ft
Therefore,
58 m = 58 m × 3.3 ft / 1 m
58 m = 191.4 ft
58 m = 191 ft
Thus, 58 m is equivalent to 191 ft.
Therefore, the perimeter of the drive way is 191 ft.

The volume of a right rectangle prism is found by multiplying the length of the base by the width of the base by the height of the prism. A right rectangular prism has a volume of 50 cubic inches. If the height of the prism is 4 inches, what is the area of the base of the prism?
9514 1404 393
Answer:
12.5 square inches
Step-by-step explanation:
The area of the base can be written as ...
B = LW
Then the volume formula ...
V = LWH
can be written in terms of the base area as ...
V = BH
The base area can be found by dividing by the height:
B = V/H = (50 in³)/(4 in) = 12.5 in²
The area of the base is 12.5 square inches.

Answer:
4/9 = 20/45
Step-by-step explanation:
divided the numerator of the whole fraction by the fraction missing a number
(in this case, 20 ÷ 4 = 5)
since the numerator and denominator have to be divided by the same number to make an equivalent fraction, you would divide 45 by 5 and would get 9

Find the slope of the line whose equation is 17 + 3y = 7x.
17/3
-7/3
7/3
Rewrite the equation for y:
17 + 3y = 7x
Subtract 17 from both sides:
3y = 7x -17
Divide both sides by 3:
y = 7/3x -17/3
The slope is the number in front of x which is 7/3
The slope is 7/3
Answer:
7/3

So, go down -8 units from the origin (0,0).
Now, go down 3 and right 1 units from -8, until you reach the bottom. Do the same thing from -8 but up 3 and left 1 unit.
