Answer:
1,1/7 or 0.85
Step-by-step explanation:
d-10-2d+7=8+d-10-3d=-5d=-d=d=5
in mathematics there is nothing like 1d,it is d
re-arrange
d-2d-d+3d+5d+d-d=10-7+8-10+5
7d=6
d=6/7
d=1,1/7 or 0.85

What is the value of x? Please provide an explanation, thanks!
Step-by-step explanation:
x + 1 + 2x + 2 + 12x - 18 = 180 (sum angles in triangle)
15x - 15 = 180
15x = 195
x = 13deg
Topic: Angles
If you like to venture further, do check out my insta (learntionary) where I constantly post math tips! Thanks!
Step-by-step explanation:
(x+1)°+(2x+2)°+(12x-18)°=180°
15x+3°-18°=180°
15x+15°=180°
15x=180°-15°
x=165°/15°
x=11° Answer..

Find the value of "x".
Answer:
x = 4.52984
Step-by-step explanation:
Since the triangle has a right angle you need to use the the trigonometric function cos (theta which is the angle given that isn't 90°) = adjacent / hypotenuse (adjacent is the side close to the angle you're using which is 22° and the hypotenuse is the longest side of the triangle that is in the away from the right angle)
From there you plug in the numbers which now become cos (22°) = 4.2 / x
Then you isolate the x by multiplying it to both sides so it's on the left and divide both sides by cos (22°) which will end you up x = 4.2 / cos (22°)
Then you just divide and you 4.52984
An object placed in a graduated cylinder raised the volume from 12.2 mL to 14.5 mL. Find the volume of the object.
Answer:
2.3 mL
Step-by-step explanation:
This is called finding the volume by displacement. By subtracting the final volume and the initial volume you can determine how much the volume changed when the object was added. That change in voulme represents the volume of the object, so in this case:\
14.5-12.2 = 2.3 mL
The change in the volume of the object is, 2.3 mL.
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
We have to given that;
An object placed in a graduated cylinder raised the volume from 12.2 mL to 14.5 mL .
Here, An object placed in a graduated cylinder raised the volume from 12.2 mL to 14.5 mL .
Hence, The change in the volume of the object is,
⇒ 14.5 - 12.2 mL
⇒ 2.3 mL

Find the zeros of the function.
Enter the solutions from least to greatest.
f (x)=(x -3)(2x -8)f(x)=(x−3)(2x−8)
Answer:
The zeroes of the function are: 3 and 4
Step-by-step explanation:
Zeroes of a function are the values on which the function produces zero output. To find the zeroes of a function, the function is put equal zero and the values of the variable are found using the equation. The values of x are the zeroes of the function.
Given function is:
[tex]f(x) = (x-3)(2x-8)[/tex]
Putting the function equal to zero
[tex]f(x) = 0\\(x -3)(2x -8) = 0\\x-3 = 0\\x = 3\\2x-8 = 0\\2x = 8\\\frac{2x}{2} = \frac{8}{2}\\x = 4[/tex]
We get two values for x, x=3 and x=4
Hence,
The zeroes of the function are: 3 and 4

Question: (help please?!?!)Bridget has $2,835 in her savings account. Each pay period, $945 is deposited into
her savings account. If her paycheck deposits are the only transactions, which of the
following equations could be used to find y, the amount in her savings account based
on x, the number of times she is paid?
A y = 2,835 - 945x
B 2,835y = 945x
C y = 945x + 2,835
D y = 2,835x + 945
Answer:
C. y = 945x + 2,835
Step-by-step explanation:
Each pay period 945 dollars is deposited so that's the slope, which x stands for each pay period. She already started with 2,835 in her savings account so that is the y-intercept.
Slope: 945x
Y- intercept: 2,835
Therefore,
equation: y = 945x + 2,835
