Answer:
[tex]x=\frac{324}{5}[/tex]
Step-by-step explanation:
Given the following question:
[tex]\sqrt{5x} -7-3=8[/tex]
To find the answer we are going to use inverse of operations to isolate the variable x, doing this we can then find the value of the variable and then have our answer.
[tex]\sqrt{5x} -7-3=8[/tex]
[tex]-7-3=-10[/tex]
[tex]\sqrt{5x} -10=8[/tex]
[tex]-10+10=0[/tex]
[tex]8+10=18[/tex]
[tex]\sqrt{5x} =18[/tex]
[tex]\sqrt{5x} =5[/tex]
[tex]18\times18=324[/tex]
[tex]5x=324[/tex]
[tex]5x\div5=x[/tex]
[tex]324\div5=x=\frac{324}{5}[/tex]
[tex]x=\frac{324}{5}[/tex]
Your answer is "x = 324/5."
Hope this helps.
What is (x+4)(3x+7)/(x+4)(x+2) simplified?
Answer:
[tex]\frac{3x+7}{x+2}[/tex]
Step-by-step explanation:
Given the following question:
[tex]\frac{(x+4)(3x+7)}{(x+4)(x+2) }[/tex]
In order to simplify the expression given we can only cancel the common factor which is four.
[tex]\frac{(x+4)(3x+7)}{(x+4)(x+2) }[/tex]
[tex]cf=(x+4)[/tex]
[tex]\frac{x+4}{x+4}[/tex]
[tex]=\frac{3x+7}{x+2}[/tex]
Cannot be simplified further due to it not having any more common factors. Your answer is "3x + 7 / x + 2."
Hope this helps.
Answer:
( 3x+7 ) / ( x+2 )
Step-by-step explanation:
\frac{(x+4)(3x+7)}{(x+4)(x+2)}
When you set up the equation like a fraction, you can now cancel out like terms. (x+4) is in the denominator- as well as the numerator. They are the same in parentheses. So you can cancel. Once that's done, you'll be left with
\frac{3x+7}{x+2}
You cant simplify any further because there are no more (like groups) aka (common factors)
( 3x+7 ) / ( x+2 )

A curve has equation y = x
3 − 4x
2 + 2x
Find the x coordinate of each of the points on the curve at which the gradient of the tangent to the
curve is 2
Answer:
The derivative (or gradient function) describes the gradient of a curve at any point on the curve. Similarly, it also describes the gradient of a tangent to a curve at any point on the curve.
To determine the equation of a tangent to a curve:
Find the derivative using the rules of differentiation.
Substitute the \(x\)-coordinate of the given point into the derivative to calculate the gradient of the tangent.
Substitute the gradient of the tangent and the coordinates of the given point into an appropriate form of the straight line equation.
Make \(y\) the subject of the formula.
The normal to a curve is the line perpendicular to the tangent to the curve at a given point

The area of a rectangle is 75 square feet, and the length is 25 feet. What is the perimeter?
Answer:
56 feet
Step-by-step explanation:
75/25=3 feet
this is another side.
(3+25)x2+56 feets
Answer:
75ft.
Step-by-step explanation:
What you do is subtract two 25s from the area (because there are two sides for length) which gives you 25. The width would be half of that which is 12.5. Then add two widths (12.5+12.5=25), and add that to two lengths (25+25=50). The answer is 75ft as well. Please tell me if I'm wrong.

Answer:
c=30
Step-by-step explanation:
Inverse: 22 + 8 = 30
c = 30
Answer:
c = 30
Step-by-step explanation:
Step 1: Add 8 to both sides.
[tex]c-8+8=22+8[/tex] [tex]c=30[/tex]Step 2: Check if solution is correct.
[tex]30-8=22[/tex] [tex]22=22[/tex]Therefore, the answer is c = 30.

Answer:
The answer is 6
Step-by-step explanation:
2.3... where the 3s go on forever is the same as 2 + 1/3 or 2 & 1/3
The whole number portions add to 3+2 = 5, and we add on the carry of 1 to get 5+1 = 6
3 & 2/3 = 3 + 2/3 = 3 + 0.667 = 3.667 approximately
adding this onto 2.333 leads to
3.667 + 2.333 = 6
Technically the 6's go on forever in the decimal form of 3 & 2/3, but rounding wont have an effect on the answer when we add

The equation 4(x – 3)2 – 5 = 139 has two solutions: one positive and one negative. What is the
negative solution?
7.
Answer:
Step-by-step explanation:
4(x-3)2-5 = 139
(4x-12)-5=139
-20x + 60 = 139
-20x +60 - (60) = 139- 60
-20x = 79 divide both sides by -20
x = -3.95

Answer:
k = 29
Step-by-step explanation:
5k - 3 + 9 + k = 180
6k + 6 = 180
6k = 180 - 6 = 174
k = 174/6 = 29
Evaluate the equation.
12.8 + c = 30.12
A. c =17.28
B. c =17.32
C. c =42.92
D. c =43.02
Answer: B. c = 17.32
Step-by-step explanation:
12.8 + c = 30.12
c = 17.32 [Subtract 12.8 from both sides.]
Therefore, answer is B.

Step-by-step explanation:
you slow -_-
Answer : 5 x 4 (Option C)
Step-by-step explanation : 5 + 5 + 5 + 5 = 20
By trial & error method, we get
5 x 2 = 10 ≠ 20
5 x 4 = 20
5 x 5 = 25 ≠ 20
5 x 10 = 50 ≠ 20
Hence 5 x 4 is the right answer
You can either follow the trial & error method or the following method !!
5 + 5 + 5 + 5 has ' 4 ' fives
Hence, 5 + 5 + 5 + 5 = 5 (since it is the no) x 4 (since it is the no of times 5 is repeating)
Hence 5 x 4 is the right answer

Dang. Ask ur classmates
what is the approximate height of the rice container if the radius is 2.5 in. and the volume is 235.5 in cubed
Answer:
12 in
Step-by-step explanation:
r = 2.5 in
V = 235.5 in³
Find h
Use V = πr²h
so 235.5 = 3.14 * 2.5² * h
235.5 = 19.625 h
h = 235.5/19.625 = 12 in
the difference of a number and ten is at least 91
Answer:
x-10 [tex]\geq[/tex] 91
Step-by-step explanation:
Difference means subtraction, and "a number" since not specified is x, and at least means greater than or equal to and not less than. So the difference (subtract) of a number (x) and 10 is at least (greater than or equal to) 91 :D
Which ordered pairs are solutions to the equation 3x - 2y = 12 ? (hint: plug in the x and y values into the equation to see if it makes a true statement.) Group of answer choices (1,-4.5) (5,-1.5) (2,-3) (0,6) (-2,3) (-2,-9)
Answer:
1,-4.5
Step-by-step explanation:
Answer:
(-2,-9) is the answer
3x - 2y = 12
3(-2) - 2(-9) = 12
-6+18 = 12
12 = 12
