Answer:
X=-4 last answer i got i hope it is helpful have a nice day
Step-by-step explanation:
Let's solve your equation step-by-step.
6(3x+5)=7(2x+2)
Step 1: Simplify both sides of the equation.
6(3x+5)=7(2x+2)
(6)(3x)+(6)(5)=(7)(2x)+(7)(2)(Distribute)
18x+30=14x+14
Step 2: Subtract 14x from both sides.
18x+30−14x=14x+14−14x
4x+30=14
Step 3: Subtract 30 from both sides.
4x+30−30=14−30
4x=−16
Step 4: Divide both sides by 4.
4x
4
=
−16
4
x=−4
Answer:
x=−4
Answer:
The solution is (-3, -2).
Step-by-step explanation:
Please note that if you simply add these 2 equations together, 9x - 9x = 0, and you are then left with -5y = 10. Thus, y = -2. Subbing -2 for y in the first equation, we get 9x - 8(-2) = -11, or 9x + 16 = -11.
Subtracting 16 from both sides, we get 9x = -27, so that x = -3.
The solution is (-3, -2).
Answer:
7.1 (7.06 rounded to the tenth)
Step-by-step explanation:
The formula for Area of a Circle is: π·r²
R = Radius
π = pi, or 3.14
As long as you know the formula, this is easy!
In class, you may have already been told that the radius is <em>half </em>of the diameter.
1. Half of 3 ft is 1.5 ft.
2. Plug 1.5 in for r, in your calculator
3. Do the calculation, and you should come out to get 7.06858347058
4. Round it!
Finding area for a circle is satisfying, isn't it? xD
Answer:
![\sqrt[4]{x^5}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx%5E5%7D)
Step-by-step explanation:
A fraction exponent converts into a radical. The denominator is the index of the radical (farthest left number) and the numerator is the exponent of the base inside (the farthest right number). The base of the fraction exponent is the base number in green. To write this expression, simply the exponents into one exponent and one base.
Now convert to the radical.
![x^{\frac{5}{4}} = \sqrt[4]{x^5}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B5%7D%7B4%7D%7D%20%3D%20%5Csqrt%5B4%5D%7Bx%5E5%7D)
21 because you just multiply the 2 numbers.
