Answer:
(6/11, 16/11)
Step-by-step explanation:
While it's fairly obvious that you're supposed to "solve this system of equations," it'd be clearer if you were to say so specifically. Also, reduce ambiguity by using parenthes: You meant either (5/3)x or 5/(3x). Which one? I'm assuming it's (5/3)x.
Then our system is:
(5/3)x - 2y = -2
x + y = 2
Let's eliminate y through addition/subtraction. Multiply the 2nd equation through by +2:
(5/3)x - 2y = -2
2x + 2y = 4
------------------------
(11/3)x = 2
Multiplying both sides by 3 eliminates the fractional coefficient:
11x = 6
Then x = 6/11. Now we must solve for y:
-(6/11) + y = 2
Multiplying 2 by 11/11 yields:
-(6/11) + y = 22/11.
This simplifies to y = 16/11
Thus, the solution of this system is
(6/11, 16/11)
8x + 7(2-3x) = -6(2x + 5)
Answer:
x = 44
Step-by-step explanation:
8x + 7(2-3x) = -6(2x + 5)
8x + 14 -21x = -12x - 30
-13x + 14 = -12x - 30
-x + 14 = -30
-x = -44
x = 44
All of the following are equivalent EXCEPT x < 2 x - 2 < 4 2x < -4 x - 2 < -4

What is the value of c?
What is this expression in simplified form? √32 x √24
A. 16√3
B. 64√12
C. √768
D. 32√3
Answer:
16 sqrt(3) x -> A. 16√3
Step-by-step explanation:
Simplify the following:
sqrt(32) sqrt(24) x
Hint: | Simplify radicals.
sqrt(32) = sqrt(2^5) = 2^2 sqrt(2):
2^2 sqrt(2) sqrt(24) x
Hint: | Evaluate 2^2.
2^2 = 4:
4 sqrt(2) sqrt(24) x
Hint: | Simplify radicals.
sqrt(24) = sqrt(2^3×3) = 2 sqrt(2) sqrt(3):
4 sqrt(2)×2 sqrt(2) sqrt(3) x
Hint: | For a>=0, sqrt(a) sqrt(b) = sqrt(a b). Apply this to sqrt(2) sqrt(3).
sqrt(2) sqrt(3) = sqrt(2×3):
4 sqrt(2)×2 sqrt(2×3) x
Hint: | Multiply 2 and 3 together.
2×3 = 6:
4 sqrt(2)×2 sqrt(6) x
Hint: | Multiply 4 and 2 together.
4×2 = 8:
8 sqrt(2) sqrt(6) x
Hint: | For a>=0, sqrt(a) sqrt(b) = sqrt(a b). Apply this to sqrt(2) sqrt(6).
sqrt(2) sqrt(6) = sqrt(2×6):
8 sqrt(2×6) x
Hint: | Multiply 2 and 6 together.
2×6 = 12:
8 sqrt(12) x
Hint: | Simplify radicals.
sqrt(12) = sqrt(2^2×3) = 2 sqrt(3):
8×2 sqrt(3) x
Hint: | Multiply 8 and 2 together.
8×2 = 16:
Answer: 16 sqrt(3) x

Step-by-step explanation:
Use the slope formula: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\frac{-3-12}{-7-(-4)}[/tex] = [tex]\frac{-15}{-3}[/tex] = 5
Lin’s bike travels 100 meters when her wheels rotate 55 times. What is the circumference of her wheels?
____ m
Answer:
the circumference of her wheel is 1.81 mLin’s bike travels 100 meters when her wheels rotate 55 times.
here, n = 55 rotation and D = 100 meter.
Diameter is the distance bike travel
n is the number of times rotation
C is the circumference of the wheel
what is the domain of the graphed function?
Answer:
Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
Step-by-step explanation:
it is expected that 563 quadrillion thermal units of Btu (British thermal units) of energy will be
consumed worldwide in 2015. In 2003, worldwide consumption was 421 quadrillion Btu. What is the
expected rate of change in consumption from 2003 to 2015? (what is rate of change?)
Answer:
the expected rate of change in consumption is 11.83
Step-by-step explanation:
The computation of the expected rate of change in consumption is shown below:
= (Expected quadrillion thermal units - 2003 quadrillion thermal units) ÷ (difference in years)
= (563 - 421) ÷ (2015 - 2003)
= 142 ÷ 12
= 11.83
hence, the expected rate of change in consumption is 11.83
We simply applied the above formula so that the correct value could come

3x - 7 = 29
What is x
Answer:
x = 12
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
3x - 7 = 29
Step 2: Solve for x
Add 7 on both sides: 3x = 36Divide 3 on both sides: x = 12Step 3: Check
Plug in x to verify it's a solution.
Substitute: 3(12) - 7 = 29Multiply: 36 - 7 = 29Subtract: 29 = 29Here we see that 29 does indeed equal 29.
∴ x = 12 is a solution of the equation.
