How many solutions are there to the following equation?
5 ( x-3 ) - 3x = 8x - 15 - 6x
A) exactly two solutions
B) exactly one solution
C) no solution
D) infinitely many solutions
Answer:
D) infinitely many solutions
Step-by-step explanation:
5 ( x-3 ) - 3x = 8x - 15 - 6x
5x - 3x - 15 = 8x - 6x - 15
2x - 15 = 2x - 15
2x = 2x
Since, equations of both lines are same. Therefore, there are infinitely many solutions.
Answer:
D
Step-by-step explanation:
Given
5(x - 3) - 3x = 8x - 15 - 6x
5x - 15 - 3x = 2x - 15
2x - 15 = 2x - 15
Since both sides are the same then any real value of x will be a solution.
That is there are infinitely many solutions

Wilson is 6 years older than Mary. Wilson's age is 10 years less than five times Mary's age. The equations below model the relationship between Wilson's age (w) and Mary's age (m):
w = m + 6
w = 5m − 10
Which is a possible correct method to find Wilson's and Mary's ages?
Solve w + 6 = 5w − 10 to find the value of w.
Write the points where the graphs of the equations intersect the x axis.
Solve m + 6 = 5m − 10 to find the value of m.
Write the points where the graphs of the equations intersect the y axis.
Answer:
no 4=f
Step-by-step explanation:
dwfn sdv and it appers to be marys age ;)
think before you do something rude
Answer:
C. Solve m + 6 = 5m - 10
Step-by-step explanation:
Wilson is 6 years older than Mary.
(MARY's age + 6 = WILSON's age)
Wilson's age is 10 years less than five times Mary's age.
(MARY's age * 5 - 10years = WILSON's age)
(Mary is 4 years old and Wilson is 10:
4 + 6 = 10
4(5) = 20 - 10 = 10
just in case you were curious)
Good luck!!

A jar contains 21 marbles: 8 white, 3 green, and 10 red. Write the described ratio in simplest form.
A. number of white marbles to number of green marbles.
Answer:
The question you posted was a bit confusing for me, but I'm assuming that you want the simplified ratio of the number of white marbles to the number of green marbles.
The answer would be 8:3.
Step-by-step explanation:
There are 8 white marbles and 3 green marbles, so you get 8:3. And since 8 and 3 are relatively prime, no simplifying is needed.
The answer is 8:3.
use the quotient rule to find the derrivatives of 3/x^2
Answer:
f'(x) = -6/x³
Step-by-step explanation:
We are given;
f(x) = 3/x²
Using quotient rule, we can write as;
f(x) = g(x)/h(x)
To find the derivative, from quotient rule, we can write;
f'(x) = [(h(x)*g'(x)) - (g(x)*h'(x))]/(h(x))²
g'(x) = 0
h'(x) = 2x
Thus;
f'(x) = [(x²*0) - (3*2x)]/(x²)²
f'(x) = -6x/x⁴ = -6/x³
f'(x) = -6/x³

Here is a set of signed numbers: 7, -3, LaTeX: \frac{1}{2}1 2, -0.8, 0.8, LaTeX: -\frac{1}{10}− 1 10, -2 Order the numbers from least to greatest. Group of answer choices 7, 0.8, 1/2, -1/10, -0.8, -2, -3 -3, -2, -0.8, -1/10, 1/2, 0.8, 7 -1/10, 1/2, -0.8, 0.8, -2, -3, 7
Answer:
[tex]-3, -2, -0.8, -\frac{1}{10} ,\frac{1}{2}, 0.8, 7[/tex]
Step-by-step explanation:
Given
[tex]7, -3, \frac{1}{2}, -0.8, 0.8, -\frac{1}{10}, -2[/tex]
Required
Order from least to greatest
[tex]7, -3, \frac{1}{2}, -0.8, 0.8, -\frac{1}{10}, -2[/tex]
Convert 1/2 and -1/10 to decimals
[tex]7, -3, 0.5, -0.8, 0.8, -0.1, -2[/tex]
Negative numbers are always the least of all numbers.
In the given list, the negative numbers are:
[tex]-3, -0.8, -0.1, -2[/tex]
The higher the magnitude of a negative number, the smaller it is.
--------------------------------------------------------------------------------------------
Take for instance: -7 and -8.
-8 has a magnitude of 8 and -7 has a magnitude of 7.
Because 8 > 7 (the magnitudes), then
-8 < -7
--------------------------------------------------------------------------------------------
Using the above analysis:
[tex]-3, -0.8, -0.1, -2[/tex] from least to greatest is:
[tex]-3, -2, -0.8, -0.1[/tex]
Considering the positive numbers:
[tex]7, 0.5, 0.8[/tex]
From least to greatest, it is:
[tex]0.5, 0.8, 7[/tex]
Merge the negative and the positive numbers:
[tex]-3, -2, -0.8, -0.1,0.5, 0.8, 7[/tex]
Convert 0.5 and -0.1 back to fractions
[tex]-3, -2, -0.8, -\frac{1}{10} ,\frac{1}{2}, 0.8, 7[/tex]

So what the answer for “Kelly has $5.38 in her account before receiving her $832.19 paycheck. She writes checks for rent and car insurance in the amounts of $359.82 and $72.38. She also withdraws $30. What is her current balance?” ? Please I need this answer right away please
Answer: $375.37
Step-by-step explanation:
From the question, we are told that Kelly has $5.38 in her account before receiving her $832.19 paycheck. We are further told that she writes checks for rent and car insurance in the amounts of $359.82 and $72.38 and that she also withdraws $30.
Her current balance will be:
= $5.38 + $832.19 - $359.82 - $72.38 - $30
= $375.37
Her current balance is $375.37

4.2/-0.2
Answer:
yes cuz +1+1
Step-by-step explanation:
Answer:
21
Step-by-step explanation:
Plzzz helppppp !!!!! Write this as an equation that represents the function
Step-by-step explanation:
y = mx + c
When x = 0, y = 2.
=> (2) = m(0) + c, c = 2.
When x = 3, y = 8.
=> (8) = m(3) + 2, 3m = 6, m = 2.
Hence the answer is y = 2x + 2.
3 balloon + 2 cakes = £19
9 balloon + 3 cakes = £42
work out:
1 balloon in £
1 cake in £
Step-by-step explanation:
3 balloons + 2 cakes = £19
=> 9 balloons + 6 cakes = £57 (multiply by 3)
9 balloons + 6 cakes = £57
- (9 balloons + 3 cakes = £42)
=> 3 cakes = £15, 1 cake = £5.
Therefore 3 balloons + 2(£5) = £19,
3 balloons = £9, 1 balloon = £3.
Hence each balloon is £3 and each cake is £5.

She earns $7.50 every hour that she dusts.
She earns $10.00 every hour that she scrubs floors.
She scrubbed floors for 1 1/2 hours and dusted for hours.
How much money did Mel earn?
Answer: $45
Step-by-step explanation: 10 for the hour she scrubbed the floor half of that which is 5 for the half hour she scrubbed so that would be $15, then 7.50 times 4 for the hours she dusted which would be 30, and 30 plus 15 is 45

The hanger image below represents a balanced equation,
6
21
Find the value of d that makes the equation true.
MY
d=
Answer:
The value of d that balances the equation is d=15
Step-by-step explanation:
Equations
We are given an image with a hanger that represents a balanced equation.
If the equation is balanced, then the 'weights' of each side should be equal.
On the right side, there is 21 and on the left side, there are 6 and d.
Adding both, we have 6+d on the left side.
Equating both sides:
6 + d = 21
To find d, we subtract 6 on both sides:
d = 21 - 6
d = 15
The value of d that balances the equation is d=15
Answer:
d=15
Step-by-step explanation:
6+d=21
so that means d=15
6+15=21

A scuba diver descends below the surface of a lake at a rate of 12 feet per minute. What integer represents the depth of the diver after 4 minutes?
Since this scuba diver descends below the surface of a lake at a rate of 12 feet per minute, an integer which represents the depth of the diver after four (4) minutes is 48 feet.
What is the rate of change?The rate of change can be defined as a type of function that describes the average rate at which a quantity decreases or increases with respect to another quantity.
Mathematically, the rate of change for the depth covered by this scuba can be calculated by using this formula;
Rate of change = Depth/time
Making depth the subject of formula, we have:
Depth = Rate of change × time
Substituting the given parameters into the formula, we have;
Depth = 12 × 4
Depth = 48 feet.

What is the slope of the linear equation y=x+10
a. Slope=m=10
b. Slope=m=1
c. Slope=m=5
d. Slope=m=11
Answer:
slope = 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x + 10 ← is in slope- intercept form
with slope m = 1
