Distribute;
5w - 15 < 5w + 20
Subtract 5w from both sides;
-15 < 20
Answer:
w<5
Step-by-step explanation:
(5*w-3*5)<5w+20
5w-15<5w+20
5w-5w<20-15

The ratio of the number of red pens to the number of black pens in simplest form is, 1 : 3.
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
We have to given that;
There are 28 red pens and 84 black pens in a bag.
Here, Number of red pens = 28
And, Number of black pens = 84
Hence, The ratio of the number of red pens to the number of black pens is,
⇒ Number of red pens : Number of black pens
⇒ 28 : 84
⇒ 28/84
⇒ 14 / 42
⇒ 1 / 3

A chemical company makes up batches of copper sulfate solution by adding 250 kg of copper sulfate powder to 1000 liters of water. A laboratory chemist wants to make a solution of identical concentration, but only needs 350 mL (0.35 liters) of solution.
How much copper sulfate powder should the chemist add to the water? Enter your answer in the box below in decimal format.
The mass of copper sulfate that the chemist should add is______
kg.
help me please
Answer:
0.07 kgStep-by-step explanation:
Assuming copper sulfate has same density as waterChemical to water ratio as per given is:
250 kg : 1000 liter = 1 kg : 4 literLab solution is 350 ml
Converting to same ratio as above:
350/(1 + 4) = 70 ml
70 ml : 280 ml = 70 g : 180 ml = 0.07 kg : 180 mlAnswer is 0.07 kg
Solve the following inequality for g. Write your answer in simplest form.
-5-3(5g-4)≥2g+6-10
Answer:
[tex]g\leq \frac{11}{17}[/tex]
Step-by-step explanation:
[tex]-5-3(5g-4)\geq 2g+6-10\\-5+(-15g+12)\geq 2g-4\\-5+(-15g)+12\geq 2g-4\\7-15g\geq 2g-4\\7\geq 17g-4\\3\geq 17g\\\frac{11}{17} \geq g\\g\leq \frac{11}{17}[/tex]
The value of g in the given inequality -5-3(5g-4) ≥ 2g+6-10 is equal to or less than 11/17, g ≤ 11 / 17
What is an inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given is an inequality -5-3(5g-4) ≥ 2g+6-10
Solving for g,
-5-3(5g-4) ≥ 2g+6-10
-5-15g+12 ≥ 2g+6-10
-15g+7 ≥ 2g-4
7 ≥ 17g -4
11 ≥ 17g
11 / 17 ≥ g
g ≤ 11 / 17
Hence, the value of g is equal to or less than 11/17, g ≤ 11 / 17

Which of the equations below can be solved by square roots? How would you solve the other equation? Explain your reasoning. Give the solutions to both equations. Equation A: x? - 9x = 0 Equation B : x2-9=0
Answer:
Equation A is factoring, x=9 and x=0
Equation B is the square root, x=3
The equation A: x² - 9 = 0 can be solved by square root method
The equation B: x² - 9x = 0 can only be solved by factoring
The given equations are:
Equation A: x² - 9x = 0
Equation B: x² - 9 = 0
The equation x² - 9 can be rewritten as:
x² - 3² = 0
This is a difference of two squares which can be further expressed as:
(x - 3)(x + 3) = 0
x - 3 = 0
x = 3
x + 3 = 0
x = -3
This shows that the equation x² - 9 = 0 has two roots x = -3 and x = 3
Also, from x² - 9 = 0
[tex]x = \pm\sqrt{9} \\\\x = \pm3[/tex]
For the equation x² - 9x = 0
This can be factored as x(x - 9) = 0
x = 0, x = 9
This is not solved by the square root method.
Therefore, the equation x² - 9 = 0 can be solved by square root method

If f(1)=7f(1)=7 and f(n)=f(n-1)+2f(n)=f(n−1)+2 then find the value of f(4)f(4).
Answer:
Step-by-step explanation: f1 =7
f2 = 5(7) + 2 = 37
f3 = 5(37) + 2 = 27
f4 = 5(9) + 2 = 47____
The value of f(4)f(4) f(1) = 7f(1) = 7 and f(n) = f(n-1) + 2f(n) = f(n−1) + 2 is,
121.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, f(1) = 7f(1) = 7 and f(n) = f(n-1) + 2f(n) = f(n−1) + 2.
By this pattern,
f(4)f(4) = [f(4 - 1) + 2f(4)][f(4 - 1) + 2f(4)].
f(4)f(4) = [f(3) + 2f(4)][f(3) + 2f(4)].
f(4)f(4) = [f(3) + 2(4)][f(3) + 2(4)].
f(4)f(4) = [3 + 8][3 + 8].
f(4)f(4) = [11][11].
f(4)f(4) = 121.

Step-by-step explanation:
(2, 10) and (4, 10) have the same y value so it's not a function etc. etc.
Answer:
D. The relation represents y as a function of x, because each value of x is associated with a single value of y
Step-by-step explanation:
As long as no one x-value has two solutions, it can be considered a function. The x-values are {0, 2, 4, 6, 8}. Since there isn't any repetition, this can be considered as a function. The fact that 10 is repeated in the y-values doesn't affect that it is a function.
