Answer:
x=2
Step-by-step explanation:
4(x-1)=2(6-2x)
4x-4=12-4x
Add 4 to both sides
4x=16-4x
Add 4x to both sides
8x=16
Divide by 8 on both sides

the temperature in degrees Celsius?
Use the formula C = (F – 32), where
C represents degrees Celsius and F
represents degrees Fahrenheit.
Answers
Answer:
Boiling point of jet fuel = 165 degrees Celsius
Step-by-step explanation:
Given:
Boiling point of jet fuel = 329°F
Find:
Boiling point of jet fuel in degrees Celsius
Computation:
C = [5/9][F – 32]
C = [5/9][329 – 32]

30x + 7y = 1050.....when x = 28
30(28) + 7y = 1050
840 + 7y = 1050
7y = 1050 - 840
7y = 210
y = 210/7

It costs $3.75 for 25 oz. of candy or $6.30 for 90 oz. of candy. Which is
a better buy?*
O 25 oz.
O 90 oz.
Answers
Answer:
90 OZ.
Step-by-step explanation:
You have to divide the ounces by the price to see how much $1 per ounce costs.
25 divided by 3.75 = 6.6 Ounces for $1
90 divided by 6.30 = 14.28 ounces for $1

Answers
Answer:
To obtain a solution of 12 ml of 8% alcohol, 3 ml of 32% alcohol and 9 ml of water should be used.
Step-by-step explanation:
To determine the amount of 32% alcohol and pure water needed to make a 12 ml 8% alcohol solution, the following calculation is necessary:
If in 12 ml it is sought that 8% of the solution is alcohol, this percentage implies a presence of 0.96 ml of alcohol in the solution.
Now, 12 ml of 32% alcohol has 3.84 ml of alcohol in it, which must be lowered with water to access that amount.
Therefore, since 32/8 is equal to 4, a quarter of the solution composed of 32% alcohol must be placed, while the remaining three-quarters must be pure water.
In conclusion, to obtain a solution of 12 ml of 8% alcohol, 3 ml of 32% alcohol and 9 ml of water should be used.
Consider this right triangle. R 9 55° Q P Enter the length of RQ, to the nearest tenth.
Answers
Answer:
RQ = 7.4
Step-by-step explanation:
From the right triangle PQR,
m∠Q = 90°
m∠P = 55°
Hypotenuse PR = 9
By applying sine rule in the given triangle,
Sin(55°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
0.819152 = [tex]\frac{\text{RQ}}{\text{PR}}[/tex]
0.819152 = [tex]\frac{RQ}{9}[/tex]

D: y − 3 = −3/2(x − 4)
Answers
Answer:
B. [tex] y - 3 = \frac{2}{3}(x - 4) [/tex]
Step-by-step explanation:
We can create an equation to represent the graph in point-slope form, given as [tex] y - y_1 = m(x - x_1) [/tex], by using a point (x1, y1) on the line, (4, 3) and the slope (m) of the line.
Let's find slope using the two points (4, 3) and (-2, -1).
[tex] slope (m) = \frac{y_2 - y_1}{x_2 -x_1} = \frac{-1 - 3}{-2 - 4} = \frac{-4}{-6} = \frac{2}{3} [/tex]
Substitute m = ⅔, x1 = 4, and y1 = 3 in [tex] y - y_1 = m(x - x_1) [/tex].
The equation that represents the graph would be:
✅[tex] y - 3 = \frac{2}{3}(x - 4) [/tex],

28 - K _> 7(K - 4)
Answers
Answer:
Solving the inequality [tex]28-K\geq 7(K-4)[/tex], we get [tex]\mathbf{K\leq 7}[/tex]
Step-by-step explanation:
We need to solve the inequality [tex]28-K\geq 7(K-4)[/tex]
Using the BODMAS rule, first we will solve the bracket:
[tex]28-K\geq 7(K-4)\\28-K\geq 7K-28[/tex]
Now, we will subtract 28 from both sides
[tex]28-K-28\geq 7K-28-28\\-K\geq 7K-56[/tex]
Subtracting -7k on both sides
[tex]-K-7K\geq 7K-56-7K\\-8k\geq -56[/tex]
Finally, divide both sides by -8 and inverse the inequality, as we are dividing with a minus digit.
[tex]\frac{-8K}{-8}\leq \frac{-56}{-8}\\K\leq 7[/tex]
So, solving the inequality [tex]28-K\geq 7(K-4)[/tex] we get [tex]\mathbf{K\leq 7}[/tex]

Answer:
1/3.
Step-by-step explanation
1/12 * 24 = 2 players suspended leaving 22 players.

Hey there! Let's answer each part of this question in order.
Part aIf Pedro withdrew [tex]\$35[/tex] per week, his change in balance could be represented as [tex]-35x[/tex] since [tex]x[/tex] is the number of weeks. Add this to his initial balance of [tex]\$710[/tex] to get the first answer:
[tex]\huge\boxed{710-35x}[/tex]
Part bThe same concepts can be applied to solve the next part. Maria started off with [tex]\$570[/tex] in her account and withdrew [tex]\$25[/tex] each week. Apply the same process from the first part to get the second answer:
[tex]\huge\boxed{570-25x}[/tex]
Part cWrite an equationFor the last part, we need to find the value of [tex]x[/tex] that makes the expressions we made in the first two parts equal to each other, so start by making them into an equation.
[tex]\huge\boxed{710-35x=570-25x}[/tex]
Solve the equationNow we need to solve this equation. Start by bringing the constants to the right and the variables to the left.
Keep in mind that when you move a term to the other side of the equation, you need to change its sign, as you are adding or subtracting the same number from both sides of the equation.
[tex]\begin{aligned}710-35x&=570-25x\\-35x&=570-25x-710\\-35x+25x&=570-710\end{aligned}[/tex]
Now, combine the like terms with addition and subtraction.
[tex]\begin{aligned}-35x+25x&=570-710\\-10x&=-140\end{aligned}[/tex]
Finally, divide both sides of the equation by [tex]-10[/tex] to fully isolate the variable and find the final answer.
[tex]\begin{aligned}-10x&=-140\\x&=14\ \text{(weeks)}\end{aligned}[/tex]
[tex]\huge\boxed{14\ \text{weeks}}[/tex]
Check your answerWe can also check our answer by substituting the final answer back into each expression, simplifying, and making sure the answers are equal.
[tex]\begin{array}{l|l}710-35x&570-25x\\710-35*14&570-25*14\\710-490&570-350\\220&220\end{array}[/tex]
Since the expressions are equivalent, we know that Pedro's balance is the same as Maria's balance after [tex]14[/tex] weeks.
