2c+7k=t-2 solve for c
Answer:
c = (t - 2 + 7t) / 2
Step-by-step explanation:
We can isolate c, getting 2c = t - 2 + 7t.
Then, we can divide both sides by 2, getting c = (t - 2 + 7t) / 2.

Mario has LaTeX: 2\frac{1}{4}2 1 4 pounds of trail mix. He puts equal amounts of the trail mix into 6 bags for a hike with his friends. If he uses all of the trail mix, how many pounds will be in each bag?
Answer:
0.375 poundsStep-by-step explanation:
Let the amount of trail mix in each bag be x pounds. If Mario has [tex]2\frac{1}{4}[/tex] pounds of trail mix and puts equal amounts of the trail mix into 6 bags for a hike with his friends, the amount of trail mix in each bag can be derives using the expression;
[tex]2\frac{1}{4} = 6 * x[/tex]
solving for x
[tex]\dfrac{9}{4} = 6x\\\\2.25 = 6x\\\\divide\ both \ sides \ by \ 6\\\\\dfrac{2.25}{6} = \dfrac{6x}{6} \\\\x = 0.375\\[/tex]
Hence 0.375 pounds of trail mix will be in each bag
Violet was carrying around the steps to solve square root of 3x plus 1 = 4. On her way through the Math Factory, Violet dropped them and they mixed with other steps. Put the correct steps in order to solve square root of 3x plus 1 = 4.
Answer:
First, square both sides (d.) leaving 3x + 1 = 16
Second, subtract 1 from both sides (a.) leaving 3x = 15
Third, divide by 3 from both sides (e.) leaving x = 5

A camping ground began with 240 pounds of food and each day consumed about 12 pounds. After how many days did they have 180 pounds left
Answer:
5 days
Step-by-step explanation:
Set up linear equation; food= 240-12(day) f=240-12d
f(1)=240-12(1)=240-12=228
f(2)=240-12(2)=240-24=216
Now set food to equal 180, solve for days:
180=240-12d
-240 -240
-60=-12d
/-12 /-12
5=d
To check: f(5)=240-12(5)=240-60=180

Answer:
Step-by-step explanation:
Bob's deal : 11/10= 1.1 dollars per bagel
Danny's bagel=3/4=0.75 dollars per bagel
Danny's deal is better the price is lower
2- fraction : 11/10>3/4
1.1>0.75 the lower the price the better
3- Danny's deal is better because the price of 10 bagels=7.5 dollars
At a sale, dresses were sold for 95% of their original price. If the dresses originally cost $200 each, how much did a dress cost on sale?
Turn the percentage into a decimal.
95% / 100 = 0.95
Multiply.
200 * 0.95 = 190
Subtract.
200 - 190 = $10
Therefore, the dress costs $10 on sale.
Best of Luck!
Answer: The answer is 190.

Answer:
12 only.
Step-by-step explanation:
When the question is asking for f(0), it is asking for the value of y when x = 0.
We see that there is only 1 intersection at x = 0, and the y value would equal 12.
Therefore, our answer is 12 only.
Answer:
The answer is a.12 only its where the x coordinate stays 0 and the y coordinate decreases or increases
Step-by-step explanation:
Simpify the expression. -2(y + 3) -7y
Mary and Jane have $48 to share in the ratio 3:5. How much did each girl 2 points
receive? (SHOW WORKING)
Answer:
Mary- $18
Jane- $30
Step-by-step explanation:
Add the numbers in the ratio together to get 8, and multiply 8 by the variable of x. Divide the total amount of money that both girls earned by 8. You will get x=6. Multiply 6 by 3 to get the amount of money Mary earned, which is 18, and multiply 6 by 5 to get the amount of money Jane earned, which is 30.
x(3+5) = $48
3x + 5x = $48
8x = $48
8x/8 = $48/8
x = $6
3($6):5($6) = $18:$30
Answer:
Mary = $18
Jane = $30
Step-by-step explanation:
The first thing you need to do is find out how much each part is. To do that you need to add each side of the ratio together (3 + 5 = 8). THen you set up an equation showing the 8 parts * x = 48 and solve for x.
8x = 48
x = 6 <-- Value of each part
Now you multiply the 6 by the number on each side of the ratio,
Mary = 3 * 6 = 18
Jane = 5 * 6 = 30
The above is your answer.

when will i know when to add or when to subract
Answer:
Look below:
Step-by-step explanation:
adding is when u see 6 + 10. the plus sign ( the cross ) means to add. Subtract is using the minus sign: 6 - 10.
Answer:
You will know when to add or subtract because of keywords and symbols.
Step-by-step explanation:
Most addition and subtraction problems have keywords that tell you what operation to use. For example, so keywords that tell you that you have to add are altogether, sum, together, and a few other words. Some examples of subtraction problems are less than, and a bunch of other words.

help please, little confused.....................................
Answer:
3(3) + 0.75(2) = (3 + 0.75)x
Step-by-step explanation:
The cost per pound of the mixture is the total cost divided by the total weight.
3 lb granola at $3 per lb has a cost of 3(3)
0.75 lb of raisins at $2 per lb has a cost of 0.75(2)
The total cost is 3(3) + 0.75(2)
The mixture has an unknown cost per lb, so we call it x.
When you multiply the cost per lb of the mix by the total weight, you get the total cost.
Total weight of mix: 3 + 0.75
Cost per lb of mix: x
Total cost of mix: (3 + 0.75)x
Above, we know the total cost is 3(3) + 0.75(2)
We set these two amounts equal to get our equation.
3(3) + 0.75(2) = (3 + 0.75)x
Answer: 3(3) + 0.75(2) = (3 + 0.75)x

Using technology or other resources, research the average distance that each planet is from the Sun
(in kilometers). Once you have found the distance, create a chart showing each planet's distance
from the Sun. The Sun itself will not receive a label since it is your starting point. For example,
Mercury is located an average of 57,909,000 km from the Sun, so on the chart, Mercury would be
labeled with a distance of 57,909,000. Use the chart below to record your answers:(Add rows if
necessary)
