Answer:
X = -7/2
Step-by-step explanation:
Answer:
x = -7/2
Step-by-step explanation:
-(7-2x)+7=-7
-7 -7
Start by subtracting -7 from both sides.
-(7-2x) = -14
Divide both sides by -1 to eliminate the negatives.
-(7-2x) = -14
--------- -------
-1 -1
Simplify.
7-2x = 14
Subtract -7 from both sides.
-2x = -7
Divide both sides by -2
-2x = -7
----- ----
-2 -2
x= -7/2
Check if -7/2 by plugging it back into the equation: (-7/2 = -3.5)
-(7-2(-3.5))+7 = -7

Step-by-step explanation:
Gabriella makes a profit of $.80 for every cup of coffee that she sells at her coffee shop she wanted to make a profit of at least $75 today on coffee if she’s sold 90 cups today which statement is correct
Answer:
Gabriela needs to sell 4 more cups of coffee to make a profit of $75.
She sells 90 cups and makes $0.80 profit on each cup. That equals $72 profit.
90 x $0.80= $72
She wants to make $75 profit.
$75 - $72 = $3 profit short for the day
$3/$0.80 = 3.75 cups of coffee short so to make her profit she must sell a total of 94 cups of coffee for the day or an additional 4 cups.

d) what was manuel's average ernings per hour, including tips? round to the nearest cent
Answer:
a. 90
b. 44.55
C. 134.55
D. 22.42
Step-by-step explanation:
A. 6*15 = 90
B. 15 % of 1188 is 178.2, and 178.2 divided by 4 (0.25%) is 44.55
C 90 + 44.55 = 134.55
d. 134.55 divided by 6 hours worked is 22.42
a. The earning should be 90.
b. The money that should be made is 44.55.
c. The total salary for the day is 134.55
d. The Manuel average earnings per hour, including tips is 22.42
Calculation of the earning, money, total salry, and average earnings per hour:a.
The earnings should be
= 6(15)
= 90
b. The money made should be
The 15% of 1188 should be 178.2
Now we have to divide the 178.3 from 4 so it comes 44.55.
c. The total salary should be
= 90 + 44.55
= 134.55
d. The average earnings per hour should be

Fried chicken- 24 pieces
Deli meats- 3 2/3
Lasagna 10 3/4
Answer:
25 guests is 2.5 times more than 10

Multiply by 2.5
Chicken = 16 x 2.5 = 40
Lasagna = 7 x 2.5 = 17.5 , round to 18
Deli meat = 1.8 x 2.5 = 4.5, round to 5

Solve the equation.
b + 6 = 27
Answer:
Step-by-step explanation:
b+6=27
b=27-6
b=21
Answer:
b = 21
Step-by-step explanation:
To find this answer, all you have to do is subtract 6 from both sides of the equal sign, where you will cancel out the 6 and subtract 6 from 27. 27 minus 6 is 21, so you are left with b = 21

All sale items are marked an additional 10% off the sale price. If a coat that originally costs $110 is on sale for 25% off, what is the new sale price? Is this a reduction of 35% off the original price
Answer:
The new sales price is $74.25
Step-by-step explanation:
110 x 0.25 = 27.5
110 - 27.5 = 82.5
82.5 x 0.10 = 8.25
82.5 - 8.25 = 74.25
Simply discounting 35% off the original price does not work in this specific problem.
a can of paint covers 400 square feet how many cans will needed to cover 3,000 square feet
Answer:
7 and a half cans of Paint ( 7.5 cans of paint )Step-by-step explanation:
If one can of paint covers 400 square feet then this should be easy. Since you need 3,000 square feet covered with paint (and one paint can cover 400 sq) then just divide 3,000 by 400.
This will show you how many times 400 can go into 3,000 which is the same as saying "how many cans of paint can i used to cover 3,000 square feet?"

Predict how many times Max will choose a rectangular cracker if he carries out this process 200 times
Answer:
70 times.
Step-by-step explanation:
The following data were obtained from the question:
SHAPE >>>>>>>>>>>>> FREQUENCY
Oval >>>>>>>>>>>>>>> 18
Rectangle >>>>>>>>>> 14
Star >>>>>>>>>>>>>>> 8
TOTAL >>>>>>>>>>>>> 40
next, we shall determine the probability of chosing a rectangular cracker. This is illustrated below:
Event of Rectangle (nR) = 14
Sample space (S) = 40
Probability of chosing rectangle, P(R) =?
P(R) = nR/nS
P(R) = 14/40
P(R) = 7/20
Therefore, the probability of chosing a rectangular cracker is 7/20.
Thus, if the process were carried out 200 times, the probability of chosing a rectangular cracker will be:
= P(R) × 200
P(R) = 7/20
= 7/20 × 200
= 70
Therefore, max will chose a rectangular cracker 70 times.

Answer: Choice C) Upper right corner (aka northeast corner)
====================================================
Explanation:
Rational numbers are ones where we can write as a fraction of two integers. Any rational number is in the form a/b where a,b are integers and b is nonzero.
Terminating decimals can be written as a rational number. Something like 3.1 is equivalent to 31/10.
Of the four answer choices, only choice C is correct.
Choice A has the value '3' as a rational number, but it doesn't have it in the set of integers as well. So that's why choice A is incorrect.
Choice B has -3.4 in the set of integers, which is not correct. Integers do not have any decimal portion. The same applies to choice D also. We can rule choices B and D out.

3|3t+1|=2|6t+3| Need hep
Answer:
your answer would be t=-1 or t=1
Step-by-step explanation:
-(2t-3) = 3t-2
Multiply
-2t+3 = 3t-2
Rearrange and Add up
-5t = -5
Divide both sides by 5
-t = -1
Multiply both sides by (-1)
t = 1
Which is the solution for the Negative Case
Solve the Positive Case
(2t-3) = 3t-2
Rearrange and Add up
-t = 1
Multiply both sides by (-1)
t = -1

Write the equation of the line in point-slope form that passes through the given point with the given slope (1,5); m = -3
Answer:
y - 5 = -3(x-1)
Step-by-step explanation:
We have the slope and a point
Point slope form is
y-y1 = m(x-x1) where m is the slope and ( x1,y1) is a point on the line
y - 5 = -3(x-1)

say you have (-4,-4) and (8,4)
which ones are the y2, y1, x2, and x1
please show work 3[x+4]+4x= -2
Answer:
x = -2
Step-by-step explanation:
First, you eliminate parentheses using the distributive property.
3(x +4) +4x = -2
3x +12 +4x = -2
Then you collect terms.
7x +12 = -2
You can subtract 12 (from both sides).
7x = -14
Finally, divide by the coefficient of the variable.
x = -14/7 = -2
The solution is x = -2.

Comment on the work
When you add, subtract, multiply, divide, or perform any other operation on one side of the equation, you must do the same thing on the other side. That is how the equal sign stays valid. That is why we subtracted 12 from both sides of the equation. It is also why we divided both sides of the equation by 7.
Those steps, subtract 12, divide by 7, are chosen for the purpose of getting the x-term by itself, then getting by itself. In general, when there's an added term you don't want, add its opposite to both sides of the equation. When there's a factor you don't want, divide both sides of the equation by that.
