so the question is 5x - 7 = 28 What does x equal
Answer:
x=7
Step-by-step explanation:
Answer:
7
My Logic:
If you work backwards to simplify the eqation you can get x
take 5x-7=28 and add 7 to both sides. so now the eqaton looks like this: 5x=35. next you divide 5 into both sides and you will get 7!
Hope this helps!

A 13 3/4 -inch candle burns down in 11 hours. If b represents how much of the candle, in inches, has burned away at any time given in hours, t, write a proportional equation for b in terms of t that matches the context.
Answer:
5t = 4b
Step-by-step explanation:
Here, we want to write a proportional relationship for b in terms of t
From the question, b represent the amount of candle burned away in a given time t hours
From what we have initially, 13 3/4 burnt in 11 hours
So in 1 hour, the amount burnt will be;
55/4/11 = 5/4
5/4 inches of candle burnt in 1 hour
5/4 inches = b/t
So b inches burnt in t hours
5/4 = b/t
5t = 4b
What is the solution to the linear equation 4b + 6 = 2 - b+ 4
Final Answer: [tex]b = 0[/tex]
Steps/Reasons/Explanation:
Question: What is the solution to the linear equation [tex]4b + 6 = 2 - b + 4[/tex]?
Step 1: Simplify [tex]2 - b + 4[/tex] to [tex]6 - b[/tex].
[tex]4b + 6 = 6 - b[/tex]
Step 2: Cancel [tex]6[/tex] on both sides.
[tex]4b = -b[/tex]
Step 3: Subtract [tex]-b[/tex] from both sides.
[tex]4b + b = 0[/tex]
Step 4: Simplify [tex]4b + b[/tex] to [tex]5b[/tex].
[tex]5b = 0[/tex]
Step 5: Divide both sides by [tex]5[/tex].
[tex]b = 0[/tex]
~I hope I helped you :)~
Answer:
b = 0
Step-by-step explanation:
(Combine like terms): 4b + 6 = 2 - b + 4
4b + 6 = 6 - b
(Use Addition property of
equality to add b): 4b + b + 6 = 6
5b + 6 = 6
(Use Subtraction property of
equality to subtract 6): 5b + 6 - 6 = 6 - 6
5b = 0
(Divide both sides by 5): 5b = 0
5 5
b = 0factor completely 4x⁸+12x⁷-16x⁶-48x⁵

Answer:
3(n+4) = 12
Step-by-step explanation:
The sum of n and 4 is (n+4). Three times that sum is 3(n+4). When we say it "is 12", we mean it is equal to 12.
3(n +4) = 12

-35
35
-12
Answer:-35
Step-by-step explanation: 7x5 = 35, but since the 5 is a negative it’s -35
Answer:
-35
Step-by-step explanation:
whenever multiplying positive and negative integers, if one of the factors are negative, then the answer will be negative. if both are negative, the answer becomes a positive, and if both are positive, the answers stays positive.
in this case 7 is positive and 5 is negative so your anwers is -35

Which of these is equal to q?
A -p
B 0
C p
D 1/p
Answer:
C. p
Step-by-step explanation:
Given the expression p - q = 0
We are to find the value of q
Substract p from both sides;
p - q - p = 0 - p
-q = - p
Multiply both sides by -1
-(-q) = -(-p)
q = p
Hence the correct solution is q = p

suppose aaron earned 15.75 in interest for account A and 28.00 in interest for account B after 21 months if the simple interest rate is 3.0% for account A and 4.0% for account B wich account has the greater principle explain
Answer:
Principle for account B is greater.
Step-by-step explanation:
First of all, let us have a look at the formula for Simple Interest:
[tex]SI =\dfrac{PRT}{100}[/tex]
Where [tex]P[/tex] is the principle amount
[tex]R[/tex] is the Rate of interest per annum
[tex]T[/tex] is the time in years.
Time = 21 months = [tex]\frac{21}{12}\ yrs[/tex]
[tex]R_1 = 3\% \\R_2=4\%[/tex]
Let the Principles be [tex]P_1, P_2[/tex].
Using the formula for Simple Interest, we get:
[tex]SI_1=\dfrac{P_1\times 3\times 21}{100\times 12}\\\Rightarrow 15.75=\dfrac{P_1\times 3\times 21}{100\times 12}\\\Rightarrow P_1 = 300[/tex]
[tex]SI_2=\dfrac{P_2\times 4\times 21}{100\times 12}\\\Rightarrow 28=\dfrac{P_2\times 3\times 21}{100\times 12}\\\Rightarrow P_2 = 533.33[/tex]
Therefore, principle for account B is greater.
A=16.7
B=17
C=23
D=7
Answer:
17
Step-by-step explanation:
In this problem, you can use the Pythagorean Theorem to find the hypotenuse, which is x. The formula for the Pythagorean Theorem is: [tex]a^{2} +b^{2}=c^{2}[/tex], where a and b are the two lengths of the triangle, and c is the hypotenuse (which is x).
Steps:
-We know the two sides already, which are 15 and 8, so we can substitute a and b into the equation: [tex]15^{2} +8^{2}=c^{2}[/tex] (the c is the same as x, just letting you know)
-Then, simplify the equation to get: [tex]225+64=x^{2}[/tex] (I replaced c with x just so you can understand better that we are trying to find x, the hypotenuse)
-Add the 225 and 64 to get: [tex]289=x^{2}[/tex]
-Find the square root of both sides to get x by itself: [tex]\sqrt{289}=\sqrt{x^{2}[/tex]
-Evaluate the equation to get: [tex]\sqrt{289} =x[/tex] which simplifies to [tex]17=x[/tex]

Answer:
(7 , 5)
Step-by-step explanation:
Add all the x-axis then divide by 3
7 + 3 + 11 = 21
21/3 = 7
Add all the y-axis then divide by 3
9 + 3 + 3 = 15
15/3 = 5
So answer will be (7,5)
The coordinates of the centroid of triangle ABC.
(x, y)
Where,
x = Sum all the x-coordinates of the vertices ÷ 3
y = Sum o
The coordinates of the centroid is (7, 5).
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
The vertices of the triangle in the diagram below are:
A(7,9), B(3,3), and C(11,3).
Now,
The coordinates of the centroid of triangle ABC.
(x, y)
Where,
x = Sum all the x-coordinates of the vertices ÷ 3
y = Sum of the y-coordinates of the vertices ÷ 3
Now,
x = 7 + 3 + 11 / 3 = 21/3 = 7
y = 9 + 3 + 3 / 3 = 15/3 = 5
Now,
The coordinates of the centroid is (7, 5).

pls :,) i suck at math
Answer:
60%
Step-by-step explanation:
The original was $20 to $12, so if you divide both prices by 2 (to make one side 10 and the other the simplified percentage) you get:
10 to 6.
Percentages are typically x% out of 100, so if you multiply both by 10 you get:
100 to 60. All you have to do now is change the format to percentage instead of a fraction (60/100) and the answer is 60%.

FG is the geometric mean of which two segments
Answer:
EG and GH
Step-by-step explanation:
FG is the geometric mean of EG and GH segments.
FG is the geometric mean of EG and GH by using the Right triangle altitude theorem.
Important information:
The given figure of a triangle EFH.Right triangle altitude theorem:According to the Right triangle altitude theorem, if an altitude is drawn on the hypotenuse of a right triangle, then the altitude of a right triangle is the geometric mean of the two segments of the hypotenuse.
From the given figure it is clear that,
Triangle EFH is a right triangle because angle F is a right angle.FG is the altitude on the hypotenuse.Two segments of the hypotenuse are EG and GH.Using the Right triangle altitude theorem, we get FG is the geometric mean of EG and GH.

Step-by-step explanation:
3 hours 55 minutes
=3×60+55
=235 and
235-215 ( for preheating minutes)
220
So
20 minutes…=48 cookies
1. ". =48/20 "
220 ". =48/20×220 "
=12/5×220 "
= 528 "
Answer:
well im not sure but i got 220
Step-by-step explanation:
so you convert the 3 hours and 55 minutes into minutes so
3*60=180
180+55=235
235-15=220
(for the preheating part)
220/48=4.583333333
4.583333333*48=(about)220 (actual number is 219.999999984)
so 220 cookies
