. When 2 times a number is increased by 4,
the answer is the same as when 25is
decreased by the number. Find the number.
Answer: The number is 7
Step-by-step explanation:
Let x be the [number]
Rephrase the expression
2 times a number is increased by 4, it is the same as 25 decreased by the number
2x+4=25-x
Calculate
Given
2x+4=25-x
Add x on both sides
2x+4+x=25-x+x
3x+4=25
Subtract 4 on both sides
3x+4-4=25-4
3x=21
Divide 3 on both sides
3x/3=21/3
x=7
Hope this helps!! :)

-20x - 16y = -20
10x + 8y = 10
Answer: None
Step-by-step explanation:
You have to either solve for x or y by getting x/y in both equations the same value to cancel them out. In my steps I will solve for x:
-20x - 16y = -20
10x + 8y = 10
----------
1.) Multiply 10x + 8y = 10 by 2
-20x - 16y = -20
20x + 16y = 20
2.) Cancel out values
All parts cancel out.

Given the equation 25 + 7x = 11
x = -2
x = 2
X = -14
x = 14
Answer:
x = -2
Step-by-step explanation:
Isolate the variable (or x) by subtracting 25 from both sides.
We do this and get 7x = -14
Divide both sides by 7 and we get x = -2
-3x-5=16
what is x in the equation
Answer:
x=−7
Step-by-step explanation:
Step 1: Add 5 to both sides.
−3x−5+5=16+5
−3x=21
Step 2: Divide both sides by -3.
−3x/−3=21/−3
Answer:
x = -7
Step-by-step explanation:
Hello.
I can help.
To solve algebraic equations all you need to do is get rid of everything on the side of the x except the x.
Lets look at your problem.
-3x - 5 = 16
An important thing to note is we are going to get rid of things on the left side of the = by doing the opposite of what they're doing.
If it is addition we do subtraction
If it is division we do multiplication
and so on.
ALSO
Whatever we do on the left side of the = we must do the same thing to the number on the right.
Now, let us start trying to solve this.
You always want to start with the number that is alone without the variable / letter.
So :
-3x - 5 = 16
Since it is -5 lets add 5 to make it 0 and get rid of it.
-3x - 5 = 16
+5 +5
(Remember to do it to the other side of the = too)
Now we have :
-3x = 21
Now we want to get rid of the 3 attached to the x. And since these two are multiplying we need to divide the -3 by itself to make it 1. Since one number divided by itself is 1.
So like this :
-3x = 21
/-3 /-3
NOTE : When you are dividing or multiplying negative numbers there is an important key to be aware of. Here is a short key to go off of :
- x - = +
- x + = -
So a negative times a negative will be a positive.
While a positive times a negative, the negative will over ride the positive and the answer will be negative.
Going back to the equation, here is what we do :
-3x / -3 = +x (Not negative)
And :
21 / -3 = -7 (Is negative)
So now our equation is :
x = -7
And this is our final answer.
I hope this helped.

Mr. Dunbar takes his wife out to dinner at Macados to celebrate the holidays. Their total bill was $48.36 but he had a coupon to save 15% off. He had a great waitress so he planned to leave a 25% tip. How much did Mr. Dunbar spend to take his wife out for dinner?
Answer:
$51.38 or $60.45
Step-by-step explanation:
$48.36 minus 15 percent is $41.10. If you're tipping the waitress 25 percent from that price, then it would be $51.38. If you're tipping the waitress 25 percent from the original price, it would be $60.45.

Answer:
x = 104 degrees
y = 76 degrees
z = 104 degrees
quadrilateral have to add up all of their interior angles to 360 degrees.
x and c are opposite interior angles. after finding that you have to add those 2 together (208) and subtract that from 360. You should get 152. However andgle B (angle y) and angle D are also opposite interiors so you divide 152 by 2 and get 76 degrees.
Also a straight line is 180 degrees so you subtract the degrees of D by 100 to get angle z.
Answer:
m∡x = 104°
m∡y = 76°
m∡z = 104°
Step-by-step explanation:
m∡A ≅ m∡C
m∡B ≅ m∡D
to find m∡B: 2(104) + 2y = 360
208 + 2y = 360
2y = 152
y = 76
m∡z: 180° - 76° = 104°
the owner of a pet shop buys budgie bells in packs of 30 bells. she pays 12p per bell. She sells 3/5 of the bells for 50p each and the rest for 40p each. How much profit does she make on the whole pack of budgie bells?
Answer: 1020p
Step-by-step explanation:
The total cost of the bells will be:
= 12p × 30 = 360p
She sells 3/5 of the bells for 50p each. This will be:
= (3/5 × 30) × 50
= 18 × 50p
= 900p
She sells the remaining 2/5 for 40p each. This will be:
= (2/5 × 30) × 40
= 12 × 40
= 480p
Then, total revenue will be:
= 900p + 480p
= 1380p
Profit = Revenue - Cost
= 1380p - 360p
= 1020p

If -3x + 5 > 4, which of the following cannot be a value of x? 7.11B-S)
A -3
B -1
C о
D 4
Answer:
D
Step-by-step explanation:
Solving the inequality
- 3x + 5 > 4 ( subtract 5 from both sides )
- 3x > - 1
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative value.
x < [tex]\frac{1}{3}[/tex]
The only value not less than [tex]\frac{1}{3}[/tex] is 4 → D

Does the equation 5(x – 3) = 10x–15 have one solution, infinitely many solutions, or no solution?
Answer:
infinitely many solutions
Step-by-step explanation:
The equation 5(x - 3) = 10x - 15 has one solution, which is x = 0.
Let's simplify the given equation:
5(x - 3) = 10x - 15
Distribute the 5 on the left side:
5x - 15 = 10x - 15
Now, let's isolate the variables on one side by subtracting 5x from both sides:
-15 = 5x - 15
Next, add 15 to both sides:
0 = 5x
Divide both sides by 5:
0/5 = 5x/5
0 = x
Therefore, the equation simplifies to 0 = x. This means that x is equal to 0.
So, the equation 5(x - 3) = 10x - 15 has one solution, which is x = 0.

The area of this rectangle is at most 400 square centimeters. Write and solve an inequality to represent the
possible values for the height, h, for this triangle. Show all steps of your work
Answer:
1ft≤h≤25ft
Step-by-step explanation:
The area of a rectangle is expressed as;
Area = Length * height
A = Lh
If the area of a rectangle is at most 400 square centimeter, this is expressed as;
A ≤400
≤ means at most that is the area of the rectangle cannot be greater than 400
Substitute the given value into the inequality expression
Lh ≤ 400
Given
L = 16
16h ≤ 400
Divide both sides by 16
16h/16 ≤ 400/16
h ≤ 400/16
h ≤ 25
Hence the possible values of the height are with the range 1ft≤h≤25ft since we cannot have a negative value for the dimension
