Step-by-step explanation:
The sum of one-third a number and twenty-five is as much as twice the number
Answer:
The number is 15
Step-by-step explanation:
1/3(number) + 25 = 2(number)
subtract 1/3(number) from each side
25 = 2(number) - 1/3(number)
25 = 6/3(number) - 1/3(number)
25 = 5/3(number)
multiple each side by 3/5, which is the reciprocal of 5/3
25(3/5) = number
15 = number

14x-10=3 (4+x); solve for x
Answer:
x = 2
Step-by-step explanation:
So we are given the equation 14x - 10 = 3(4 + x) and we are asked to solve for x. To this, we will have to get x by itself on one side and a value on the other side.
14x - 10 = 3(4 + x)
Distribute the 3 on the right side.
14x - 10 = 12 + 3x
Add 10 to both sides.
14x = 22 + 3x
Subtract 3x from both sides.
11x = 22
Divide both sides by 11.
x = 2
So now we got the answer of x = 2.
I hope you find my answer helpful.
Answer:
x = 2
Step-by-step explanation:
14x - 10 = 3(4+x)
=> 14x -10 = 12 + 3x
=> 14x - 3x = 12 + 10
=> 11x = 22
=> x = 22/11
=> x = 2

Pete ate 3/7 of a pizza if Pete ate 9 slides of the pizza how many slices were ther all together
Answer:
21 slices
Step-by-step explanation:
given:
3/7 of a pizza ----> represents 9 slices
hence,
1/7 of a pizza -------> represents 9/3 = 3 slices
therefore
a whole pizza
= 7/7 of a pizza -------> represents 3 x 7 = 21 slices
Answer:
Hi there!!
Your answer is:
21 slices
Step-by-step explanation:
3/7ths = 9 slices
× 7/3
1 whole pizza = 21 slices
This is called the multiplicative inverse! 3/7 × 7/3 = 1

The value of x in the given expression is -a/6
What is expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given is an expression, 4 = 6x / a + 5
Solving for x, we get,
4 = 6x / a + 5
Subtracting 5 both the side,
6x / a = -1
Multiplying by a both the sides,
6x = -a
Dividing by 6 both sides,
x = -a/6
Hence, the value of x is -a/6

Find where the lines y =-3x + 2 and y = 5x 6 cross in the coordinate plane.
Answer:
(1, -1)
Step-by-step explanation:
Given lines
y = -3x + 2y = 5x - 6They cross at:
-3x + 2 = 5x - 65x + 3x = 2 + 68x = 8x = 1The y coordinate is:
y = -3*1 + 2 = -1So the lines cross at point (1, -1)
What the answer to this math problem 6x-8=4(x+2)-7 ?
Answer:
x = 9/2
Step-by-step explanation:
6x - 8 = 4(x + 2) - 7
Distribute on the right side.
6x - 8 = 4x + 8 - 7
Combine like terms on the right side.
6x - 8 = 4x + 1
Add 8 to both sides. Subtract 4x from both sides.
2x = 9
Divide both sides by 2.
x = 9/2

Explain why the function is discontinuous at the given number
Answer:
left limit = 2 ≠ 1/2 = right limit
Step-by-step explanation:
A function is discontinuous if the limit of the function value approaching the point from the left is different than the limit approaching from the right.
Here, the left limit is 2 and the right limit is 1/2. The limits are different, which is why the function is discontinuous at x=-1.
Identify the property used in each step of solving the inequality 3x – 2 > -4.
Step Justification
3x - 2-4 Given
3x > -2
X>-2/3
Answer:
2) is addition property
3) is multiplication property
Step-by-step explanation:
The addition property and division properties are used to solve the inequality.
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
The given inequality is 3x – 2 > -4.
Three times of x minus two is greater than minus four
By using addition property we add +2 on both the sides
3x – 2 +2 > -4+2
3x>-2
By using division property we divide +3 on both the sides
x>-2/3
Hence, the addition property and division propertys are used to solve the inequality.
