Answer: The required value of z is 6.
Step-by-step explanation: Given that 5+2z is 3 more than 3z-4.
We are to find the value of z.
According to the given information, the equation expressing the given statement mathematically can be written and solved as follows:
5+2z=(3z−4)+3
⇒5+2z=3z−1
⇒3z−2z=5+1
⇒z=6.
Thus, the required value of z is 6.

The sum of a number and six is seven times the number.
Which is a translation of the sentence into an equation?
n + 6 = 7n
n − 6 = 7n
7(n + 6) = n
n = 7n + 6
Answer:
n + 6 = 7n
Step-by-step explanation:
"The sum of a number and six" would mean the number plus 6: n+6 and "is seven times the number" indicates that it would be equal to the product of 7 for n: 7n. According to this, the answer is that the translation of the sentence into an equation is: n+6=7n.
n − 6 = 7n is not right because the statement says the sum of a number and six.
7(n + 6) = n is not right because the statement indicates that seven multiplies n on the right side as it says seven times the number.
n = 7n + 6 is not right because the statement says the sum of a number and six which would be on the left side and that this would be equal to seven for n.

What are the vertex and x-intercepts of the graph of the function given below?
y = x2 - 2x-35
A. Vertex: (1, -36); intercepts: x = 7,-5
B. Vertex: (0,0); intercepts: x= -4,-5
C. Vertex: (7,5); intercepts: x = 7,8
D. Vertex: (1, -25); intercepts: x = 6,-4
Answer:the answer is A
Step-by-step explanation:
The vertex and x-intercepts of the graph of the function y = x²- 2x-35 is (1, -36) and intercepts: x = 7,-5, option A is correct.
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
The x-coordinate of the vertex can be found using the formula x = -b/2a, where a and b are the coefficients of the x² and x terms, respectively. In this case, a = 1 and b = -2, so x = -(-2)/(2×1) = 1.
Lets find the y-coordinate of the vertex.
To find the y-coordinate of the vertex, we substitute the x-coordinate we found in step 1 into the equation and evaluate.
y = (1)² - 2(1) - 35 = -36
So the vertex is at (1, -36).
Now find the x-intercepts.
To find the x-intercepts, we set y = 0 and solve for x.
0 = x² - 2x - 35
This equation can be factored as (x - 7)(x + 5) = 0.
So the x-intercepts are at x = 7 and x = -5.
Therefore, the vertex and x-intercepts of the graph of the function y = x²- 2x-35 is (1, -36) and intercepts: x = 7,-5, option A is correct.

Which parallelogram has an area of 60 square units?
Answer:
The answer is B
Step-by-step explanation:
Multiply base•height
Finding the area of each parallelogram, applying the formula, it is found that the parallelogram D has an area of 60 square units.
---------------------------
Similarly to a rectangle, the area of a parallelogram is given by height multiplied by base, that is:
[tex]A = hb[/tex]
---------------------------
In item A, the height is of 15 units and the base is of 10 units, thus, the area, in square units, is of [tex]15 \times 10 = 150[/tex].In item B, the height is of 6 units and the base is of 10.2 units, thus, the area, in square units, is of [tex]6 \times 10.2 = 61.2[/tex].In item C, the height is of 15 units and the base is of 15 units, thus, the area, in square units, is of [tex]15 \times 15 = 225[/tex].In item D, the height is of 10 units and the base is of 6 units, thus, the area, in square units, is of [tex]10 \times 6 = 60[/tex], which means that this is the correct option.A similar problem is given at https://brainly.com/question/14099239
A rectangular hotel room is 4 yards by 5 yards. The owner of the hotel wants to recarpet the room with carpet that costs $51.92 per square yard. How much will it cost to recarpet the room?
Answer:
it will cost him $2204 to recarpet the room.
Step-by-step explanation:
The floor of the room is rectangular. The formula for determining the area of a rectangle is expressed as
Area = length × width
The rectangular hotel room is 4 yards by 7 yards. It means that the area of the rectangular floor would be
Area = 4 × 7 = 28 square yard.
If the cost of the carpet $58.00 per square yard, the total that it will cost to recarpet the room would be
38 × 58.00 = $2204

Write the slope-intercept form of the equation of the line through the given point with the given slope. through: (-5, -1); slope = negative 3 over 5
Answer:
The slope-intercept form of the equation of the line is [tex]y = -\frac{3}{5} \cdot x -4[/tex].
Step-by-step explanation:
We know that the slope-intercept form of the equation of the line is represented by:
[tex]y = m\cdot x + b[/tex]
Where:
[tex]x[/tex] - Independent variable, dimensionless.
[tex]y[/tex] - Dependent variable, dimensionless.
[tex]m[/tex] - Slope, dimensionless.
[tex]b[/tex] - y-Intercept, dimensionless.
From statement we find that [tex]m =-\frac{3}{5}[/tex]. If [tex]x = -5[/tex] and [tex]y = -1[/tex], the value of the y-intercept is:
[tex]-1 =-\frac{3}{5}\cdot (-5)+b[/tex]
[tex]-1 = 3 + b[/tex]
[tex]b = -4[/tex]
The slope-intercept form of the equation of the line is [tex]y = -\frac{3}{5} \cdot x -4[/tex].

Find the median and mean of the data set below: 35 , 28 , 19 , 18
Answer:
Hi there!
Your answer is:
Median: 23.5
Mean: 25
Step-by-step explanation:
The mean is the average of all the numbers in your dataset. You determine this by adding all the numbers together and dividing by the # of numbers in your set!
35+28+19+18 = 100.
100/4 = 25
The median is the middle number of your data set! This is determined by counting off the numbers from each side of the equation after setting them in order from least to greatest. If there are 2 remaining, you must find the average of those!
35 , 28, 19 , 18 from least to greatest is
18, 19, 28, 35

4x-7=7x-61 solve for x
Answer:
x = 18Step-by-step explanation:
4x - 7 = 7x - 61
Subtract 7x from both sides
That's
4x - 7x - 7 = 7x - 7x - 61
- 3x - 7 = - 61
Add 7 to both sides
We have
- 3x + 7 - 7 = - 61 + 7
- 3x = - 54
Divide both sides by - 3
That's
[tex] \frac{ - 3x}{ - 3} = \frac{ - 54}{ - 3} [/tex]We have the final answer as
x = 18Hope this helps you
Answer: 18
Step-by-step explanation:
4x - 7 = 7x - 61
+61 +61
4x + 54 = 7x
divide both sides by 4
x + 27/2 = 7/4x
-x -x
27/2 = 3/4x
divide both sides by 3/4
x = 18
