7(m+5) = 21
What is it?
Answers
Answer:
m = -2
Step-by-step explanation:
Look at the attached image. First, we divide both sides by 7 to get m + 5 = 3. Now, we subtract 5 from both sides to get m = -2. Now, we substitute m for -2. As we can see, it checks out.
The solution of expression is,
m = - 2
We have to give that,
An expression to solve,
7 (m + 5) = 21
Now, simplify the expression as,
7 (m + 5) = 21
Divide both sides by 7,
m + 5 = 21 / 7
m + 5 = 3
Subtract 5 both side,
m = 3 - 5
m = - 2
So, The solution is, m = - 2

150 * 0.40 = $60 off
150 - 60 = $90
Solution: you pay $90
Answer:
$94.50
Step-by-step explanation:
150 x .30 = 45, so you can $45 off.
105 x .1 = 10.5 so you can take another $10.50 off.

A 20 foot ladder is placed against a wall at a 75 degree angle with the ground. The wall is perpendicular to the ground.
PART A: How high on the wall, in feet, will the ladder reach? Round your answer to the nearest tenth. Show your work.
PART B: What is the distance, in feet, from the wall to the base of the ladder? Show your work.
Answers
Answer:
A. 19.3ft B. 5.2ft
Step-by-step explanation:
So the ladder leaning against the wall forms a triangle. The hypotenuse of
triangle is the ladder (20) and the angle given between ladder an ground is 75 degrees. Use trig to find the height of the wall which is the leg of the triangle.
Sine of Angle is opposite side/hypotenuse
Cosine of Angle is adjacent side/hypotenuse
so Sine of 75 degrees = Wall height/20
Wall height = 20 times Sine of 75 degrees
Sine of 75 degrees = .9659
20 times (.9659) = 19.3ft
So now use Cosine to find the other leg of the triangle (the distance between the bottom of ladder to the wall)
Cosine of 75 degrees = Distance wall to base of ladder / 20
Cosine of 75 degrees = .2588
20 times (.2588) = 5.2ft

F = k/d^2
Step-by-step explanation:
We can see from the question that the force of attraction F is proportional to the inverse of the square of the distance separating the bodies, d.
So we have;
F α 1/d^2
So, introducing a constant of proportionality k,
F = k/d^2
Hence the formula connecting F and d is; F = k/d^2

x is a negative integer which is the largest
7x+4
x-4
5x
-5x
Answers
Answer:
-5x
Step-by-step explanation:
Remember, if you multiply a negative number by a negative number, you will get a positive number, and positive numbers are greater than negative numbers. In this case, if I were to multiply each of these expressions with -1, I would get the following:
7(-1)+4=-3
-1-4=-5
5(-1)=-5
-5(-1)=5
And I'm sure you can imply how these values will correspond to other negative values. Basically, the last expression gives us a positive answer, which is larger than the others (which give a negative answer).
-5x will be the largest among the options since x is the negative integer.
What is a negative integer?On the number line, a negative integer is an integer that is to the left of zero. It is not equal to zero.
Given, x is a negative integer, all given options will become negative except " -5x". written with a minus sign. a number smaller than zero, but not a fraction or a decimal fraction.
Since for any value of x, all the given options will be negative.
Therefore, Due to the fact that x is a negative integer, -5x will be the largest selection.

The ratio of number of students who watched basketball most often to the total number of students is 5 to 20 or 5:20
Step-by-step explanation:
Because 5 students named basketball as the spot the watch most often on television, while 8 of them said baseball and 7 said football. To find the total numbers of students we have to add all the students together so 8 + 7 is 15 and 15 + 5 is 20.

The black graph is the graph of y=f(x). Choose the equation for the red graph.
Answers
Answer:
y-1 = f(x)
Step-by-step explanation:
Here, we want to choose the equation for the ref graph
The red graph as we can see is above the black
This means it is more positive
The difference between the two is just 1 unit
By the addition of 1 to the y-value of the black graph, we get the red
Thus, we have that;
y- 1 = f(x)
