solve for x.
7x/2+5=8
Answer:
x=6/7
Step-by-step explanation:
7x÷2+5=8
divide by 2 on both sides:
7x/2+5=8(it's a fraction)
subtract 5 on both sides
7x÷2=3
multiply 2 on both sides
7x=6
divide by seven on both sides
x=6/7

Help me. Two numbers have a sum of 30. Half of their difference is 7. Find the numbers.
Answer:
the answer is x equals 22 and y equals 8
Step-by-step explanation:
first equation is x+y=30
Second equation is x-y/2=7 that simplify's to x-y=14
then you add then so they will cancel out and you are left with 2x=44 so divide two by both sides which gives x=22
then you subsitute the 22 in the first equation. It will be 22+y=30 then you subtract 22 from the 30 that gives you y=8
so the two numbers are 22 and 8
Hope this helps!!!!
The numbers satisfying the given conditions are 22 and 8.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
We have the following problem -
Two numbers have a sum of 30. Half of their difference is 7.
We can write the equations as -
x + y = 30
1/2(x - y) = 7
Rearranging, we get -
y = - x + 30
y = x - 14
Plot the graph, the point of intersection is the solution. The number will be 22 and 8.
Alternativelyy = - x + 30
y = x - 14
Equating both, we get -
- x + 30 = x - 14
30 + 14 = 2x
2x = 44
x = 22
and
y = 22 - 14
y = 8
Therefore, the numbers satisfying the given conditions are 22 and 8.

What is the slope of the line?
y - 3 = 5(x-2)
Answer:
5
Step-by-step explanation:
To better see what the slope is (the coefficient of x), write it in slope-intercept form, y=mx+b. The slope-intercept form of [tex]y -3 = 5(x-2)[/tex] is [tex]y=5x-7[/tex]. The slope is the coefficient of x, which is 5.

Writing a Linear Function to Model a Scenario Pedro works as a newspaper deliverer. He receives a base pay plus an additional amount per newspaper delivered. Last week, Pedro delivered 5 newspapers and earned $37.50. This week, he delivered 20 newspapers and earned $75. Let x equal the number of newspapers Pedro delivers and y be the earnings he receives in dollars. Which linear function models the scenario?
Answer: y= 25+2.5x
Step-by-step explanation:
Let a = base pay , b = additional amount per newspaper.
Given: Last week, Pedro delivered 5 newspapers and earned $37.50.
i.e. 37.50=a+5b (i)
This week, he delivered 20 newspapers and earned $75.
i.e. 75=a+20b (ii)
Eliminate (i) from (ii)
37.50=15b
[tex]\Rightarrow\ b=\dfrac{37.50}{15}\\\\\Rightarrow\ b=2.5[/tex], i.e. additional amount per newspaper= $2.5
Put b= 2.5 in (i)
[tex]37.50=a+5(2.5)\\\\\Rightarrow\ 37.50=a+12.5\\\\\Rightarrow\ a=37.50-12.5\\\\\Rightarrow\ a=25[/tex], i.e. base pay = $20
Let x= Number of newspapers Pedro delivers.
y= Earnings he receives in dollars.
y= 25+2.5x will be the required function.
Why can you use the constant of proportionality with any representation?
Answer:
The number k is called the constant of proportionality. One important way of thinking about this constant k is that it tells us how much y increases by if we increase x by exactly 1. to express that y is directly proportional to x.Proportionality constant can be used with any representation to determine how a variable is changing with respect to others.
Variation is a method comparing the nature of a variable with another variable using a constant called the proportionality constant
For instance, if a variable y is directly proportional to x, it is expressed as;
y ∝ x
y = kx
k is the proportionality constant relating y to x and shows that as the value of y is increasing, the value of x is also increasing and vice versa.

By 2 2 1 S ut at , where S is the distance traveled, u is the initial velocity, a is the acceleration, and t is the time. Which equation represents a in terms of the other variables?
Answer:
Step-by-step explanation:
Given the equation of motion;
S = ut + 1/2 at² where;
u is the initial velocity,
a is the acceleration, and;
t is the time.
We are to express a in terms of u, t and S
Making a the subject of the formula;
S = ut + 1/2 at²
S-ut = 1/2at²
2(S-ut) = at²
a = 2(S-ut)/t²
Hence the acceleration a in terms of other variables is expressed as a = 2(S-ut)/t²

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given the Parameters as;
L = 0.5, W = 0.2, and H= 0.1
