Answer:
t=-1Step-by-step explanation:
To find the value of t, isolate it on one side of the equation.
[tex]\sf{\dfrac{3}{2}+t=\dfrac{1}{2}}[/tex]
First, you subtract by 3/2 from both sides.
[tex]\Longrightarrow: \sf{\dfrac{3}{2}+t-\dfrac{3}{2}=\dfrac{1}{2}-\dfrac{3}{2}}[/tex]
Solve.
1/2-3/2
1-3/2
1-3=-2
-2/2
Divide.
-2/2=-1
[tex]\Longrightarrow: \boxed{\sf{t=-1}}[/tex]
Therefore, the solution is t=-1, which is our answer.
I hope this helps, let me know if you have any questions.
STEP BY STEP EXPLANATION;
1.To solve the equation,the least common multiple of the denominators must be found.
LCM=2
Therefore,
3/2 +t =1/2
2.Each term must be multiplied by the LCM.
i.e
2(3/2)+2(t)=2(1/2)
3+2t=1
2t=1-3 ( subtracting 3 from each side of the equation)
2t=1-3
2t/2=-2/2 (dividing both sides of the equation by the co-efficient of t)
t=-1
Find the area and perimeter
for each polygon.
Answer:
5. P = 23 m
A = 15 [tex]m^{2}[/tex]
6. P = 24.4 in
A = 15.3 [tex]in^{2}[/tex]
Step-by-step explanation:
Area formula of a triangle is A = 1/2 bh
Area formula of a parallelogram is A = bh
5. The height of a triangle is perpendicular to the base.
A = 1/2 * 10 * 3
A = 15 [tex]m^{2}[/tex]
6. The height of the parallelogram is also perpendicular to the base.
A = 9 * 1.7
A = 15.3 [tex]in^{2}[/tex]
Perimeter means you add all the side lengths.
5. The side lengths are 5m, 8m, and 10m. Adding those together, you get 23m.
6. A parallelogram has congruent opposite sides. That means your side lengths are 9 in, 3.2 in, 9 in and 3.2 in. Adding those together, you get 24.4 in.

Suppose that the base salary of a salesperson is $30,000 per year. The salesperson gets an additional $50 for every sale. Let x represents the number of sales. How can we model the scenario with a linear function? How many items does the salesperson need to sell to earn $50,000
Answer:
See below
Step-by-step explanation:
Salary (y) = 30 000 + 50 x
y = 30 000 + 50x where x is the number of sales
How many sales for 50 000 ?
50 000 = 30 000 + 50 x
20 000 = 50 x
x = 400 sales
I. Model Problems
A linear model is a linear equation that represents a real-world
scenario. You can write the equation for a linear model in the same way
you would write the slope-intercept equation of a line. The y-intercept
of a linear model is the quantity that does not depend on x. The slope is
the quantity that changes at a constant rate as x changes. The change
must be at a constant rate in order for the equation to be a linear model.
Example 1 A machine salesperson earns a base salary of $40,000 plus
a commission of $300 for every machine he sells. Write an equation
that shows the total amount of income the salesperson earns, if he sells
x machines in a year.
The y-intercept is $40,000; the salesperson earns a $40,000 salary in a
year and that amount does not depend on x.
The slope is $300 because the salesperson’s income increases by $300
for each machine he sells.
Answer: The linear model representing the salesperson’s total income
is y = $300x + $40,000.
Linear models can be used to solve problems.
Example 2 The linear model that shows the total income for the
salesperson in example 1 is y = 300x + 40,000. (a) What would be the
salesperson’s income if he sold 150 machines? (b) How many
machines would the salesperson need to sell to earn a $100,000
income?
(a) If the salesperson were to sell 150 machines, let x = 150 in the linear
model; 300(150) + 40,000 = 85,000.
Answer: His income would be $85,000.
(b) To find the number of machines he needs to sell to earn a $100,000
income, let y = 100,000 and solve for x:

A rectangular table is six times as long as it is wide. If the area is 150 ft2, find the length and the width of the table.
The width of the table is
The length of the table is?
Answer:
Length = 30ft, Width = 5ft
Step-by-step explanation:
Let x be the width.
Area of Rectangle = Length * Width
Given from the information in the question,
Length = 6x ft
Width = x ft
Substitute the values into the formula:
6x * x = 150
[tex]6x^{2}[/tex] = 150
[tex]x^{2} =\frac{150}{6}[/tex]
[tex]x^{2} =25[/tex]

x = 5 ft.
Therefore,

A ship left a port and sailed east at the rate of 30 miles per hour. One hour later, a second ship left the same port at the rate of 40 miles per hour, also traveling east. In how many hours did the second ship overtake the first ship?
Answer:
3 hours
Step-by-step explanation:
When the ships meet each other, that means the the distance travelled for both ships are the same, that is where the 2nd ship will overtake the ship.
Distance = Speed * Time
So, given information from the question, and letting x be the time in hours (from when the 1st ship departs), we can deduce:
Distance travelled of 1st ship = Distance travelled of 2nd ship
30x = 40(x-1)
30x = 40x - 40
-10x = - 40
x = [tex]\frac{-40}{-10}[/tex]
= 4
Since we are calculating based on the 2nd ship,
Time taken for 2nd ship to overtake first ship = x - 1 = 4 - 1 = 3 hours.

Algebraic expressions are mathematical statements that consist of both number(s) and alphabet(x). Thus the number of stamps in the book is 66[tex]\frac{43}{60}[/tex] (67).
Algebraic expressions are mathematical statements that consist of both number(s) and alphabet(x). Majorly, the alphabet in the expression is referred to as the unknown value which has to be determined.
When the power of any of the alphabets contained in an algebraic expression is more than one, then it can be referred to as a polynomial.
In the given question, let the number of stamps in the book be represented by N.
So that;
N - 5/12 + 24 + 15 + 3/10 + 27 = 0
N - (5/12 + 24 + 15 + 3/10 + 27) = 0
N - [tex]\frac{8006}{120}[/tex] = 0
N - 66[tex]\frac{43}{60}[/tex] = 0
N = 66[tex]\frac{43}{60}[/tex]

Given the data in the question;
Angle of elevation θ = 35°Distance between the person and the building | Adjacent = 80ftHeight of the person h = 4ft.Height of the building from the eye level | opposite = xSince the scenario depicts a right angle triangle, we use trigonometric ratio.
tanθ = Opposite / Adjacent

Substitute given into the equation,
tan( 35 ) = x / 80ft
x = tan( 35 ) × 80ft
x = 0.7002075 × 80ft
x = 56ft
Now, to get the height of the building, we add the height of the person and the height of the building from the eye level of the person.
Height of building = x + 4ft
Height of building = 56ft + 4ft
Height of building = 60ft

Step-by-step explanation:
It will take 102 more payments
8.5 years
Interest will be $26,239
It would take approximately 15 years to pay back the loan of 95000 which is compounding monthly and the rate of interest is 6%.
What is compound interest?Compound interest is basically the interest which is calculated on the primcipal with addition to aggregate interest. The formula of sum after compounding is as under:
S=P[tex](1+r/n)^{nt}[/tex] in which P is principal amount, r is rate per annum, n is number of times of compounding and t is time period.
How to calculate time?We have been given that the amount of loan is $95000, installment is $1200 , rate of interest is 6% and it is compounded monthly.
First of all we have to find the effective rate=6%/12=0.005.
The future value of 95000 at a rate of 6% compunded monthly should be equal to the amount of all installments. So,
95000[tex](1+0.005)^{12n}[/tex]=12*1200*n
95000[tex]1.005^{12n}[/tex]=14400n
[tex]1.005^{12n}[/tex]=14400n/95000
[tex]1.005^{12n}[/tex]=0.1515n
We have to make graph of this to find the value of n which after graphing will come approx 15.
