Find the value of x:
Answer:
x = 3
Step-by-step explanation:
These angles are vertical angles. Vertical angles equals to on another but on the opposite side. Since they equal to another you do:
(10x + 1) = (12x - 5)
Add 5 on both sides:
10x + 6 = 12x
Subtract 10x on both sides:
6 = 2x
Divide 2 on both sides:
3 = x
Answer:
(10x+1)°=(12x-5)°. [vertically opposite angle]
1+5=12x-10x
6= 2x
3=x
therefore,x=3

NO LINKS PLEASEE!! IM BEGGING YOU NO LINKSS!!!
Answer:
A = (1/2)Pa = Pa/2
You can multiply both sides by 2 to eliminate the fraction on the right side:
2A = 2(Pa/2) = Pa
Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:
(2A)(1/a) = 2A/a = (Pa)(1/a) = P
Rewriting:
P = 2A/a
You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.

Money was placed in a savings account and earned 3/4 % interest paid annually. Samantha, Tony and Anuyia each wrote an equation to show the amount of money in the account after one year with a balance of M dollars. T represents the total amount of money in the account.
Samantha’s Equation: T = 1.075M
Tony’s Equation: T = M + 0.0075M
Anuyia’s Equation: T = M(1 + 0.0075M)
Since none of the equations were written the same, they decided to see if their equations would give the same answers by using a $75 balance. Solve this problem using each student’s equation.

Maggie is buying a jacket. The expression shown represents the sales tax on the jacket price, j.
0.08j
Write an expression in terms of j to represent the total amount that Maggie spends on the jacket, including tax.
Answer: 1.08j
Step-by-step explanation: if we add 8% of something to itself, we now have 108%, right
1.08j
I’m not 100% sure tho
The expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is given that the cost of the jacket is j, while the tax on the jacket is 0.08j. therefore, the total cost of the jacket can be written as the sum of the cost of the jacket and the tax on the jacket.
Thus, the total cost of the jacket = Cost of jacket + Tax on the jacket
= j + 0.08j
= 1.08j
Hence, the expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.
