PLEASE HELP ,,,,1. If AMNP is an equilateral triangle, find the values of x
and y.
An equilateral triangle is a triangle in which all three sides have the same length[tex].[/tex]
⭆ 14 = 3x - 4
⭆ 3x = 14 + 4
⭆ 3x = 18
⭆ x = 18/3
⭆ x = 6
In equilateral triangle, all three internal angles are also same and each are of 60°.
⭆ 5y - 5 = 60
⭆ 5y = 60 + 5
⭆ 5y = 65
⭆ y = 65/5
⭆ y = 13
★ Final answer :
x = 6y = 13Hope It Helps!Answer:
x = 6y = 13Step-by-step explanation:
equilateral triangle, all sides are equal,
MN = MP
14 = 3x - 4
x = 18/3
x = 6
internal angles are also equal.
5y - 5 = 60 (180/3 = 60)
5y = 65
y = 13
Newton has 10 more dimes than nickels. He has
twice the number of quarters than nickels. If he
has $6.20, how many of each coin does he have?
Given:
Newton has 10 more dimes than nickels.
He has twice the number of quarters than nickels.
Total amount he has = $6.20.
To find:
The number of each coin.
Solution:
Let the number of nickels be x.
Newton has 10 more dimes than nickels.
Dimes = x+10
He has twice the number of quarters than nickels.
Quarters = 2x
We know that, 1 nickel = $0.05, 1 dime = $0.10 and 1 quarter = $0.25.
Total amount he has is $6.20.
[tex]x\times 0.05+(x+10)\times 0.10+2x\times 0.25=6.20[/tex]
[tex]0.05x+0.10x+1+0.50x=6.20[/tex]
[tex]0.65x=6.20-1[/tex]
[tex]0.65x=5.20[/tex]
Divide both sides by 0.65.
[tex]x=\dfrac{5.20}{0.65}[/tex]
[tex]x=8[/tex]
Now,
Number of nickels = 8
Number of dimes = 8 + 10 = 18
Number of quarters = 2(8) = 16
Therefore, the number of nickels, dimes and quarters are 8, 18 and 16 respectively.
Please help me it would mean a lot
42.5 i think
The whole angle is 127 minus the angle we know (32) this leaves us with 85 for the rest of the angle but we still have to deal with the angle bisector so we divide it by 2 leaving us with 42.5 I'm pretty sure.

A number problem states, “–5 times a number, minus 22 gives a result of 23.” What is the number?
Answer:
im pretty sure its -9
Step-by-step explanation:
the equation explained would look something like this...
-5x-22=23
so you would isolate the variable by first adding 22 to both sides and the dividing by -5 on both sides
-5x-22=23
+22 +22
-5x/-5=45/-5
x=-9

Step-by-step explanation:
On the left, we have 7 -Xs and 7 1s. So, the left can be represented by the expression:
[tex]-7x+7[/tex]
On the right, we have 5 (positive) Xs and 16 1s. So, the right can be represented by the expression:
[tex]5x+16[/tex]
They are equal to each other. So:
[tex]-7x+7=5x+16[/tex]
Solve for x. Add 7x to both sides:
[tex]7=12x+16[/tex]
Subtract 16 from both sides:
[tex]-9=12x[/tex]
Divide both sides by 12:
[tex]x=-9/12[/tex]
Reduce:
[tex]x=-3/4[/tex]
So, our answer is C.

Which of the following types of numbers is irrational?
A.) a whole number
B.) fractions
C.) the number pi
D.) a decimal that terminates
Answer:
C
Step-by-step explanation:
the definition of an irrational number is an infinite decimal that has no repeating pattern. rational numbers can be converted into fractions.
A is incorrect because a whole number can be converted into a fraction.
ex: 1 is also 3/3
B is incorrect because the definition of a rational number is that it can be converted into a fraction.
D is incorrect because a terminating decimal can be made into a fraction.
ex: 4.5 is also 9/2
D)
Step-by-step explanation:A Irrational number is a decimal that terminates. I hope this helps! Please rate Brainiest!

I need help my mom is going to kill me
Answer:
x=8
m<FGH=32
m<HGI=32
m<FGI=64
Step-by-step explanation:
The first thing you're going to do is form an equation using 5x-8 and 6x-16. The reason for this is because the two angles FGH and HGI are congruent. You form an equation by setting the two equal to each other. LIke this:
5x-8=6x-16
Then you will find x which is 8. After you find x just plug in x for one of the equations like so:
5(8)-8=_ or 6(8)-16=_
You only need to plug in x for one of the angles because they are congruent so you will get the same answer.
To find the measurment of FGI you add the values from FGH and HGI together (32+32) and you'll get 64.

Answer:
7/10
Step-by-step explanation:
2/5 multiply the denominator by 2 which will make it 10. Then multiply the numerator by 2 which will make it 4. So it will be 4/10. Then add 4/10 to 3/0 which makes 7/10.
Write the nature of roots of the quadratic equation 9x^2 -6x+2
Answer:
roots are not real
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 (a ≠ 0 )
Then the nature of the roots can be found using the discriminant
Δ = b² - 4ac
• If b² - 4ac > 0 then roots are real and distinct
• If b² - 4ac = 0 then roots are real and equal
• If b² - 4ac < 0 then roots are not real
Given
9x² - 6x + 2 = 0
with a = 9, b = - 6, c = 2 , then
b² - 4ac = (- 6)² - (4× 9 × 2) = 36 - 72 = - 36
Since b² - 4ac < 0 then the roots are not real
Solve the system x+2z=30 y+z=12 z=1
Answer:
x=28 y=11 z=1
Step-by-step explanation:
plug in 1 for z in x+2z=30 to get x+2(1)=30. Then you should get x+2=30 which is x=28.
Then, plug 1 in for the second equation of y+z=12 so you get y+1=12. Then you should get y=11.

Step-by-step explanation:
You have at most $3.65 to make copies for a school project. Each copy costs $0.25. Write and solve an inequality that represents the number of copies you can make.
The equation for the problem is [tex]0.25x[/tex] ≤ [tex]3.65[/tex]
Hope it helps!
You can make the maximum number of copies would be 14.6 which is determined by the inequality 0.25x ≤ 3.65 where x represents the number of copies.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
You have at most $3.65 to make copies for a school project. Each copy costs $0.25 which is given in the question.
As per the given condition, the required inequality would be:
⇒ 0.25x ≤ 3.65
Here x represents the number of copies
⇒ 0.25x ≤ 3.65
Divided by 0.25 both sides of the inequality, and we get
⇒ x ≤ 3.65/0.25
⇒ x ≤ 14.6
Therefore, you can make the maximum number of copies would be 14.6.

A plumber earns $50 for a repair job, plus an additional $75 per hour he works. On Tuesday, he completed 3 repair jobs and earned a total of more than $600. Part A: Write an inequality that can be used to determine h, the number of hours the plumber worked Tuesday.
Answer:
[tex]150 + 75h > 600[/tex]
Step-by-step explanation:
The inequality that can be used to determine h is shown below:-
As per the given situation, it is mentioned that a plumber could earns $50 for a repair job, so for three jobs he earned $150 as a total amount
Now
We presume h be the number of hours
Also he earns additional $75 per hour worked so $75
Total amount is $150 + $75h)
The total amount is more than $600
So, the inequality equation is as given below:
[tex]150 + 75h > 600[/tex]
