Answers
Answer: x=-2
Step-by-step explanation:
Given
-3x=-x+4
Add x on both sides
-3x+x=-x+4+x
-2x=4
Divide -2 on both sides
-2x/-2=4/-2
x=-2

Please let me know if you have any questions
Answer:
x = -2
Step-by-step explanation:
-3x = -x + 4
Add x to the left hand side to bring all like terms together.
-3x + x = 4
Combine like terms.
-2x = 4
Divide both sides by -2.
x = -2

50.7 is what percent of 32? Round to the nearest tenth.
Answers
Answer:156.25 or 156.3
Step 1: We make the assumption that 32 is 100% since it is our output value.
Step 2: We next represent the value we seek with x
Step 3:100%=32
Step 4:x%=50
Step 5:100%=32 x%=50(2)
Step 6:100%/x%=32/50
Step 7:x%/100=50/32 will give u 156.25% or round to the nearest tenth 156.3%
Answer:
56.3%
Step-by-step explanation:
0.5625×100= 56.25%
round to the nearest tenth.. which is 56.3%

What is the y-coordinate of the solution to the system of equations? 5x-y=25 4x+3y=1
Answers
Answer:
The y-coordinate of the solution is thus -5.
Step-by-step explanation:
Rewrite 5x-y=25 4x+3y=1
in a column:
5x-y=25
4x+3y=1
If we want to find the y-coordinate of the solution, we need to eliminate x. Solving the second equation for 4x yieds 4x = 1 - 3y, or
x = (1 - 3y)/4.
If this is inserted into 5x - y = 12, we get:
5(1 - 3y)/4 - y = 25, or (multiplying all terms by 4 to eliminate fractions):
5 - 15y - 4y = 100, or
-19y = 95, which yields y = -5
The y-coordinate of the solution is thus -5.
Which type of triangle has side measures of 5 cm, 9 cm, and 12.7 cm and one angle measure of 128°?
A.
acute isosceles
B.
obtuse scalene
C.
obtuse isosceles
D.
acute scalene
Answers
This question is dealing with classification of triangles based on angles or on number of equal sides.
the triangle is called an Obtuse Scalene Triangle
Now, the classification in terms of angles are;
- Acute angle is when the angle measures between 0 and 90 degrees.
- Obtuse angle is when the angle is greater than 90 but less than 180 degrees.
- right angle is when the angle is exactly 90 degrees.
- Reflex angle is when the angle is greater than 180 but less than 360 degrees.
Now the classification in terms of equal sides;
- Isosceles triangle is one that has 2 equal sides.
- Equilateral triangle is one that has 3 equal sides.
- Scalene triangle is one that has no equal sides.
The lengths of the three sides of the triangle given are;
5 cm, 9 cm, and 12.7 cm
The three sides are not equal and from definition above it is called scalene triangle.
The angle given is 128° and from definition earlier, it is an obtuse angle.
In conclusion, the triangle is called an Obtuse Scalene Triangle

Alguien que me ayude a calcular la medida de un angulo central interno y externo de un heptagono { interno y externo]
Answers
Responder:
suma de ángulos interiores = 900 °
Suma de ángulos exteriores = 360 °
Explicación paso a paso:
Un heptágono es un polígono de 7 lados:
Para cualquier polígono con n lados:
El ángulo exterior del polígono suma 360 °
Por lo tanto, la medida de cada ángulo central de un heptágono es:
Suma de ángulos exteriores / número de lados
360 ° ÷ 7
= 51,43 °
El ángulo interior de un polígono se obtiene mediante la relación:
(n - 2) 180 °
Heptágono tiene 7 lados:
(7 - 2) 180 °
5 (180 °)
= 900 °
Por tanto, suma de ángulos interiores = 900 °
Suma de ángulos exteriores = 360 °

Answer: m∠5 = 75°.
Step-by-step explanation:
We know that lines A and B are parallel, and angles 1 and 5 are formed by the same line intersecting the parallel lines.
We know that:
"When a line intersects two parallel lines, corresponding angles are formed, such that we could think on four quadrants, the angles in each quadrant are equivalent between them"
Well, here we can see that angle ∠1 and angle ∠5 are formed by the same line, and both are in the same quadrant (would be the third quadrant if we use standard notation)
Then the measure of ∠1 is the same as the measure of ∠5
And we know that m∠1 = 75°
Then we must have that m∠5 = 75°.
The amount of money in a bank account increased by 17.5 % 17.5% over one year. If the amount of money at the beginning of the year is represented by A A, which expression below represents the amount of money in the bank account after the increase?
Answers
Answer: 1.175A
Step-by-step explanation:
From the information given in the question, we are told that the amount of money that is in a bank account increased by 17.5% while the money at the beginning of the year is represented by A.
The expression that represents the amount of money in the bank account after the increase will be:
= A + (17.5% × A)
= A + (17.5/100 × A)
= A + (0.175 × A)
= A + 0.175A
= 1.175A

does a bag of chips cost?
S
Answers
Answer:
Step-by-step explanation:
5h + c = 8.50
2h + 3c = 6
Multiply first equation by -3, then add it to second equation.
-15h - 3c = -25.50
2h + 3c = 6
------------------------
-13h = -19.50
h = -19.50/(-13) = 1.5
c = 8.50-5h = 1'
hot dog costs $1.50
chips cost $1
If you add Natalie's age and Fred's age, the result is 46. If you add Fred's age to 4 times Natalie's age, the result is 91. Write and solve a system of equations to find how old Fred and Natalie are.
Answers
Answer:
Fred = 31
Natalie = 15
Step-by-step explanation:
We have Natalie and Fred's whos age are unknown, we know that when added, their ages equal 46. While when multiplied with Natalie's age 4 times, their ages is 91.
Create two systems :
F = Fred
N = Natalie
F + N = 46
4N + F = 91
We can change the first equation to Natalie's age alone :
N = 46 - F
Now substitute this into the second equation :
4(46 - F) + F = 91
Distribute :
184 - 4F + F = 91
Subtract 184 from both sides :
-4F + F = -93
Add like terms :
-3F = -93
Divide -3 from both sides :
F = 31
Therefore, Fred is 31 years old. Now replace his age in the first equation :
31 + N = 46
46 - 31
15
Therefore, Natalie is 15 years old.

A bank loans a customer $100,000 for a period of 2 years. The simple interest rate of the loan is 5.7%. What is the total amount that the customer will need to pay the bank over the 2 years?
Answers
Answer:
$111400
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5.7%/100 = 0.057 per year,
then, solving our equation
I = 100000 × 0.057 × 2 = 11400
I = $ 11,400.00
The simple interest accumulated
on a principal of $ 100,000.00
at a rate of 5.7% per year
for 2 years is $ 11,400.00.
