A washer and dryer cost $711 combined the washer cost $61 more than the dryer what is the cost of the dryer
Answer:
$325
Step-by-step explanation:
Let the dryer be x and the washer be y
x+y= 711---------1
y= x+61-----------2
put y= x+61 in 1
x+x+61= 711
2x+61= 711
2x= 711-61
2x=650
x= 650/2
x=325
Hence the dryer cost $325
Marty's class collected $34.00 in a school-wide penny collection contest. If Tommy's class added $3.00 to the amount they

What is the solution for an equation?The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of that variable would give a true mathematical statement.
We need to find the solutions of the equation 2(x + $3.00)= $34.00 ;
Now solving for x;
2(x + $3.00)= $34.00
Open the bracket;
2x + 6 = 34
Combine the like terms;
2x = 34 - 6
2x = 28
x = 14
Therefore, the equation 2(x + $3.00)= $34.00 has only one solution which is 14.

3x+16=7x
answer please
Answer:
x = 4
Step-by-step explanation:
We have the algebraic expression 3x + 16 = 7x and are asked to solve.
When we need to solve for x, we need to get x alone always.
So 3x + 16 = 7x.
Subtract 3x from both sides :
16 = 4x
Divide 4 from both sides :
x = 4
Answer:
[tex] \large \boxed{x = 4}[/tex]
Step-by-step explanation:
Goal
Solve for x-term.Given
Equation[tex]3x + 16 = 7x[/tex]
Step 1
Combine like terms. We move 3x to subtract 7x since we can't add with a constant with a variable.[tex]16 = 7x - 3x \\ 16 = 4x[/tex]
Step 2
Move 4 to divide 16 because we need to make x-term as the subject of equation.[tex] \frac{16}{4} = x \\ 4 = x[/tex]
Step 3
If you are not sure that the answer is correct, we can check the answer by substituting x = 4 in the equation.[tex]3x + 16 = 7x \longrightarrow 3(4) + 16 = 7(4) \\ 12 + 16 = 28 \\ 28 = 28[/tex]
The equation is true for x = 4. Hence, the solution is x = 4
Solve for x. Round to two decimal places if necessary.
Answer:
Length of JK is 68.27 units.
Step-by-step explanation:
By applying geometric mean theorem (leg theorem) in the triangle attached,
[tex]\frac{KL}{KM}= \frac{JK}{KL}[/tex]
(KL)² = (KM)(JK)
(32)² = (15)(x)
x = [tex]\frac{1024}{15}[/tex]
x = 68.2666
x ≈ 68.27
Therefore, length of JK is 68.27 units.

the line with a slope of 1/3 and a y- intercept of - 15 intersects the line passing through which of these pairs of points?
Answer:
Options (C), (D) and (E)
Step-by-step explanation:
Slope of the given line = [tex]\frac{1}{3}[/tex]
Any line having same slope will be parallel to the given line otherwise the lines will intersect.
Therefore, we will find the slope of the lines passing through two points given in the options.
Option A
Slope of the line passing through (12, -13) and (15, -12)
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{-13+12}{12-15}[/tex]
= [tex]\frac{1}{3}[/tex]
Therefore, both the lines are parallel having no point of intersection.
Option B
Slope = [tex]\frac{-9+7}{18-24}[/tex]
= [tex]\frac{1}{3}[/tex]
Both the lines are parallel having no point of intersection.
Option C
Slope = [tex]\frac{-20+21}{15-18}[/tex]
= [tex]-\frac{1}{3}[/tex]
Therefore, both the lines will intersect.
Option D
Slope = [tex]\frac{-15+14}{30-36}[/tex]
= [tex]\frac{1}{6}[/tex]
Both the lines will intersect each other.
Option E
Slope = [tex]\frac{-11+10}{24-30}[/tex]
= [tex]\frac{1}{6}[/tex]
Both the lines will intersect each other at a point.
Options (C), (D) and (E) are the correct options.

2400 people attended a basketball game. 696 of the people attending supported the home team, while 1704 supported the visiting team. What percentage of people attending supported the home team?
Answer:
0.29 or 29 percent I put it on god
Step-by-step explanation:
The percentage of people attending supported the home team is 29%.
What is percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
Given, 2400 people attended a basketball game. 696 of the people attending supported the home team, while 1704 supported the visiting team.
From the general formula of percentage:
percentage = value/ total value * 100
Since, Out of 2400 only 696 supported the home team
thus,
Percentage = 696/2400*100
Percentage = 29%
Therefore, 29% percentage of people attending supported the home team.

Given:
A figure in which a transversal line intersect two parallel lines.
[tex]m\angle 2=4x+7, m\angle 7=5x-13, m\angle 5=68[/tex] and [tex]m\angle 3=3y-2[/tex].
To find:
The value of x and y.
Solution:
We know that, if a transversal line intersect two parallel lines, then
(1) Alternate exterior angles are equal.
(2) Same sided interior angles are supplementary. So their sum is 180 degrees.
In the given figure j and k are parallel lines and l is a transversal line.
From the given figure, it is clear that,
[tex]m\angle 2=m\angle 7[/tex] (Alternate exterior angles are equal)
[tex]4x+7=5x-13[/tex]
[tex]7+13=5x-4x[/tex]
[tex]20=x[/tex]
Therefore, the value of x is 20.
Now,
[tex]\angle 3+\angle 5=180[/tex] (Same sided interior angles are supplementary)
[tex]3y-2+68=180[/tex]
[tex]3y+66=180[/tex]
[tex]3y=180-66[/tex]
[tex]y=\dfrac{180-66}{3}[/tex]
[tex]y=\dfrac{114}{3}[/tex]
[tex]y=38[/tex]
Therefore, the value of y is 38.

Answer:
s=6
Step-by-step explanation:
Hope this helps :)
The value of s for the given expression 3(s + 4 = 30 will be 6.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
A statement expressing the equality of two mathematical expressions is known as an equation.
As per the given expression,
3(s + 4) = 30
Divide both sides by 3
s + 4 = 10
Subtract both sides by 4
s + 4 - 4 = 10 - 4
s = 6
Hence "The value of s for the given expression 3(s + 4 = 30 will be 6".
