Solve for x. Resuelve la x. 5 (4 + 2x) < 40
Step 1: Simplify both sides of the inequality.
10x+20<40
Step 2: Subtract 20 from both sides.
10x+20−20<40−20
10x<20
Step 3: Divide both sides by 10.
[tex]\frac{10x}{10}[/tex] < [tex]\frac{20}{10}[/tex]

Answer:
Step-by-step explanation:
A high school has 32 players on the football team. The summary of the players' weights is given in the box plot. Approximately, what is the percentage of players weighing greater than or equal to 233 pounds
Answer:
[tex]\% = 11.96\%[/tex]
Step-by-step explanation:
Given
See attachment for box plot
Required
Percentage greater than or equal to 233
From the box plot, the maximum is:
[tex]Max = 244[/tex]
The minimum is:
[tex]Min = 152[/tex]
Percentage greater than 233 is calculated as:
[tex]\% = \frac{Max - 233}{Max - Min}[/tex]
[tex]\% = \frac{244 - 233}{244-152}[/tex]
[tex]\% = \frac{11}{92}[/tex]
Express as percentage
[tex]\% = \frac{11}{92}*100\%[/tex]
[tex]\% = \frac{1100}{92}\%[/tex]
[tex]\% = 11.96\%[/tex]

2x+5y=20 y=-0.4x-1 i really need help over here
Answer:
x=6.25 and y=1.5
Step-by-step explanation:
Given equation
2x+5y=20
y=0.4x-1
Putting the value of y in above equation
2x+5(0.4x-1)=20
2x+2x-5=20
4x-5=20
4x=20+5
4x=25
x=6.25
Now,
y=0.4x-1( Given)
Putting the value of x=6.25 in above equation y
y=0.4(6.25)-1
y=2.5-1
y=1.5
If y varies directly as x, and y is 6 when x is 72, what is the value of y when x is 8?
1/9
2/3
54
96
Answer:
y = 2/3.
Step-by-step explanation:
y = constant nunber × x,
6 = constant number × 72,
Constant number is 1/12.
y = 1/12 × 8 = 2/3.
Thus the answer is 2/3.
A saleswoman sells a dried-fruit mixture for $5.60 per pound and nuts for $14.25 per pound. She wants to blend the two to get a 15-lb mixture that she will sell for $9.06 per pound. How much of each should she use? Solve using matrix
Answer:
Nuts= 2.56
Dried fruit= 12.44
Step-by-step explanation:
x + y = 15
5.6 x + 14.25 y = 9.06 * 15
~~~~~~~~~~~~~~~~~~~~~
x = 15 - y
5.6 x + 14.25 y = 134.9
~~~~~~~~~~~~~~~~~~~
5.6(15 - y) + 14.25 y = 134.9
84 -5.6y + 14.25y = 134.9
19.85y - 50.9
y = 2.56
x= 12.44

What is the circumference of a circle when the diameter is 3
Answer:
9.42 units (3 s.f.)
Step-by-step explanation:
Circumference of circle= 2πr
Radius
= diameter ÷2
= 3 ÷2
= 1.5
Circumference of circle
= 2(π)(1.5)
= 3π
= 9.42 units (3 s.f.)
Answer:
C=3π OR around 9.42478...
Step-by-step explanation:
If the diameter is 3, then the radius is 1.5
C=2πr
C=2π(1.5)
C=3π [You can also see that you could find the circumference by multiplying the diameter to pi because 2r is diameter.]
C= roughly 9.42478...
How do you solve a system of linear equations by graphing?
9514 1404 393
Explanation:
This is a self-answering question: you solve it by graphing the equations.
The solution is where the lines intersect. The point of intersection of the lines is the point that satisfies all the equations for the lines, hence is a solution to the system. If they do not intersect, there are no solutions. If the lines are coincident, there are an infinite number of solutions.
__
The equations can be graphed by any of a number of methods. (My favorite is to let a graphing calculator do it.) The method of choice depends on the coefficients and the form the equations are given in. Methods of graphing are a topic for a more lengthy discussion.

What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Here, we have,
The given equation is 13 - 2w = w + 6.
We need to solve the equation by squaring both sides of the equation.
Now, 13 - 2w = w + 6 squaring both sides of the equation.
That is, (13-2w)²= 169 - 52w + 4w²
(w+6)²= w²+ 12w + 36
Setting them equal, we get
169 - 52w + 4w² = w² + 12w + 36
⇒3w²- 64w + 133 = 0
Now, using the quadratic formula, we get
x = (64±√(64² - 4×3×133))/6
⇒x = (64±√2500)/6.
⇒x = (64±√50)/6.
⇒x = 19 or 14/6 = 7/3.
Solving the original equation, we get
7 = 3w⇒w = 7/3
Therefore, x = 19 is the extraneous solution Li Juan obtained.

What is the value of y?
Answer:
y=60°
Step-by-step explanation:
y+60+60=180 degree (sum of interior angles of a triangle)
y+120=180
y=180-120
y=60 degree
Answer:
Since AC=BC=AB
ABC TRIANGLE IS A EQUILATERAL TRIANGLE
Y+60+60 =180
Y =180-120
y = 60

an 18-foot wire is to be cut so that the longer piece is 5 times longer than the shorter piece. find the length of each peice
Answer:
The longer piece is 15 feet long and the shorter piece is 3 feet long.
Step-by-step explanation:
Create a system of equations where x is the length of the longer piece and y is the length of the shorter piece:
x + y = 18
x = 5y
Solve by substitution by substituting 5y as x into the first equation:
x + y = 18
5y + y = 18
Solve for y:
6y = 18
y = 3
So, the shorter piece is 3 feet long. Since the longer piece is 5 times longer, find its length by multiplying this by 5:
3(5)
= 15
So, the longer piece is 15 feet long.
The longer piece is 15 feet long and the shorter piece is 3 feet long.
Dan has an old lawn mower! It takes him 1 hour to mow the whole lawn. How many square yards does Dan cut in one minute? Hints: There are 60 minutes in 1 hour. To find the unit rate divide the area of the lawn by the amount of time it takes Dan to mow the whole lawn.
40 square yards per minute
400 square yards per minute
2400 square yards per minute
240 square yards per minute
Answer: You didnt mention how much Dan mows in 1 hour, but just do that divided by 60

If a1 = 4 and an = (an-1)^2 + 3 then find the value of a4.
9514 1404 393
Answer:
a4 = 132,499
Step-by-step explanation:
Use the recursive relation repeatedly.
a1 = 4
a2 = (a1)² +3 = 4² +3 = 19
a3 = 19² +3 = 364
a4 = 364² +3 = 132,499
