Step-by-step explanation:
Ratio Question:
The ratio of the money spent is 19/14. So you can create this equation:
19/14=38/x
Since they are the same ratio, this means that 38/x would equal 19/14.
Multiply both sides by 14 and x:
19x=532
532/19=x
x=28

y=x-3
-4x + y = -9
-x +y = -3 //-1
-4x + y = -9
x - y = 3

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
y = 4x - 9
y = x - 3
Step 2: Solve for x
Substitute in y: 4x - 9 = x - 3Subtract x on both sides: 3x - 9 = -3Add 9 to both sides: 3x = 6Divide 3 on both sides: x = 2Step 3: Solve for y
Define: y = x - 3Substitute in x: y = 2 - 3Subtract: y = -1The Jones family is building a circular swimming pool. If the radius of the pool is 14 feet, what is its circumference? Use π = 3.14 to solve.
Answer:
87.96 ft
Step-by-step explanation:
In order to find the circumference given the radius we use 2 pi r so it would be 2xpix14 which comes out to be 87.96
james went out for a long walk . He walked 3 2/5 of the mile. then he sat down to take rest . After that he walked 5/7 of a mile. how far did he walk together
Answer:
Altogether James walked [tex]4\frac{4}{35}[/tex] miles.
Step-by-step explanation:
The question involves mixed fractions. Mixed fractions are first converted into proper fractions and then any operation can be performed on them.
Given
Distance of first walk = [tex]3\frac{2}{5}[/tex] of a mile
Distance of second walk = 5/7
In order to find how much he walked altogether, we have to find the sum of both fractions.
[tex]Total\ distance = 3\frac{2}{5}+\frac{5}{7}\\= \frac{17}{5}+\frac{5}{7}\\=\frac{17*7}{5*7} + \frac{5*5}{7*5}\\=\frac{119}{35} + \frac{25}{35}\\=\frac{119+25}{35}\\=\frac{144}{35}\\=4\frac{4}{35}[/tex]
Hence,
Altogether James walked [tex]4\frac{4}{35}[/tex] miles.

Divide Rational Expressions
In the following exercises, divide.
Answer:
[tex]\displaystyle \mathbf{\frac{5}{(c+4)}}[/tex]
Step-by-step explanation:
Division of Rational Expressions
When dividing two rational expressions like f(c) / g(c), it's usually easier to multiply the numerator by the reciprocal of the denominator: f(c) * (1/g(c)). The reciprocal is just flipping the numerator and the denominator.
Let's find the following division:
[tex]\displaystyle \frac{\frac{c^2-64}{3c^2+26c+16}} {\frac{c^2-4c-32}{15c+10}}[/tex]
First, we factor the polynomials where possible.
[tex]c^2-64 = (c-8)(c+8)[/tex]
[tex]3c^2+26c+16=(3c+2)(c+8)[/tex]
[tex]c^2-4c-32=(c-8)(c+4)[/tex]
[tex]15c+10=5(3c+2)[/tex]
Substituting:
[tex]\displaystyle \frac{\frac{c^2-64}{3c^2+26c+16}} {\frac{c^2-4c-32}{15c+10}}=\frac{\frac{(c-8)(c+8)}{(3c+2)(c+8)}} {\frac{(c-8)(c+4)}{5(3c+2)}}[/tex]
Multiplying by the reciprocal of the denominator:
[tex]\displaystyle \frac{\frac{c^2-64}{3c^2+26c+16}} {\frac{c^2-4c-32}{15c+10}}=\frac{(c-8)(c+8)}{(3c+2)(c+8)}\cdot \frac{5(3c+2)}{(c-8)(c+4)}[/tex]
Simplifying by (c+8)(3c+2)(c-8):
[tex]\displaystyle \frac{\frac{c^2-64}{3c^2+26c+16}} {\frac{c^2-4c-32}{15c+10}}=\frac{5}{(c+4)}[/tex]
Answer:
[tex]\displaystyle \mathbf{\mathbf{\frac{5}{(c+4)}}}[/tex]
A mini bus can carry 8 students. How many mini buses will be needed to transport 38 students?
Answer:
5 buses
Step-by-step explanation:
you need to divide the number of students (38) by the number of students a mini bus can carry.
38 : 8 = 4.75
since they want to know how many buses will be needed to transport all students, you round 4.75 to 5

An airplane flying with the wind takes 2 hours to travel a distance of 360 miles.
The return trip takes 3 hours flying against the wind.
What is the speed of the airplane in still air and how fast is the wind blowing?
Answer: still air is 150mph. The wind speed is 30mph.
Step-by-step explanation:
X=speed of the plane, Y=speed of the wind.
360/2hours=180
360/3hours=120
2x=180+120
2x=300
X=150
The airplane in still air is 150mph
Add together
X+y=180
150+y=180
Y=180-150
Y=30mph
The wind speed is 30mph

Write an equation for the line that passes through (- 3, 5) and is parallel to y = - 6x + 1.
Answer:
y-5 = -6(x+3) OR y = -6x-13
Step-by-step explanation:
Let's use slope-intercept form to solve this problem.
Slope intercept form is the following:
y-y1 = m(x-x1)
x1 and y1 are given by the point in the problem.
x1 = -3, y1 = 5.
m is given by the equation in the problem. Lines that are parallel have the same slope. Thus,
m = -6.
If we plug these values into the equation for slope intercept form, we get the following:
y-5 = -6(x-(-3)) which becomes y-5 = -6(x+3)
This is an acceptable answer to the problem. However, point-slope form is also a way it can be written.
y-5 = -6x-18
y = -6x-13
