Answer:
x = 3/2y
y = 2/3x
Step-by-step explanation:
x = 3/2y
Swap sides so that all variable terms are on the left hand side
2x + 15 = 3y + 15
Subtract 15 from both sides
2x = 3y + 15 - 15
Subtract 15 from 15 to get 0
2x = 3y
Divide both sides by 2
2x/2= 3y/2
Dividing by 2 undoes the multiplication by 2
X = 3y/2
Y = 2/3x
Subtract 15 from both sides
3y = 2x + 15 - 15
Subtract 15 from 15 to get 0
3y = 2x
Divide both sides by 3
3/3y = 2/3x
Dividing by 3 undoes the multiplication by 3
y = 2/3x

A recipe for biscuits says to mix 6 cups of flour with 2 cups of milk.
How many cups of milk would you need for 5 cups of flour?
Answer:
[tex]\frac{5}{3}[/tex] or [tex]1\frac{2}{3}[/tex] cups of milk
Step-by-step explanation:
So if you have the ratio of 6 cups of flour to 2 cups of milk you can make this the fraction: [tex]\frac{6}{2}[/tex] and then for the 5 cups of flour to 'x' cups of milk the fraction would be: [tex]\frac{5}{x}[/tex]
To solve for 'x', let the 2 fractions equal each other and cross multiply.
[tex]\frac{6}{2} = \frac{5}{x}[/tex]
[tex]x = \frac{2*5}{6} = \frac{10}{6} = \frac{5}{3} = 1\frac{2}{3}[/tex]
So you would need [tex]\frac{5}{3}[/tex] or 1 and [tex]\frac{2}{3}[/tex] cups of milk for 5 cups of flour.

The volume of a rectangular solid is 540 cubic feet.
The width is 3 feet more than the height, and the
length is 4 more feet than the height. Find the
dimensions of the solid.
Answer:
l = 32.57, w = 24.43, h = 8.14
Step-by-step explanation:
volume = l*w*h
l = 4x
w = 3x
h = x
540 = 4x * 3x * x
540 = 12x^3
[tex]\sqrt[3]{540}[/tex] = 8.14
l = 4x = 4(8.14) = 32.57
w = 3x = 3(8.14) = 24.43
h = x = 8.14

Answer:
[tex]y=55\\x=108[/tex]
Step-by-step explanation:
We know that the total angle sum of the quadrilateral internal angles is 360° since we are working with a quadrilateral polygon.
So when finding the interior angles we set up the equation of
[tex]125+y=180\\72+x=180[/tex]
Subtract 180 by 125 and 72 to find y and x

geometry problem, Write the equation of each line described below,
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
(a)
y = - 2x + 5 ← is in slope- intercept form
with slope m = - 2
Parallel lines have equal slopes , then
y = - 2x + c ← is the partial equation
To find c substitute (- 3, 2 ) into the partial equation
2 = 6 + c ⇒ c = 2 - 6 = - 4
y = - 2x - 4 ← equation of parallel line
----------------------------------------------------------
(b)
y = 3x + 4 ← is in slope- intercept form
with slope m = 3
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{3}[/tex] , then
y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c substitute (3, 2 ) into the partial equation
2 = - 1 + c ⇒ c = 2 + 1 = 3
y = - [tex]\frac{1}{3}[/tex] x + 3 ← equation of perpendicular line

sweaters were on sale for 35% off the regular price. If the regular price for a sweater was $65.00, what was the sale price?
help pls again
Answer:
$42.25
Step-by-step explanation:
List price = $65.00
Discount = 35% .
Hence the new price is (100-35)% = 65% of original price .
=> price = $ 65 * 65/100
=> price = $42.25

Help!! Irrelevant / Random answers will be reported*
Answer:
[tex]m = - \frac{1}{4} [/tex]
[tex]c = 2 \frac{3}{4} [/tex]
Step-by-step explanation:
Let's start by finding the point of intersection of the lines x -2y= -1 and y= 2.
x -2y= -1 -----(1)
y= 2 -----(2)
Substitute (2) into (1):
x -2(2)= -1
x -4= -1
x= 4 -1
x= 3
Thus, the point of intersection is (3, 2).
y= 4x +8
Slope= 4
The product of the slopes of perpendicular lines is -1.
4m= -1
m= -¼
y= -¼x +c
Since the line passes through (3, 2), we can substitute this coordinates into the equation to find the value of c.
When x= 3, y= 2,
[tex]2 = - \frac{1}{4} (3) + c[/tex]
[tex]c = 2 + \frac{3}{4} [/tex]
[tex]c = 2 \frac{3}{4} [/tex]

solve the following inequality
-2x+12<36
Answer:
x>-12
Step-by-step explanation: you have the equation -2x+12 <36
so what do you do first?
you would subtract 36 on both sides like this: -2x+12-36 <-36
then you get -2x < 24
divide both sides by -2 like this : -2/-2x<24/-2
and since your dividing by -2 on both sides
the sign would be less then sign instend of a greater then
so the answer is x>-12

The time it will take them to finish the journey is 2.6 hours
What is speed?Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered.
It is measured in meter/sec(SI unit). it can also be measured in other units.
Speed is expressed as;
speed = distance /time
distance = 37.7 miles
speed = 14.5 miles per hour
time = distance /speed
= 37.7/14.5
= 2.6 hours.
Therefore it will take them 2.6 hours to finish the journey.
