Answer:
p : q = 3 : 2
Step-by-step explanation:
You are given sufficient information to write two relations involving p and q. We presume these will be sufficient to find an answer to the question. We will be able to find p and q. Then we can find their ratio, as the problem asks.
(p-15)/(q-15) = 2/1
(p+30)/(q+30) = 5/4
__
From the first equation, we get ...
p -15 = 2(q -15)
p = 2q -15 . . . . . . . add 15, simplify
From the second equation, we get ...
4(p +30) = 5(q +30)
4p + 120 = 5q + 150
4p = 5q + 30
Using the first equation to substitute for p, we have ...
4(2q -15) = 5q +30
8q -60 = 5q +30 . . . eliminate parentheses
3q = 90 . . . . . . . . . . . add 60-5q to both sides
q = 30 . . . . . . . . . . . . divide by 3
p = 2q -15 = 2(30) -15 = 45
Then the desired ratio is ...
p : q = 45 : 30
p : q = 3 : 2

Lorenzo ate 25 of his bag of almonds. His 4 friends ate equal shares of the remaining bag of almonds. Which expression represents the almonds that each friend ate?
Answer:
(x - 25) / 4
Step-by-step explanation:
In this scenario, we have one unknown variable which is the total of the bag of almonds, therefore we can represent this with the variable x. Since Lorenzo ate 25 of this bag we would need to subtract this from the total of the bag. Then we need to divide the remainder by 4 since each of his friends ate the rest in equal parts. This would leave us with the following expression ...
(x - 25) / 4

the length of a boat is 10.8 m Boris buys a scale model of the boat the scale of the model is 1 to 18 work out the length of the scale model of the boat give your answer in centimetres
Answer:
The size of the scale model is 60 centimeters.
Step-by-step explanation:
Given that the length of a boat is 10.8 m, and Boris buys a scale model of the boat whose ratio is 1 to 18, to determine the length of the scale model of the boat in centimeters the following calculation must be performed:
1m = 100cm
10.8 m = (10.8 x 100) = 1080 cm
1080/18 = X
60 = X
Therefore, the size of the scale model is 60 centimeters.

Solve the equation. Type just the numeral answer. Do NOT round your solution.
-5=b-2.3
b=
Answer:
The value of b = -2.7
Step-by-step explanation:
Given
As the equation is given by
[tex]-5=b-2.3[/tex]
To determine
Solve the equation for b
Given the equation
[tex]-5=b-2.3[/tex]
switch the sides
[tex]b-2.3=-5[/tex]
Add 2.3 to both sides
[tex]b-2.3+2.3=-5+2.3[/tex]
Simplify
[tex]b=-2.7[/tex]
Therefore, the value of b = -2.7
Answer:
b = -2.7

11g − 5g + –17g − –7g = –12
Answer:
g=3
Step-by-step explanation:
11g-5g+-17g-(-7g)=-12
Add the like terms (nice that in this case they are all on the same side)
6g+-17g-(-7g)=-12
-11g-(-7g)=-12
-4g=-12 Now we divide (phew that was a lot of negatives XD)
g=3

Answer:
The average depth of five lakes is 229m. If none of the lakes is less than 194m deep then the greatest possible depth of one of these lakes in meters is,
Answer:
369
Step-by-step explanation:
* = Multiply
5*229=1145
Lakes * Average = Total Average Depth of Five Lakes
(1145-369)/4=194 (it worked)
4 is the other lakes, 369 would be considered the largest lake.
Answer is 369.

You can work a total of no more than 15 hours each week at your two jobs. Housecleaning pays $8 per hour and your sales job pays $10 per hour.
You need to earn at least $130 each week to pay your bills.
Write a system of inequalities to represent this situation. DO NOT SOLVE.
Let x = # of hours housecleaning and y = # of hours at the sales job
use substitution to solve the system of equations. Write the solution as an ordered pair.
x + 2y = 14
y = 3x - 14
Answer:
Step-by-step explanation:
x + 2(3x - 14) = 14
x + 6x - 28 = 14
7x - 28 = 14
7x = 42
x = 6
y = 3(6) - 14
y = 18 - 14
y = 4

which property justifies step 3 Given: 4(x - 6) + 12 = 20
Answer:
x=8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4(x−6)+12=20
(4)(x)+(4)(−6)+12=20(Distribute)
4x+−24+12=20
(4x)+(−24+12)=20(Combine Like Terms)
4x+−12=20
4x−12=20
Step 2: Add 12 to both sides.
4x−12+12=20+12
4x=32
Step 3: Divide both sides by 4.
4x

Find the slope of the line that
passes through the following
points. (-5, -10), (-5, 15)
system of equations
Answer:1:(2,7)
2:i or (1,-3)
3:is c or (-15,-25)
Step-by-step explanation:like if this helped mark me brainlest please
Answer:
(2,7)
(1,-3)
(-15,-25)
Step-by-step explanation:
Because both equations are equal to the same thing (y) we can just set them equal to each other and solve for x
4x-1=2x+3
solve for x
4x=2x+4
2x=4
x=2
We know that x=2 and can plug this value in for x into any of the beginning equations
4(2)-1=y
7=y
The answer is (2,7)
2.) We can do the exact same process as question one
x-4= -3x
-4= -4x
x=1
plug this x value in into any of the starting equations
1-4=y
-3=y
The answer is (1,-3)
3.) Same deal as the other two
x-10=2x+5
-x=15
x= -15
Plug this value in for x into any beginning equation
2(-15)+5
-30+5
y= -25
(-15,-25)
