x/r - s = t
Add s to both sides.
x/r - s + s = s + t
x/r + 0 = s + t
x/r = s + t
Multiply both sides by r.
r(x/r) = r(s + t)
x = r(s + t)
Understand?
Answer:
x=tr/s
Step-by-step explanation:
x/r-s=t
x-s=t×r
x-s/s=tr/s
x=tr/s
Hi! I need help with my hw! Repost since people could not see it.
As you can see from the rate of change, 1=16 and 0=0. You can tell by subtracting 48-32 and that'll give you the rate of change which is equivalent go 16. After 6 days, you'll get 96 dollars. I figured that out by adding the rate of change to 80 and that gave me the answer of 96.
The idea of a rule that assigns outputs to inputs is very abstract. These rules often come in the
form of tables, but can also come in the form of equations, graphs, and ordered pairs.
Exercise #2: In the function below, the variable y is a function of the variable x:
y = x2 +10
Give the outputs for each of the following inputs. Show how you found your answers.
(a) x = 3
(b) x = -5
(c) x = 0
y = 5x - 3
What is 62400 millimeters in meters?
state your solution
Answer:
62.4 meters
Step-by-step explanation:
1 millimeters to 0.001 meters
62400 * 0.001 = 62.4
Answer:
0.624m
Step-by-step explanation:
62400mm in cm is 62.4cm
there is 100cm in a meter so you don't have a total of 1m
therefore you divide it by 100 after you convert to cm
f f(x) = 10-2x and g(x) = 6x - 5, then (f+g) (x) = ?
Answer:
(f+g)(x)=4x+5
Step-by-step explanation:
Just add the two functions together:
(f+g)(x)=f(x)+g(x)=(10-2x)+(6x-5)=-2x+6x+10-5=4x+5
So (f+g)(x)=4x+5

By vertical angle theorem
110°
х
z
у
Find the unknown angle measures
Answer:
x = z = 70°
y = 110°
Step-by-step explanation:
From the diagram, we have 4 angles;
To find y;
110° and y are vertically opposite angles so they are equal.
So, y = 110°
Also, y and x lie on a straight line. Sum of angles on a straight line is 180°;
y + x = 180
110 + x = 180
x = 180-110 = 70°
Also, x and z are vertically opposite angles and they are equal;
x = z = 70°
y = 110°
Evan and Carter are making chocolate milk which mixes milk with chocolate syrup. Evan's recipe calls for 5 cups of milk for every 4 teaspoons of chocolate syrup. Carter's recipe needs 3 cups of milk for every 2 teaspoons of chocolate syrup. Whose recipe has the stronger tasting chocolate milk?
Answer:
Evan's recipe
Step-by-step explanation:
Given that:
Evan's recipe :
5 cups of milk for every 4 teaspoons of chocolate syrup
Carter's recipe:
3 cups of milk for every 2 teaspoons of chocolate syrup.
Recipe with the stronger tasting chocolate milk:
Take the ratio of cups of milk to teaspoons of chocolate syrup:
Evan's :
5 / 4 = 1.25
Carter's :
3 /2 = 1.5
Evan's recipe has the stronger tasting chocolate milk recipe :
5 milk cup = 4 chocolate spoons
Number of chocolate milks for 3 milk cups = x in Evan's recipe
5 = 4
3 = x
5x = 12
x = 12/5
x = 2.4 teaspoons
This is 2.4 spoons compared Carter's recipe which uses 2 spoons for every 3 milk cups

Answer:
Step-by-step explanation:
1. 3(5) plus 2 = 17
2. 2(5)^2 = 25(2) = 50
3. (5-2)^2 =3^2 = 9
X=5
y=2
then a: 3*5+2=17
b:2*5*5=50
c:5-2=3*3=9
a=17
b=50
c=9

A storage box has a volume of 56 cubic feet and the base of the box is 4 by 1/2 feet what is the height of the box?
Answer:
h = 28Step-by-step explanation:
volume of box = 56 ft³
base = 4
width = 1/2
height = ?
volume = base x width x height
56 = 4 x 0.5 x h
56 = 2h
h = 56 / 2
h = 28
therefore, the height of the box is 28 ft

10 – 5y = 2(14-y)
solve. show ur work
Answer:
The answer is y= −6
Step-by-step explanation:
Let's solve your equation step-by-step.
10−5y=2(14−y)
Step 1: Simplify both sides of the equation.
10−5y=2(14−y)
10+−5y=(2)(14)+(2)(−y)(Distribute)
10+−5y=28+−2y
−5y+10=−2y+28
Step 2: Add 2y to both sides.
−5y+10+2y=−2y+28+2y
−3y+10=28
Step 3: Subtract 10 from both sides.
−3y+10−10=28−10
−3y=18
Step 4: Divide both sides by -3.
−3y/−3=18/−3
y=−6
Answer:
y=−6
Answer:
y= -6
Step-by-step explanation:
10-5y=2(14-y)
10-5y=28-2y
10-5y+2y=28
-3y=28-10
-3y=18
y= -6

PLEASE HELP, 6TH GRADE MATH a chemist is raising the temperature of a liquid the temperature is now 8.4 degrees celsius and is increasing by 1.6 degrees celsius per minute. How many minutes will it take for the temperature to reach 0 degrees celsius?
Complete question :
A chemist is raising the temperature of a liquid. The temperature is now --8.4 degrees Celsius and is increasing by 1.6 degrees Celsius per minute. How many minutes will it take it for it to take to get to 0 degrees Celsius
Answer:
5.25 minutes
Step-by-step explanation:
Given that :
Current temperature = - 8.4°C
Rate of change = 1.6°C per minute
For the temperature to be 0°C ; it will take
(Final temperature - current temperature) rate of change
(0°C - (-8.4°C)) / 1.6°C
(0°C + 8.4°C) / 1.6°C
8.4°C / 1.6°C
= 5.25 minutes

X =2
Step-by-step explanation:
In answer
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
[tex]3x+1= 7[/tex]
[tex]3x = 6\\ \[/tex] Subtract both sides by 1.
[tex]\frac{3x}{3} = \frac{6}{3}[/tex] Divide both sides by the coefficient.

Are the triangles congruent? If so, which of the 5 ways to prove triangles congruent could you use?
We can prove that these triangles are congruent by using SAS congruency rule.
SAS which means Side Angle Side.
In these triangles, we see that two sides are equal in length and one angle is equal.
So, SAS congruency rule is the answer.
