Answer:
r = t + q - s
Step-by-step explanation:
t = r - q + s
goal is to isolate the variable
add q to both sides (this cancels the q out on the right side)
t + q = r - q + q + s
t + q = r + s
subtract s from both sides
t + q - s = r + s - s
t + q - s = r
In other words:
r = t + q - s
What is the inverse of the function f(x) = 2x – 10?
Answer:
f^-1(x) = (x+10) / 2
Step-by-step explanation:
sooo
f(x) = 2x - 10
y = 2x - 10
x = 2y - 10
x + 10 = 2y
y = (x + 10) / 2
f^-1(x) = (x+10) / 2
Answer:
[tex]f^{-1}(x)=\frac{x+10}{2}[/tex]
Step-by-step explanation:
[tex]f(x)=2x-10\\\\y=2x-10\\\\x=2y-10\\\\x+10=2y\\\\\frac{x+10}{2}=y\\ \\f^{-1}(x)=\frac{x+10}{2}[/tex]
As the two functions are inverses of each other, they will be symmetrical about the line [tex]y=x[/tex].

Can someone explain how to get the answer to this question please.
Answer:
m∠2 is 55°
Step-by-step explanation:
Let us revise some facts in geometry
In any triangle, the sum of the measures of its angles is 180°If two line intersected at a point, then they formed two pairs of vertically opposite angles, the vertically opposite angles are equal in measuresWe will use these facts to solve our question
∵ ∠1 is an angle of a triangle
∴ m∠1 + 40° + 85° = 180° ⇒ 1st fact
→ Add the like terms in the left side
∴ m∠1 + 125° = 180°
→ Subtract 125° from both sides
∴ m∠1 + 125° - 125° = 180° - 125°
∴ m∠1 = 55°
∵ ∠1 and ∠2 formed from the intersecting of two lines
∴ ∠1 and ∠2 are vertically opposite angles
∴ m∠1 = m∠2 ⇒ 2nd fact
∵ m∠1 = 55°
∴ m∠2 = 55°
Which step shows the result of applying the subtraction property of equality?

what is the measure of 6?
explain why please
please anwser this asap.
Statement Reason
1. 3x + 7 = ∠2 (Vertically opposite angles)2. ∠2 = ∠5 (Corresponging angles)3. ∠5 = ∠6 (Vertically opposite angles)⇒ ∠2 = ∠5 = ∠6 = 3x + 7
Looking at the picture, we can see that ∠6 and 4x + 5 are a linear pair.
Finding the value of x:
⇒ ∠6 + 4x + 5 = 180
⇒ 3x + 7 + 4x + 5 = 180
⇒ 7x + 12 = 180
⇒ 7x = 180 - 12
⇒ 7x = 168
⇒ 7x/7 = 168/7
⇒ x = 168/7 = 24
Now, substitute the value of x into the expression "3x + 7" to find ∠6.
Finding the measure of ∠6:
⇒ ∠6 = 3x + 7
⇒ ∠6 = 3(24) + 7
⇒ ∠6 = 72 + 7
⇒ ∠6 = 79°

Ana angle measure 79.8 degrees less than the measure of it’s complementary angle what is the measure of each angle
Answer:
x = 129.8 degrees, y = 50.2 degrees, x + y = 180
Step-by-step explanation:
Let's say you have 2 supplementary angles, x and y
So x + y = 180
if x is 79.8 degrees less than the measure of a supplementary angle, then x = y - 79.8
Putting this into our x + y = 180 equation, we get
(y - 79.8) + y = 180
2y - 79.8 = 180
2y = 180 + 79.8
2y = 259.8
y = 259.8/2 = 129.9 degrees.
so x = 129.9 - 79.6 = 50.3 degrees.
See if it worked. x = 129.9 degrees, y = 50.3 degrees, x + y = 180 so we found the correct two angles! :-)
The sum of two numbers is 100; the first number is 12 less than the second number? What equation best represents the following
Answer:
Let the first number be f.
Let the second number be s.
f = s-12
f+s = 100
Substitute the f in the first equation for the second equation.
s-12+s = 100
2s-12 =100
2s = 112
s = 56
Therefore f = 56-12 = 44
The 2 numbers are 56 and 44.

7) Find the base of a triangle whose height is 12cm, and area is 96cm? Your answer
Answer:
16 cm
Step-by-step explanation:
Area of triangle= ½ ×base ×height
Substitute given information into the formula:
96= ½ ×base ×12
Simplify:
96= 6 ×base
Divide both sides by 6:
base= 96 ÷6
base= 16 cm
Answer:
16 cm[tex] \\ [/tex]
Step-by-step explanation:
It is given that, the height of a triangle is 12cm, and its area is 96cm² and we have to find the base of triangle.
[tex] \\ [/tex]
To find the base of the triangle, we have to know this formula :
[tex] \\ {\longrightarrow \pmb{\frak {\qquad \frac{1}{2} \times Base \times Height = Area_{(Triangle)} \:}}} \\ \\[/tex]
Now, substituting the values in the formula :
[tex]{\longrightarrow \pmb{\sf {\qquad \frac{1}{2} \times Base \times 12 = 96 \:}}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad \frac{1}{ \cancel2} \times Base \times \cancel{12 } = 96 \:}}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad {1} \times Base \times 6 = 96 \:}}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad Base \times 6 = 96 \:}}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad Base = \frac{96}{6} \:}}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\frak {\qquad Base = 16\:}}} \\ \\[/tex]
Therefore,
The base of the triangle is 16 cmThe banana bread card states it serves 10 people. How much flour is required to make enough bread for 30 people?
========================================================
The card says we need 1 & 1/2 cups of flour
Let's convert this to decimal form
1 & 1/2 = 1 + 1/2
1 & 1/2 = 1 + 0.5
1 & 1/2 = 1.5
The mixed number 1 & 1/2 is equivalent to the decimal number 1.5
Now multiply this by 3. This is because the recipe originally serves 10 people, but we want to serve 3 times as many people (3*10 = 30 total).
So, 3*1.5 = 4.5
Now convert back to a mixed number
4.5 = 4 + 0.5
4.5 = 4 + 1/2
4.5 = 4 & 1/2
We'll need 4 & 1/2 cups of flour.
----------------------
Here's another way to approach the problem
Multiply 3 by 1 & 1/2 to get
3*(1 & 1/2) = 3*(1 + 1/2)
3*(1 & 1/2) = 3*1 + 3*1/2
3*(1 & 1/2) = 3 + 3/2
3*(1 & 1/2) = 3 + (2+1)/2
3*(1 & 1/2) = 3 + 2/2 + 1/2
3*(1 & 1/2) = 3+1 + 1/2
3*(1 & 1/2) = 4 + 1/2
3*(1 & 1/2) = 4 & 1/2
Dominic goes jogging every morning. If m represents the number of miles he jogs each day, which expression represents the total number of miles he jogs in a week?
7 m
7 + m
7 minus m
StartFraction 7 over m EndFraction
Answer:
The expression which represents the total number of miles he jogs in a week is 7 m ⇒ A
Step-by-step explanation:
Let us solve the question
∵ Dominic goes jogging every morning
∵ m represents the number of miles he jogs each day
→ That means he jogs m miles every day
∵ There are 7 days in a week
→ That means he jogs m miles every day for 7 days
∵ m + m + m + m + m + m + m = 7 × m
∴ He jogs in 1 week 7 × m miles
∴ He jogs 7 m miles in a week
The expression which represents the total number of miles he jogs in a week is 7 m

Devaughn is 14 years older than Sydney. The sum of their ages is 110. What is Sydney's age?
Answer:
The answer would be 48
Sydney is 48
Devaughn is 62
48 + 62 = 110
Okays so you start by doing the equation 110 - 14 = 96
then dividing 96 by 2 (96 ÷ 2) which is 48
add 14 to 48 and you will get 62. We can automatically assume that sydney is 48 because when you add 48 to 62, you will get 110. I hope that this helps! ^‿^
