Solve for n.
m=n/r+t

Answers

Answer 1

Answer:

n = m r - r t

Step-by-step explanation:

Solve for n:

m = n/r + t

Hint: | Reverse the equality in m = n/r + t in order to isolate n to the left hand side.

m = n/r + t is equivalent to n/r + t = m:

n/r + t = m

Hint: | Isolate terms with n to the left hand side.

Subtract t from both sides:

n/r = -t + m

Hint: | Solve for n.

Multiply both sides by r:

Answer: n = m r - r t

Given ∠2 and ∠4 are vertical angles.
Prove ∠2 ≅ ∠4

Answers

A proof is a set of logical statements that show that a statement is rational and true. See the proof for the above statement below.

What is the proof that ∠2 ≅ ∠4?

Given ∠2 and ∠3 make a linear pair hence,

∠2 + ∠3 = 180

∠3 = 180 - ∠2....................1

Again ∠3 and ∠ translate to a linear pair. Hence

∠ 3 + ∠4 = 180, thus

∠3 = 180 - ∠4  .........................2

Drawing from 1 and 2, we get

180 - ∠2 = 180 -∠4 [Remove 180 from both sides]

⇒ -∠2 = -∠4

or ∠2 = ∠4

Thus, we have proven that ∠ and ∠4 are congruent angles.

The formula P=c+m can be used to determine price P of an
item that costs c cents and a markup of m cents. The markup on a
can of juice is 25 cents. What is an equivalent version of this
Formula solved for c?

Answers

Answer:

c = P-25

Step-by-step explanation:

Given the formula P = c+m which is used to determine price P of an  item that costs c cents and a markup of m cents. To get the value of c, we will make c the subject of the formula;

P = c+m

subtract m from both sides

P-m = c+m-m

P-m = c

c = P-m

Given the price of mark up on a can of juice to be 25 cents, we will substitute m = 25 into the resulting expression as shown;

c = P-25

Hence the equivalent version of this  formula solved for c is c = P-25

If RS = 17, ST = x + 6, and RT = 3x - 5, What is ST.

Answers

Answer:

ST = 20

Step-by-step explanation:

Line segment RS and segment ST must add up to line segment RT

Step 1: Define

RS = 17

ST = x + 6

RT = 3x - 5

Step 2: Set up equation

mRS + mST = mRT

17 + x + 6 = 3x - 5

Step 3: Solve for x

x + 23 = 3x - 5

23 = 2x - 5

28 = 2x

x = 14

Step 3: Find mST

ST = x + 6

ST = 14 + 6

ST = 20

Tara bakes 225 cookies in 5 hours, and she uses 8 pounds of sugar. She divides 225 by 5 to get a rate of 45. Which of the following corresponds to this rate?
A cookies per pound
B. O pounds per hour
c. cookies per hour
D. hours per cookie

Answers

Answer:

c

Step-by-step explanation: Cookies per hour because if you divide the amount of cookies by the time it took to make them what your gonna get out of it is the amount of cookies baked per hour.

The rate 45 corresponds to cookies per hour.

What is Rate?

Rate is defined as the ratio of two different quantities with different units. Ratio of two different quantities with the denominator equals 1 is called unit rate.

Unit rate, on the other hand can be defined as the amount of one quantity in a single unit of the other quantity.

For example, speed is the unit rate of distance and time.

Number of cookies Tara bakes in 5 hours is given as 225.

When 225 is divided by 5 to get a rate of 45, we are actually dividing the number of cookies with time to get how many cookies can be made in 1 hour.

So a rate of 45 implies that 45 cookies are baked by Tara in a single hour, which is the unit rate.

This means that this rate means cookies per hour.

Hence, the rate 45 corresponds to cookies per hour.

Answer:

[tex]z=\frac{at-67}{45+a}[/tex]

Step-by-step explanation:

Step 1: Write out equation

a(t + z) = 45z + 67

Step 2: Distribute a

at + az = 45z + 67

Step 3: Subtract 67 on both sides

at + az - 67 = 45z

Step 4: Subtract az on both sides

at - 67 = 45z + az

Step 5: Factor out z

at - 67 = z(45 + a)

Step 6: Divide both sides by 45 + a

[tex]z=\frac{at-67}{45+a}[/tex]

Answer:

Step 1: Write out equation

a(t + z) = 45z + 67

Step 2: Distribute a

at + az = 45z + 67

Step 3: Subtract 67 on both sides

at + az - 67 = 45z

Step 4: Subtract az on both sides

at - 67 = 45z + az

Step 5: Factor out z

at - 67 = z(45 + a)

Step 6: Divide both sides by 45 + a
