10c + 20 = 40
c =

Answers

Answer 1
C= 2


...................................
Answer 2
The correct answer is 2.

Step 1: in order to solve an equation, you need to isolate the variable. Meaning, you need to get it by itself In this case, the variable is c. So, what you will do is subtract 20 on both sides of the equation and you should end up with 10c=20.

Step 2: We still need to get c by itself so, we have to do the inverse operation of multiplication, which is division. We then divide 10 on both sides of the equation. The answer you should come up with is c=20

LaTanya leaves her house at 12:30 P.M. and bikes at /12 miles per h to Marta’s house. She stays at Marta’s house for 90 min. Both girls walk back to LaTanya’s house along the same route at ./.2.5 miles per h They arrive at LaTanya’s house at 3:30 P.M. How far is Marta’s house from LaTanya’s house?

Answers

The answer should be 3.1 miles

Marta's house is 3.10 miles from Latanya's house

What is speed?

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.

Given that Latanya leaves her house at 12:30 p.M. She bikes at 12 mi/hr to Marta's house She stays at Marta's house for 90 minutes Both girls walk back to Latanya's house at 2.5 mi/h They arrive at Latanya's house at 3:30 p.M.

We need to know how far is Marta's house from Latanya's house

∵ Latanya starts her trip at 12:30 p.M.

∵ She returns home at 3:30 p.M.

∴ The time of her trip is  → 3:30 - 12:30 = 3 hours

- But she stays at Marta's house for 90 minutes

∵ 1 hour = 60 minutes

∴ 90 minutes = 90 ÷ 60 = 1.5 hours

∴ The time from her house to Marta's house and from Marta's house to her house is → 3 - 1.5 = 1.5 hours

Assume that the distance from her house to Marta's house is d and the time from her house to Marta's house is t₁ and the time from Marta's house to her house is t₂

∵ Latanya bikes at 12 mi/h to Marta's house

∵ Distance = speed × time

∴ d = 12 × t₁

∵ Both girls walk back to Latanya's house at 2.5 mi/h

∴ d = 2.5 × t₂

Equate the two expressions of d

∴ 12  = 2.5  ⇒ (1)

∵ t₁ + t₂ = 1.5

Subtract  from both sides

∴ t₂ = 1.5 - t₁  ⇒ (2)

Substitute equation (2) in equation (1)

∴ 12t₁  = 2.5(1.5 - t₂ )

∴ 12  = 3.75 - 2.5

Add 2.5 t₁ to both sides

∴ 14.5t₁  = 3.75

Divide both sides by 14.5

t₁ = 15 / 38 hour

∴ She spends 15/58 hours biking Marta's house. Let's find d

∵ d = 12t₁

∴ d =  12 x ( 15 / 38 ) miles

Therefore, Marta's house is 3.10 miles from Latanya's house

It takes Kevin 15 minutes to drive 5 1/2 miles.
How many miles does Kevin drive per minute?
a) 11/30
b) 5/6
c)2 8/11
d) 3

Answers

Answer:  11/30 miles per minute

Step-by-step explanation:

To get miles per minute

Divide the distance by the time

5 1/2 ÷ 15 . Change 5 1/2  to an improper fraction 11/2

invert the divisor and multiply: (Multiply by the reciprocal of 15: 1/15)

11/2 × 1/15 = 11/30

Here, we are required to determine how many miles does Kevin drive per minute.

The number of miles Kevin drives per minute is 0.3667miles.

According to the question, Kevin drives 5 1/2 miles (5.5 miles) in 15 minutes.

To determine how many miles Kevin drives per minute, we need to determine Kevin's speed over the 15 minutes in which he covered 5.5 miles.

Speed = distance/time

Speed = 5.5miles/15minutes

Therefore, Speed = 0.3667 miles per minute.

Ultimately, Kevin drives 0.3667miles per minute.

(0.25)

Step 1: Simplify both sides of the equation.

Step 2: Divide both sides by 1.885714.

1.885714x

x=0.025253

The value of x from the given ratios 2 2/7 :(0.6x)= 4/21 :0.25 will be 5.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

[tex]2 \frac{2}{7}[/tex] :(0.6x) = 4/21 :0.25

Therefore, solve the mixed fraction, we get

16/7 :(0.6x) = 4/21 :0.25

Step 1: Simplify both sides of the equation.

16/7 :(0.6x) = 4/21 :0.25

(16/7) / (0.6x) = (4/21 ) / (0.25 )

Step 2: Divide both sides

(16/7) / (0.6x) = (4/21 ) / (0.25 )

Cross multiply:

(16/7) x (0.25 )= (4/21 ) x (0.6x)

4/7 = 2.4x /21

84 = 16.8x

Divide both sides by 16.8:
