**Answer 1**

The relationship between the **points **is an illustration of **similar shapes**.

The **length of AB **is 0.43

The given parameters are:

[tex]\mathbf{BE = 1.8}[/tex]

[tex]\mathbf{CD = 9}[/tex]

[tex]\mathbf{BC = 1.7}[/tex]

From the question (see attachment), we have the following observations:

BE **corresponds **to CDAB **corresponds **to AC

So, the **equivalent ratio **is:

[tex]\mathbf{AB:BE =AC:CD }[/tex]

Substitute known values

[tex]\mathbf{AB:1.8 =AC:9 }[/tex]

Express as fractions

[tex]\mathbf{\frac{AB}{1.8} =\frac{AC}{9} }[/tex]

Multiply both sides by 1.8

[tex]\mathbf{AB =\frac{AC}{5} }[/tex]

*AC = AB + BC*

So, we have:

[tex]\mathbf{AB =\frac{AB + BC}{5} }[/tex]

Substitute 1.7 for BC

[tex]\mathbf{AB =\frac{AB + 1.7}{5} }[/tex]

Multiply through by 5

[tex]\mathbf{5AB =AB + 1.7}[/tex]

Collect like terms

[tex]\mathbf{5AB -AB =1.7}[/tex]

[tex]\mathbf{4AB =1.7}[/tex]

Divide both sides by 4

[tex]\mathbf{AB=0.425}[/tex]

Approximate

[tex]\mathbf{AB=0.43}[/tex]

Hence, the **length of AB **is 0.43

Jamal has two trails. the first trail is 5 1/3 miles long, and the second trail was 1 3/4 times as long as the first trail. how many miles did Jamal walk?

### Answers

**Answer:**

The correct answer is Jamal hiked [tex]14\frac{2}{3}[/tex] miles.

**Step-by-step explanation:**

To solve this math problem, you will need to convert mixed numbered fractions, into improper fractions.

To do that, you will need to multiply the whole number with the denominator (Ex: 5 × 3 = 15), then when you receive the answer, add the answer with the numerator (Ex: 15 + 1 = 16), finally, you should receive a new answer, and to finalize the improper fraction, you always need to keep the denominator the same (Ex: The denominator is 3 so use the new answer as a numerator replacement. [tex]\frac{16}{3}[/tex])

--

After you have converted all the mixed numbers into improper fractions in the math problem, you are then able to use multiplication.

--

But first we have to calculate how long the second trail was.

[tex]\frac{7}{4} *\frac{16}{3} =7*\frac{4}{3} =\frac{28}{3} =9\frac{1}{3}[/tex] miles. Then, convert the mixed number into improper. ([tex]\frac{28}{3}[/tex])

--

Now add the number of miles of **both** trails.

[tex]\frac{16}{3} +\frac{28}{3} =\frac{44}{3} =14\frac{2}{3}[/tex]

With the result as: [tex]14\frac{2}{3}[/tex]

Oy=4

Oy=7

Oy= 4

Oy=6

### Answers

**Answer:**

y = 6

**Step-by-step explanation:**

[tex]3(y - 5) + 2 = 5 \\ 3y - 15 + 2 = 5 \\ 3y - 13 = 5 \\ 3y = 5 + 13 \\ 3y = 18 \\ \\ y = \frac{18}{3} \\ \\ y = 6[/tex]

**I hope I helped you****^****_****^**

The **solution **of the **equation **3(y - 5) + 2 = 5 gives the result y = 6.

Thus, option (d) is **correct**.

An **equation **is a mathematical statement that shows that two expressions are **equal**. It consists of two sides separated by an equal sign (=).

Let's solve the equation step by step:

3(y - 5) + 2 = 5

First, **distribute **the 3 on the left side:

3y - 15 + 2 = 5

**Combine **the constants on the left side:

3y - 13 = 5

Now, **isolate **the variable y by **adding **13 to both sides:

3y = 18

Finally, **divide **both sides by 3 to solve for \(y\):

y = 18/3

y = 6

So, the **solution **to the **equation **is y = 6.

Thus, option (d) is **correct**.

A taxi charges a flat rate of $1.75, plus an additional $0.65 per mile. If Erica has at most $10 to spend on the cab ride, how far could she travel? Write an inequality expression that represents the situation and solve! Explain your reasoning! You can copy/paste the needed symbols as needed: ≥ ≤

### Answers

**Answer: **

**The inequality expression would be 1.75+0.65x ≥10**

**She would be able to ride ~12.7 miles or just 12 miles rounding down. **

**Step-by-step explanation:**

Following mx+b, the m value would be 0.65 because it is added per mile.

The 1.75 would be the b value because it is the starting value.

So the equation would look like ** 1.75+0.65x. **To know if the 10 value would be less than or more than, we have to know if 10 is the limit value or starting value. Because 10 is our limit value, we will use greater than or equal to.

To know how many miles Erica could travel, we would have to subtract 1.75

from 10. We would get 8.25. We would then divide 8.25 by 0.65. so the number of miles she can travel is **~12.7 miles or just 12 miles rounding down.**

Linda is twice as old as Vera. Tanya is four less than four times the age of Linda. Their total age is two more than nine times the age of Vera. How old is Tanya, in years?

### Answers

[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]

Let the age of Vera be x,

Linda's age = 2x

Tanya's age = (4 × 2x) - 4 = 8x - 4

Total Age = 9x + 2

so, let's Solve for x :

[tex]x + 2x + 8x - 4 = 9x + 2[/tex]

[tex]11x - 4 = 9x + 2[/tex]

[tex]11x - 9x = 2 + 4[/tex]

[tex]2x = 6[/tex]

[tex]x = 3[/tex]

Age of Tanya :
