Answer:

<h3>\boxed{ \sf{ \bold{ \huge{ \boxed{ \frac{29}{5} }}}}}</h3>

Option B is the correct option.

Step-by-step explanation:

\sf{ \frac{3}{5}  =  \frac{x - 1}{8} }

Apply cross product property

⇒\sf{ 5(x - 1) = 3 \times 8}

Distribute 5 through the parentheses

⇒\sf{5x - 5 = 3 \times 8}

Multiply the numbers

⇒\sf{5x - 5 = 24}

Move 5 to right hand side and change it's sign

⇒\sf{5x = 24 + 5}

Add the numbers

⇒\sf{5x = 29}

Divide both sides of the equation by 5

⇒\sf{ \frac{5x}{5}  =  \frac{29}{5} }

⇒\sf{x =  \frac{29}{5} }

Hope I helped!

Best regards!!

hodyreva [135]

Answer:

80%

Step-by-step explanation:

Abdul is riding on a bike course

The bike course is 80 miles long

So far he has rifden 64 miles of the course

Therefore the percentage of the course in which Abdul has ridden so far can be calculated as follows

= 64/80 × 100

= 0.8 × 100

= 80%

Hence Abdul has ridden 80% of the course

The measure of the angles of a triangle are in the extended ratio of 3 : 7 : 10. Find the measures of the angles.
olga2289 [7]

Answer:

A. 27 degrees, 63 degrees, 90 degrees.

Step-by-step explanation:

Let the angle of the triangle be x

<u>Given the following data;</u>

3 : 7 : 10 = 3x : 7x : 10x

We know that the sum of the sides of a triangle is equal to 180 degrees.

3x + 7x + 10x = 180

20x = 180

x = 180/20

x = 9

<u><em>For the first side;</em></u>

3x = 3 × 9 = 27°

<em><u>For the second side;</u></em>

7x = 7 × 9 = 63°

<em><u>For the third side;</u></em>

10x = 10 × 9 = 90°

Therefore, the ratio of the angles of the triangle is 27° : 63° : 90°.

Solve the system of equations and choose the correct ordered pair.
nasty-shy [4]
The answer is D

Because if you replace the variables just by testing them they give the answer as X=-3 and Y=3.
In which replacing:
3(-3)+5(3)=6
and with the other equation we've got:
4(-3)+2(3)=-6
so they comply with the required to be the correct answer, even though you can make a system of equation.
