Answer:

$3x+4=5x-10$

Step-by-step explanation:

we know that

The solution of the linear system of equations is the intersection point both graphs

using a graphing tool

we have

$y=3x+4$ ------> equation A

$y=5x-10$ ------> equation B

To find the solution equate the equation A and equation B

$3x+4=5x-10$

Solve for x

$5x-3x=4+10$

$2x=14$

$x=7$

Find the value of y

$y=3x+4$ ------> $y=3(7)+4=25$

the solution is the point $(7,25)$

see the attached figure to better understand the problem

You've decided to go cave diving. the route between a and b in 8025 meters long and the average diver can swim 15 meters per min

Anastasy [175]

$\text{The route between A and B is 8025 meters.}\\
\\
\text{And an average diver can swim 15 meters per minute.}\\
\text{we need to find the time it will take to complete diving.}\\
\\
\text{by the time distance formula, we know that}\\
\\
\text{Time}=\frac{\text{Distance}}{\text{Speed}}\\
\\
\text{so using this the time taken to complete the dive is}\\
\\
\text{Time}=\frac{8025}{15}\\
\\
\Rightarrow \text{Time}=535 \text{ minutes}$

So the time taken to complete the dive is: 535 minutes

2 questions correct anwser gets brainlyess

Vlada [557]

Answer:

Question 1: x=55
Question 2: m∠A=45°

Step-by-step explanation:

Question #1

- Since it is an isosceles triangle, this means that the base angles have the same value.

- The angle sum is 180°

Solve

2x+35+35=180

2x+70=180

2x=110

x=55

Question #2

- Since it is given there is a right angle, this means the angle is 90°

- The angle sum is 180°

Solve

5x+5x+90=180

10x+90=180

10x=90

x=9

It asked to find m∠A, which is 5x. So 5x=5(9)=45°

Hope this helps!! :)

John's lunch at a restaurant costs $13.00, without tax. He leaves the waiter a tip of 17% of the cost of the lunch, without tax.

Pani-rosa [81]

Answer:

$15.21

Step-by-step explanation:

17% of $13=0.17*13=2.21

13 (the price of the actual lunch) +2.21= 15.21

Alternatively, you can just do the operation:

13*(1+0.17)=15.21

This is because 1*13=the price of the actual lunch and 0.17*13=the price of the tip
