8x-5y=15 <br>6x+4y=43<br>solve the system by any method​
Sedbober [7]

Answer:

x=\frac{275}{62} , y=\frac{127}{31}

Step-by-step explanation:

<h3>I will use the elimination method.</h3>

We want to make the X's the same:

24x-15y=45

24x+16y=172

Because the signs of the X's are the same we subtract the 2 equations to make:

(I put the second one on top of the 1st)

31y=127

So:

y=\frac{127}{31}

Substitute y into either equation 1 or 2:

(I chose equation 1)

8x-5(\frac{127}{31})=15

8x=5(\frac{127}{31}) + 15

x=\frac{5(\frac{127}{31})}{8}

So:

x=\frac{275}{62}

Lapatulllka [165]
To find the total from the percent part you have, you divide the part by the percentage.
1.50÷0.05=30
The total is $30
The total the store charged, including sales tax, is $31.50.

8+(14+6) FIND EASIER EXPLAIN WHY
alexandr1967 [171]

Hi there and welcome to Brainly!


The answer to 8+(14+6) = 28. The reason for this is you add what is in parenthesis first then you add the number outside of the parenthesis. This follows the PEMDAS rule which is called the order of operations. PEMDAS is an acronym which stands for Parenthesis, Exponents, Multiplication/Division, and Addition/Subtraction, this is the order you should follow when solving any problem.


If you have anymore questions please feel free to ask them.

The volume of a cylinder, V, in terms of radius, r,
Igoryamba

Answer:

See explanation

Step-by-step explanation:

Volume of a cylinder = πr²h

Solve for r

V = π * r² * h

r² = V/πh

Find the square root of both sides

r = √V/πh

If height = 6 meters and volume = 300 cubic meters. Find r

r = √V/πh

= √(300/3.14*6)

= √(300/18.84)

= √15.923566878980

r = 3.9904344223381

Approximately,

r = 4 meters
