Answer:

x=5

Step-by-step explanation:

x+5 = -3x+25

Add 3x to each side

x+3x+5 = -3x+3x+25

4x +5 = 25

Subtract 5 from each side

4x+5-5 = 25-5

4x = 20

Divide each side by 4

4x/4 = 20/4

x =5

-3r-8(8r+8)=-9(-4+9r)​
natulia [17]

Answer:

r= 7.14 (rounded to 2 decimal places)

Step-by-step explanation:

We have to solve this equation for the value of r. We will use distributive property and basic algebra to solve this.

Distributive property is  a(b+c) = ab + ac

Now, the steps of solving are shown below:

-3r-8(8r+8)=-9(-4+9r)\\-3r -64r-64=36-81r\\-67r-64=36-81r\\-67r+81r=36+64\\14r=100\\r=\frac{100}{14}\\r=7.14

Hence, value of r is 7.14 (rounded to 2 decimal places)

D is the centroid of △ABC. What is the value of x when GD=x+4 and GC=4x+5?
alexira [117]

Answer:

x = 7

Step-by-step explanation:

Because:

GD = x + 4

GC = 4x + 5

And D is the centroid of ABC

So GC = 3GD

<=> 4x + 5 = 3(x + 4)

<=> 4x + 5 = 3x + 12

<=> 4x - 3x = -5 + 12

<=> x = 7

Done!!

You ok?? :))

Tim and Al are bricklayers. Tim can construct an outdoor grill in 5 days. If Al helps Tim, they can build it in only 3 days. How
KATRIN_1 [288]

Answer:

It would take Al 7.5 days to build the grill alone.

Step-by-step explanation:

Since Tim and Al are bricklayers, and Tim can construct an outdoor grill in 5 days, and if Al helps Tim, they can build it in only 3 days, to determine how long would it take Al to build the grill alone should be done the following calculation:

1/5 + X = 1/3

0.20 + X = 0.333

X = 0.333 - 0.20

X = 0.1333333

X = 1 / 7.5

Therefore it would take Al 7.5 days to build the grill alone.

- If f ( x ) = x² + 2x - 1 and g ( x ) = 3x - 2 , then verify the following :
RideAnS [48]

Step-by-step explanation:

Hey there!

Given;

f ( x ) = x² + 2x - 1

g ( x ) = 3x - 2

To verify:

( \frac{f}{g} )(2) =  \frac{f(2)}{g(2)}

LHS:

(\frac{f}{g} )(x) =  \frac{ {x}^{2}  + 2x - 1}{3x - 2}

~ Insert "2" instead of "x".

(\frac{f}{g} )(2) =  \frac{ {2}^{2} + 2 \times 2 - 1 }{3 \times 2 - 2}

Simplify it;

\frac{f}{g} (2) =  \frac{4 + 4 - 1}{6 - 2}

Therefore; (f/g)(2) = 7/4.

RHS:

\frac{f(x)}{g(x)}  =  \frac{ {x}^{2}  + 2x - 1}{3x - 2}

~Insert "2" instead of"x".

\frac{f(2)}{g(2)}  =  \frac{ {2}^{2} + 2 \times 2 - 1 }{3 \times 2 - 2}

Simplify it.

\frac{f(2)}{g(2)}  =  \frac{4 + 4 - 1}{6 - 2}

Therefore, f(2)/g(2) = 7/4.

Since (f/g)(2) = f(2)/g(2) = 7/4.

Well, first you want to figure out how many sentences Jolie has left to read. You can do that by multiplying 120 by 17 which equals 2,040. Then you have to divide 2,040 by 14. The answer to that is about 145.72 which you could just leave at about 145 minutes. And to simplify that even more you could divide by 60 and figure that 145.72 is about 2 hours and 42 minutes.
