MakcuM [25]

Answer:

-36

Step-by-step explanation:

plug in the letters for the numbers, then you get, -8 - 25 - 3. -8 - 25 is -33, then you subtract that to 3. so it should look like, -33 - 3. then simplified even more is -36.

Answer: No

Step-by-step explanation:

$2ab^2$

its exponents are;

a=1

b=2

-------------------------------------------

$10ba^2$

its exponents are;

a=2

b=1

------------------------------------------

For them to be like terms, a = 1 and b = 2 or viceversa in both of them.

(x-4)/(2x+1)-3 can you help me with this question

lilavasa [31]

Answer:

$\frac{(x - 4)}{(2x + 1)} - 3$ $=$ $\frac{-7x- 7}{3x + 1}$

Step-by-step explanation:

Given

$\frac{(x - 4)}{(2x + 1)} - 3$

Required

Solve

Express 3 as a fraction

$\frac{(x - 4)}{(2x + 1)} - \frac{3}{1}$

Take LCM

$\frac{x - 4 - 3(2x + 1)}{3x + 1}$

$\frac{x - 4 - 6x - 3}{3x + 1}$

Collect Like Terms

$\frac{x - 6x- 4 - 3}{3x + 1}$

Simplify like terms

$\frac{-7x- 7}{3x + 1}$

Hence:

$\frac{(x - 4)}{(2x + 1)} - 3$ $=$ $\frac{-7x- 7}{3x + 1}$

Two cars are traveling on two different routes, one 43 miles longer than the other. The car traveling on the longer route travel

dedylja [7]

Answer:

Step-by-step explanation:

Let "s" be the the speed of the car taking the shorter route in $\frac{mi}{hr}$ ,

Let "s-2" the speed of the cat taking the longer route in $\frac{mi}{hr}$ ,

Let "d" be the distance of the shorter route in miles and "d+43" be the distance of the longer route in miles.

Now, Equation for car taking the shorter route is given as:

$d=s{\times}5$ (1)

and Equation for car taking the longer route is given as:

$d+43=(s-2){\times}6$ (2)

Now, substitute equation (1) in (2), we get

$5s+43=6s-12$

⇒ $43+12=s$

⇒ $s=55$

Therefore, equation (1) becomes,

$d=5s=5(55)=275$

Thus, the shorter route is =275 miles and the longer route is =d+43=275+43= 318 miles.
