Which answer choice shows the number of hours in 51/2 days

liq [111]

Hey there,

The answer would be 132 hours..There is 24hours in a day so you multiply 24•5=120 then a half if a day is 12 hours, so you then add 12 to 120 which you get 132..

The solution has to be a value of x. Since you already have x, you just have to plug in the value and see what fits. In this case thats the third from the top:

5^2 - 10*5 + 25 = 0

25 - 50 + 25 = 0

0 = 0

Hope it helps!

Solve for all values of x (x+9)2=4

serg [7]

Answer:

x = -7

Step-by-step explanation:

you have to distribute the 2 to what is in the parenthesis, then you get left with 2x+18=4 so subtract the 18 from both sides leaving you with 2x=-14 so you divide both by 2 leaving you with x=-7.

A fisherman can row upstream at 5mph and downstream at 10mph he started rowing upstream until he got tired and then rowed downst

AlekseyPX

We have been given that the upstream speed is $5 mph$ and the down stream speed is $10mph$ .

Let the fisherman traveled a distance of x miles.

The total time of the trip is 6 hours.

Relations between speed (s), time (t) and distance (d) is $s = \frac{d}{t}$

Hence, $t= \frac{d}{s}$

Time upstream + time downstream = 6

$\frac{x}{5} +\frac{x}{10} =6$

lcm = 10

$\frac{2x+x}{10} =6$

=> $\frac{3x}{10} =6$

Cross multiplying, $3x= 60$

x = 20 miles .. Answer.

Solve for x. 7^8=7^8×7^x

denis-greek [22]

Answer:

x = 0

Step-by-step explanation:

Apply the exponent rule.

$7^8=7^{x+8} \\$

If $a^{f(x)} = a^{g(x)} then f(x) = g(x)$

8 = x + 8

x = 0
