How do you solve a/7+5/7=2/7

Mathematics
1 answer:
Anton [14]3 years ago
4 0
\frac{a}{7} + \frac{5}{7} = \frac{2}{7} \\ \frac{a + 5}{7} = \frac{2}{7} \\ 7(\frac{a + 5}{7}) = 7(\frac{2}{7})
a + 5 = 2
a + 5 - 5 = 2 - 5
a = -3

Hope this helps! :)

The percentage change of a ratio of two variables is approximately the percentage change in the numerator _____ the percentage c
olchik [2.2K]

Answer:

"The percentage change of a ratio of two variables is approximately the percentage change in the numerator <u>minus</u> the percentage change in the denominator."

Step-by-step explanation:

The percent change in a number is determined by dividing the difference between the new number and original number by the original number and multiplying the result by 100.

Suppose the original ratio of two numbers is: \frac{25}{100}.

And the new ratio is: \frac{75}{100}

The percent change is:

Change\%=\frac{75-25}{100}\times100=\frac{50}{100}\times100=50\%

Thus, the complete statement is:

"The percentage change of a ratio of two variables is approximately the percentage change in the numerator <u>minus</u> the percentage change in the denominator."

a motorboat travels 305km in 5 hours going upstream and 651km in 7 hours going downstream. What is the rate of the boat in still
Ghella [55]
Recall your d = rt, distance = rate * time.

b = speed rate of the boat.

c = speed rate of the current.


keeping in mind that, as the boat goes Upstream, against the current, it's speed is not "b", but is really " b - c ", because the current is subtracting speed from it.

likewise, when the boat is going Downstream, because is going with the current, is really going faster at " b + c ".

\bf \begin{array}{lccclll}&#10;&\stackrel{km}{distance}&\stackrel{kmh}{rate}&\stackrel{hours}{time}\\&#10;&------&------&------\\&#10;Upstream&305&b-c&5\\&#10;Downstream&651&b+c&7&#10;\end{array}&#10;\\\\\\&#10;\begin{cases}&#10;305=(b-c)(5)\implies 61=b-c\implies 61+c=\boxed{b}\\&#10;651=(b+c)(7)\implies 93=b+c\\&#10;----------------------\\&#10;93=\boxed{61+c}+c&#10;\end{cases}&#10;\\\\\\&#10;93=61+2c\implies 32=2c\implies \cfrac{32}{2}=c\implies 16=c

what is the speed of the boat?  well, 61 + c = b.

bagirrra123 [75]

Answer:

See below

Step-by-step explanation:

The three angles inside of the triangle sum to 180

11x + 4       + 3x      + 78 = 180

14x +82 =180

x = 7

then B =   11x + 4    = 11(7) + 4 = 81 degrees

C =  3x = 21 degrees
