1 42.5* and 3 95*, the sum of all the angles =360*, so Angle J = L and M=K, Angle 1 =M/2

Answer:

B. 3

Step-by-step explanation:

If you were to multiply the top equation by 3 then the x value for the first equation would be 6 and since the bottom equation's x value is -6, if you were to add them, they would cancel eachother off.

LOL hope this makes sense :) Please give brainliest!! Thanks!!

Y1=4(5x-1), y2-=5x+1 and y1 is 344 more than 2 times y2

alisha [4.7K]

$y_1=4(5^x-1)$ and $y_2=5^x+1$

$y_1=344+2y_2$
$y_1=344+2(5^x+1)$
$4(5^x-1) = 344 + 2(5^x+1)$
$(4)(5^x)-4=344+2(5^x)+2$
$4(5^x)-2(5^x)=344+2+4$
$2(5^x)=350$
$5^x= \frac{350}{2}$
$5^x=175$
$log(5^x)=log(175)$
$x(log(5))=log(175)$
$x= \frac{log175}{log5}$
$x=3.21$ (rounded to two decimal places)

How is dividing a whole number by a fraction different from dividing a fraction by a fraction

Vesna [10]

Answer:

Dividing a whole number by a fraction you would just multiply the bottom number of the fraction by the whole number.

Step-by-step explanation:

(here is how to divide a fraction by a whole number, if you need help on that also.)

1. Turn the whole number into a fraction. ( ex: 2=2/1)

2. Multiply the fraction by the whole number fraction.

3. Multiply the tops together and the bottoms together

Dividing A Fraction By A Fraction

1. Arrange the equation

2. Keep the first fraction

3. Change the sign

4. flip the fraction

5. Multiply the tops together and the bottoms together
