Alinara [238K]3 years ago

Answer:

(3, 3)

Step-by-step explanation:

do you need to show your work or just the answer?

-3x+7y=12                                   mulitply both sides by 3 of the bottom.

x-2y=-3

-3x+7y=12                    

3x-6y=-9           < which turns into this

Then you have to sum the equations (vertically) to eliminate one variable.

y=3

Then substitute the given value of "y" into the equation

x-2 * 3=-3    then solve the equation for x      (x=3)

y=3   x=3    (3, 3)

*Check your answers.

-3*3+7*3=12

3-2*3=-3

12=12

-3=-3

(-3, -3)

If a 20-foot ladder makes a 65° angle with the ground, how many feet up a wall will it reach? Round your answer to the nearest t
zysi [14]

We have an angle, a hypotenuse - the ladder length - and we're looking for the opposite side......the sine seems the way to go, here.....

sin 65 = opp / 20   multiply both sides by 20

20 sin 65 = opp = about 18.13 ft up the wall

One group (A) contains 615 people. Three-fifths of the people in group A will be selected to win $50 fuel cards. There is anothe
mezya [45]
The answer is 246:157.

Step by Step:

Group A:

First, figure out 1/5 of the people in group A. ( 615/5 = 123 )

Find 2/5 ( the amount of people who lost ) ( 123*2 = 246 )

Group B:

They received the same amount of fuel cards, so you take 526 - 369 ( 3/5 of the last group, or the winners, which is the amount of cards they received ) = 157.
