Answer:
(7, -3)
Step-by-step explanation:
Add the two equations to eliminate x:
7y = -21
Then solve 7y = −21 for y:
= 
(<em>Divide both sides by 7)</em>
y = -3
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
2y - 3x = -27
Substitute -3 for y in 3y - 3x = -27:
(2)(-3) - 3x = -27
-3x - 6 = -27 (<em>Simplify both sides of the equation</em>)
-3x - 6x + 6x = -27 + 6 (<em>Add 6 to both sides</em>)
-3x = -21
= 
(<em>Divide both sides by -3</em>)
x = 7
24+24+11+11=60?
48+22=60?
60=60?
:D You're correct
Answer:
6
Step-by-step explanation:
The shape is a hexagon so it will have 6 angles :)
You change the 2/3 into 4/6 and do it again so it would be 8/12 then keep ding that till you get the awnswer
You can write 1/4 as a decimal, equivalent fraction, and a percent.
To change 1/4 into a decimal, divide the numerator by the denominator. You will get 0.25. To make 1/4 into a percent, multiply the decimal by 100 or just move the decimal two places to the right. The percent is 25%. To make 1/4 into another equivalent fraction, multiply the numerator and denominator by the same number. For example, you can multiply the numerator by 2 and the denominator by 2. So, another equivalent fraction for 1/4 is 2/8.
Hope it helps :)
