Answer:
The solution of this system of equations is (3 , -8)
Step-by-step explanation:
The given system is
x + 2y = -13
12x + 5y = -4
We make x the subject of the first equation and put it into the second:

We put this expression for x into the second equation
12(-13-2y)+5y=-4
-156-24y+5y=-4
-24y+5y=-4+156
-19y=152
y=-8
We substitute y=-8 into x=-13-2y to get:

The solution of this system of equations is (3 , -8)
Since the problem stated that 7/9 of the participants were from Wisconsin, so 2/9 of it were not from Wisconsin. Now out of 7/9 participants, 3/5 of them were 12 years old, so 2/5 of them are not 12 years old. Since we now know the fractions, we'll get the equation 7/9 x 3/5 multiply 7 and 3 then divide it to the product of 9 and 5 to have the answer of 7/15. 7/15 of the participants of the camp in Green Bay is from Wisconsin and are 12 years old.
Answer:
14
Step-by-step explanation:
(11/3)/(1/4)=14 2/3 which means you can make 14 complete bows
Answer:
Step-by-step explanation:
So angle 1 and 2 are both obtuse angles. They are considered adjacent angles as well.
Hope this helps
<span>12(X+20)=372
12X+240=372
Subtract the 240
</span>12X=372-240 ----> 12X=132
Divide by 12
12X/12=132/12 ---> x = 11
