<u>Answer:
</u>
The ordered pair value of (x, y) is (6,-11)
<u>Solution:
</u>
Given Equations are
Let 8x + 15y = -117 be Equation 1 and 4x + 9y=-75 be Equation 2.
Solving Equations 1 and 2 to get the value of x and y.
Multiply Equation 2 with 4.
16x + 36y = -300
On dividing the above expression by 2, we get
8x + 18y = -150 (Change the sign to get the value of y).
-8x - 18y = 150 --- eqn 3
Now solving eqn 1 and eqn 3
8x + 15y = -117
-8x - 18y = 150
By cancelling 8x and -8x in eqn 1 and eqn 3
-3y = 33
y = -11
Substitute the value y in Equation 2.
4x + 9 (-11) = -75
4x – 99 = - 75
4x= -75 +99
4x = 24
x=6
Hence the value of x and y is (6,-11).
Answer:
1/6 ton of fish is fed during the feeding at night.
Step-by-step explanation:
The fish fed in the morning is 
tons, and during after noon the fish fed is 
more than in the morning; or
and let us call the tons of fish fed at night 
, then if the total tons of wish fed during the is 
, we have
Let us add the numerators on the left side and we get:
and subtract 
from both side to isolate 
and since 
, we have
the common denominator of the fractions is 6; therefore, we rewrite the equation as
and subtract the numerators to get:
which the number of tons fed during the feeding at night.
Answer:
She can make 2 2/5 necklace in one hour
Step-by-step explanation:
60/15=4 so she makes 3/5*4=12/5=2 2/5
The soda was $1.00.
Hot Dog- $3.50
Peanuts- $4.00
3.50+4.00= 7.50
Total paid is $11.50-$7.50= $4.00-$3.00(coupon)= $1.00
The answer is 21% because a 6-oz fillet of salmon contains about 750 mg of potassium. 3500-750 equals 2750, meaning that whichever percent closest to that answer is correct. 3500 - 21% = 2760 which is the closest number to the correct percentage therefore A. Is the answer.
