24 because 12 times 2 is equal to 24
Answer:
19/24
Step-by-step explanation:
From the question we are informed that Lisle bought 3/8 pounds of red grapes and 5/12 pound of green grapes
✓3/8 pounds of red grapes and 5//12
✓First thing to do is to add the fractions
But we need " the least common denominator" because their denominator are not the same, we need to make it the same...
✓ The two denominator ( 8 and 12) are both factor of 24, therefore their "least common denominator" is 24.
✓To make 3/8 pounds of red grapes has a denominator of 24, we multiply both the denominator & numerator with factor of 3.
3/8 = (3×3)/(8×3)=9/24
✓To make 5/12 pounds of green grapes has a denominator of 24, we multiply both the denominator & numerator with factor of 2.
5/12= (5×2)/(12×2)= 10/24
✓ we can see they both have the same denominator, then we can now "add both denominators"
(9+10)=19
✓ Then place the addition of the denominators on the least common denominator.
= 19/24.
Therefore, he bought 19/24 of grapes
ANSWER
x=3, y=-4
EXPLANATION
The given system is :
First equation:

Second equation:

Let us multiply the first equation by 7 to get,
Third equation;

Let us multiply the second equation too by 10 to get,
Fourth equation:

Subtract the fourth equation from the third equation:


Divide both sides by 59.

Put y=-4 into the second equation and solve for x.





The solution is x=3, y=-4
that meen EVALUATE (y) at x=4
y=1
The answer would be 0.83171428571
I would usually divide it by putting 29.11 into 35.
