Answer:
Step-by-step explanation:
Since both equations have 
, we can subtract the second equation from the first to try and solve for 
:
With this, we can plug the value back into the first equation to solve for 
:
Therefore, the solution is 
Ok so lets start with the 5 dozen there are 12 eggs in one dozen so we do 12*5 which gives us 60 and then we figure out what 3/4 of 12 is that sounds confusing the way i typed it. an example is make four piles each evenly numbered so four piles of three so take three of those piles which gives you the number nine so 60 + 9 gives you 69 so Jesse has 69 eggs.
Answer:
$0.67
Step-by-step explanation:
if you're trying to find the unit price of each eraser then divide the cost by the number of units.
$5.36÷8=$0.67
Answer:
x = 52 degrees
Step-by-step explanation:
Since HI and JK are parallel, that means they have congruent corresponding angles. Which basically means that angle K (62 degrees) is a corresponding angle to angle I. So angle I would be 62 degrees, too.
All you need to do is add 66 and 62 together, and subtract the sum from 180 (you're subtracting from 180 because the angles of a triangle all add up to 180 degrees).
66 + 62 = 128
180 - 128 = 52
(-2 1/2)×(-3 1/2) = (2 1/2)×(3 1/2) . . . . deal with the signs up front. The product of two negatives is a positive.
... = 2×(3 1/2) + (1/2)×(3 1/2) . . . . . use the distributive property
... = 2×3 + 2×(1/2) + (1/2)×3 + (1/2)×(1/2) . . . . and again
... = 6 + 1 + 3/2 + 1/4
... = 7 + (1 1/2) + 1/4
... = 8 + 2/4 + 1/4
... = 8 3/4
