First, "boxes of two sizes" means we can assign variables: Let x = number of large boxes y = number of small boxes "There are 115 boxes in all" means x + y = 115 [eq1] Now, the pounds for each kind of box is: (pounds per box)*(number of boxes) So, pounds for large boxes + pounds for small boxes = 4125 pounds "the truck is carrying a total of 4125 pounds in boxes" (50)*(x) + (25)*(y) = 4125 [eq2] It is important to find two equations so we can solve for two variables. Solve for one of the variables in eq1 then replace (substitute) the expression for that variable in eq2. Let's solve for x: x = 115 - y [from eq1] 50(115-y) + 25y = 4125 [from eq2] 5750 - 50y + 25y = 4125 [distribute] 5750 - 25y = 4125 -25y = -1625 y = 65 [divide both sides by (-25)] There are 65 small boxes. Put that value into either equation (now, which is easier?) to solve for x: x = 115 - y x = 115 - 65 x = 50 There are 50 large boxes.
I don’t know if this is right or not so, sorry if it’s wrong ;-;
1,2,3,4,5 = independent
c=1.25a = neither
$1.25, $2.50, $3.75, $5.00, $6.25 = dependent
Number of avocados = independent
Cost of avocados = dependent
If this is right then I’ll put the explanation in the comments, again sorry if it isn’t.
Answer:
5 and -6.
Step-by-step explanation:
When you add 5 and -6, you get -1. When they are multiplied, you get -30. I just did this by finding all of the factors that went into 30 and making one negative.
Answer:
Step-by-step explanation:
We have been given that the elevation of driskill mountain Louisiana is 163 meters above sea level. The death Valley has an elevation of -86 meters.
We can represent this information in an inequality as: . Our inequality means that the elevation of death valley is less than elevation of driskill mountain.
The answer is a, all rhombuses have equal sides, if they have equal sides then day have equal angles.
