Answer:The cost to ship one ounce is $0.48 per ounce
Step-by-step explanation:
The total weight of the package that Julia shipped is 9.5 ounces. Julia pays $4.56 to ship a package that weighs 9.5 ounces. The cost to ship one ounce would be
4.56/9.5 = $0.48 per ounce
8x + 3y = 20.50
-
4x+5y=22.50
=
4x-2y=-2, so you have to divide each number by 2, then
2x-y=-1, so
-y=-1-2x /-1, y=1+2x, then replace it with one original equation like the first one for instance:
8x+3(1+2x)=20.50, then
8x+3+6x=20.50, then
14x=20.50-3
14x=17.5
x=1.25, then solve y:\
y=1+2*(1.25)
y=1+2.5
y=3.5,
So answer is x=1.25, and y=3.5
Answer:
Step-by-step explanation:
to find slope: the formula is:
(y2-y1) / (x2-x1)
in this case it is:
(-9-(-2)) / (-10-(-2))
-7/-8
and thats the slope (that was for question one, and also an example, now do the same for questions 2, 3 and 4!!
hope thsi helps!!
Answer:
part A: 3yx
Part B: (x+y)+z
C: 3xy-6x
Step-by-step explanation:
Commutative property: change the orders in which numbers are multiplied
associative: when all the integers are in addition you can add parentheses wherever u like
distributive: multiply the number just outside the parentheses with the every numbers inside the parentheses
Hope this heps!
Answer:
x = 3
Step-by-step explanation:
Hi there,
We know that the value of ∠ABD and ∠DBC are the same because BD bisects it. Therefore, we can set both of the angle values equal to each other to find the value of x.
9x = (8x + 3)
x = 3
Hope this answer helps. Feel free to ask questions. Cheers.
