⓵ If they delivered all 776 ounces that they needed to deliver :
45 boxes + 52 boxes = 776 ounces
97 boxes = 776 ounces
Which means that 97 boxes weight 776 ounces!
⓶ You have to do a cross product in order to find out the weight of a single box :
97 boxes → 776 ounces
1 box → × ounces
(776 x 1) ÷ 97 = ×
↓
(776) ÷ 97 = ×
↓
776 ÷ 97 = 8
Which means that × = 8 (× being the weight of a single box)!
So to answer your problem : "Write and solve an equation to find the weight of each cookie box”
↠ My equation was : × = (776 x 1) ÷ 97
↠ The weight of each cookie box :
8 ounces
I really hope this helped, if there’s anything let me know! ☻
1/2 y +6 = x
y=2 (x-6)
= 2x-12
f^-1 (x)= 2x-12
8/15 = 56/105
This may be solved using proportion.
a/b = c/d
ad = bc where cross products are equal.
a = 8
b = f
c = 56
d = 105
ad = bc
8*105 = f*56
840 = 56f
840/56 = 56f/56
f = 15
56 ÷ 7 = 8
105 ÷ 7 = 15
Obtuse because it only takes one obtuse angle to make an obtuse triangle
