A) is right
b) just subtract ljm and kjm so 145-48 = 92°
c) 9x-25=7x+7 so here you put npq=mpq+mpn and you combine terms so it's now 2x=32 then divide by 2 on both sides and x= 16
now you just plug it into 3x-5 and you get 43°
A and C

Answer:
544
Step-by-step explanation:
The ratios of cartons are ...
B : P = 2 : 1
S : L = 2 : 1
L : B = 2 : 1
Combining these into a single set of ratios, we have ...
S : L : B : P = 8 : 4 : 2 : 1
Then the proportion of the order that is strawberry is ...
8/(8+4+2+1) = 8/15
and the number of strawberry cartons is ...
(8/15)·1020 = 544
The store ordered 544 cartons of strawberry yogurt.
Step-by-step explanation:
A1=8
A2=A1+5 plug 8 into A1 here. After getting the value, put into next equation. And repeat until you get A5
A3=A2+5
A4=A3+5
A5=A4+5
