While you cannot solve 946x+642y=911 for numerical values of x and y, you can indeed solve 946x+642y=911 first for x and then for y:
-911 - 642y
For x: 946x+642y=911 becomes 946x = 911 - 642y, or x = ------------------
946
911-946x
For y: 946x+642y=911 becomes 642y = 911-946x, or y = ---------------

id a is d than c is b butvthey arent equal so the answe is a
Answer:
1759.52cm^3
Step-by-step explanation:
Given data
Cylinder E
h = 30 cm and
r = 4 cm
The expression for the volume is
V= πr^2h
V= 3.142*4^2*30
V= 3.142*16*30
V=1508.16 cm^3
Cylinder F
h=5 cm
r = 4 cm
The expression for the volume is
V= πr^2h
V= 3.142*4^2*5
V= 3.142*16*5
V=251.36 cm^3
Hence the total volume is
=251.36+1508.16
= 1759.52cm^3
Answer:
12.124-3
Step-by-step explanation:
Answer:
12.5% decrease
Step-by-step explanation:
Let X be the initial value
75% increase is 175% of X
= 1.75X
50% decrease = 0.5
0.5(1.75X)
0.875X (less than X, so decrease)
87.5% of X
100 - 87.5 = 12.5% decrease
