Answer:
B and E
Step-by-step explanation:
A. 8x = 2
8(4) = 2
32 = 2
B. 19 + x = 23
19 + 4 = 23
23 = 23
C. 40/x = 5
40/4 = 5
10 = 5
D. -3x = 12
-3(4) = 12
-12 = 12
E. x - x - x - x = -8
4 - 4 - 4 - 4 = -8
0 - 4 - 4 = -8
-4 - 4 = -8
-4 + (-4) = -8
-8 = -8
Answer:
Hey!
To start this problem, we'll most likely need a calculator. Handling
can get a little messy, and tricky.
(also note that "pie" is a food, the mathematical term
, is pronounced "pie", but spelled "pi.")
Anyway, multiplying 3.14159265359..... (
)
160 = 502.654824574...... going on and on.
In general, these types of problems are better for a calculator if you want an exact answer. Otherwise, just resort to estimation.
is pretty close to 3.14.
160
3.14 = 502.4, which is decently close to our other answer.
Hope this helps!

answer for 9 is 6cm not sure about 10
Both because 2 x 3 is 6 2x2 is 4 and you get 4/6 so both have the same amount of vegetables
5*2x is 10x
5*3y is 15y
5*5z is 25z
