27+6(2*2-1)4*2-5
2*2=4
27+6(4-1)4*2-5
4-1=3
27+6(3)4*2-5
6*3=18
27+(18)4*2-5
18*4=72
27+(72)*2-5
72*2=144
27+(144)-5
27+144+171
171-5=166
So the answer is 166.
Answer:A
Step-by-step explanation: If you plug in 1 for n then 1-1=0 8x4=32x0=0
If you plug in 2 for n then 2-1=1 8x4=32x1=32 if you plug in 3 for n then 3-1=2 8x4=32x2=64
Answer:
n=5
Step-by-step explanation:
4 + 7n - 42 = -3
+42 +42
4 + 7n = 39
-4 -4
7n = 35
÷7 ÷7
n = 5
Answer:
( 35+9=44)
Step-by-step explanation:
About 400 zebras live at the game reserve.
The proportion would be
30/150 = 80/x
This is because 30 zebras are tagged out of 150 in one area. We know that they tagged 80 total zebras out of x total zebras.
To solve this, cross multiply:
x*30 = 150*80
30x = 12000
Divide both sides by 30:
30x/30 = 12000/30
x = 400
