Answer:
N= -8
Step-by-step explanation:
you will add 10and 6 to get 16
then add 8 to each side to cancel out. 16+8 will give you 24. now subtract the 8 off of in onto 5n
5-8 will give you -3. Now you need to divide -3 off of N on both sides so it cancels. -3÷-3=N....24÷-3=-8. Giving you N=-8
Answer:
79
Step-by-step explanation:
Let the original number be x.
x/2 = 39.5
x = 39.5 × 2
x = 79
The answer is the 5th one
let the numbers be x and y
x + y = 1600 ----*
12%x = 20%y
0.12x = 0.2y
y = <u>0</u><u>.</u><u>1</u><u>2</u><u>x</u>
0.2
y = 0.6x
substitute in * eqn
x + 0.6x = 1600
1.6x = 1600
x = 1000
then,
y = 0.6*1000
y = 600
the numbers are 1000 and 600
The answer is a enlargement
