Using substitution:
13(y+6)-6y=22
13y+78-6y=22
7y+78=22
/// -78 -78
7y=-56
÷7 ÷7
y=-8
x=y+6
x=-8+6
x=-2
So, x equals -2 and y equals -8.
Answer:
Step-by-step explanation:
Start by writing these five numbers in just one format (improper fractions with denominator 10):
9/5 = 18/10, and
-2.5 = -25/10, and
-1.1 = -11/10, and
-4/5 = -8/10, and, finally
0.8 = 8/10
The smallest of these (the least) is -25/10, and
the largest is 18/10.
Arranged in ascending order, we have:
-25/10, -11/10, -8/10, 8/10, 18/10, or
-2.5, -1.1, -4/5, 0.8, 9/5
Answer:
25%
Step-by-step explanation:
profit percentage = (profit/cost price) * 100
selling price = 600
profit = 600 * 20/100 = 120
cost price = 600-120 =480
profit percentage = (120/480) * 100 = 25
27,491,739 times 93,792 is 2,578,505,184,288.
yes sure, i learned this before so
1. a. make a proportion here, of percentage.
if you cross multiply and divide you get 90%.
1. b. obviously the empty seats would be 10%.
2. a. proportion again,
cross multiply then divide you ge 15%
3. 30% in decimal form is 0.3. multiply it then to the total amount, so 0.3 x 15 = 4.5
