Answers

Answer 1

Answer: Normally you would put the numbers least to greatest and the number in the middle would be the median.
But in this case 2 numbers, 2.99 and 3.89 are in the middle.
In this case the mean of the two middle numbers is the median.

Solve the Systems of equations algebraically 4x+5y=15
-4x+6y+7

Answers
A- (5/4, 2)
B- (2, 5/4)
C- (4/5,2)
D (2, 4/5)

Answers

STEP 1:
4x + 5y= 15
-4x + 6y= 7
add the two above equations; the x term cancels out; solve for y

11y= 22
divide both sides by 11

y= 2

STEP 2:
substitute the y value in step 1 into either original equation

4x + 5y= 15
4x + 5(2)= 15

4x + 10= 15
subtract 10 from both sides

4x= 5
divide both sides by 4

x= 5/4

ANSWER: (A) x= 5/4, y= 2 or (5/4, 2)

If 120% of a is equal to 80% of b, then what is the value of a b in terms of b

Answers

If you would like to know what is the value of a b in terms of b, you can calculate this using the following steps:

120% of a = 80% of b
120/100 * a = 80/100 * b /*100
120 * a = 80 * b /120
a = 80 / 120 * b
a = 2/3 * b

The correct result would be a = 2/3 * b.

120% = x 1.2

80% = x 0.8

$1.2a=0.8b \n \n a= (0.8)/(1.2)b \n \n \boxed{a= (2)/(3)b }$
