Answer: b=27
Step-by-step explanation: Add 119+34 and you get 153. Subtract 153 from 180 and you get 27. Hope this helps.
If $4000 is the principal, compounded annually at 6%per annum for five years, then-
Amount=principal *(1+rate/100)^5
=4000*(1+6/100)^5
=4000*(53/100)^5
=5352.90
Therefore, Compound Interest =5352.90-4000
=$1352.90
Please recheck the calculation.
4x - 5y = -15
y = -3x + 22
Plug in your y= equation into the y variable in the other equation
4x - 5 (y) = -15
^^
y = (-3x + 22) = -15
4x - 5 (-3x + 22) = -15
Distribute
4x + 15x - 110 = -15
Combine like terms and add 110 over to -15
19x = 95
Then, divide the whole equation by 19
x = 5
Then, plug in your x into your y= equation
y = -3 (5) + 22
y = -15 + 22
y = 7
<em><u>x = 5</u></em>
<em><u>y = 7</u></em>
<em><u>(5, 7)</u></em>
Answer:
Randy just added up the numbers on the numerator and denominator.
This is incorrect.
<u>Correct way of adding the fractions given below:</u>
- 7/8 + 9/15 = ⇒ Simplify the second equation, divide by 3)
- 7/8 + 3/5 =
- 5*7/5*8 + 8*3/8*5 = ⇒ Bring both fractions to common denominator of 40
- 35/40 + 24/40 = ⇒ Add up the numbers in the nominator
- 54/40 = ⇒ Simplify by dividing by 2
- 27/20 =
- 1 7/20 ⇒ Convert to mixed fraction
(8x)^2 = 1
64 x^2 = 1
x^2 = 1/64
x = 1/8
Answer
The positive value of x that makes the equation true is x = 1/8
