Remember, you can do anything to an equation as long as you do it to both sides

assuming N=n

1n-3-4n=21
1n-4n-3=21
-3n-3=21
add 3 to both sides
-3n=24
divide both sides by -3
n=-8

Advocard [28]

Answer:

C

Step-by-step explanation:

(f + g)(x) = f(x) + g(x) , thus

f(x) + g(x)

= 2x + 1 + x² - 7 ← collect like terms

= x² + 2x - 6 → C

Convert 0.827 to a fraction or in simplest form
dangina [55]
<span>0.827 = 0.827 / 1


Numerator = 0.827 × 10 × 10 × 10 = 827
Denominator  = 1 × 10 × 10 × 10 = 1000

Numerator / Denominator = 827 / 1000

Simplifying our fraction

= 827/1000

= 827/1000</span>

Cathy is paid at a rate of K7.20 per hour for a basic hour-week of 70 hours. She is paid time-and-a-half for over-time during th
Levart [38]

Answer:

K1310.4

Step-by-step explanation:

Basic pay per hour = K7.20

Overtime pay during the week per hour = 1 1/2 * K7. 20 = K10.8

Weekends = 2 * K7.20 = K14.4

Basic hours per week = 70 hours

In a fortnight :

Basic hours = 70 * 2 = 140 hours :

Hence, Overtime during the week = (160 - 140) = 20 hours

Weekend hours = (4 +2) = 6 hours

Total earning :

(140 * 7.20) + (20 * 10.8) + (6 * 14.4)

1008 + 216 + 86.4

= K1310.4
