Answer:

<h3>\boxed{ \bold{ \sf{ \boxed{ p = 3}}}}</h3>

\boxed{ \bold{ \sf{ \boxed{n = 1}}}}

Step-by-step explanation:

1. \sf{7p - p = 18}

Collect like terms

⇒\sf{6p = 18}

Divide both sides of the equation by 6

⇒\sf{ \frac{6p}{6}  =  \frac{18}{6} }

Calculate

⇒\sf{p = 3}

2. \sf{ - 5n - 4n =  - 9}

Collect like terms

⇒\sf{ - 9n =  - 9}

Divide both sides of the equation by -9

⇒\sf{ \frac{ - 9n}{ - 9}  =  \frac{ - 9}{ - 9} }

Calculate

⇒\sf{n = 1}

Hope I helped!

Best regards!!

serious [3.7K]

Answer:

3.2%

Step-by-step explanation:

-Let r be the simple interest rate per annum.

-Given the total amount after 1 year is 1857.60, the initial amount is 1800

#We use the simple interest formula to find the rate of interest:

Interest=Final\ Amount-Initial\ Amount\\\\=1857.60-1800\\\\=57.60\\\\I=Prt\\\\57.60=1800\times r\times 1\\\\r=\frac{57.60}{1800}\\\\=0.032\\\\=3.2\%

Hence, the annual interest rate on the deposit is 3.2%

Need help with the problem in the photo.
Simora [160]

Answer:

43

Step-by-step explanation:

The angle, 3x + 14 and the other angle 143 are alternate exterior angles. Alternate exterior angles are congruent to each other if the two lines are parallel. So in this case both the angles are considered congruent from the question assuming that they are congruent.

143 = 3x + 14

129 = 3x

x = 43
