<h3>hello!</h3>

the "sum of" means we add.

So the sum of n and 12 means we add n and 12:-

n+12

12+n (both of these expressions mean the same thing)

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I'll comment and/or edit my answer :)

If the sum of four consecutive numbers is n, what is the first one?

serg [7]

$x - first\ number\\\\x,\ x+1,\ x+2,\ x+3-\text{four consecutive integers}\\\\\text{The equation:}\\\\x+(x+1)+(x+2)+(x+3)=n\\\\4x+6=n\ \ \ \ |-6\\\\4x=n-6\ \ \ \ \ |:4\\\\\boxed{x=\dfrac{n-6}{4}}$

$m, m+1,\ m+2,\ m+3,\ m+4,\ m+5,\ m+6-\text{seven consecutive numbers}\\\\\text{The sum}\\\\m+(m+1)+(m+2)+(m+3)+(m+4)+(m+5)+(m+6)=7m+21$

Answer:

(5, 2) & (-4, -9)

Step-by-step explanation:

Use the vertex form, y = a(x − h)² + k, to determine the values of a, h, and k

(h, k) = (5, 2)

(h, k) = (-4, -9)

Item 9 Find the annual interest rate. I=$562.50, P=$1500, t=5 yearsI=$562.50, P=$1500, t=5 years The annual interest rate is %.

Anton [14]

Hi there :-)
The formula of the simple interest is
I=prt
your question ask to find r which is interest rate you do that by dividing each side by (pt) to get
R=I÷pt
Now solve to get the interest rate
R=562.5÷(1,500×5)
R=0.075×100 multiply by 100 to get it as percentage
R=7.5%

Hope it helps:-)

Can some one help me with number six?

Elza [17]

What I do in my school is Part over a Whole equals % over 100.

So the whole is 80, the percent is 80% over 100. We need to find the part so we cross multiply. 80×80% is 1600. Divide that by 100 and u get 16 points.

HOPE THAT HELPS!
