1.Simplified each one 
2/5 (both divided by 7) ,  1/2 (divided by 21)
2.Make them into integer
(2/5 )*(2/2)=4/10    ,    (1/2)*(5/5)=5/10
Now the dominators are the same ,you can just compare the numerators. It is 4:5

Colin received a bonus check for 2,500$. He is going to deposit the money into his bank account that receives 5.5% simple intere
alex41 [277]
This is the concept of financial mathematics, the simple interest rate is given by:
S.I.=(PRT)/100
where:
P=principle=$2500
R=rate=5.5%
T=time=1 year
Hence;
S.I.=(5.5*2500.1)/100
=$137.5
Thus the total amount he had after 1 year will be:
2500+137.5
=$2,637.5

Can you solve this problem please​
Afina-wow [57]

Answer:

k = 11

Step-by-step explanation:

Given the points are collinear then the slopes between consecutive points are equal.

Using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (1, - 1)

m = \frac{-1-1}{1-5} = \frac{-2}{-4} = \frac{1}{2}

Repeat with another 2 points and equate to \frac{1}{2}

with (x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (k, 4)

m = \frac{4+1}{k-1} , then

\frac{5}{k-1} = \frac{1}{2} ( cross- multiply )

k - 1 = 10 ( add 1 to both sides )

k = 11
