Answer:

35$

Step-by-step explanation:

Let the shirt be = X

And the tie =Y

X + Y= 48$

X = 22 + Y (The shirt costs $22 more than the tie)

22 + 2y = 48

2y = 26

y = 13

X= 48 – 13

X = 35

therefore, the cost of the shirt is $35

and the cost of the tie is $13

Gavin likes biking. This week his goal is to bike about 65 total miles over four days. Each day he wants to ride 1.5 times as fa

IRISSAK [1]

Step-by-step explanation:

let the first-day ride be x

Then the second-day ride will be =1.5 x

The third-day ride will be=1.5(1.5x)

The Fourth-day ride will be=1.5*1.5(1.5x)

hence for the four days the distance covered is

65=x+1.5x+1.5*1.5x+1.5*1.5*1.5x

65=x+1.5x+2.25x+3.375x

65=8.125x

divide both sides by 8.125 we have

x=65/8.125

x=8mile

the first-day ride be x=8miles

the second-day ride will be =1.5 x =1.5*8= 12miles

The third-day ride will be=1.5(1.5x) = 18miles

The Fourth-day ride will be=1.5*1.5(1.5x) = 27miles

Algebraic Woru

mafiozo [28]

The right answer is Option D.

Step-by-step explanation:

Let,

Kyle's money = x

Hayden's money = y

Jeremy's money = z

According to statements;

Kyle has three times as much money in his savings account as Hayden.

x = 3y Eqn 1

Hayden has twice as much money in his savings account as Jeremy.

z = 2y Eqn 2

Combined Kyle, Hayden, and Jeremy have a total of $612.

x+y+z=612 Eqn 3

Putting value of x and z from Eqn 1 and 2 in Eqn 3

$3y+y+2y=612\\6y=612$

Dividing both sides by 6

$\frac{6y}{6}=\frac{612}{6}\\y=102$

Putting in Eqn 1;

$x=3(102)\\x=306$

Kyle has $306 in his account.

The right answer is Option D.

Given the geometric sequence where a_1 = 3 and r = √2 find a_9

sesenic [268]

To find n-therm of a geometric sequence, we are going to use the formula $a_{n} =a _{1} r^{n-1}$
where:
$a_{n}$ is the term we are looking for
$a _{1}$ is the first term
$r$ is the ratio
$n$ is the position of the number in the sequence

From the question we now that $a _{1} =3$ , $r= \sqrt{2}$ , and $n=9$ . Lets replace those values into our formula to get:
$a _{9} =3( \sqrt{2} )^{9-1}$
$a_{9} =3 \sqrt{2} ^{8}$
$a_{9} =48$

We can conclude that in our geometric sequence $a_{9} =48$ ; therefore, the answer is A.
