Answer:

6.5 weeks without parental help, 3.5 weeks with help from your parents.

Step-by-step explanation:

The Equation is:

Y = 20x

Y = Starting price for bikes

X = # of weeks

Therefore:

$130 = 20x

This can be simplified by solving for x

x = 130/20

x = 6.5 weeks

If your parents gave you $60 to help buy the bike the equation would be written as:

Y = 20x + 60

$130 = 20x + 60

Subtract 60 from both sides to get:

$70 = 20x

Solve for x

x = 70/20

x = 3.5 weeks

The school store sells binders for $5 and notebooks for $4. The store needs to sell $80 worth of these two items combined each w

lorasvet [3.4K]

Answer:

Step-by-step explanation:

Step one:

given

let binders be x

and notebooks be y

let the total sale be T

the cost of binder is $5 each

the cost of notebook is $4 each.

the total sales expected is $80

step two:

the linear model for the total sales is given as

T=x+y

using the given data, the situation can be represented linearly as

80=5x+4y

Therefore the linear expression for the total sale is 80=5x+4y

kari74 [83]

21 cars, 32 motorcycles.
create a system of equations using x for cars and y for motorcycles.
$\left \{ {{x+y=53} \atop {4x+2y=148}} \right.$
multiply the top equation by 2 to prepare for elimination method
$\left \{ {{2x+2y=106} \atop {4x+2y=148}} \right.$
subtract terms
$\left \{ {{2x+2y=106} \atop {-4x-2y=-148}} \right. = (-2x = -42)$
divide both sides by negative 2 to solve for x
x =21
plug in x into original equation to solve for y.
21 + y = 53
subtract both sides by 21
y=32

rewrite f(x)=x^2+8x-20 in the form that would most easily help you identify the zeros of the function

Snowcat [4.5K]

Answer:

f(x) = (x-2) (x+10)

Step-by-step explanation:

f(x)=x^2+8x-20

Factor the right hand side

What 2 numbers multiply to -20 and add to 8

-2 * 10 = -20

-2 + 10 = 8

f(x) = (x-2) (x+10)

Then we can use the zero product property to help us to find the zero's

Assume you have a balance of $1,900 on a credit card.

dimaraw [331]

principal=$1900

rate =13.6 %

simple interest= $35

Time=?

SIMPLE INTEREST ={PRINCIPAL×RATE×TIME}/{100}

$35= ${$1900 ×13.6× TIME}{100} /$

$35×100=25840× TIME

TIME= $\bold\frac{ 3500}{25840}$

TIME= $700/5168$

S and Tare mutually<br> exclusive events. Find P(sort)<br> P(S) = 12% P(T) =27%

mario62 [17]

The value of the probability P(S or T) is 39%

<h3>How to determine the probability?</h3>

The probability values are given as:

P(S) = 12% P(T) =27%

For mutually exclusive events,

P(S or T) = P(S) + P(T)

This gives

P(S or T) = 12% + 27%

Evaluate the sum

P(S or T) = 39%

Hence, the value of the probability P(S or T) is 39%
