Answer:

Step-by-step explanation:

Each day, the same amount is spent.

Let X be the initial amount at the beginning of the week, T be the amount spent per day.

i. X - 2T = $12.1

ii. $12.1 - 3T = $2.5

Solving ii,

3T = 12.1 - 2.5

T = 9.6/3

= 3.2

Inputting this value in i,

X = 12.1 + (3.2 * 2)

= $18.5

In slope- intercept form, y = mx + c

Slope,m = y2 - y1/x2 - x1

= 2.5 - 12.1/5 - 2

= $-3.2 /day

y = -3.2x + 18.5.

Answer:

The total allowance is $18.5, and the amount spent daily is $3.2

Step-by-step explanation:

let T and x represent the total allowance and the amount spent daily respectively.

It was started that the amount remaining after 2 days is $12.10 , which implies the person has spend an equal amount for 2 days

T - 2x =12.10       (equation 1)

It was started that the amount remaining after 5 days is $2.50  , which also implies the person has spend an equal amount for 5 days

T - 5x =2.5       (equation 2)

subtract equation 2 from 1

T - 2x -( T - 5x ) = 12.10 -2.5

T - 2x -T + 5x = 9.6

3x =9.6

Divide both side by 3

x = 9.6/3 =3.2

from equation 1

T - 2x =12.10  

T = 12.10 + 2x = 12.10 + 2*3.2

= 12.10 + 6.4 = 18.5

Shane and Karen want to measure the length of a soccer field. Should they use centimeters or meters to measure it? Explain.
Ber [7]

Shane and Karen want to measure the length of a soccer field. Length can be measured in different units such as cm, m ,km , yards etc. The question is asking us to select between two units cm or meters which will be more appropriate to measure the field.

To measure the field a larger unit is required. Meter is a bigger unit than centimeter.Centimeter is not the correct unit to measure the length of soccer field.

Shane and Karen should use meters to measure the soccer field.

2(x+2) - 3(x-3)=x+7​
babunello [35]

Step-by-step explanation:

Let's solve your equation step-by-step.

2(x+2)−3(x−3)=x+7

Step 1: Simplify both sides of the equation.

2(x+2)−3(x−3)=x+7

(2)(x)+(2)(2)+(−3)(x)+(−3)(−3)=x+7(Distribute)

2x+4+−3x+9=x+7

(2x+−3x)+(4+9)=x+7(Combine Like Terms)

−x+13=x+7

−x+13=x+7

Step 2: Subtract x from both sides.

−x+13−x=x+7−x

−2x+13=7

Step 3: Subtract 13 from both sides.

−2x+13−13=7−13

−2x=−6

Step 4: Divide both sides by -2.

−2x

−2

=

−6

−2

x=3

Answer:

x=3
