Jane is saving to buy a cell phone. She is given a $100 gift to start and saves me

Dmitriy789 [7]

Answer:

See explanation

Step-by-step explanation:

Jane is given a $100 gift to start and saves $35 a month from her allowance.

After 1 month, Jane has saved $\$100+\$35=\$135;$
After 2 months, Jane has saved $\$100+2\cdot \$35=\$170;$
After three months, Jane has saved $\$100+3\cdot \$35=\$205;$
and so on

In general, after x months Jane has saved

$\$100+x\cdot \$35=\$(100+35x).$

This means that it makes sense to represent the relationship between the amount saved and the number of months with one constant rate (in this case the constant rate is 35). It makes sense because the amount of money increases by $35 each month. Since the amount of increase is constant, we get constant rate. Also the initial amount is known ($100), so there is a possibility to write the equation of linear function representing this situation.

What is the value of x?

kozerog [31]

Answer:

x = 35

Step-by-step explanation:

Since they are vertical angles, the angles are congruent and therefore you can set them equal to each other.

4x + 20 = 3x + 55

Have x on one side of the equation by subtracting 3x from both sides.

x + 20 = 55

Subtract 20 from both sides of the equation.

x = 35

to find the final cost of the shoes, the $15 coupon can be applied first and then the 20% discount, or the 20% discount can be a

guapka [62]

First apply 20% discount then applied $15 coupon combination gives better deal.

As given in the question,

Let final cost of the shoes be $100

First apply $15 coupon then applied 20% discount

100-15=$85

Now, 20% of 85= (20/100) × 85

=$17

Final price, 85 - 17 =$68

First apply 20% discount then applied $15 coupon

Now, 20% of 100= (20/100) × 100

=$20

100-20 = $80

Apply coupon $15

Final price, 80 - 15 =$65

Therefore, first apply 20% discount then applied $15 coupon combination gives better deal.

How do you solve 8a squared plus 2 = 634

Inga [223]

Answer:

a ≈ 8.9

Step-by-step explanation:

Set up the equation as so:

8a^2 + 2 = 634

First, subtract two from both sides:

8a^2 = 632

Then, divide by 8 to further isolate the variable.

a^2 = 79

To get rid of the squared, you have to take the square root of both sides. The square root of 79 is roughly 8.9. Ergo, a ≈ 8.9
