Imagine telling a friend about your favorite coffee and donut shop. Your friend asks how much it charges for a cup of coffee and a doughnut. While you can't remember how much each one costs individually, you do remember that's the last time you ordered one coffee and two donuts, your bill was $7.00. And today, when you bought two coffees and three Donuts, your bill came to $12.00.

Write a system of linear equations to represent the above situation.

Answers

Answer 1

Answer:

c + 2d = $7.00

2c + 3d = $12.00

Step-by-step explanation:

Hello!

Let:

c = # of coffeesd = # of donuts

1 coffee and 2 donuts cost $7.00

This can be repesented by 1c + 2d = $7.00, or c + 2d = $7.00

2 coffees and 3 donuts cost $12.00

This can be represented by 2c + 3d = $12.00

So, the system is :

c + 2d = $7.00

2c + 3d = $12.00

The two rules are :-

15 - 10(n - 1)

25 - 10n

Answer:

25 - 10n15 - 10(n - 1)

Explanation:

sequence: 15, 5, -5, -15, -25

solve:

1st rule 25 - 10n:

25 - 10(0) = 15

25 - 10(2) = 5

25 - 10(3) = -5

25 - 10(4) = -15

25 - 10(5) = -25

second rule using 15 - 10(n - 1):

15 - 10(1 - 1) = 15

15 - 10(2 - 1) = 5

15 - 10(3 - 1) = -5

15 - 10(4 - 1) = -15

15 - 10(5 - 1) = -25

Answers

Answer:

simplified: xy²value: 4

Step-by-step explanation:

The polynomial is simplified by combining like terms. Like terms are identified more easily if the variables in each term are written in the same order. We usually like to use alphabetical order. Two of the like terms have opposite coefficients, so they cancel. The result is ...

  (3 1/2 -2 1/2)xy² +(-2 4/5 +2 4/5)x²y

  = xy² . . . . simplified expression

For x = 1, y = -2, the value of the expression is ...

construct a quadratic equation whose root are 2-√3 and 2+√3​

Answers

Step-by-step explanation:

A quadratic equation can be constructed from their roots,

[tex](x - p)(x - q)[/tex]

where p and q are the roots.

Here the roots are

[tex]2 - \sqrt{3} [/tex]

and

[tex]2 + \sqrt{3} [/tex]

So we have

[tex](x - (2 - \sqrt{3} ))(x - (2 + \sqrt{3} ))[/tex]

[tex] {x}^{2} - 2x - x \sqrt{3} - 2x + x \sqrt{3} + 4 - 3[/tex]

[tex] {x}^{2} - 4x + 1 = 0[/tex]

So our answer is x^2

[tex] {x}^{2} - 4x + 1 = 0[/tex]

Which choice is equivalent to the expression below?
5^9.969

A. 59+9/10 + 9/10 + 6/1000
B. 59 +59/10 + 66/100
C. 59. 59/10. 56/100 . 59/1000
D. 59.596/10.59/100

Answers

Answer: Choice C

==================================================

Explanation:

We can rewrite the exponent 9.969 as 9 + 0.9 + 0.06 + 0.009

Then convert each decimal to a fraction

0.9 = 9/100.06 = 6/1000.009 = 9/1000

Your teacher is choosing not to reduce any of these fractions.

Then you'll use this rule [tex]a^{b+c} = a^b*a^c[/tex] to break up the exponent into the pieces mentioned.

So,

[tex]5^{9.969} = 5^{9 + 0.9+0.06+0.009}\\\\5^{9.969} = 5^{9 + 9/10+6/100+9/1000}\\\\5^{9.969} = 5^{9}\cdot 5^{9/10}\cdot 5^{6/100}\cdot 5^{9/1000}\\\\[/tex]

john paid $9.25 for a number of packets of instant noodles costing $1.85 for 5. How many packets of noodles did john buy? If he were to buy 40 packets of the same noodles, would $15 be enough to pay for them?

Answers

Every 5 packets cost $1.85

John can afford 9.25 : 1.85 = 5 (times)

So, John bought 5 x 5 = 25 packets of noodles.

If he were to buy 40 packets, he would've had to pay 40 : 25 = 1.6 times more money.

So, he would've had to pay : 9.25 x 1.6 = 14.8 (dollars)

Since 14.8 < 15, $15 would be enough to pay for 40 packets of instant noodles.

You have $12, and need at least x more dollars to spend $30 total. So the inequality is 12 + x ≥ 30, where x is the number of dollars needed to get free delivery. To solve for x, subtract 12 from each side of the sign. x ≥ 30 - 12, x ≥ 18. You must spend at least 18 more dollars to qualify for free delivery.
