Answer:

4 packs of medium cups and 6 packs of large cups

Step-by-step explanation:

1.80x + 2.40y = 21.60

1.80(4) + 2.40(6) = 21.60

7.2 + 14.4 = 21.60

21.60 = 21.60

Answer:

Ivy bought 4 packs of medium cups, and 6 packs of large cups.

Step-by-step explanation:

To solve this problem, we will have to use a system of equations. Our first equation will represent the cups, and our second equation the costs.

Let [tex]m[/tex] equal medium cups.

Let [tex]l[/tex] equal large cups.

[tex]m+l=10[/tex]

[tex]1.80m+2.40l=21.60[/tex]

Let's use substitution to solve this system.

Subtract [tex]l[/tex] from both sides of the first equation:

[tex]m=10-l[/tex]

Let's substitute [tex]10-l[/tex] into the second equation for [tex]m[/tex]:

[tex]1.80(10-l)+2.40l=21.60[/tex]

Distribute [tex]1.80[/tex] into [tex](10-l)[/tex]:

[tex]18-1.80l+2.40l=21.60[/tex]

Combine like terms:

[tex]18+0.6l=21.60[/tex]

Subtract [tex]18[/tex] from both sides of the equation:

[tex]-0.6l=3.60[/tex]

Divide by the coefficient of [tex]l[/tex], which is [tex]0.6[/tex]:

[tex]l=6[/tex]

Ivy bought 6 packs of large cups.

_

Let's substitute [tex]6[/tex] into the first equation to find the number of medium cup packs:

[tex]m+6=10[/tex]

Subtract [tex]6[/tex] from both sides of the equation:

[tex]m=4[/tex]

Ivy bought 4 packs of medium cups.

_

We can check our work 2 ways; by substituting our solved values into the initial equations.

1st Equation Check:

[tex](4)+(6)=10[/tex]

[tex]10=10[/tex]

2nd Equation Check:

[tex]1.80(4)+2.40(6)=21.60[/tex]

[tex]7.2+14.4=21.60[/tex]

[tex]21.60=21.60[/tex]

Answer:

x inntercept is 2

Step-by-step explanation:

Answer: B

Step-by-step explanation:

The simplified equation that is equivalent to the given equation is 16x - 5 = -47. The correct answer is option B.

The equation is given as follows:

15x - 5 + x = -47

A solution to an equation, as we know, is a variable value that, when substituted into the equation, provides a true claim.

To simplify the equation 15x - 5 + x = -47, we can combine the like terms on the left side of the equation.

Combining the terms with 'x', we have:

15x + x - 5 = -47

16x - 5 = -47

Therefore, the simplified equation that is equivalent to the given equation is 16x - 5 = -47.

Answer:

D - cos(157)

Step-by-step explanation:

Cos sum angle identity

cos(A+B) = cosAcosB - sinAsinB

103+54=157

The correct answer to the question is Cos 157

There are two ways to solve this question:

Evaluate: Cos103Cos54 – Sine103Sine54

This can be obtained as follow:

Cos103Cos54 – Sine103Sine54

= –0.1322 – 0.7883

Next, we shall evaluate each option given in the question to see which will be equivalent to –0.9205. This is illustrated below:

Sine 49 = 0.7547

Cos 49 = 0.6561

Sine 157 = 0.3907

From the above evaluation, we can see that Cos 157 is equivalent to Cos103Cos54 – Sine103Sine54

Thus, Cos 157 is the correct answer to the question.

Again, we can apply the addition formula from trigonometry.

Cos (A – B) = CosACosB + SineASineB

Cos (A + B) = CosACosB – SineASineB

Sine (A + B) = SineACosB + SineBCosA

Sine (A – B) = SineACosB – SineBCosA

Comparing

Cos103Cos54 – Sine103Sine54 with the formula given above, it is very clear that:

Cos103Cos54 – Sine103Sine54 = Cos 157

Cos103Cos54 – Sine103Sine54 = –0.9205

Therefore, Cos 157 remains the correct answer to the question.

_________________________________

Step (1)

First we find the diameter ((h)) of the rectangle on the floor using the Pythagorean theorem.

So we have :

[tex] {h}^{2} = {a}^{2} + {b}^{2} [/tex]

[tex] {h}^{2} = 64 + 9 [/tex]

[tex] {h}^{2} = 73 [/tex]

[tex]h = \sqrt{73} [/tex]

Step (2)

Now we another using of Pythagorean theorem for finding d :

[tex] {d}^{2} = {h}^{2} + {c}^{2} [/tex]

[tex] {d}^{2} = 73 + 16 [/tex]

[tex] {d}^{2} = 89 [/tex]

Answer:

y = 5x^3

Step-by-step explanation:

If there is an exponent other than 1 on a variable, then it is not linear.

Answer: y = 5x^3 since the exponent on x is 3.

Answer:

y = 1/2x -.5

Step-by-step explanation:

We know that is the line is parallel to the equation then the slopes are going to be the same we just have to find the a different y-intercept.

It's a simple as this just plug the points into the equation you have like this.

(-7,-4) (PLUG IN)

-4 = 1/2(-7) +b (I do plus be so we can get another y intercept)

-4 = -3.5 + b (add 3.5 on each side)

-.5 = b

the equation parallel to the first one is...

y = 1/2x -.5

If this was helpful please mark brainliest, have a great day!

I have no idea whether those numbers are correct, and I'm not gonna bother looking them up.

But you gave us a speed and a distance, and you asked for a time.

We can just go ahead and use the formula:  Time = (distance) / (speed) .

IF your numbers are true, then

Time = (distance) / (speed)

Time = (3.55 x 10⁹ mi) / (1.25 x 10⁷ mi/min)

Time =  (3.55 x 10⁹ / 1.25 x 10⁷) minutes

Time =  2.84 x 10² minutes

Time = 284 minutes

Time = 4 hours 44 minutes
