2х2 – 3х – у = -5
—x + y = 5

Answer:

5 1/2

Step-by-step explanation:

The calories contained are from grams of carbohydrates and other ingredients

One gram of carbohydrate contains 4 calories

The equation 4c + 5 = 27 represents the relationship between these quantities.

1. 5 from the equation represent calories from other ingredients

2. Neither 8 nor 3 is the solution to the equation

4c + 5 = 27

When 8 is the solution

4(8)+5=27

32+5=27

37=27

When 3 is the solution

4(3)+5=27

12+5=27

17=27

Neither 8 nor 3 is the solution to the equation because 8 gives a higher calories in the granola bite and 3 gives a lower calories in the granola bite.

3. Solution to the equation

4c + 5 = 27

4c= 27-5

4c = 22

Divide both sides by 4

c=22/4

=5 2/4

=5 1/2

The solution to the equation is 5 1/2

Answer:

The second base of the trapezoid b2 is 2.5 inches

Step-by-step explanation:

Here, we want to calculate the second base of the trapezoid.

Mathematically, the area of a trapezoid can be given as;

A = 1/2(a + b) h

where a and b represents the parallel bases and h is the height of the trapezoid

so this, we have from the question

1/2(4.5 + b2) * 6 = 21

3(4.5 + b2) = 21

divide both sides by 3

4.5 + b2 = 7

b2 = 7-4.5

b2 = 2.5 inches

Answer:

20

Step-by-step explanation:

We can simplify 10/2 = 5

5 = n/4

Multiply each side by 4

5*4 = n/4*4

20 =n

Answer: n = 20

Explanation: To solve for n in this proportion,

we simply use the means-extremes property.

Since 10/2 = n/4, we know that the product of the extremes,

(10)(4), equals the product of the means, (2)(n).

So we know that (10)(4) or 40 equals (2)(n) or 2n.

Dividing both sides by 2, 20 = n.

Answer:

v= 15miles/hr (west)

Step-by-step explanation:

This is physics, so I'll use the most common formula. v=d/t. Convert 5 mins to an hour. 5min/60min = 1/12hr.

v= 1.25 miles / 1/12hr

v= 15miles/hr (west). Don't forget the right arrow on the v.

Answer:

15miles/hr (west)

Answer:

Lynne's social media account has 1,000 followers. Her followers are increasing by 100 per day. In the next 10 days her followers will reach to 2,000 followers.

Dan's social media account has 200 followers and his number of followers are doubled after every 2 days. This means he will have 6400 followers after 10 days.

Step-by-step explanation:

Dan's social media account is gaining speedy increase in followers as his followers are doubling every two days. Lynne's social media account is gaining 100 followers increase every day. This is slower than the follower that Dan is gaining.

Answer:

[tex]-0.04b^{19}[/tex]

Step-by-step explanation:

We have the expression [tex](-0.2b^6)^3\times 5b[/tex] and we want to rewrite/simplify this to a monomial (only one term).

First, let's expand. We can use the power of a product exponent property, where [tex](ab)^x=a^xb^x[/tex]

We have:

[tex](-0.2b^6)^3\times 5b[/tex]

Using the above property, this will be:

[tex]=(-0.2)^3(b^6)^3\times5b[/tex]

(-0.2) cubed is -0.008. So, this becomes:

[tex]=-0.008(b^6)^3\times 5b[/tex]

We can now use the power of a power property, where [tex](x^a)^b=x^{ab}[/tex].

Therefore, this will give us:

[tex]=-0.008b^{6\times 3}\times 5b[/tex]

Evaluate:

[tex]=-0.008b^{18}\times 5b[/tex]

Notice that 5b is the same as 5 times b to the first power. So:

[tex]=-0.008\times b^{18}\times5\times b^1[/tex]

We can rearrange this to get:

[tex]=-0.008\times 5\times b^{18}\times b^1[/tex]

When we multiply exponents with the same base, we will simply add the exponents. -0.008 times 5 is -0.04. Therefore, this yields:

[tex]=-0.04b^{18+1}\\=-0.04b^{19}[/tex]

Therefore, our final answer is [tex]-0.04b^{19}[/tex].

And this is indeed a monomial since this only has one term.

Answer: alternate exterior

Step-by-step explanation:

Solve

5x + 2x -6 = -2(x - 1)

7x - 6 = -2(x-1)

Distribute

7x - 6 = -2(x - 1)

7x - 6 = -2x + 2

Add 6 to each side

7x - 6 + 6 = -2x + 2 + 6

Simplify

7x = -2x + 8

x = 8/9

So your answer is B. I believe

5x + 2(x - 3) = -2(x - 1)

its 8/9

Answer:

Step-by-step explanation:

If Asia woke up by 5:45am and her bus regularly arrives at 6:15 am, the the total amount of time Asia needs to finish up to meet the bus is time within this interval of time i.e 30mintes.

Total time taken to dress up:

Time taken to throw an outfit = 5minutes

Time taken to do her hair and make up = 2(5) = 10 minutes

Time to walk to bus stop = 5+8 = 13minutes(8 minutes longer)

Total time she took to finish up and get to the bus = 5+10+13 = 28 minutes

Since the time used by Asia is less than the 30 minutes expected of her hence she will meet the bus

Answer:

She would be 3 minutes late.

Step-by-step explanation:

The time difference between 5:45 am and 6:15 am = 30 minutes

If it takes her 5 minutes to throw on an outfit = 5 minutes

A minimum of twice as long to do her hair and make-up = ≤ 5 × 2

≤ 10 minutes

Eight minutes longer than that to walk to the bus stop.

= 8 minutes longer than how long it takes her to do her hair and makeup

= 10 + 8

= 18 minutes

Total number of times it takes her to make it to the busstop

=( 5 + 10 + 18)minutes

= 33 minutes

Therefore, she will not make it because she would be 3 minutes late.

Answer:

The cost of one hosts is $5 and the coat of one geranium is $9

Step-by-step explanation:

Let the cost of one hosta be x

Let the cost of one geranium be y

If Totsakan spent $178 on 14 hostas and 12 geraniums, then the expression to represent this statement will be;

14x+12y = 178

7x+6y = 89 .... 1

Also if Lea spent $71 on 7 hostas and 4 geraniums, the the expression that represent the statement is;

7x+4y = 71..... 2

Subtract equation 1 from 2:

(7x-7x)+(6y-4y) =89-71

0+2y = 18

2y = 18

y = 18/2

y = 9

Substitute y = 9 into equation 1:

7x+6(9) = 89

7x +54 = 89

7x = 89-54

7x = 35

x = 35/7

x = 5

Therefore the cost of one hosts is $5 and the coat of one geranium is $9

Answer:

45 slices of turkey used

Step-by-step explanation:

In order to figure out this problem we first need to calculate the total amount of sandwiches that were ordered. Since 27 regular sandwiches were ordered and we know that three times as many customers ordered the regular sandwich as the large sandwich. Then we simply divide 27 by 3 to find out how many large sandwiches were ordered.

27 / 3 = 9 large sandwiches.

Now, assuming that each regular sandwich only takes one slice of turkey, we can multiply 9 by 2 since each large sandwich takes double the slices and add that to 27 to calculate the total number of slices used in all of the sandwiches for that day.

(9*2) + 27 = s

18 + 27 = s

45 = s

There were a total of 45 slices of turkey used.
