Answer:

Therefore, the correct option is;

x = 2

Step-by-step explanation:

Let x represent the number of tiles, and let 1 represent the positive 1 tiles

Let the and operator represent addition we have;

3 × x + 8 × 1 = 4 × x + 6 × 1

We simplify as follows;

3·x + 8 = 4·x + 6

We move and place like terms together as follows;

4·x - 3·x = 8 - 6

From which we have;

x = 2

Therefore, the correct option is x = 2

Answer: 26-5

Step-by-step explanation:

literally you take 5 aways from 26

Answer:

1 and 9/20

Step-by-step explanation:

add your fractions together 7/10 + 3/4

make them have the same denom 14/20 + 15/20

so its 29/20

to get the mixed fraction, divide 29/20 to get 1.45. The 1 is your whole number. Subtract 20 from 29 to get 9, which is what is remaining, and will go over 20.

the answer is 1 and 9/20

work:

7/10km = 14/20km

3/4km = 15/20km

15/20+14/20=29/20km

29/20 as a mixed number is 1 and 9/20.

Answer:

120 degrees

Step-by-step explanation:

To find m<1 we must first find the other angles.

First, find m<CDB. To do this use the complementary angle 130. So m<CDB=180-130, which means m<CDB=50.

Then find m<2, to do this remember that all triangles equal 180. So to find m<2 solve the equation m<2=180-(70+50), which equals 60 degrees.

Finally find m<1 the same way you found m<CDB, using the complementary angle 2. m<2=180-60, therefore m<1=120.

Answer:

120

Step-by-step explanation:

A: an exterior angle is supplementary to the adjacent interior angle.

The true statement is an exterior angle is supplementary to the adjacent interior angle.

Two angles are called supplementary when their measures add up to 180 degrees.

We know,

A triangle's angles sum up to 180 degrees.

In the same way, adjacent angles add up to 180 degrees.

According to the preceding statements:

An outside angle is added to the adjacent interior angle to make a total of 180 degrees.

As a result, the correct statement about the interior and exterior angles of a triangle.

Answer:

a) 37 + 42 =79

=7/100 x 79

=553/100

=5.53

Isaac's total bill = 79 + 5.53 = $84.53

b) 25/100 x 79

= 19.75

= 79 - 19.75

= $59.25 (before tax)

7/100 x 59.25

= 414.75/100

= 4.15

= 59.25 + 4.15

= $63.4 (after adding tax)

Step-by-step explanation:First we have to take out the percentage of discount and minus it from the total cost . To find the discounted price with tax, we have to take out the percentage of the tax from the discounted amount and add it to the discounted amount to get the total cost.

Answer:

Isaac paid $84.53

Step-by-step explanation:

37+42=79.00

79.00* .07=5.53

Given Eq:

Solving this:

Squaring both sides,

➝ x + 3 = (x - 3)²

➝ x + 3 = x² - 6x + 9

Now shifting RHS to LHS,

➝ x + 3 - x² + 6x - 9 = 0

➝ -x² + 7x - 6 = 0

➝ x² - 7x + 6 = 0

Now finding the values of x by middle term factorisation,

➝ x² - 6x - x + 6 = 0

➝ x(x - 6) - 1(x - 6) = 0

➝ (x - 1)(x - 6) = 0

➝ x = 1 or 6.

But here, you can see, x = 1 is not a solution to the original equation because when we say about square roots, value can't be negative.

Step-by-step explanation:

I took the quiz

f(t) = 3.7t + 21

where t is the time in months

f = 3.7t /t + 21 / t

f = 3.7 + 21/t

The puppy's future weight in pounds as a function of time in months can be represented by f = 3.7 + 21/t.

Function is a type of relation, or rule, that maps one input to specific single output.

Given that veterinarian uses the function f(t) =3.7t +21

Thus, f(t) = 3.7t + 21 , where t is the time in months

To estimate a puppy's future weight in pounds as a function of time in months​, we have to divide by time t.

f = 3.7t /t + 21 / t

f = 3.7 + 21/t

Hence, the puppy's future weight in pounds as a function of time in months can be represented by f = 3.7 + 21/t.

Answer:

2/3y

Step-by-step explanation:

If the class usually has y students and has 2/3 today, it can be represented by 2/3y.

Since multiplying a number or variable by 2/3 makes it 2/3 of the amount, 2/3y will represent the people in the class.

So, in terms of y, 2/3y represents the number of students in class today.

Jada plans to serve milk and healthy cookies for a book club meeting. She is preparing 12 ounces of milk and 4 cookies per person. Including herself, there are 15 people in the club. A package of cookies contains 24 cookies and costs $4.50. A 1-gallon jug of milk contains 128 ounces and costs $3. Let represent number of people in the club, represent the ounces of milk, represent the number of cookies and represent Jada's budget in dollars. Select all of the equations that could represent the quantities and constraints in this situation.

Step-by-step explanation:

Jada plans to serve milk and healthy cookies for a book club meeting

She is preparing 12 ounces of milk and 4 cookies per person

There are 15 people in the club

A package of cookies contains 24 cookies and costs $4.50

A 1-gallon jug of milk contains 128 ounces and costs $3

Let us represents number of people in the club by n

The the ounces of milk = m

The number of cookies = c

Jada's budget in dollars = d

y = 12(15)

She is preparing 4 cookies per person

4n = c

Since A package of cookies contains 24 cookies

She needs = 15 × 4 = 60 cookies

60 ÷ 24 = 2.5

Hence, approximately, she has to buy 3 packages of cookies

She needs = 15 × 12 = 180 ounces of milk

A 1-gallon jug of milk contains 128 ounces

180 ÷ 128 = 1.406

She needs to buy 2 A 1-gallon jug of milk

Note that: from the question

The cost of each jug of milk is $3

The cost of each package of cookies is $4.50

b represents Jada's budget in dollars

b = 2(3) + 3(4.50)
