Step-by-step explanation:

(4 + [tex]\frac{2}{9}[/tex] ) = (6 + [tex]\frac{1}{3}[/tex] ) b       Original equation

4 + [tex]\frac{2}{9}[/tex] = 6b + [tex]\frac{1}{3}[/tex]b            Distributive property

4 [tex]\frac{2}{9}[/tex] = 6[tex]\frac{1}{3}[/tex] b                     Simplification

[tex]\frac{38}{9}[/tex] = [tex]\frac{19}{3}[/tex]b                        Extra simplification

Answer:

Let's define the variables:

D = arrangements of daisies that he buys

R = arrangements of roses that he buys.

Each arrangement of daisies costs $4.25, then for D of them, the total cost is:

D*$4.25

And for the roses, the cost of each one is $6.50, then the cost for R of them is:

R*$6.50

We know that he wants to spend less than $39, then we have the inequality:

D*$4.25 + R*$6.50 < $39

And we also know that he wants to buy at least, 4 arrangements, then:

D + R ≥ 4

Now we have a system of inequalities:

D + R ≥ 4

D*$4.25 + R*$6.50 < $39

This has quite a few solutions, for example, he could buy 3 arrangements of daisies and 2 of roses, the total cost would be:

3*$4.25 + 2*$6.50 = $25.75, which is less than $39, and he is buying 5 arrangements, more than 4 as he wanted.

And there are a lot of other possible options.

Answer:

∠ EBF = 40°

Step-by-step explanation:

Given BF bisects ∠ CBE , then

∠ CBF = ∠EBF , substitute values

7x - 2 = 6x + 4 ( subtract 6x from both sides )

x - 2 = 4 ( add 2 to both sides )

x = 6

Thus

∠ EBF = 6x + 4 = 6(6) + 4 = 36 + 4 = 40°

Answer:

-4e-9

Step-by-step explanation:

3e-19-7e+10

3e-7e-19+10

-4e-9

The simplified expression is -4e - 9.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

3e - 19 - 7e + 10

Combine like terms.

(3e - 7e) - 19 + 10

-4e - 9

Thus,

The final expression is -4e - 9.

Answer:

78.5in

Step-by-step explanation:

C= 2(pi)r

C= 2 x 3.14 x 12.5

C= 78.5in

Answer:

78.5

Step-by-step explanation:

To find circumference, you need to multiply radius (r) times pi (3.14 or 22/7) times 2. So, you would do 12.5 times 2 times 3.14. You would get 78.5.

Answer:

I can't see the pictures clearly but its between Option A and Option C

Step-by-step explanation:

[tex]\frac{y^{2}-y^{1} }{x^{2}-x^{1} }=\frac{60-20}{42-14}=\frac{40}{28}=\frac{20}{14}=\frac{10}{7}[/tex]

14 + x + 5 = 2x

19 = x

Answer:

Step-by-step explanation:

You first have to find 6% of 35. Which is 2.1 and so you then multiply 2.1×3 which is 6.3 and then subtract 6.3 from 35. 35-6.3 which is 28.7 and then divide that by 3. Which is essentially 9.6 if you round up the decimal. Otherwise it'd just be 9.566667. So, I'd say each is 9.6 or 10 if you're rounding for the nearest whole number.

Answer:

Pretty sure 25%.

Step-by-step explanation:

First, you would need to see how many times 60 goes into 100, because a percent is ALWAYS over 100. You should get an answer of 1.66666667. Then you if you multiply it to one of the numbers then you have to do it to the other number. So, you would do 15 times 1.66666667. You would get 25. So, that would be 25 over 100 or 25/100. And 25 over 100 is 25%.
