[tex]\\ \rm\Rrightarrow 5-6a-3=6[/tex]

[tex]\\ \rm\Rrightarrow -6a+2=6[/tex]

[tex]\\ \rm\Rrightarrow -6a=6-2[/tex]

[tex]\\ \rm\Rrightarrow -6a=4[/tex]

[tex]\\ \rm\Rrightarrow a=\dfrac{4}{-6}[/tex]

[tex]\\ \rm\Rrightarrow a=\dfrac{2}{-3}[/tex]

Now

[tex]\\ \rm\Rrightarrow a+2[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{2}{-3}+2[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{2-6}{-3}[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{-4}{-3}[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{4}{3}[/tex]

Answer:

7/3

Step-by-step explanation:

5 - 3(2a+1) = -4 + 10

=> 5 - 6a + 3 = 6

=> 5 - 6 + 3 = 6a

=> 2 = 6a

=> 6a = 2

=> a = 2/6

=> a = 1/3

a + 2

1/3 + 2

=> 1/3 + 6/3

=> 7/3

The trick is to let the letters =  points of a clock that keeps time this way.

l = 9 oclock

C = 3 oclock

-H= -8

Formula

(x - l) / C = -H

Solution

Substitute the givens into the equation

(x - 9) / 3 = -8                 Multiply both sides of the equation by 3

3*(x - 9)/3 = -8*3            Simplify

(x - 9) = - 24                   Remove  the brackets

x - 9 = - 24                     Add 9 to both sides.

x-9+9 = -24+9               Combine

x =  - 15

Answer:

x=12

Step-by-step explanation:

2x-15 + 2x-6 = 15

4x = 36

x = 9

2 x 9 - 6 = 12

Yes, he earns the same amount per hour for the fence because in two hours he earned 15. The pressure washing and deck was 4 hours and every 2 hours he got 15.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

It is given that, Bradley $15 for painting a fence for two hours and 30 dollars for pressure washing the patio and deck for 4 hours.

Bradley $15 painting a fence for two hours, its unit rate is

=$15 / 2 hours

=$ 7.5 per hour

If 30 dollars for pressure washing the patio and deck for 4 hours, the unit rate is

=$ 30 /4 hours

=$ 7.5 / hour

Thus, he earns the same amount per hour for the fence because in two hours he earned 15. The pressure washing and deck was 4 hours and every 2 hours he got 15.

Answer:

  3 48-cent stamps

  9 7-cent stamps

Step-by-step explanation:

The number of 48-cent stamps Amy can use is less than 207/48 ≈ 4.3, so we can find the numbers by trial and error. We want ...

  48a +7b = 207 . . . . . . postage in cents, where a, b are the numbers of stamps

  b = (207 -48a)/7 = 29 4/7 -a(7 -1/7) = (29 -7a) +(a+4)/7

In order for b to be an integer, we must have (a+4) a multiple of 7. The least value of 'a' that will make this true is a=3. That value gives ...

  b = (29 -7·3) +(3+4)/7 = 8 +1 = 9

Amy used 3 48-cent stamps and 9 7-cent stamps.

Answer:

A=1633

B=1617

C=1610

D=1626

Step-by-step explanation:

I am not totally sure about 3409 ?

None of the following option sum up to 3400 or close.

Sum is addition

According to the question given we have to determine which of the following is 3409.

A. ( 3 × 104 ) + ( 4 × 103 ) + ( 9 × 101 )

= 312 + 412 + 909.

= 724 + 909

= 1633.

B.  ( 3 × 103 ) + ( 4 × 102 ) + ( 9 × 100 )

= 309 + ......

C. 300 + 400 + 900 not sum up to 3400.

D. 300 + 400 + 900 again not sum up to 3400

So, none of the following options sum up to or sum up close to 3400.

Answer: a= [tex]g+2 / 2[/tex]

Step-by-step explanation:

g= -2 + 2a

>> -2+2a=g ( side change )

>> -2+2a +2 = g+2 ( adding 2 both side)

>> 2a = g+2

>> 2a /2 = g+2 /2 ( divide by 2 both side)

>> a= g+2 /2

Answer:

A. An Algebraic Expression

Step-by-step explanation:

Since we have no equal sign in the problem, we know that it is an expression. An equation has an equal sign and another value so we can simplify to find the value of whatever variable we are working with. We also know that it is not anything numerical because we are working with variables. With this information we will see that the correct answer is A.

Answer:

3/5 of 30 = (3/5)*30

3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/5

3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/5

3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/53/5 of 30 = 18
