6a+b = 4

5a + 2b = 1

The value of the unknown **variables **a and b in given **equations **are 1 and -2 respectively.

An **equation **is a formula that expresses the equality of two **expressions**, by connecting them with the equals sign =.

Given are two **equations**,

6a+b = 4......(i)

5a + 2b = 1.......(ii)

Solving them by using **substitution** method,

6a+b = 4

b = 4-6a......(iii)

Using equation (iii) in equation (ii)

5a + 2(4-6a) = 1

5a+8-12a = 1

-7a = -7

a = 1

Put a = 1 n eq(iii)

b = 4-6·1

b = 4-6

b = -2

Hence, The value of the unknown **variables **a and b in given **equations **are 1 and -2 respectively.

2 inches / 25 miles = 31 inches / x

Cross-multiply the proportion:

2x inch-miles = 775 inch-miles

Divide each side by 2 inches:

x miles = 775/2 = 387.5 miles

Cross-multiply the proportion:

2x inch-miles = 775 inch-miles

Divide each side by 2 inches:

x miles = 775/2 = 387.5 miles

Answer: 1st graph is the answer, empty boxes for number of friends are 5 and 15 and empty boxes for cost of party are 200 and 400

Step-by-step explanation: when you multiply 20 by the amount of people you get the cost of the party (proportional relationships)

__X__|__Y___

1 | 20

2 | 40

2 | 60

4 | 80

5 | 100

6 | 120

7 | 140

C is the answer

Step by step explanation:

To get the answer you must expand the brackets (multiply the number or numbers outside the brackets with the ones within to remove them)

To do this you must first in 2(8+6) multiply 2 times 8 which is 16

Then you would multiply 2 times 6 which is 12

As the operation is a + that would mean the answer is 16+12

Hope this helps!
