What is the value of x in the equation 7x 2y = 48 , when y = 3?

What is the value of x in the equation 7x + 2y = 48

Given y=3

We plug in 3 for y and solve for x

7x + 2y = 48

7x + 2(3) = 48

7x + 6 = 48 ( subtract 6 on both sides)

7x + 6 - 6 = 48 -6

7x = 42

Divide by 7 on both sides

x = 6

the value of x = 6

We can say the value of x=6 when the value of y = 3

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
