x = - 3

Step-by-step explanation:

Given the 2 equations

y = x + 7 → (1)

y = 3x + 15 → (2)

Since both equations express y in terms of x, equate the right sides

3x + 15 = x + 7

Subtract x from both sides

x + 15 = 7 ( subtract 15 from both sides )

x = - 8 ( multiply both sides by 3 )

8x = - 24 ( divide both sides by 8 )

x = - 3

step-by-step explanation:

this woman was an important writer and propagandist during the american revolution. she was a member of the committee of correspondence (in fact the committee was formed in her home) and was an advisor to many of the revolutionary leaders, including george washington and john adams. who was this revolutionary woman?

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.
