One is c and 2 is c.
1. 82-180=98
2.2x+28=6x-4 ---> x=6 plug 6 in for x and the answer is 40
10 1/2 + 9 3/8 + 7 5/6 = 27 17/24 hot dogs
Answer is A
Answer:
x = 9
Step-by-step explanation:
2 sides are 4 less than x, that is x - 4
The perimeter is the sum of all 3 sides, thus
x + x - 4 + x - 4 = 19, that is
3x - 8 = 19 ( add 8 to both sides )
3x = 27 ( divide both sides by 3 )
x = 9
Answer:
2A/b = h
4 inches = h
Step-by-step explanation:
A = 1/2bh in terms of h
Multiply each side by 2
2A = bh
Divide by b
2A/b = h
Let A = 18 and b = 9
2*18/9 = h
4 = h
