I walked past the crab, which was right BY the ocean
Answer:
I believe the answer would be step 1: 12x + 15 = 12, and step 2: 12x = -3.
Step-by-step explanation:
3(4x + 5) = 12, you would foil and do 3 times 4x which is 12x, then do 3 times 5 which is 15. So the result would be 12x + 15 = 12. And the step 2 that goes along with this answer. you would do -15 on both sides of the equal sign, so now you have 12x = 12 - 15 which is -3, so it would be 12x = -3
Step-by-step explanation:
9.94 => 10 (1s.f.)
29.7 => 30 (1s.f.)
Hence we estimate the value of 9.94² * 29.7
as 10² * 30 = 3,000.
1 box =1 foot so you would have to count the boxes away from her
Answer:
126 degrees
Step-by-step explanation:
We are given BC is congruent to BE therefore BDE is congruent to BDC. We can use this to solve for p:
9p-81=5p-17
Move like terms to one side
4p=64
Divide 4 from both sides
p=16
Therefore:
BDC=9(16)-81
BDC=144-81
BDC=63
CDE=BDC+BDE
CDE=2(63)
CDE=126 degrees
