2a + b = 15.7
length a is longer than b.
a = 6.3
2a + b = 15.7
(2*6.3) + b = 15.7
12.6 + b = 15.7
b = 15.7 - 12.6
b = 3.1
therefore the base length is 3.1 cm
answer:
6 more hundreds
step-by-step explanation:
- six hundreds mean 600
- 600 + 400 would be 1000
- therefore, we would need 6 more hundreds
You first have to distribute the negative to the second pair of parenthesis. So the new equation would be 2n-4-4n+3. Next you combine like terms. So your final answer is -2n-1.
Step-by-step explanation:
The perpendicular line has a slope that is the negative reciprocal of the other line's slope. So, in this case, the slope should be 1/3 (it's positive because a negative times a negative is a positive). This gets rid of all of the answers except for the last, I suppose.
