Answer:
12
Step-by-step explanation:
21x + 4x = 300 Put brackets around the first two terms.
(21x + 4x) = 300 Pull the x outside the brackets. Use the distributive property. Combine the left
25x = 300 Divide by 25
25x/25=300/25 Do the division
x = 12

Step-by-step explanation:
dude trust me
With questions like this (to see if theyre parallel), all you have to do is see if lines have a congruent slope. if yes (ex: 2 and 2), then they are parallel. if the slopes are opposites (ex: 4 and -1/4), then they are perpendicular. If they have no such relation (ex: -3 and 1/7), then they are neither.
with this problem, find the slope by separating the same variable in each equations, like this:
2x + 7y = 6
-2x -2x
7y = -2x + 6
(the second equation is already separated) so now we have
7y = -2x + 6 and 7y = 2x + 6
since -2 does NOT equal 2, these two graphs/lines are NOT parallel.
Hope this helped!
Answer:
27
Step-by-step explanation:
19√2 = 26.8701
2 sig figs is the ones place and one decimal place after (tenths place) in this problem.
Only way to find your answer is to plug 19√2 into your calc.
