Answer:
$25.96
Step-by-step explanation:
First, you turn the percent into a decimal, which gives you .18. Then, you multiply $22 by .18. Finally, you add the $3.96 that you get by multiplying $22 by .18, and you get the answer that is above. Plz mark brainliest if correct.
7/8 is the answer hope this helps
Answer:
4 hours
Step-by-step explanation:
The general formula for distance, rate and time is:
d = rt, where distance is the product of rate multiplied by time
Given that one train is moving at a rate of 70 mph and one is moving at a rate of 62 mph in the opposite direction, the combined distance over time is equal to 528 miles. Using the variable 't' for time:
70t + 62t = 528
Combine like terms: 132t = 528
Divide both sides by 132: 132t/132 = 528/132 or t = 4 hours
1). Enrico Fermi directed construction of the the thing
that achieved the first sustained nuclear chain reaction,
under the stadium at the University of Chicago.
3). 'Fission' means splitting one big thing up into several
smaller things.
4). The atomic mass of an atom is close to the sum of all
the neutrons and protons in its nucleus.
5). 'Fusion' means several small things joining to form a
bigger thing.
6). Henri Becquerel is credited with discovering radioactivity.
7). The names of Madame Marie and Mssr. Pierre Curie were
appropriated after their deaths and used as the unit of radiation.
2). I have no idea what that symbol means, but 'neutron' is
the only choice left.
Step-by-step explanation:
You're asking why

let's transpose the first equation for y
-2x-6y=18
-6y=18+2x
6y=-18-2x
y=-18/6-2x/6
y=-3-⅓x as required
