Answer:
152
Step-by-step explanation:
6840 divided by 45 is 152
It depends on how deep the submarine is... do you happen to know that?
Point slope form is y - y1 = m (x - x1), so the point on the line is (-7, 3).
You can plug the point back in the check. Slope is given.
y - 3 = 4 (x- (-7))
y - 3 = 4 (x + 7)
It's correct, so you know that B (-7, 3) is the answer.
Answer:
Each pair of shoes cost 26$
Step-by-step explanation:
<em>find the total cost for shirts</em>
2 shirts * 12$ each
2 * 12 = 24
they spent 24$ on shirts
<em>create an equation</em>
24$ shirts + x$ shoes = 76$
24 + x = 76
<em>subtract 24 from both sides of the equation</em>
24 + x - 24 = 76 - 24
x = 76 - 24
x = 52
they bought 2 pairs of shoes that cost the same amount
52 = x + x
52 = 2x
<em>divide both sides of the equation</em>
52/2 = 2x/2
52/2 = x
26 = x
each pair of shoes cost 26$
It is also the same as 8 to the power of 7
which looks something like this 8^7
you can also do it by doing 64×64×64×8
then do 64×64
multiply that answer by 64
multiply that answer by 8
this will work with any question and you can do it without a calculator and on paper.
