8x( 47 ) = 8x + 7x
8x( 47 ) = 8x( 2 ) - x
8x( 47 - 2 ) = - x
8x( 45 ) = - x
360x = - x
x = -360x
I don't think the question can be done
Is the question wrong?
because there's no answer other than 0.
h=h+vi t-4.9t^2
h=h=0
0=vi t-4.9t^2= t(vi-4.9t)
t= 30/4.9 m/s
D/20=20/15
d=400/15
d=80/3
d=26 2/3 miles
1/2 is bigger because 1/4 is half of half.
Answer: x = 780
Step-by-step explanation: Well <u><em>percent</em></u> means <em>over 100</em> so we can set up an equation for this problem by reading it from left to right.
So we know that <u><em>10%</em></u> means <em>10/100</em>, <u><em>of</em></u> means times, <em><u>what</u></em> <em><u>number</u></em> means <em>x</em>, <u><em>is</em></u> means <em>equals</em>, and <em><u>12</u></em> means 12.
Notice that <em>10/100</em> can be reduced to 1/10.
So rewriting our problem we have <em>X/10 = 78</em>.
To get rid of the fraction, we multiply both sides of the equation by 10 and we have <em>x = 780</em>. So, 10% of 780 is 78.
Now let's check our answer back in the original problem to see if it makes sense.
We have <em>10% of 780 is 78</em>. Well we know that 100% of of 780 would be 780 so 10% of 780 should be alot less than 780 so 78 seems to make sense.
