<span>one way to solve this kind of problems is by doing a little bit of reversal
75 % * X = 54
75/100 * X = 54
(we move 75/100 to the right, since it's a fraction the top and bottom number will be reversed)
X = 54 * 100/75
X = 5400 / 75
X = 72 Hope I helped! :) Cheers!</span>
X + 3 equals up to undefined
Answer:
(3y+2)(y+7)
Step-by-step explanation:
I think you meant (y+7)+3y(y+7)+(y+7). Anyways, we have to count the number of (y+7) there are. The first term tells us we have 1 group. The second term tell us we have 3y groups. The last term tells us we have 1 group. Therefore we have 1+3y+1 groups of y+7 which gives us (3y+2)(y+7)
1.) Is -4
2.) Is -1
I just took the test, So I know that's the right answer! :)
Hope this helps. :)
Answer:
<em>The Sahara Desert is 258 °F warmer that Antarctica.</em>
<em></em>
Step-by-step explanation:
Temperature at Antarctica = -123 °F
Temperature at the Sahara desert = 135 °F
The difference in temperature = 135 - (-123) = 135 + 123 = 258 °F
This means that the Sahara Desert is 258 °F warmer that Antarctica.
