-2,-7 because you go the same ammount in the opposite direction
Place value of 4 is 4/100
The answer would be D because you are subtracting a positive 17 from a positive 88
Given:
m∠1= x° and m∠2 = (x +50)°.
To find:
The value of x, m∠1 and m∠2.
Solution:
From the figure it is clear that, transversal side intersect the opposite sides which are parallel and form ∠1 and ∠2.
Sum of same sided interior angles is 180 degrees. So,
Divide both sides by 2.
Now,
Therefore, the correct option is C.
1)First, understand that whatever your equation is it’s always gonna be less than 100, because she doesn’t wanna get more than 100 ft.
*>100
2) remember that Lainey already dropped 20 feet. The amount of minutes is your unknown variable (x)
3) so, note that the rate is 20 ft/minute. If you multiply 20 by the amount of minutes she has to descend (your unknown variable: x) you cancel out the “minutes” in the 20 ft/minute fraction.
(Ex. 20ft/min *multiply* x [unknown]minutes= 20ftx)
This is what you want since you need all of the terms to be the same unit to solve with algebra.
4) so, to put it all together you have, 20 times x (representing the unknown amount of minutes) plus 20 (representing the amount she has already fallen) is greater than 100
* 20x+20>100
