Evelyn has initially $524.96, then she paid $32.50, so she will have less than $500. In order to have at least $500, she needs to deposit the value x.
So the initial value, minus the value paid, plus the deposit needs to be greater than or equal 500, so we have the inequality:
Solving this inequality for x, we have:
Therefore the correct option is the first one (a).
The algebraic rule describes the 180° counter-clockwise rotation about the origin =======> Answer: Rule for 180 degrees Counter-Clockwise Rotation =======> ( X , Y ) =========> ( - X, - Y ) ====> Make X + Y Signs Opposite.
Rotations Counter-Clockwise:
Rotation of 90 degrees ========> Switch X + Y, Make Y Opposite.
Rotation of 270 degrees ======> ( X, Y ) ===> ( Y, - X ) ==> Switch X + Y, Make X Opposite.
Hope that helps!!!! : )
(0.99x) + 18 = 1.19x
18 = 1.19x
- 0.99x
18 = 0.2x
18/0.2 = x
90 = x
(She must by 90 tiles for the cost at both stores to be the same, Cheers!)
Answer:
count that many 9s by the number your multiplying by.
Step-by-step explanation:
so example think of it like this =
9 x 9
9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 = 81
9 x 9 = 81
that easy ! just add the amount of 9s to the number your multiplying by . if u still need help, go on You Tube and search MathAntics .. he explains every different types of math amazing !
