5 is you median
4 is your mean
64:4 = x:30
30/4 = 7.5
64 x 7.5 = 480 letters in 30 seconds
Answer:
14
Step-by-step explanation:
The perimeter is the sum of the sides, so we have
2x+x+15+4x-7=57
= 7x+8
Subtracting 8 from both sides, we get
7x= 49
Dividing 7 from both sides, we get
x=7
Our sides are then 2x=14, x+15=22, and 4x-7=21. 14 is our answer
Answer:
Reduction
Step-by-step explanation:
The resulting shape M'S'V' is smaller than the original shape MSV, so it is therefore classified as a reduction.
Answer:
56=78b
Step-by-step explanation:
The vertices of quadrilateral MNPQ are M(28, 1), N(3, 4), P(7, 21), and Q(24, 24).
a. The coordinates of M' are (16,4) after a translation. State the translation rule.
b. Use GeoGebra to complete a 90° rotation around the origin
