Answer:
Michael is 21 years old while Jean is 7 years old.
Step-by-step explanation:
Given that Micheal is three times as old as Jean, but in seven years he will be twice old as she will be, to determine how old are they both at this time, the following calculation must be performed:
M = 3J
M + 7 = 2J + 7
7 = 1/3
7 x 3 = 21
21 + 7 = 28
7 + 7 = 14
21 / 7 = 3
28 / 14 = 2
Therefore, Michael is 21 years old while Jean is 7 years old.
Multiply length times width to find the area. 6.5x11= 71.5
Answer:
x is 35 cm
Step-by-step explanation:
To find the value of x, we will divide the volume by the cross-section
Mathematically, that will be;
4375/125 = 35 cm
Answer:
1. (-2,-7)
2. (3,-9)
3. (7,-2)
4.(-3,9)
Step-by-step explanation:
Since the reflection is across the x-axis, the y-coordinate will be flipped.
Example: (-7,4) would become (-7,-4)
HOWEVER, if the reflection is across the y-axis, the x coordinate will be flipped.
Example: (-7,4) would become (7,4)
Answer:
X=10.2
