Since there are three kids, 3x3=9. 80-9=71. Danny and Mark and Evans ages combined is 71 years
Answer:
187 cm²
Step-by-step explanation:
The bottom rectangle area is easy, it is 15*9 = 135 cm².
To find the area of the triangle, you only need the base width and its height (you don't need the hypotenuse). You can then use the formula: area triangle is base times half height.
The base width is 15-7 = 8 cm
The height is 22-9 = 13 cm
So the area of the triangle is 13*8/2 = 52 cm²
Together with the 135 of the rectangle that sums to 52+135 = 187 cm².
Answer:
Step-by-step explanation:
-(-)=+
so -8-(-3)=-8+3
=-5
0.8888888 = 8/9
2.8888888 = 26/9
-2.888888 = -26/9
Answer:
X
Step-by-step explanation:

X
As we know that, he has 6 students, so the fraction of his workday is spent with each student is:
X : 6
= X
Hope it will find you well during the time of isolation.
