Answer:
Step-by-step explanation:
50 elevens-1 elevens = ( 50 -1 ) elevens = 49 elevens
or 49 x eleven = 49 x 11 = _______ (use your calculator here)
V=1/3*S*h, S stands for area of the base and h is a height
The base of our pyramid is a rectangle, so the area is:
S=a*b=3*5=15m²
Hence, the volume is:
V=1/3*15*1=15/3=5m³
Answer: 5 m³
Answer:
the like terms are 2xy, -xy, and xy. In other words: 2, 4, & 6
solve for y in equation 1
x+y=7
y= 7-x
Then plug in y = 7x into second equation
7x+2x=6
9x=6
x=6/9
x=2/3
Now you know x. To find y, plug x into first equation
2/3 + y = 7
y = 7- 2/3
y = 19/3
Answer:
angle 2 = 122
Step-by-step explanation:
we can substitute the angles for x and x+64
since they are supplementary, we know the some is 180
so we can form the equation x + x + 64 = 180
solve for x and we get 58
so angle 2 is 122
