PRM +MPR+PMR=180。(angle sum of triangle)
70。+35。+PMR=180。
PMR=75。
x+PQR=180。(angle on straight line)
x=105。
MQO=QOM
QMO+2MQO=180。(angle sum of triangle)
105+2MQO=180。
MQO=37.5。
MQO+y+MPN=180。（angle sum of triangle)
37.5+70+y=180。
y=72.5
Answer:
C
Step-by-step explanation:
To find the volume of a rectangular prism, you need to multiply the width by the length by the height (the three given side lengths).
Only C and D do that. Meanwhile A and B just add them, which is not what you're supposed to do.
So, we know it's not A or B.
After finding the volume of each of the prisms, you need to add them to find the combined volume.
D multiplies them, so it's not D.
Therefore it must be C, which correctly multiplies the side lengths and then adds the volumes together at the end.
Answer:
55 chairs
Step-by-step explanation:
825/15=55
You can use the substitution method for this problem
Since -3y+8=x you can
Use the equation -7(-3y+8) -6y=4
You then distribute and solve
21y-56-6y=4
15y=60
Y=4
You then plug y into one of the original equations
X=-12+8
X=-4
(-4,4)
Answer:
39.66
Step-by-step explanation:
If the divisor is not a whole number, move decimal point to right to make it a whole number and move decimal point in dividend the same number of places.
Divide like you usually do
Put decimal point directly above decimal point in the dividend.
