Answer:
7m-3x-1
10x+26
7x-12
Step-by-step explanation:
3m - 1 + 4m -3x
sum terms by the same variable:
3m+4m=7m
we have:
7m-3x-1
7(3+2x)-4x+5
apply the distributive property:
7*3+7*2x-4x+5
we have:
10x+26
3x+4(x-3)
apply the distributive property:
3x+4*x-12
we have:
7x-12
X = 10
y = -2
x/y = 10/-2
x/y = -5
Hence, x/y = z
Answer:
π
Step-by-step explanation:
the formula is V = πr2h
pie times radius to the second power times hight
Answer
y= 4
Step-by-step explanation:
6x-7y=22
6x(-1)-7y=22
-6-7y=22
-7y=22+6
-7y=28
y=-4
If T and V are complementary angles, their sum is 90°.
V + T = 90°
48° + (2X+10)° = 90° . . . . . . . substitute given information
2X + 58 = 90 . . . . . . . . . . . . .. collect terms
2X = 32 . . . . . . . . . . . . . . . . .. subtract 58
X = 16 . . . . . . . . . . . . . . . . . .. divide by 2
The value of X is 16.
