Answer:
12.)-5
13.)-16
14)-20
15)6
16)-13
17)1
18)-13
19)15
20)-10
Step-by-step explanation:
12.)-x=2+3
x=5/-1
so,x=-5
13.)-4=(-2×8+x)/8
-4×8=-16+x
-32+16=x
so,x=-16
14)(7×4+m)/4=2
28+m=8
so,m=-20
15)4n=34-10
n=24/4
so,n=6
16)-2a=22+4
a=26/-2
so,a=-13
17)a+3=2×2
a=4-3
so,a=1
18)-133+3=10x
-130=10x
so,x=-13
19)4+1=v/3
5*3=v
so,v=15
20)1=3+r/5
now,
Take LCM,
We get,
1=(3*5+r*1)/5
now,
by moving 5 into LHS
We get,
1*5=15+r
5=15+r
by moving 15 into left hand side,
We get ,
5-15=r
so,r=-10 because when we subtract smaller from bigger we have to take the sign of bigger.
Answer:
16
Step-by-step explanation:
Simplify the following:
4 + 3×2^3/2
3×2^3/2 = (3×2^3)/2:
4 + (3×2^3)/2
Combine powers. (3×2^3)/2 = 3×2^(3 - 1):
4 + 3×2^(3 - 1)
3 - 1 = 2:
4 + 3×2^2
2^2 = 4:
4 + 3×4
3×4 = 12:
4 + 12
4 + 12 = 16:
