There are 9.14 servings because 64 divided by 7 eill give you 9.14 when rounded
35 in. because a pentagon has 5 sides and have to divide the total amount of yarn to the sides.
Answer:
Step-by-step explanation:
→ Expand brackets
→ Add 8 to both sides to collect the whole numbers
→ Add -4m to both sides to collect the m terms
→ Divide both sides by -10 to isolate m
Answer: x = 150°
Step-by-step explanation:
The tangent intersects the circle's radius at a 90° angle, so ∠OAC = ∠OBC = 90°.
AOBC is a quadrilateral and we know that sum of interior angles of quadrilateral equals to 360°.
Now,
∠OAC + ∠OBC + ∠AOB + ∠ACB = 360°
90° + 90° + x + 30° = 360°
210° + x = 360°
x = 360° - 210°
x = 150°
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.
