7P3= 7!/(7-3)!
= 7!/4!
= 7*6*5
= 210
C.210
Answer:
w = 18
Step-by-step explanation:
6(33 - w) = 90 ( divide both sides by 6 )
33 - w = 15 ( subtract 33 from both sides )
- w = - 18 ( multiply both sides by - 1 )
w = 18
Answer:
C. 116º
Step-by-step explanation:
Both sides are congruent, so the triangle is an isosceles triangle. So angle Z will have to be congruent to angle X. Add together the two angles, (32 + 32) and subtract the sum from 180º since all triangles add up to 180º.
32 + 32 = 64
180 - 64 = 116
Answer: p = 6
Step-by-step explanation:
HI !
px + 3y - ( p-3)=0
a₁ = p , b₁ = 3 , c₁ = - (p-3)
=====================
12x + py - p=0
a₂ = 12 , b₂ = p , c₂ = -p
since , the equations have infinite solutions ,
a₁/a₂ = b₁/b₂ = c₁/c₂
p/12 = 3/p = p-3/p
--------------------------------------
p/12 = 3/p
cross multiply ,
p² = 36
p = √36
p = 6
for the value of p = 6 , the equations will have infinitely many solutions
