Answer:
36
Step-by-step explanation:
Create an equation : 12 for how many pieces Stephanie took, 4 for how many children she has and 6 for how many pieces each child got:
12+ (6*4) = x
Solve:
12+24 = 36

p < 14/3
Step-by-step explanation:
Answer:
∠ 5 = 133°
Step-by-step explanation:
∠ 1 and ∠ 2 are adjacent and supplementary, thus
∠ 1 = 180° - 47° = 133°
∠ 1 and ∠ 5 are corresponding and congruent, thus
∠ 5 = ∠ 1 = 133°
Answer:
7
Step-by-step explanation:
Those are alternate interior angles. Alternate interior angles are the ones that happen at different intersections along the transversal but on opposite sides while inside the lines the transversal goes through. If these lines are parallel, then the alternate interior angles are congruent. Same thing the other way around. Alternate interior angles being congruent implies those lines are parallel.
So we are looking to solve:
3x-2=2x+5
Subtract 2d on both sides:
x-2=5
Add 2 on both sides:
x=7
