Answer:
0
Step-by-step explanation:
Each expression is a way to write the sum ...
3 + 5 + 7 + 9
That sum in each case is 24, so the difference is 24-24 = 0.
Answer:
One piece of pizza = $2.5
One candy bar = $1
Step-by-step explanation:
Call 1 pizza a, 1 candy bar b. We have:
2a + 3b = $8
=> 3(2a+3b) = 3. $8
= 6a + 9b = $24
and
6a + 5b = $20
=> (6a + 9b) - (6a + 5b) = 9b - 5b = 4b = $24 - $20 = $4
=> b = $1
=> 2a + $3 = $8
=> 2a = $5
=> a = $2.5
So one piece of pizza = $2.5, one candy bar = $1
Answer/Step-by-step explanation:
✅m<1 = 180 - 52° = 128° (consecutive interior angles)
✅m<2 and 52° are alternate interior angles. Alternate interior angles are congruent.
Therefore:
m<2 = 52°
✅m<3 and 47° are alternate interior angles. Alternate interior angles are congruent.
Therefore:
m<3 = 47°
✅m<4 = 180 - m<3 (linear pair)
m<4 = 180 - 47 (substitution)
m<4 = 133°
✅m<5 = 180 - (52 + 47) (angles on a straight line)
m<5 = 81°
