Maria started with 37 boxes.
Given:
7 boxes bought
half of the boxes were destroyed in the fire.
22 boxes left
Find the beginning number of boxes.
Let x be the beginning number of boxes.
(x + 7)/2 = 22
2((x+7)/2) = 2(22)
x + 7 = 44
x = 44 - 7
x = 37
To check:
x + 7 = 37 + 7 = 44
44 * 1/2 = 22
22 = 22
Answer:
1 = 52°
2=79°
3= 38°
Step-by-step explanation:
each triangle equals 180°
and 1 and 3 also make a right angle which should always be 90°
Answer:
615.8
Step-by-step explanation:
Answer:
(x - 5)(x + 3)
Step-by-step explanation:
Given
x² - 2x - 15
Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (- 2)
The factors are - 5 and + 3, since
- 5 × 3 = - 15 and - 5 + 3 = - 2, thus
(x - 5)(x + 3) ← in factored form
