Answer:
17
Step-by-step explanation:
3 + 7 * 6 / 3
PEMDAS says we multiply and add before adding and subtracting so we multiply first (going from left to right)
3 + 42 / 3
Then we divide
3 + 14 = 17
the answer is 2.5
explanation: area= base x height
area=2.5 x 1 which is 2.5
Answer:
9
Step-by-step explanation:
-15 - -14y = -9
two negatives (close together) makes a positive
-15y + 14y = -9
add like terms
-1y = -9
get y alone (divide whats in front of it) and do the same on the other side
-1y/-1 = -9/-1
if you divide two negatives it makes it positive so youll get 9
1. simplify 11/5
- 58/10 - 11/5 =0
2. Divide z by 11/5
- 58/10 - 5z/11 =0
3. simplify 29/5
29/5 - 5z/11 =0
4. calculating the least common multiple
4.1 find the least common multiple
the left denominator is: 5
the right deniminator is: 11
least common multiple:55
....
solution z=319/25 = 12.760
