Answer:
6.7
Step-by-step explanation:
There would be an open circle on positive 12 with the arrow moving to the right.
PEMDAS order refers to parentheses, exponents, multiplication, division, addition, and subtraction. So, 2*5=10 and 34+10=44.
The answer is 12cm because area (420) divided bye height (35) gives you the corresponding side 12cm.
79-y=2y+22
Add y on both sides
79=3y+22
Subtract 22 from both sides
57=3y
Divide by 3 on both sides
19=y
