23/7+61/3 is done first due to PEMDAS
so the lcm of 7 and 3 is 21
So 23*3 + 61*7 divide the whole by 21 which is 7*3
The answer will come out to 496/21
Then outside the bracket the whole is times 34/3
So 34/3*496/21=
16864/64
We can’t simplify it more so that’s the answer
Answer:
20i+4i =16i-19
Step-by-step explanation:
The answer if 7 years, if you multiply 2,000 by .02 it equals 40. so you divide 280 by 40 and get 7
You can revise: the sum of the two adjacent angles is 180°
and the sum of the measurements of the three corners in a triangle is also 180°
<1= 180°-57°=123°
As <2=52°, so we have <3= 180°-(28°+71°+52°)= 180°-151°=29°
