Step-by-step explanation:
<u>Step 1: Set up Equation</u>
x + (x + 65) + 25 = 180
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 2x + 90 = 180
- Isolate <em>x</em> term: 2x = 90
- Isolate <em>x</em>: x = 45
67,436,828,104 rounded to the nearest million is 67,437,000,000. To round to the nearest million, you first check to see what is in the hundred-thousands place. If the number in the hundred-thousands place is a number between 0-4, the millions place stays the same. If the number in the hundred-thousands is 5-9, the millions place value goes up one.
Answer:
F=140°
Step-by-step explanation:
130+120+110=360
720-360=360
40+60+20=120 360+120=480
480÷3=160 x=160
160-20=140
f=140°
