Answer:
140
Step-by-step explanation:
1 and 3 are vertical angles meaning they are equal. 4 and 3 make a straight angle. A straight angle is 180.
180-140=40
2 and 4 are straight angles so should be equal.
1=140
2=40
3=140
4=40
210 ÷ 6 = 35 miles to the gallon
280 ÷ 35 = 8 gallons for 280 miles
Answer:
x < - 4
Step-by-step explanation:
- 5 - 3x > 2(10 + 2x) + 3 ← distribute parenthesis and simplify right side
- 5 - 3x > 20 + 4x + 3
- 5 - 3x > 4x + 23 ( add 3x to both sides )
- 5 > 7x + 23 ( subtract 23 from both sides )
- 28 > 7x ( divide both sides by 7 )
- 4 > x , that is
x < - 4
So use pemdas to figure out x, you can use that to figure out the fractions and stuff
I don't know but good luck
