1. False, if x is equivalent to 2 then it would be x+2=2x
2. True, if x equals 3 then its 3+6=3x=9 so 9/3=3 therefore x=3
3. False, if x is equivalent to 1 then it’d be 1+4=5x
4. True, if 5+5=2x then 2x=10 which is correct
5. False, if x is 4 then 4 multiplied by 4 =16
Answer:
13.76
Step-by-step explanation:
We want year 10; this means we substitute 10 in place of x:
y=-0.34(10²)+4.43(10)+3.46
y = -0.34(100)+4.43(10)+3.46
y = -34+44.3+3.46 = 13.76
3s+28=85, take away 28 from both sides of the equals to give you 3s=57, divide by 3 on both side to give you s=19.
