We can simplify this problem by pairing like terms together.
9x + 15x - 2x + 2
22x + 2
This expression can be simplified down to
22x + 2
<span>6(−3−x)−2x=14
x= -4
14=2c-6+3c
c= 4
</span><span>−7.5(x−3)=3.75
</span><span>x= 2.5
</span><span>3/5(r−7)=1
</span>r= 26/3
3.5 (t+6)=7
D) -4
Hope this helps ^.^

Answer: I think 28 miles
Step-by-step explanation:
you add 8 miles every 2 hours until you reach 9 hours and since 9 is an old number you add 4 instead.
Let x be the score Amaya gets on the final test. She wants her average of all 3 tests to be between 80 and 89:
<span>80 ≤ (78 + 91 + x) / 3 ≤ 89 </span>
<span>Multiply everything by 3: </span>
<span>240 ≤ 78 + 91 + x ≤ 267 </span>
<span>240 ≤ 169 + x ≤ 267 </span>
<span>Subtract 169 from everything: </span>
<span>240 - 169 ≤ x ≤ 267 - 169 </span>
<span>71 ≤ x ≤ 98 </span>
<span>Answer: </span>
<span>She needs to score between 71 and 98 to get a B for the course.</span>
