Answer:
expanded form: x= (159)/(10) decimal form: 15.9 mixed number form: x= 15(9)/(10) hope im right
Remove all the brackets
3(7 + 2x) + 3 = 3(5 + x) − 9(x + 1)
21 + 6x + 3 = 15 + 3x - 9x - 9 Collect like terms.
24 + 6x = 6 - 6x Add 6x to both sides.
24 + 6x + 6x = 6 Subtract 24 from both sides
12x = 6 - 24
12x = - 18 Divide by 12
x = - 18 /12
x = - 1.5
Check
3(7 + 2*(-1.5)) + 3 = ? 3(5 + -(1.5) - 9(-1.5 + 1)
3(7 - 3) + 3 =? 3(3.5) - 9*(-1/2)
3*4 + 3 =? 10.5 + 4.5
12 + 3 =? 15 And it checks.
So do
25x16=400
this shows how many raffle tickets were sold all together
Then do 400x$15 =$6000
So all together they raised $6000
Jeff put 1/6 into his bank. You first make the fractions into common denominators. The nearest number that works would be 15. 1/3 changes into 5/15, 1/2 becomes 7.5/15.
7.5/15 + 5/15 is 12.5/15. Simplified is 5/6.
6/6 minus 5/6 gives you 1/6, therefore the answer is 1/6. Hope this helps!
