Answer:
Not true
Step-by-step explanation:
x + (2x + 5) = 3(x – 4)+7
Opening bracket on left and side and distributing 3 over (x-4) on right hand side
x+2x+5=3x-3 x 4 + 7
adding like terms
3x+5=3x-12+7
3x+5=3x-5
Hence
5 = -5
Which is not possible , Hence the equation given to us is false.
Answer:
60m/s
Step-by-step explanation:
velocity of the while moving is 30 m/s and it becomes 90 m/s after speeding up at constant rate. so the average velocity of the journey is
[90+30] /2
=60 m/s
multiply the number three times by the other number.
Answer: 2x = 18
Step-by-step explanation:
x = 9
2x = 2(9) = 18
(a) There are 1/4 cups of flour per serving
<u>WORK:</u> 1.5/6=1/4 (change 1 1/2 into decimal)
(b) <u>**not sure**</u> There are approximately .18 cups of sugar per serving.
<u>WORK:</u> 9/2+4/12=13/12 and then divide 13/12 by 6.
(c) You need 2 1/4 cups of flour to make 9 servings.
<u>WORK:</u> 1.5/2=.75
1.5+.75=2.25=2 1/4
(d) Someone would need to know the amount of sugar to properly make the recipe and if needed know how much to put if you wanted to split the recipe.
