What is x+4/5=2/3- x-3/6

Answers

Answer 1

Answer: $x+(4)/(5)=(2)/(3)-x-(\not3^1)/(\not6_2)\n\nx+(4)/(5)=(2)/(3)-x-(1)/(2)\n\nfind\ LCD((4)/(5);\ (2)/(3);\ (1)/(2))=2*3*5=30\n\nmultiply\ both\ sides\ by\ LCD=30\n\n30x+30\cdot(4)/(5)=30\cdot(2)/(3)-30x-30\cdot(1)/(2)\n\n30x+6\cdot4=10\cdot2-30x-15\cdot1\n\n30x+24=20-30x-15$

$30x+24=5-30x\ \ \ \ |subtract\ 24\ from\ both\ sides\n\n30x=-19-30x\ \ \ \ \ |add\ 30x\ to\ both\ sides\n\n60x=-19\ \ \ \ \ |divide\ both\ sides\ by\ 60\n\n\boxed{x=-(19)/(60)}$

$(x+4)/(5)=(2)/(3)-(x-3)/(6)\n\n(x+4)/(5)=(2\cdot2)/(3\cdot2)-(x-3)/(6)\n\n(x+4)/(5)=(4)/(6)-(x-3)/(6)\n\n(x+4)/(5)=(4-(x-3))/(6)\n\n(x+4)/(5)=(4-x+3)/(6)\n\n(x+4)/(5)=(7-x)/(6)\ \ \ \ |cross\ multiply$

$6(x+4)=5(7-x)\n\n6(x)+6(4)=5(7)-5(x)\n\n6x+24=35-5x\ \ \ \ \ |subtract\ 24\ from\ both\ sides\n\n6x=11-5x\ \ \ \ \ |add\ 5x\ to\ both\ sides\n\n11x=11\ \ \ \ \ |divide\ both\ sides\ by\ 11\n\n\boxed{x=1}$

Josiah and his friends are going to the movies. Each ticket costs $10, and popcorn is $5 a bag. There is a $3 service fee for the entire purchase. He has $75. If he buys 4 tickets, what is the maximum number of bags of popcorn he can buy

Answers

Make sure you check this because i do make mistakes.

10 x 4 = 40

75 - 40 = 35

So josiah has 35 dollars to spend for things other than tickets.

35 - 3 = 32 (for the service fee)

So josiah has 32 dollars to spend on popcorn

32/5 = 6.4 but you cant have half a bag of popcorn so

6 bags

Find the equation of the line that passes through the point (7,5) and is perpendicular to the line 2x - 3y=6

Answers

$(7,5);\ \ \ \ 2x - 3y=6 \ \ / subtract \ 2x \ from \ each \ side \n \n-3y = -2x + 6\ \ / divide \ each \term \ by \ (-3) \n \n y = \frac{2} {3}x -2\n \n The \ slope \ is :m _(1) = ( 2)/(3) \n \n If \ m_(1) \ and \ m _(2) \ are \ the \ gradients \ of \ two \ perpendicular \n \n lines \ we \ have \n\n\ m _(1)*m _(2) = -1$

$(2)/(3)\cdot m_(2)=-1\ \ / \cdot ((3)/(2))\n\nm_(2)=-(3)/(2)\n\nNow \ your \ equation \ of \ line \ passing \ through \ (7,5) would \ be: \n \n y=m_(2)x+b \n \n5=-(3)/(2)\cdot 7 + b \n \n 5= -(21)/(2)+b\n \nb=5+(21)/(2) \n \nb= (10)/(2)+(21)/(2)\n \nb= (31)/(2)\n\nb=15.5 \n \n y = -(3)/(2)x +15.5$

Is 8/4 equivalent to 10/5?

Answers

These are just some equivalent fractions of 8/4:

2/1 = 4/2 = 6/3 = 8/4

= 10/5 = 12/6 = 14/7 = 16/8

= 18/9 = 20/10 = 22/11 = 24/12

= 26/13 = 28/14 = 30/15 = 32/16

= 34/17 = 36/18 = 38/19 = 40/20

= 42/21 = 44/22 = 46/23 = 48/24

= 50/25 = 52/26 = 54/27 = 56/28

= 58/29 = 60/30 = 62/31 = 64/32

= 66/33 = 68/34 = 70/35 = 72/36

= 74/37 = 76/38 = 78/39 = 80/40

= 82/41 = 84/42 = 86/43 = 88/44

= 90/45 = 92/46 = 94/47 = 96/48

= 98/49 = 100/50 = 102/51 = 104/52

= 106/53 = 108/54 = 110/55 = 112/56

= 114/57 = 116/58 = 118/59 = 120/60

= 122/61 = 124/62 = 126/63 = 128/64

= 130/65 = 132/66 = 134/67 = 136/68

= 138/69 = 140/70 = 142/71 = 144/72

= 146/73 = 148/74 = 150/75 = 152/76

= 154/77 = 156/78 = 158/79 = 160/80

= 162/81 = 164/82 = 166/83 = 168/84

= 170/85 = 172/86 = 174/87 = 176/88

= 178/89 = 180/90 = 182/91 = 184/92

= 186/93 = 188/94 = 190/95 = 192/96

= 194/97 = 196/98 = 198/99 = 200/100

What is 6a squared - 12a+36

Answers

6a²-12a+36= 6a²-12a=-36
Put the normal number on the other side to have the variables on one side, and the normal number on the other.
Then group:
= 36a-12a= -36
= 24a=-36
Then isolate a:
= a=-36/24
Then simplify:
=a = - 3/2

Hope this helps!

6a² - 12a + 36 = 0
a = -(-12) +/- √((-12)² - 4(6)(36))
      2(6)
a = 12 +/- √(144 - 864)
      12
a = 12 +/- -√720
   12
a = 12 +/- -√(9 × 16 × 5)
   12
a = 12 +/- -√9 -√16 -√5
   12
a = 12 +/- (-3)(-4) -√5
   12
a = 12 +/- 12-√5
      12
a = 12 +/- 12(-2.236067978)
      12
a = 12 +/- (-26.83281573)
   12
a = 12 + (-26.83281573) a = 12 - (26.83281573)
      12       12
a = 12 - 26.83281573 a = 12 + 26.83281573
   12 12
a = -14.83281573 a = 38.832815723
   12 12
-1.236067978 a = 3.236067978

Sam is 5 years old. His older brother, Tom, is three times as old as Sam. When Sam is 20, how old will Tom be?

Answers

Sam is 5
Tom is 3 times older so 3*5=15
The difference between them is 15-5=10 years
When Sam is 20 we add the difference 20+10=30, and we have Tom's age :)
