Joseph had 7 1/4 ounces of candy to share with his friends. He gave them 2 4/5 ounces of candy when they came over to play video
OleMash [197]
7 1/4 - 2 4/5
Turn the denominator into a common denominator for both fractions:
7 5/20 - 2 16/20
To subtract easier, turn the fractions into an improper fraction:
145/20 - 56/20
Subtract the numerators:
145 - 56 = 89 ---> 89/20
Simplify (to get an answer of):
4 9/20 
Add labels:
Joseph has 4 9/20 ounces of candy left

Solve for x " 1/6x+2/3x+4=x+2
Anuta_ua [19.1K]

Answer:

x = 12

Step-by-step explanation:

Solve for x:

(5 x)/6 + 4 = x + 2

Put each term in (5 x)/6 + 4 over the common denominator 6: (5 x)/6 + 4 = (5 x)/6 + 24/6:

(5 x)/6 + 24/6 = x + 2

(5 x)/6 + 24/6 = (5 x + 24)/6:

(5 x + 24)/6 = x + 2

Multiply both sides by 6:

(6 (5 x + 24))/6 = 6 (x + 2)

(6 (5 x + 24))/6 = 6/6×(5 x + 24) = 5 x + 24:

5 x + 24 = 6 (x + 2)

Expand out terms of the right hand side:

5 x + 24 = 6 x + 12

Subtract 6 x from both sides:

(5 x - 6 x) + 24 = (6 x - 6 x) + 12

5 x - 6 x = -x:

-x + 24 = (6 x - 6 x) + 12

6 x - 6 x = 0:

24 - x = 12

Subtract 24 from both sides:

(24 - 24) - x = 12 - 24

24 - 24 = 0:

-x = 12 - 24

12 - 24 = -12:

-x = -12

Multiply both sides of -x = -12 by -1:

(-x)/(-1) = 12

(-1)/(-1) = 1:

Answer:  x = 12

Write the equation in standard form of a circle with center (-7,2), tangent to the y-axis.
DerKrebs [107]

Answer:

(x+7)^{2}+ (y-2)^{2}=49

Step-by-step explanation:

It is given that circle is a tangent to y axis, which tells us that the distance between the centre point and y axis is the radius of the triangle.

Formula for equation of circle with centre (x1,y1) and radius r is

(x-x1)^{2}+ (y-y1)^{2}=r^{2}

In the given case distance between the centre and y axis is 7 units so radius would be 7 and the centre point is (-7,2),

the equation of circle is ,

(x+7)^{2}+ (y-2)^{2}=7^{2}

(x+7)^{2}+ (y-2)^{2}=49

Hence the abow equation is the circle equation.
