Does 3x-2+x+8=1/2(9x+7-x+5) have no solution or infinite solutions

Mathematics
1 answer:
kupik [55]4 years ago
6 0

Answer:

Step-by-step explanation:

3x - 2 + x + 8 = ( 9x + 7 - x + 5)/2

Add the like terms

4x + 6 = 8x + 12/2

Cross multiply or multiply both side by two

2(4x + 6) = 8x + 12

Use 2 to open the bracket

8x + 12 = 8x + 12

Collect like terms

8x - 8x = 12 - 12

0 = 0

Therefore, the equation has no solution

Find the volume of a cone with a height of 7yd and a base diameter of 6yd . use the value 3.14 for π , and do not do any roundin
yarga [219]
I think the volume of the cone is 65.94yd because the radius is 3 and the height is 7 also 3 to the second power equals 9 then 3.14 multiplied by 9 equals 28.26 and finally 28.26 multiplied by 7/3 equals 65.94

V=3.14 x r^2 h/3
V=3.14 x 3^2 7/3

Find xy if x + y=3, x^2 + y^2 = 5
Vesna [10]

Answer:

mark me

Step-by-step explanation:

x+y=3

x=3-y

putting the value of x

in this

x²+y²=5

(3-y) ²+y²=5

9-6y+y²+y²=5

2y²-6y+9-5=0

2y²-6y+4=0

2y²-4y-2y+4=0

2y(y-2)-2(y-2)=0

(2y-2) (y-2) =0

2y-2=0 or y-2=0

y=1 or y=2

so x=2 or 1

so x×y=2×1 or 1×2=2
