Hello from MrBillDoesMath!
Answer: x = 7/10
Discussion:
To eliminate fractions multiply each side by 10:
10 ( 9/5x - 2/5 ) = 10 * ( 8x +3)/10 or
10 * ( 9/5)x - 10 *(2/5) = 8x + 3 or
9 *2 x - 2*2 = 8x +3 or
18x - 4 = 8x + 3. Subtract 8x for each side:
18x - 8x - 4 = (8x - 8x) + 3 or
10x -4 = 0x + 3 or
10x -4 = 3 or
10x = 7
x = 7/10
Thank you,
MrB
First, we will get rid of the brackets
2v+46 = 8v-8
then, we will gather the terms with the variables on one side of the equation and the terms with no variables on the other side.
46+8 = 8v-2v
54 = 6v
to get the value of v, we will divide both sides of the equation by 6
v = 54/6 = 9
Answer:
NVM MY BAD
x=19
quadrilateral have the internal degree sum of 360
not 365
Answer: D
Step-by-step explanation:
• To dilate by a factor of 1/2 is the same as “multiplying by 1/2” or “dividing by 2”.
• point R is at coordinate (6,4)
• 6 divided by 2= 3
• 4 divided by 2= 2
Giving you (3,2)
Formula for dilating by a factor of 1/2:
(X divided by 2, Y divided by 2)
The correct answer would be B because 88 divided by 11 would be 8 and therfore it would justift that the ration would be equal to 88:33
