3(s-5)/4 -3 = 4s- (s-3)/2<br>pls answer fast​
Jobisdone [24]

Answer:

s =  \frac{9± \sqrt{ - 39} }{4}

Step-by-step explanation:

\frac{3(s - 5)}{4 - 3}  =  \frac{4s \times (s - 3)}{2}

➡️ \frac{3(s - 5)}{1}  = 2s \times (s - 3)

➡️ 3s - 15 = 2 {s}^{2}  - 6s

➡️ 3s - 15  -  2 {s}^{2}  + 6s = 0

➡️ 9s - 15 - 2 {s}^{2}  = 0

➡️ - 2 {s}^{2}  + 9s - 15 = 0

➡️ 2 {s}^{2}  - 9s + 15 = 0

➡️ s =  \frac{ - ( - 9)± \sqrt{( - 9 {)}^{2}  - 4 \times 2 \times 15} }{2 \times 2}

➡️ s =  \frac{9± \sqrt{81 - 120} }{4}

➡️ s =  \frac{9± \sqrt{ - 39} }{4}

➡️ s∉ℝ

The following set of coordinates represents which figure? (1, 1), (5, 3), (7, 7), (3, 5) (4 points)
slamgirl [31]
Check the slopes 
the first 2 points have slope (3-1) / (5-1) = 2/4  = 1/2
points 2 and 3 slope =  4/2 = 2
3 and 4:- slope = -2/-4 = 1/2
4 and 1:- slope =  4/2 = 2

so we have 2 pairs of opposite sides which are parallel

looks like a parallelogram or a rhombus 

if adjacent sides are equal its a rhombus

length betwee  pts 1 and 2  = sqrt(2^2 + 4^2) = sqrt20
 .. ...  ...   ..  ..   .. ...2 and 3 =  sqrt(4^2 + 2^2) = sqrt20

so it is a rhombus

William has a 26 -liter glass tank. First, he wants to put some marbles in it, all of the same volume. Then, he wants to fill th
Ann [662]

Answer: 0.06 litre or 60 ml


Step-by-step explanation:

Given: The capacity of glass tank= 26 liter

If he add 20.9 liters of water after 85 marbles to fill it completely, then

The volume of 85 marbles= 26-20.9=5.1\ liters

Since, the marbles have same volume.

∴ Volume of each marble= \frac{\text{volume of 85 marbles}}{\text{85}}

⇒ Volume of each marble=\frac{5.1\ litre}{85}=0.06\ liters

In milliliters, Volume of each marble=0.06\times1000=60ml
