Answer:
there is no solution for x
Step-by-step explanation:
BTW you can use math.way
for the equation <em>5x−7y=58 </em> for <em><u>x</u></em>=7/5y+58/5 for <em><u>y</u></em> 5/7x+−58/7
for the equation y=−x+2 x= −y+2 for y= −x+2
Answer:
A: (9, 6)
B: (3, 6)
C: (9, -3)
D: (3, -3)
Step-by-step explanation:
Multiply all x and y values by 1.5.
Answer
7.5 pounds
Step-by-step explanation:
Since adding x grams of salt will bring th percentage of the salt to 25
Hence. 10% of the 50 gram gives. 5 gram initial salt before it is added.
5+ x/ 50 * 100= 25/
5+x /50 = 0.25
5+x = 12.5
X= 12.5- 5
X= 7.5pounds
Answer:
The correct answer will be "0.756596 m²".
Step-by-step explanation:
The given values are:
The radius of an umbrella,
r = 0.4 m
The height of an umbrella,
h = 0.45 m
As we know,
The lateral surface of an umbrella will be:
⇒ ![\pi r\sqrt{r^2+h^2}](https://tex.z-dn.net/?f=%5Cpi%20r%5Csqrt%7Br%5E2%2Bh%5E2%7D)
On substituting the values, we get
⇒ ![\pi \times 0.4\sqrt{(0.4)^2=(0.45)^2}](https://tex.z-dn.net/?f=%5Cpi%20%5Ctimes%200.4%5Csqrt%7B%280.4%29%5E2%3D%280.45%29%5E2%7D)
⇒ ![0.756596 \ m^2](https://tex.z-dn.net/?f=0.756596%20%5C%20m%5E2)
So that the amount of fabric needed will be "0.756596 m²".
