Answer:

(8x - 14)  + (2x + 54) = 180 \\ 8x + 2x - 14 + 54 = 180 \\ 10x - 14 + 54 = 180 \\ 10x + 40 = 180 \\ 10x = 180 - 40 \\ 10x = 140 \\ x =  \frac{140}{10}  \\ x = 14

Write each expression below in radical form and compute the value without using a calculator.
gregori [183]

Assuming that an exponentiation sign is missing, all you need to know is that rational exponents work like this:

a^{\frac{b}{c}}=\sqrt[c]{a^b}

So, you have

25^{\frac{5}{2}}=\sqrt{25^5}=\sqrt{(5^2)^5}=5^5

And similarly,

81^{\frac{7}{4}}=\sqrt[4]{25^7}=\sqrt[4]{(3^4)^7}=3^7

Pls help I’ll brainlest for correct answer you gotta graph it on the graph too
Ipatiy [6.2K]

Answer:

Slope: -2/3

Y Intercept: 0,-3

Step-by-step explanation:

To find the slope, use the formula (y1-y2)/(x1-x2)

(1-(-1))/(-6-(-3))

-2/3

So the slope is: -2/3

If the slope is 3/2, then the using the formula of y=mx+b, we can find the y intercept (b)

y = -2/3x + b

insert any point of x and y

-1 = -2/3(-3)+b

-1=-2+b

so b = -3

thus, the Y intercept is 0,-3

The standard guidelines for fluid intake recommend that a 10dash​20-kg child should have 1000 mL of fluid plus 50 mL for each fu
yarga [219]
Given that the <span>standard guidelines for fluid intake recommend that a 10 - 20 kg child should have 1000 mL of fluid plus 50 mL for each full kilogram of body weight over 10 kg per day.

1 ounce contains 29.57 mL of fluid, thus an 8-ounce glass contains 8(29.57) = 236.56 mL of fluid.

1 pound is equivalent to </span>0.45 kg, thus, 43 pound is equivalent to 43(0.45) = 19.35 kg

Thus, the <span>standard guidelines for fluid intake recommend for a 43 pounds (19.35 kg) child is given by 1000 + 9(50) = 1000 + 450 = 1450 mL of fluid per day.

Therefore, the number of 8-ounce glasses a 43 pound child should have is given by:

</span>\frac{1450}{236.56} =6.13\approx6\ glasses<span>
