a tiger can eat food that weighs up to about 15% of it's body weight if a tiger can eat 75 lbs of food how much does a tiger wei

allsm [11]

75lbs of food = 15% tiger's food weight
?lbs tiger= 100% tiger's body weight

So you want to take the amount of food (75lbs), divide it by the amount of the tiger's food weight (15%) and then multiply it by it's total body weight (100%)
So 75 / 15 = 5
and 5 x 100 = 500
so the tiger = 500lbs

Simplify completely: the quantity 8 times x to the third power plus 6 times x to the 2nd power minus 4 times x all over negative

True [87]

The answer is <span>a.−4x^2 − 3x + 2
</span>
the quantity 8 times x to the third power plus 6 times x to the 2nd power minus 4 times x all over negative 2 times x is: $\frac{8 x^{3}+6 x^{2} -4x }{-2x}$

$\frac{8 x^{3}+6 x^{2} -4x }{-2x} = -\frac{8 x^{3}+6 x^{2} -4x }{2x}=- \frac{2x*4 x^{2} +2x*3x-2x*2}{2x} =- \frac{2x(4x^{2} +3x-2)}{2x} = \\ \\ =-(4x^{2} +3x-2)=-4x^{2} -3x+2$

Show work please and thanks!

7x+1 + 4x-3 = 42
11x-2=42
11x=44
Divide by 11 on both sides which equals:
x=4
To find the length of DE just plug 4 in for x into the equation:
(7x+1) —> 7(4)+1= 29
29 is the length of DE
Then plug in 4 to EF’s equation:
(4x-3) —> 4(4)-3=13
13 is the length for EF
29+13= 42
So in the end, your answer will be 29.
