Answer:

C) $137.20

Step-by-step explanation:

Come up with the equation, mine looks like

2.20 x 26 + 80 = a

And then solve.

a = 137.20

(btw a is just a random variable, it could've been y or even x)

Solve the equation 4s2+32s=60 by completing the square

lord [1]

Answer:

s = -4 ± √31

Step-by-step explanation:

Given 4 $s^{2}$ + 32s = 60

divide by 4 throughout

$s^{2} + 8s = 15\\s^{2} + 8s + (\frac{8}{2}) ^{2} = 15 + (\frac{8}{2}) ^{2}$

$(s + 4)^{2} = 31\\s + 4 = \sqrt{31}$

s = -4 ± √31

What is greater one seventh or one nineth

Anton [14]

Method 1:

Look at the picture.

$\dfrac{1}{7}$ is greater than $\dfrac{1}{9}$

$\boxed{\dfrac{1}{7}>\dfrac{1}{9}}$

Method 2:

Find the common denominator:

multiples of 7: 0, 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, ...

multiples of 9: 0, 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, ...

63 = 7 · 9

$\dfrac{1}{7}=\dfrac{1\cdot9}{7\cdot9}=\dfrac{9}{63}\\\\\dfrac{1}{9}=\dfrac{1\cdot7}{9\cdot7}=\dfrac{7}{63}$

$\dfrac{9}{63} > \dfrac{7}{63}$

therefore

$\dfrac{1}{7} > \dfrac{1}{9}$
