Find two numbers given that their sum is 60 and

likoan [24]

Answer:

12 and 48

Step-by-step explanation:

let n be the larger number , then $\frac{1}{4}$ n is the smaller number and their sum is

x + $\frac{1}{4}$ x = 60 ( multiply through by 4 to clear the fraction )

4x + x = 240 , that is

5x = 240 ( divide both sides by 5 )

x = 48

smaller number = $\frac{1}{4}$ × 48 = 12

The 2 numbers are 12 and 48

Use the change of Base formula to evaluate log5 92 . then convert. Log5 92 to a logarithm in base 3. Round to the nearest thousa

vovikov84 [41]

Change of base is
$log_a(b)= \frac{log_c(b)}{log_c(a)}$
change base to 3
$log_5(92)= \frac{log_3(92)}{log_3(5)}$
why would you want base 3? base 10 is on most calculators
anyway, the value would be 2.809555

Graph the image of the given triangle under a dilation with a scale factor of 1/2 and center of dilation (0, 0) .

Irina-Kira [14]

Vertices of the given triangle are: (0, 0) , (8, 0) and (-6, 0)

If we dilate the triangle with a scale factor of 1/2 , then the new vertices will be...

$(0*\frac{1}{2}, 0*\frac{1}{2} )= (0,0)$

$(8*\frac{1}{2}, 0*\frac{1}{2} )= (4,0)$

$(0*\frac{1}{2}, -6*\frac{1}{2} )= (0,-3)$

Now we will just plot those vertices for getting the dilated triangle.

Help asap my last question GIVING BRAINLIST!!!!

Alex

Answer:

1) $x < 0$

2) $x > 0$

3) $x < 10$

4) $x < -\frac{31}{55}$

5) $x \geq 0$

6) $x \geq -1$

Step-by-step explanation:

1) $-3 > 2x -3$

$2x- 3 < -3$

$2x - 3 + 3 < -3 +3$

$2x < 0$

$\frac{2x}{2} < \frac{0}{2}$

$x < 0$

2) $5 > -x + 5$

$-x + 5 < 5$

$- x + 5 -5 < 5 - 5$

$-x < 0$

$\frac{-x}{-1} < \frac{0}{-1}$

$x > 0$

3) $\frac{x}{5} -2 < 0$

$5 \times (\frac{x}{5} - 2 ) \times 5 < 0$

$x - 10 < 0$

$x -10 + 10 < 0 +10$

$x < 10$

4) $-5x + 11 > 31$

$-5x \cdot 11 < 31$

$-55x < 31$

$\frac{-55x}{-55} > \frac{31}{-55}$

$x < -\frac{31}{55}$

5) $\frac{1}{2}x - 4 \geq -4$

$\frac{1}{2}x -4 +4 \geq -4 +4$

$\frac{1}{2}x \geq 0$

$\frac{\frac{1}{2}x }{\frac{1}{2} } \geq \frac{0}{\frac{1}{2} }$

$x \geq 0$

6) $-4x + 2 \leq 6$

$-4x +2 - 2 \leq 6 -2$

$-4x < 4$

$\frac{-4x}{-4} \leq \frac{4}{-4}$

$x \geq -1$
