Answer:

$9x + 7$

Step-by-step explanation:

$6x + 5y + 3x + 7 - 5y \\ = 6x + 5y + 3x + 7 + ( - 5y)$

Combine like terms,

$(6x + 3x) + (5y + ( - 5y)) + (7) \\ 9x + 7$

Hope this will help you :))

Answer:

9x + 7

Step-by-step explanation:

Given

6x + 5y + 3x + 7 - 5y ← collect like terms

= (6x + 3x ) + (5y - 5y ) + 7

= 9x + 0 + 7

= 9x + 7

Find the circumference of the circle with 1/4 Pi square centimetre square 2

otez555 [7]

Answer:

The circumference of the circle is 6 cm (approximately).

Step-by-step explanation:

Given:

Area of the circle = 1/4π²

Now, to get the circumference of the circle we need the radius.

So, finding the radius by putting the formula of area:

Area = $\pi r^{2}$

$\frac{1}{4} \pi ^{2}$ = $\pi r^{2}$

dividing π by both sides:

$\frac{1}{4}\pi$ $=r^{2}$

using square root on both the sides:

$\frac{1}{2}\sqrt{\pi } = r$

So, the radius is $\frac{1}{2}\sqrt{\pi }$

Now, putting the formula of circumference:

$circumference=2\pi r$

= $2\pi\frac{1}{2} \sqrt{\pi}$

= $\pi \sqrt{\pi}$

putting the value of π =3.14

= $3.14\times\sqrt{3.14}$

= $3.14\times1.77$

= $5.56$

Circumference = 5.56 cm

Therefore, the circumference of the circle is 6 cm (approximately).

Amelia and Jayden work at a furniture store. Amelia is paid $185 per week plus 9.5% of her total sales in dollars, xx, which can

almond37 [142]

Answer:

The weekly sales must be $12,600

Step-by-step explanation:

if their pay is the same, the equations have to be equal

amelia = jayden

185 +.095x = 311 +.085x

subtract .085x from each side

185 +.095x-.085x = 311 +.085x-.085x

185+.01x = 311

subtract 185 from each side

185-185+.01x = 311-185

.01x = 126

divide by .01

.01x/.01 = 126/.01

x = 12600
