Combine like terms
2x^2 + -7x^2 = -5x^2
-9x + 4x = -5x
3 + -2 = 1
put back together
-5x^2 - 5x +1

The school want to purchase enough tarp material to cover their field during bad weather. They want to get exactly eleven percen

KonstantinChe [14]

Answer:

6660 yards^2

Step-by-step explanation:

Assumption: the field is 120 yards long and 50 yards wide.

First calculate the area of the field: 120*50 = 6000 yards^2

Then, calculate the 11% of that area: 6000 yards^2*11/100 = 660 yards^2

Finally, the area of the tarp material should be 6000 yards^2 + 660 yards^2 = 6660 yards^2

PLEASE HELP IMMEDIATELY

MissTica

Answer:

Option B is the correct option.

Step-by-step explanation:

$- \frac{1}{2} + x = - \frac{21}{4}$

Move constant to R.H.S and change its sign:

$x = - \frac{21}{4} + \frac{1}{2}$

Take the L.C.M

$x = \frac{ - 21 + 1 \times 2}{4}$

$x = \frac{ - 21 + 2}{4}$

Calculate

$x = - \frac{19}{4}$

Hope this helps...

Good luck on your assignment..

The circumference of the top of the cake is $9.5\pi\approx29.845$ in.

It sounds like the baker is trying to line the circumference with cherriesto fit as many as possible along the border, like in the picture I've attached below.

This comes down to dividing the cake's circumference by the diameter of each cherry:

$\dfrac{9.5\pi}{0.75}\approx39.79$

or about 39 cherries, making the answer D.
