Write two expressions that could be used to find 105% of x. ANSWER TODAY!! :) thanks
Margaret [11]

First way: x * 1.05

This computes directly what 105% of x will be.


Second way: x + (x * 0.05)

This takes x (which is 100%) and adds 5% of x to it.

Solve<br> h-w<br> Solve m = for the<br> 8<br> variable h.<br> I
Ilya [14]

Answer:

1) m = h - w/8

Subtract h from both sides.

m - h = -w/8

Subtract m from both sides.

-h = -m - w/8

Divide all terms by -1.

h = m + w/8.

2) m = h - w/8

Get rid of the denominator 8 by multiplying 8/1 to all terms.

8m = 8h - w

Add w on both sides and subtract 8m from both sides.

w = 8h - 8m

3) w = x + y/z

Get rid of the denominator z by multiplying it to all terms.

wz = xz + y

Subtract xz from both sides of the equation.

wz - xz = y OR y = wz - xz

4) w = x + y/z

Subtract x from both sides.

w - x = y/z

Get rid of the denominator by multiplying it to all terms.

wz - xz = y

Now factor the expression wz - xz.

z(w - x) = y

Divide both sides by w - x.

z = y / w - x

This is read as z equals to y divided by w minus x.

5) The area of a triangle is A = 1/2bh

First, get rid of the denominator by multiplying both sides by 2.

2A = bh

To find b, divide both sides by h.

2A/h = b

6) P = kt/v

Multiply both sides by v.

Pv = kt

Divide both sides by t.

Pv/t = k OR k = Pv/t.

The number of mosquitoes in Brooklyn (in
stealth61 [152]

Answer:

Maximum is 4

Step-by-step explanation:

M(x) is quadratic function, so we need to fin maximum.

m(x)=-x(x-4)

m(x)=-x^2+4x

To find a maximum we need to find m’

M’(x)=-2x+4

M’(x)=0 if x=2

The maximum is in the point x=2

M(2)=-2(2-4)=4
