Answer:

f=1

Step-by-step explanation:

Let start off with doing -f plus 4f which gives you 3f. The equation would now be 2+3f=8-3f. Add 3f so you can cancel out the -3f and add the 3f to the other 3f. Now your equation is 2+6f=8. Cancel out do by doing -2. (Don't forget to to it to the 8 also.) Now your equation is 6f=6. Divide 6 from both sides to get 1. (You divide because you want to get f alone.

Solve for w. 5w + 9z = 2z + 3w w = z w = z w = –2z w = –7z

In-s [12.5K]

We have been given an equation and we are asked to find value of w from our given equation.

$5w+9z=2z+3w$

First of all we will subtract 3w from both sides of our equation.

$5w-3w+9z=2z+3w-3w$

$5w-3w+9z=2z$

Now let us subtract 9z from both sides of our equation.

$5w-3w+9z-9z=2z-9z$

$5w-3w=2z-9z$

$(5-3)w=(2-9)z$

$2w=-7z$

Now let us divide both sides of our equation by 2.

$\frac{2w}{2}= \frac{-7z}{2}$

Upon cancelling 2 from left side of our equation we will get,

$w=\frac{-7}{2} z$

Therefore, we can see that $w=\frac{-7z}{2}$ .

A pair of flip flops is labeled $9 on the price tag. At the register, I paid $9.45. What percent of $9 is $0.45?

Diano4ka-milaya [45]

5% of 9 is 0.45.

Why? Well 0.45 times 20 is equal to 9, and 100 divided by 20 is 5 therefore 5 percent.

Fie triunghiul ABC isoscel cu AB=AC=3 cm daca mediatoarea laturi AC intersectat cu latura BC in M si perimetrul thriunghiului AM

NemiM [27]

Answer:

MC = 4.5cm

Step-by-step explanation:

Question:

Let the isosceles triangle ABC with AB = AC = 3 cm. if the mediator of the sides AC intersects with the side BC in M and the perimeter of the triangle AMC = 12 cm. Calculate MC.

Solution:

Find attached the diagram used in solving the question.

Given:

∆ABC is an isosceles triangle (two sides and angles are equal)

AB = BC = 3cm

Perimeter of ∆AMC = 12cm

From the diagram, M cuts AC at the the middle.

AD = CD = AC/2 = 3/2

Perimeter of Right angled ∆AMD = AM + AD + MD

= 3/2 + AM +MD

Perimeter of Right angled ∆CMD =CM + CD + MD

= 3/2 + CM +MD

Right angled ∆AMD = Right angled ∆CMD

CM = AM

Therefore ∆AMC is an isosceles triangle

CM = AM (two sides of an isosceles triangle are equal)

Let CM = AM = x

Perimeter of ∆AMC = AM + CM + AC

12 = x + x + 3

12 = 2x + 3

2x = 12-3

2x = 9

x = 9/2 = 4.5

CM = AM = 4.5cm

MC = CM = 4.5cm
