Answer:

5/4

Step-by-step explanation:

To divide 10/12 by 4/6, invert the divisor (4/6) and multiply the result:

10 6

------- * ------ = 10/8 = 5/4

12 4

Komok [63]

-4 = y + 3

y = -4x - 3

Solve for Y in the first equation:

-4 = y +3

Subtract 3 from both sides:

y = -7

Now using the addition method:

rewrite the second equation as 4x+y = -3

Multiply y = -7 by - 1 to get -y = 7

Now add the two together:

4x +y = -3

-y =7

4x = 4

Divide each side by 4:

x = 4/4 = 1

Then replace x in one of the equations to solve for y which is -7

X = 1, Y = -7

Whates 2 divided by 3 z= -6

GalinKa [24]

z = 20/3 = 6.667

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

2/3-(z-6)=0

Step by step solution :

Step 1 :

Simplify —

Equation at the end of step 1 :

— - (z - 6) = 0

Step 2 :

Rewriting the whole as an Equivalent Fraction :

2.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 3 as the denominator :

z - 6 (z - 6) • 3

z - 6 = ————— = ———————————

1 3

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

2 - ((z-6) • 3) 20 - 3z

——————————————— = ———————

3 3

Equation at the end of step 2 :

20 - 3z

——————— = 0

Step 3 :

When a fraction equals zero :

3.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

20-3z

————— • 3 = 0 • 3

Now, on the left hand side, the 3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

20-3z = 0

PLEASE HELP ME!!!!!!!!!

artcher [175]

In the right triangle, one of the angles has measure 60 deg, so the remaining angle has measure 30 deg. In such a 30-60-90 triangle, the sides occur in a ratio of 1 to $\sqrt3$ to 2 (shorter leg to longer leg to hypotenuse). This means

$2n=4\implies n=2$

$n\sqrt3=m\implies m=2\sqrt3$

making the answer C.

I have a problem in math. I have to figure out how to tell their similar through scale factor, to prove their similar, I don't k

sammy [17]

Answer:

see explanation

Step-by-step explanation:

If the ratios of the 3 pairs of corresponding sides of the 2 triangles are equal , then the triangles are similar (SSS postulate )

the3 ratios of the 2 triangles , left to right are all equal to

$\frac{3}{4}$

Then the triangles are similar by the SSS postulate

the corresponding angles of similar triangles are congruent, then

∠ c = 60°

Also both triangles have 3 congruent sides and are therefore equilateral triangles with all angles equal to 60°, so

c = 60°
