Write an equivalent multiplication expression. than, find the quotient in it's simplest form. Use a model to support your respon

ludmilkaskok [199]

Answer:

Part 1) $\frac{1}{8}$

Part 2) $\frac{1}{9}$

Step-by-step explanation:

we know that

The quotient of a fraction by a whole number is the same that multiply the fraction by the reciprocal of the whole number

$\frac{\frac{a}{b}}{c}=(\frac{a}{b})(\frac{1}{c})$

Part 1) 1/4 divided by 2

$\frac{\frac{1}{4}}{2}=(\frac{1}{4})(\frac{1}{2})=\frac{1}{8}$

Part 2) 2/3 divided by 6

$\frac{\frac{2}{3}}{6}=(\frac{2}{3})(\frac{1}{6})=\frac{2}{18}$

Simplify

$\frac{1}{9}$

-6x + 5y = 1<br> 6x + 4y = –10

Firlakuza [10]

Answer:

x=-1

y=-1

Step-by-step explanation:

-6x + 5y =1 ......equation (1)

6x + 4y = –10 ......equation (2)

adding equation (1) to equation (2)

9y=-9

9y/9 =-9/9 (dividing both side by the coefficient of y)

y=-1

subtituting the value of y =-1 into equation (2)

6x+4(-1)=-10

6x+(-4)=-10

6x-4=-10

6x=-10+4(making constant to be at one side and the variable at the other side)

6x=-6

x=-6/6

x=-1

Chang knows one side of a triangle is 13 cm. Which set of two sides is possible for the lengths of the other two

Ludmilka [50]

Answer:

8 cm and 9 cm

Step-by-step explanation:

Hi there!

The sum of the lengths of two sides of a triangle must <em>always be greater</em> than the length of the third side.

5 cm and 8 cm ⇒ 5+8=13; not greater than 13

6 cm and 7 cm ⇒ 6+7=13; not greater than 13

7 cm and 2 cm ⇒ 7+2=9; not greater than 13

8 cm and 9 cm ⇒ 8+9=17; greater than 13

Therefore, the last set of two sides is possible for the lengths of the the other two sides of this triangle.

I hope this helps!
