Simply -3 3/4 divided by 2 1/2

Dima020 [189]

Answer:

$=-1\frac{1}{2}$

Step-by-step explanation:

Given the following question:

$-3\frac{3}{4} \div2\frac{1}{2}$

In order to find the answer, we first convert the mixed numbers into improper fractions. Then we use KCF (Keep, Change, Flip) and solve.

$-3\frac{3}{4} \div2\frac{1}{2}$
$-3\frac{3}{4} =12+3=-\frac{15}{4}$
$2\frac{1}{2}=2\times2=4+1=\frac{5}{2}$
$-\frac{15}{4} \div\frac{5}{2}$
$-\frac{15}{4} \times\frac{2}{5}$
$15\times2=30$
$4\times5=20$
$=-\frac{30}{20}$
$-\frac{30}{20} \div10=-\frac{3}{2}$
$-\frac{3}{2}=3\div2=-1\frac{1}{2}$
$=-1\frac{1}{2}$

Hope this helps.

A truck traveled 205 miles in 3/12 hours. The distance is the product of the rate and the time. To the nearest tenth, what is th

Rufina [12.5K]

Distance = rate*time, or

distance = (average speed)* time, so

average speed = distance/ time.

average speed = 205 mi / (3/12) h = 205 mi/ (1/4)h = 205*4 mi/h=

= 820 mi/h

It is looks to high for speed of the truck,

probably time should be 3.12 h,

then

average speed = 205 mi / (3.12) h ≈ 65.71 mi/h.

That looks close to real life.

Y=-2x-5<br> y=5x+6<br> Round to the nearest hundredth.

yuradex [85]

Step-by-step explanation:

-2x-5=5x + 6

-2x - 5x = 6 + 5

-7x = 11

x = -11/7

x = 1.571

y = 5(1.571) + 6

y = 7.855 + 6

y = 13.855
