Answer:

p : q : r = 10 : 4 : 3

Step-by-step explanation:

Expressing the ratio in fractional form

\frac{q}{r} = \frac{4}{3} ( cross- multiply )

4r = 3q ( divide both sides by 4 )

r = \frac{3}{4} q = \frac{3}{4} × 2 = \frac{3}{2}

Then

p : q : r

= 5 : 2 : \frac{3}{2} ( multiply all parts by 2 )

= 10 : 4 : 3

Answer:

p : q : r​ =

10 : 4 : 3

Step-by-step explanation:

to make q equal in the two equations :

p : q = 5 : 2   x4

p : q = 20 : 8

q : r = 4 : 3    x2

q : r = 8 : 6

    So    p : q : r​ =

           20 : 8 :6

           10 : 4 : 3

djverab [1.8K]
In this question, there are 3 conditions that need to be met
1. The number is 3-digit
2. Hundreds digit >7 (number that will fulfill it would be 8 or 9)
3. The tens is 1 more than hundred( since the hundred possibilities is 8 or 9, then 9 in hundreds can't be used since no number higher than 9)
4. The one digit <2( that mean 0, 1)

Using the list above, you can make your possible number:

Given the functions f(x)=1x−3+1 and g(x)=1x+4+3 .
SVETLANKA909090 [29]

Answer:

The graph shifts 7 units left and 2 units up.

Step-by-step explanation:

In transformations, when a number is added or subtracted to "x" directly, that is the left/right shift.

When a number is added or subtracted outside of the "rest" of the equation, that is the up/down shift.

I learned transformations with these variables:

f(x) = \frac{a}{k(x-c)} + d

"a" - vertical stretch (a > 1) or compression (0 < a < 1)

"k" - horizontal stretch (0 < k < 1) or compression (k > 1)

"c" - translate left (+) or right (-)

"d" - translation up (+) or down (-)

The untranslated graph is centred around the origin f(x) = 1/x

f(x) begins 3 units right and 1 unit up of the untranslated graph.

g(x) is 4 units left and 3 units up of the untranslated graph.

            y

g           |

            |           f

-----------|------------ x

There is a 7 units translation left and 2 units translation up.

How do you multiply a mixed fraction by a regular fraction
Dmitriy789 [7]

Well, you first have to make the mixed fraction into an improper fraction. You then multiply the two fractions and ad the whole number into the total.

That's how i was taught back in the 4th grade... i'm not sure if it's correct but i hope it is-
