What's the answer to: divide £48 in the ratio 7:5 (please show your working, much appreciated)
Brums [2.3K]
I can see you come from outside the USA. No insults intended!!
.
Anyways, we have to put one side of the ratio and match it to 48. 
.
Or even better...
.
MAKE!!
A!!
PROPORTION!!
.
So... Let's say 7 is proportional to 48... so 7/5 = 48/x, where x is the number equivalent to ratio of 5.
.
Cross multiply!!
<span>.
</span>7x = 240.
.
Divide 7 on both sides.
.
x = 34 2/7.
.
Hope I helped!!

1,Justin rides his bicycle 2.5 kilometers to school. Luke walks 1,950 meters to school.How much farther does Justin ride to scho
kirill [66]
1. A. 550 meters.
this is because 2.5 km = 2500 meters, since there are 1000 meters in one kilometer.
therefore, 2500 - 1950 = 550 meters.
2. B. 126 inches.
this is because there are 12 inches in one foot, so we multiply 12 by 10 since there are 10 full feet. this leaves us with 120. then, we add half a foot, which is 6 inches. therefore, it is 126 :)

Tasya [4]
To set this up you will set the two angles equal to 180° since it is a straight line
This will make the equation x+6x+19=180
Combine like terms. 7x+19=180.
Subtract 19 from both sides. This will make it 7x=161
Divide both sides by 7. That will make it x=23
Next plug in the x to solve for abc. 7(23)+19. This equals 157

X= 23

Hope this helped :)

I will mark you as brainlis if you andwer this all.

Answer: See below

Step-by-step explanation:

27.  -(a-3)

28.  (b-1)(b+3)

29.  (c+4)(c+5)

30.  d(d+5)

31.  -(3/4)(2e-5)

Sorry - I don't have time to enter the details.  Look for areas where the expressions can be factored in a manner that forms as many equivalent expressions in both the numerator and denominator.

For example:  In problem 30:

(5d-20)/(d^2+d-20) * [??]/20d = 1/4

Factor:  

  <u>(5(d-4))</u>       <u>d(d+5)</u>        = 1/4

(d-4)(d+5<u>)</u>       20d

The (d-4), d+5, and d terms cancel, leaving

5/20 = 1/4
