Express x as the subject of the formula​

Mathematics
1 answer:
Slav-nsk [51]3 years ago
5 0

Answer:

(a).y=5z+x

this isn't a problem, just flip x to the other side

so x = 5z-y

(b). b=x/2a

cross multiply

x = b×2a

x= 2ab

c.8d=cx

divide both sides by c

8d/c=cx/c

x=8d/c

d.3px=12q

divide both sides by 3p

3px/3p=12q/3p

x=12p/3q

e. 4x=m/3-n

cross multiply

4x × 3 = m-n

12x = m-n

divide both sides by 12

12x/12=m-n/12

x = m-n/12

How do you solve the proportion7/5=x/3 ??
mote1985 [20]
The way I like to solve proportions is by cross multiplying and dividing. First yo multiply the diagonals and then you divide by the other number. So if your proportion is 7/5 = x/3, your equation would be 7*3/5.  So 7*3 is 21, so your equation is now 21/5.  With some long division, you'll see that 21/5 = 4.2  That's your answer, feel free to ask more questions if you need!!(:
