Answer:
The numbers are 2, 4, 6 and 8
Step-by-step explanation:
let the four numbers be x, y, z and l respectively
then:
x+y+z+l
(z+l)–6=4x
since they are all four consecutive even integers
then y=x+2
z=y+2=x+4
l=z+2=x+6
since (z+l)–6=4x
then ((x+4)+(x+6))–6=4x
2x+4=4x
4=4x–2x
4=2x
2=x
Answer:
False, true, true, false, false
Step-by-step explanation:
Answer:
d.
Step-by-step explanation:
if x varies directly as y,
x = ky
8 = 12k
12k = 8
k = 8/ 12
k = 2/3,
x = 2/3 y
now substitute the value of any of the numbers of each pair, and check if it works:
for e.g, find x when y = 15
x = 2/3y
x = 2/3 × 15
x = 10
since you obtain x = 10 when y = 15, the pair is a possible corresponding value of x and y. now do the same for the rest .
ii) x = 2/3y
x = 2/3 × 3, when y = 3
x = 2
hence, this is also a possible pair of x and y values.
iii) x = 2/3y
x = 2/3 × 9 when y = 9
x = 6
again, a possible pair of x and y values.
iv) x = 2/3y
x = 2/3 × 20 when y = 20
x = 40/3
here, when y = 20, x is not 15. it is 40/3.
thus, it can be determined that this is not a possible pair of x and y values.
please try to understand and have a great day!
