2 consecutive even integers : x and x + 2

4(x) + 3(x + 2) = 20
4x + 3x + 6 = 20
7x + 6 = 20
7x = 20 - 6
7x = 14
x = 14/7
x = 2

x + 2 = 2 + 2 = 4

so ur first number (x) = 2 and ur second number (x + 2) = 4

What is the ratio of 364:78
Klio2033 [76]
You'd want to simplify that by dividing both terms by the greatest common factor which is the product of the shared primes of both numbers prime factorization...

364=2*2*7*13, 78=2*3*13, so the GCF is 2*13=26, now divide both terms by 26

In NEED OF HELP! SO Frustrating!
vitfil [10]

ja, yo is correct, just expand that formula with your calculator

each one is 5% bigger than pevious

each one=previous+previous*5%

each one=previous*1+previous*0.05

each one=previous*(1+0.05)


each one is 1.05 times of previous

so after n years, if today year size is P then

A=P(1.05)^n

A=final size

so ya, after 18 years, n=18 so you get

A=859(1.05)^{18}

A=2067.29 microliters
