Mathematics
1 answer:
lara31 [8.8K]3 years ago
5 0

Answer:

It is D.

Step-by-step explanation:

Combine:

4x-7=2x-3

Solve, subtract 2x on both sides:

4x-2x-7=2x-2x-3

2x-7=3

Add 7 on both sides:

2x-7+7=3+7

2x=10

Divide 2 on both sides:

x=5

Plug in the x value in each equation:

4(5)-7=13

2(5)-3=7

Now plug in into the equation

(13×4)(4)

52/4=13

It is D.

for two positive integers a and b, we know g c d (a comma b )equals 15 comma space l c m (a comma b )equals 90, what is a b?
Scilla [17]

Two positive integers have gcd (a, b) = 15 and lcm (a, b) = 90. Those two numbers are 15 and 90 or 30 and 45.

Suppose we have 2 positive integers, a and b, then:

gcd (a, b) = the greatest common divisor = common prime factors of a and b

lcm (a, b) = the least common multiple = multiplication of the greatest common prime factors of a and b

In the given problem:

gcd (a, b) = 15

prime factorization of 15:

15 = 3 x 5

Hence,

a = 3 x 5 x ....

b = 3 x 5 x ....

lcm (a, b) = 90

prime factorization of 90:

90 = 3 x 5 x 2 x 3

Therefore the possible pairs of a and b are:

Combination 1:

a = 3 x 5 = 15

b = 3 x 5 x 2 x 3 = 90

Combination 2:

a = 3 x 5 x 2 = 30

b = 3 x 5 x 3 = 35

We can conclude the two integers are 15 and 90 or 30 and 45.
