Answer:
2.5
Step-by-step explanation:
The equation will have infinite solutions when it is a tautology--when both sides say exactly the same thing.
Eliminate parentheses, match coefficients, and solve for b.
ax +ab = 4x +10
a = 4 . . . . . . coefficient of x
ab = 10 . . . . constant
Since we know a, we can find b:
4b = 10
b = 10/4 . . . . . . . divide by 4
b = 5/2 = 2.5 . . .express in your favorite form
Answer:
choice f
Step-by-step explanation:
take ∆ abc
ab^2 = ac^2 + ab^2
400 = 225 + ab^2
ab =√ 175
∆aDB
bd = 20-x
ad^2 = 175 -(20-x)^2
∆acd
225 = x^2 + 175 - 400+ 40x - x^2
225 = -225 + 40x
450 = 40x
x = 45/4
Answer:3.6364
Step-by-step explanation:
Because the 0 isn’t worth nothing & so the 4 stays the same
Answer: The least common multiple of 4 and 6 is 12 because this is the smallest positive integer that is divisible by both 4 and 6.
Step-by-step explanation:
- The least common multiple of two integers m and n is the least positive integer that is divisible by both m and n.
We are given that :
The first five multiples for the numbers 4 and 6 are shown below.
We can see that from the multiples of 4 and 6 , the least common multiple of 4 and 6 =12 such that 12 is divisible by 4 and 6 .
