Find the LCM of 40a2b and 48ab4.
Answer:
Step-by-step explanation:
40a²b = 2* 2 * 2 * 5 * a² * b = 2³ * 5 * a² * b
48ab⁴ = 2 * 2 * 2 * 2 * 3 * a *b⁴ = 2⁴ * 3 * a * b⁴
LCM = 2⁴ * 3 * 5 * a² * b⁴
= 16 * 3 * 5 * a² * b⁴
= 240a²b⁴
which of the following shows the solution to the inequality
Answer:
I got x = 1
Step-by-step explanation:
First to isolate the variable you add 3 to both sides which will give you 1/2x is less than or equal to 2. Then divide both sides by 1/2 and you will get x = 1. To check the answer I just did:
[tex]1/2(1) -3 \leq -1\\1/2 -3\leq -1\\-2.5\leq -1[/tex]
And since -2.5 is less than -1 this statement is true. x does in fact equal 1
Please help marking brainliest if correct!!
Answer:
Step-by-step explanation:
2x=5x+60.
0=3x+60 ( subtract 2x from both sides)
-60=3x(subtract 60 on both sides)
x=-20

Answer:
gidetgfddtgfft5f5f5f5d5f6guhuhug5xtdrd4s4d5d6v7g7h8n8b7v6v6
Answer:
Let J represent the number of tickets Jose sells. Let M represent the number of tickets Mark sells. Make equations, if Mark sells 15 more tickets than Jose, the equation is J+15=M. Because we know that in between both of them they sell 63 raffle tickets, then M+J=63. Now plug in the value of M (J+15) into M+J=63. And you get (J+15)+J=63, which is 2J+15=63. Subtract 15 from both sides and get 2J=48. Now divide 48 by 2, J=24. So now you know Jose sold 24 tickets, and to find how many Mark sold, plug in 24 into J+15=M and get 24+15=M where M is 39. Now check, 24+39=63. So Mark sold 39 tickets and Jose sold 24.

In Triangle ABC, angle A measures 40 degrees. Give possible angle measures for B and C.
Answer:
B = C = 70°
Step-by-step explanation:
In Triangle ABC, angle A measures 40 degrees.
We need to find the possible angle measures for B and C if ABC is in isosceles triangle.
For an isosceles triangle, two sides of a triangle are equal. We know that if two sides are equal, the corresponding angles are equal. Let equal angles are x. The sum of an isosceles triangle is equal to 180 degrees. So,
40 + x +x = 180
40 + 2 x = 180
2x = 140
x = 70 degrees
So, the possible angle measures for B and C is equal to 70°.

Answer:
B
Step-by-step explanation:
Givens
a^2 + b^2 = c^2
a = 4x
b = x + 2
c = 3x + 4
Solution
(4x)^2 + (x + 2)^2 = (3x + 4)^3 Remove all the brackets.
16x^2 + x^2 + 4x + 4 = 9x^2 + 24x + 16 Collect like terms on the left
17x^2 + 4x + 4 = 9x^2 + 24x + 16 Subtract the terms on the right
8x^2 - 20x - 12 = 0
This factors into
(4x - 12)(2x + 1)
There are 2 answers
4x - 12 = 0
4x = 12
x = 12/4
x = 3
or
2x + 1 = 0
2x = - 1
x = - 1/2
You have to look at x = -1/2 carefully. The problem is that 4x = 4*(-1/2) = - 2 which is not possible in Euclidean Geometry.
So the only answer is x = 3

If 3x – 9y = 21 and 6x + 3y = 21, which of these could be a value of x or y?
Answer: x=4, y=-1
Step-by-step explanation:
Multiply the second equation by 3:
18x+9y=63
Then summarize both equations 18x+9y+3x-9y=21+63
21x=84 => x=4
use x=4 in any of initial equations ,for instance in first one:
3*4-9*y=21
12-9*y=21
9y=12-21
9y=-9
y=-1
