Answer: Luis started by adding 4.8b to both sides

Step-by-step explanation:

4.8 is a positive number so therefore it should be subtracted from both sides to make the right side be empty in that position.

Brainly do ur magic pls.?
jok3333 [9.3K]

1. 3y

multiplying 3 and y together gets 3y

2. y-5

5 less implies that we subtract 5 from y

3. y+7

adding 7 to y, self-explanatory

4. 9y

same thing as #1

5. \frac{y}{8}

quotient of implies division, since number y is listed first, y is the numerator

The vertex angle of an isosceles triangle measures ( 6x -9)° and one of the base angles measures (4x)°. What is the value of x?
Gnom [1K]

Answer:

x = 13.5

Step-by-step explanation:

We know that base angles of an isosceles triangle are equal. The base angles of the triangle are (4x)° each. The vertex angle of the traingle is (6x-9)°. So according to angle sum property of triangle,

6x - 9 + 4x + 4x = 180

=  > 6x - 9 + 8x = 180

=  > 14x - 9 = 180

=  > 14x = 180  + 9 = 189

=  > x =  \frac{189}{14}  = 13.5

Please answer this! Im desperate UvU,
Ratling [72]
Part A:

x=5
4x-1 ≤19
4(5)-1 ≤19
20-1 ≤19
19 ≤19

x=5
4x-1<19
4(5)-1<19
19<19

Explanation:
In problem one the greater then symbol has a line under it, this means that the symbol now means greater then or equal to. Since 19 is equal to 19 it is correct. In problem to the greater then symbol has no line under it meaning it only means greater then. Since 19 is not greater then 19 it is false.
So basically the difference is:
≤ = greater then or equal to
< = greater then


Part B:
5x+2=47
-2 -2
5x=45
/5 /5
x=9

Explanation:
Since when you solve the equation x=9 the value 9 from the set makes the equation.


Hope this helped :)
