Hello
DEF and IKL , equilateral =>
DE = 5x-12 = 3x-4
5x-3x= -4+12
2x= 8
x=4
DE = 5x-12 = 20-12 = 8
KL = 3x+24 = 10x+3
24 -3 = 10x-3x
21 = 7x
x= 21/7 = 3
KJ = 10x+3 = 30+3 = 33
Answer:
7
Step-by-step explanation:
The total number of sides on a dice are 6.
The number of even numbers on a dice are 3 (2,4,6).
Since we have 3 even numbers and include the number 3, we have a total of 4/6. 4/6 simplifies to 2/3.
Your probability of rolling a 3 or even is 2/3.
Answer:
x ≈ - 1.83
Step-by-step explanation:
to solve for x in the question 1.1x + 1.2x - 5.4 = -10
we have
2.3x - 5.4 = -10
collect the like terms
2.3x = -10 + 5.4
2.3x = -4.2
divide both sides by the coefficient of x
2.3x/2.3 = -4.2/2.3
x = -1.826
x ≈ - 1.83
Answer:
y= 5
x= 2x+5=11 --- 2x=11-5--- 2x/6
x=3
