Answer:\
y=10
Step-by-step explanation:
5 times 6 to 30
30=20+y
Subtract 20 from both sides.
30-20=y
Simplify 30-2o to 10.
10=y
y=10
Answer
7. 30
8. 54
Step-by-step explanation:
For 7 do 2x+3x=90 because it is a right angle
then solve for x and get 15
to get the angle you are looking for multiply 2 by 15
and get the answer 30
For 8 to find the value of x you would need to...
add (4x+6) + (11x-6)= 180 because 180 is a straight angle.
Then simply solve for x and get 15x=180 which equals 12
The to get the angle you plug it in to (4x+6) and get the answer 54
Statement 1 is an example of conditional probability.
Events with conditional probability always follow the format:
The probability of A happening, given that B has already happened.
Answer:
We need to flip the symbol at the end of the question.
answer: x<= 6.5
Step-by-step explanation:
Given inequality: 2(x-4)+5<=4(x-4)
Distribute: 2x-8+5<=4x-16
Undo a constant term from left side: 2x-3<= 4x-16
Combining the like terms: 2x-4x<=-16+3
Undo the coefficient term from left: -2x<=-13
Undo the variable term: x<=(13/2)=6.5
Now checking if this is write: Lets take x=6<6.5
Put x=6 in given inequality:
2(6-4)+5<=4(6-4)
2(2)+5<=4(2)
4+5<=8
9<=8 (which is not possible)
so we need to flip the inequality
2(x-4)+5>=4(x-4)
9>8
