Answer:
x = -8
Step-by-step explanation:
1) 5x + 7= 7x +23
Move the terms
2) 5x + 7 -7x = 23
Collect like terms
3) 5x -7x = 23 - 7
Calculate
4) -2x = 16
Divide both sides by -2
5) x = -8

Helppp me with this math problem
Answer:
x=10 yards
Step-by-step explanation:
66=(x+12)(x-7)
66=x²-7x+12x-84
66=x²+5x-84
0=x²+5x-84-66
0=x²+5x-150
0=(x+15)(x-10)
x+15 = 0 or x-10=0
x=-15 or x=10
It can't be -15 as both sides would have negative lengths which is impossible so it has to be 10.
x+12 = 10+12 =22
x-7 = 10-7 = 3
22*3 = 66

Please Help!!! I will mark the brainiest and 70 points!
Answer:
darkest shaded- 0.8 times 0.7= 0.56
In the middle- 0.8 times 0.3= 0.24 times 0.2 times 0.7= 0.14 0.24 + 0.14= 0.38
Light- 0.2 times 0.3= 0.06
0.38 + 0.06=0.44
0.56 times 0.44= 0.2464

Johnny wants to know how many students in his school enjoy watching science programs on TV. He poses this question to all 26 students in his science class and finds that 75% of his classmates enjoy watching science programs on TV. He claims that 75% of the school's student population would be expected to enjoy watching science programs on TV. Is Johnny making a valid inference about this population? (5 points)
a
Yes, it is a valid inference because his classmates make up a random sample of the students in the school
b
Yes, it is a valid inference because he asked all 26 students in his science class
c
No, it is not a valid inference because he asked all 26 students in his science class instead of taking a sample from his math class
d
No, it is not a valid inference because his classmates do not make up a random sample of the students in the school
Answer: d. No, it is not a valid inference because his classmates do not make up a random sample of the students in the school
