Answer:
C. 70 = 10x
E. 15x = 105
Step-by-step explanation:
x = 7
Using method of elimination;
A. X + 7 = 17
Substituting the value of x;
7 + 7 ≠ 17 (Incorrect option)
B. 7 = 17 - x
Substituting the value of x;
7 ≠ 17 - 7 (Incorrect option)
C. 70 = 10x
Substituting the value of x;
70 = 10 * 7 (Correct option)
D. X/35 = 5
Substituting the value of x;
7 / 35 ≠ 5 (Incorrect option)
E. 15x = 105
Substituting the value of x;
15 * 7 = 105 (Correct option)
Answer: 14/45
Step-by-step explanation: The probability that they first event will occur is 2/10. The probability that the second event will occur is 1/9. If you multiply those like it says in the hint you will get 14/45. (I think this is right)
Answer:
9 ft
Step-by-step explanation:
Let x represent the shortest piece. Then the sum of lengths is ...
x + (x +25) +3x = 40
5x = 15
x = 3
3x = 9
The third piece is 9 feet long.
_____
<em>Check</em>
The pieces are 3 ft, 28 ft, 9 ft, so total 40 ft, as required.
14% of 40,000,000 is 5,600,000
Answer:
the sum of four consecutive whole number is 150
a. let x represent the first number. write expression to represent the other three numbers.
1st: x
2nd: x+1
3rd: x+2
4th: x+3
write and solve an equation to find the four numbers
Add those expressions to get:
4x+6 = 150
4x = 144
x = 38
x+1 = 39
x+2 = 40
x+3 = 41
