Answer:
- Let the first number = x
- Therefore, the other number = x + 2 (x+2 is so as in two consecutive even numbers there is 1 odd number)
- Now, According to question
- x + x + 2 = 122
- 2x + 2 = 122
- 2x = 122-2
- 2x = 120
- x = 120/2
- x = 60
- Now, first no. = x = 60
- Therefore, second no. = x + 2 = 60 + 2 = 62
- Equation 60 + 62 = 122

Answer:
2,742.50
Step-by-step explanation:
2194 x 1.25 = 2742.50
You subtract 2x from both sides so you would get -3y=8-2x. finally you divide by -3 o both sides so your answer is y=8-2x/-3
Answer:
x ≈ 4
Step-by-step explanation:
We use tan∅ to solve this:
tan30° = x/7
7(tan30°) = x
x = 4.04145
Remember that tangent is opposite over adjacent.
Answer:
<u>The answer is 1. 64 and 2. 60</u>
Step-by-step explanation:
Question 7. 75% of what number is 48?
Number = x
75%x = 48
3x/4 = 48 (75% = 3/4)
3x = 192 (Multiplying by 4 at both sides of the equation)
<u>x = 64</u> (Dividing by 3 at both sides of the equation)
<u>Part 75 Whole 48 Part 100 Whole 64</u>
Question 8. 120% of what number is 72?
Number = x
120%x = 72
12x/10 = 72 (120% = 12/10)
12x = 720 (Multiplying by 10 at both sides of the equation)
<u>x = 60</u> (Dividing by 12 at both sides of the equation)
<u>Part 120 Whole 72 Part 100 Whole 60</u>
