This may help you, remember one thing while multiplying by power of 10, the no. of digits under the bar should be EQUAL to the ten's power.
I believe the answer should be C
Answer:
Step-by-step explanation:
- Use ratios to solve for x. Corresponding sides have same ratio.
Q1
- (x + 5)/30 = (36 - 20)/20
- (x + 5)/30 = 16/20 = 4/5
- 5(x + 5) = 4(30)
- 5x + 25 = 120
- 5x = 95
- x = 19
Q2
- (5x - 2)/(3x + 1) = 39/26
- (5x - 2)/(3x + 1) = 3/2
- 2(5x - 2) = 3(3x + 1)
- 10x - 4 = 9x + 3
- 10x - 9x = 3 + 4
- x = 7
TS = 3x + 1 = 3(7) + 1 = 22
Answer:
3.95
Step-by-step explanation:
R = 7.9/2 = 3.95
Answer:
1/x+5
Step-by-step explanation:
1. Rewrite 3x as a difference
x-2/x^2 + 5x-2 - 10
2. Factor out x from the equation, then factor out -2.
x-2/ x+(x+5) - 2(x+5)
3. Factor out x+5 from the expression
x-2/ (x+5)(x-2)
4. Reduce the fraction with x-2
x-2 / (x+5) x-2
1/x+5
