Answer:
x = -9
Step-by-step explanation:
-15x - 40 = 23 - 8x
Add 8x to both sides
-15x + 8x - 40 = 23
-7x - 40 = 23
Add 40 to both sides
- 7x = 23 + 40
-7x = 63
Divide both sides by (-7)
x = 63/-7
x = -9
Answer:
1. 601/1000
2. 60.1/100
3. 6.01/100
Step-by-step explanation: To get 60.1% to a fraction, divide by 100. You will get 60.1/100, which is the answer with the denominator of 100. For the denominator of 1000, multiply the numerator and denominator by 10.
60.1 x 10 = 601
100 x 10 = 1000
The fraction for the denominator with 1000 is 601/1000. For the denominator of 10, divide the numerator and denominator by 10.
60.1/10 = 6.01
100/10 = 10
The fraction for the denominator with 10 is 6.01/10.
Answer:
h = 6 cm
Step-by-step explanation:
Volume of cylinder = 54 π cm³
πr²h = 54π
π * 3 * 3 * h = 54π
Let's do subtraction by first starting with the ones place and then the tenths place of the subtrahend.
45-4=41; 44, 43, 42, 41
41-.5= 40.5; 40.9, 40.8, 40.7, 40.6, 40.5
45-4.5=40.5
We can check by using addition.
40.5+4.5=
44+1=
45
Answer:
sec A = 5/4
Step-by-step explanation:
Sec of an angle is hypotenuse/adjacent side
In your problem, sec A = 25/20 = 5/4
