When it says 4x4 and 12x2 does that mean it’s squared or multiplied by those?
Answer:
.125
Step-by-step explanation: To convert 1/8 to a decimal, divide the denominator into the numerator. 1 divided by 8 = . 125. To convert the decimal .
Number of weekend minutes used: x
Number of weekday minutes used: y
This month Nick was billed for 643 minutes:
(1) x+y=643
The charge for these minutes was $35.44
Telephone company charges $0.04 per minute for weekend calls (x)
and $0.08 per minute for calls made on weekdays (y)
(2) 0.04x+0.08y=35.44
We have a system of 2 equations and 2 unkowns:
(1) x+y=643
(2) 0.04x+0.08y=35.44
Using the method of substitution
Isolating x from the first equation:
(1) x+y-y=643-y
(3) x=643-y
Replacing x by 643-y in the second equation
(2) 0.04x+0.08y=35.44
0.04(643-y)+0.08y=35.44
25.72-0.04y+0.08y=35.44
0.04y+25.72=35.44
Solving for y:
0.04y+25.72-25.72=35.44-25.72
0.04y=9.72
Dividing both sides of the equation by 0.04:
0.04y/0.04=9.72/0.04
y=243
Replacing y by 243 in the equation (3)
(3) x=643-y
x=643-243
x=400
Answers:
The number of weekends minutes used was 400
The number of weekdays minutes used was 243
Answer:
48
Step-by-step explanation:
Using Uclid's division algorithm, the HCF of 960 and 432 can be obtained as follows:
Here, 960 is greater and 432 is smaller. We divide 960 by 432.
STEP 1:
960 = 432*2 + 96
STEP 2:
Divide divisor (432) by remainder (96)
432 = 96 * 4 + 48
STEP 3:
Divide divisor (96) by remainder (48)
96 = 48 * 2 + 0
Since, remainder at this step is zero (0), so the HCF would be the divisor of this step which is 48.
Thus, HCF of 960 and 432 is 48
