Step-by-step explanation:
h~mmmmm maybe im wrong
X in the equation 2/X+1/2=3/4 equals 8
We can find this by first finding the common denominator of 1/2 and 3/4 which is 2/4.
Then we can ask, 2/4+?=3/4
By asking this question we can find out that 2/4+1/4=3/4
With this new knowledge we can now ask 2/?=1/4. Which will lead us to the answer 8.
Answer: her call lasted for 44 minutes
Step-by-step explanation:
Linda purchase a prepaid phone card for $30. This means that the credit on her card is $30.
Long distance calls cost $0.17 each. Linda use her card only to make a long distance call. Assuming she made a total of x minutes of long distance calls, the cost would be $0.17x. The amount remaining on her card will be
30 - 0.17x
if the remaining credit on her card is $22.52, the number of minutes,x that the call lasted will be
22.52 = 30 - 0.17x
0.17x = 30 - 22.52
0.17x = 7.48
x = 7.48/0.17 = 44
Answer:
mZD=62
Step-by-step explanation:
mZC=-x+26
mZD=2x-10
mZC≅mZD
-x+26=2x-10
Add x to both sides: 26=x-10
Add 10 to both sides: 36=x
Substitute x for 36 in the mZD equation: mZD=2(36)-10
Solve!
