Answer:
Aaron still needs to save $9
Step-by-step explanation:
Assuming the equation is 8a + 56 = 128
8a + 56 = 128
8a = 128 - 56 = 72
8a = 72
a = 72/8 = $9
Answer:
35%
Step-by-step explanation:
Data provided in the question:
P(Master card) = 27% = 0.27
P(American express card) = 19% = 0.19
P( Visa card ) = 22% = 0.22
P( Master and American express card ) = 9% = 0.09
P( Visa and master card ) = 14% = 0.14
P( American express and visa card ) = 6% = 0.06
Now,
The probability of selecting a family that has either a Visa card or an American Express card
= P( Visa card ) + P( American express card ) - P( Visa and American express card )
= 0.22 + 0.19 - 0.06
= 0.35
or
= 0.35 × 100% = 35%
Keep in mind that a coordinate is in the form (x, y), so if you plug those values into the equation y=3x+1, you get 1=3(4)+1, simplified to 1=13, which is an untrue statement. However, I'm assuming you mean that the value of y is 4 and x is 1, which would be written as (1, 4). This would be the solution to this equation because 4=3(1)+1 is 4=4 which is a true statement.
Answer: 
Step-by-step explanation:
Since Gloria cannot pay for each minute talked but for packages of 200 minutes at the rate of $25 each, we have to make calculations according to these conditions as follows:
Month 1:
Gloria talked on her cell phone for 
. So, she had to buy 2 packages of 
for 
each package.
Hence:
Month 2:
Gloria talked on her cell phone for 
. So, she had to buy again 2 packages of for each package.
Hence:
Month 3:
Gloria talked on her cell phone for 
. So, she had to buy 3 packages of for each package.
Hence:
Then, if we take the total Gloria had to pay for the frist three months, we have:
No wonder you have posted this. It is not easy. Scale is a straight line measurement. You need to use a side of a square.
Left: 1 side of a square = 1 meter.
Center: 3 tops of a square = 1 meter.
Therefore 1 side of a square = 1/3 of a meter.
Right: 1 side of a square = 0.5 meters.
