Answer:
$5
Step-by-step explanation:
Let the variables A, B, C, D represent a sack of apples, a bunch of bananas, a cantaloupe, and a carton of dates, respectively. Then the problem statement gives rise to 3 equations:
A +B +C +D = 20
D = 2A
C = A -B
Substituting the last two equations into the first gives ...
A +B + (A -B) +2A = 20
4A = 20 . . . simplify
A = 5 . . . . . divide by 4
Substituting this into the last equation, we have ...
C = 5 -B
B + C = 5 . . . . add B
The cost to purchase a bunch of bananas and a cantaloupe is $5.
We would subtact 3 from both sides allowing the equation to simplify to -8c=32
We would then divide both sides by -8 to equal -4
The final answer C=-4
We are asked to simplify the ratio of 34 laptops out of 116 computers into the simplest form. The greatest common factor is 2. hence, we divide each number by 2. 34 divided by 2 is equal to 17 while 116 divided by to is equal to 58. Hence the answer to this problem is b. 17 <span>laptops : 58 computers. </span>
Answer:
=57.89%
Step-by-step explanation:
The total number of golf ball is 4+8+7 = 19
P (red or yellow) = number of red or yellow
------------------------------------
total number of golf balls
= 4+7
-----
19
=11/19
Changing this to a percent means changing it to a decimal and multiplying by 100%
= .578947368 * 100%
=57.8947368%
Rounding to two decimal places
=57.89%
