Answer:
x = 6
y = 4
Step-by-step explanation:
Let the two numbers be x and y
<u><em>Condition 1:</em></u>
7x+3y = 54 -----------(1)
<u><em>Condition 2:</em></u>
x = 2+y -----------------(2)
<em>Putting (2) in (1)</em>
=> 7(y+2)+3y = 54
=> 7y+14+3y = 54
=> 10y = 54-14
=> 10y = 40
<em>Dividing both sides by 10</em>
=> y = 4
<em>Now putting y = 4 in eq(2)</em>
=> x = 2+4
=> x = 6
Answer:5
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
you need to first do 5.89- [(5.89 * 15)/100]=5.89-0.8835=5.0065
then 5.0065 * 2 = 10.013 because it is 15% each dozen then
[(10.013 * 5)/100] =0.50065 then 10.013 - 0.50065 = 9.51235
and lastly (9.51235 * 7)/100 = 0.6658645
finally 9.51235 + 0.6658645= 10.1782145
and then you just need to round it to the nearest hundredths and you will get 10.18
Answer:
1560
Step-by-step explanation:
First (2 1/2)/(1/4) = (5/2)(4) = 20/2 = 10
Next, 3/(1/4) = 3(4) = 12
Lastly, (3 1/4)/(1/4) = (13/4) x 4 = 52/4 = 13
This means we need 10 rows of 12, 13 high. 10(12)(13) = 1560 cubes.
Another way is to multiply 2 1/2 x 3 x 3 1/4 = 5/2 x 3 x 13/4 = 195/8
A 1/4 inch cube is 1/4 x 1/4 x 1/4 for a volume of 1/64
(195/8)/(1/64) = (195/8)(64) = 1560 cubes.
Both have the same when simplified to its lowest point in the expression
