1) Find 3/4 of 24:
24/4=6
6*3=18
2) Find 1/9 of 18 (which is three forth of 24):
18/9=2
2*1=2
One ninth of three fourth of 24 is equal to 2.

The table can be used to determine the solution of equations, 2x − 2y = 6 and 4x + 4y = 28.

natta225 [31]

we have

$2x-2y=6$ ------> equation $1$

$4x+4y=28$ ------> equation $2$

Multiply by $2$ the equation $1$

$4x-4y=12$ ------> equation $3$

Sum equation $2$ and equation $3$

$4x+4y=28\\ 4x-4y=12\\ ------\\ 8x=40\\ x=40/8\\ x=5$

Substitute the value of x in the equation $2$

$4x+4y=28$

$4*5+4y=28\\ 4y=28-20\\ 4y=8\\ y=8/4\\y=2$

therefore

the answer is the option B

$(5,2)$

What is the difference of (5 + 3i) and (2 + 9i)?

ehidna [41]

Answer:

3+12i

Step-by-step explanation:

The difference of 5+3i and 2 + 1999 can be calculated as follows

= 5+3i - 2+9i

Collect the like terms

= 5-2+3i+9i

= 3+12i

Hence the difference of 5+3i and 2+9i is 3+12i

Hhh I’m very bad at math

barxatty [35]

Answer:

See below;

Step-by-step explanation:

21 . Consider an exponential function;

$Exponential Function in Form - y = a * b^x, where, a - start value, b - growth factor, x - time,\\\\Now y = f ( x ), in Other Words,\\p ( t ) = 300 * ( 0.5 )^t - Given,\\\\Through Substitution - f ( x ) = p ( t ), a = 300, b = 0.5, x = t,\\\\Conclusion ; 300 - ( start value ) - Starting Amount of Milligrams of Compound,\\0.5 - Milligrams Compound Decreases by$
