Create a matrix that is equal to F+G. The first matrix below is named F and the second matrix below is named G. Name the new mat

likoan [24]

F+G:

$F+G=\begin{bmatrix}{-1.8} & {-8.6} & {} \\ {2.85} & {-1.4} & {} \\ {-1.8} & {5.1} & {}\end{bmatrix}+\begin{bmatrix}{1.32} & {-1.9} & {} \\ {2.25} & {0.0} & {} \\ {-6.2} & {1.4} & {}\end{bmatrix}$

Then, add the elements that occupy the same position:

$H=\begin{bmatrix}{-1.8+1.32} & {-8.6+(-1.9)} & {} \\ {2.85+2.25} & {-1.4+0.0} & {} \\ {-1.8+(-6.2)} & {5.1+1.4} & {}\end{bmatrix}$

Solve

$H=\begin{bmatrix}{-0.48} & {-10.5} & {} \\ {5.1} & {-1.4} & {} \\ {-8} & {6.5} & {}\end{bmatrix}$

So, we find the element at address h31:

$H=\begin{bmatrix}{h11} & {h12} & {} \\ {h21} & {h22} & {} \\ {h31} & {h32} & {}\end{bmatrix}$

In this case, position h31 is - 8.0

I have $25 all in nickels and dimes. There are twice as many Nickles as dimes. How many of each are there?

Mama L [17]

Answer:

N=250

Step-by-step explanation:

"twice as many nickels as dimes" means N =2D [eq1]

"collection of nickels and dimes is worth $25" means

5N + 10D = 2500 [eq2]

(To avoid using decimal points, PLZ express everything in cents.)

Substitution (substitute N from eq1 into eq2]:

5(2D) + 10D = 2500

10D + 10D = 2500

20D = 2500

D = 125

N=2D [eq1 again]

N=2(125)

N=250

Check:

Is 5(250) + 10(125) = 2500 ?

1250 + 1250 = 2500 ?

2500 = 2500 ?yes
