Answer:

The total amount he saved this month=84×3=$252

Step-by-step explanation:

Last month he saved 21 dollars each week for 4 weeks, to calculate the total amount he saved for the for weeks, we can express this as;

Total amount=Amount he saved per week×Number of weeks  

Where;

Amount he saved per week =$21

Number of weeks=4 weeks,

Replacing;

Total amount=21×4=$84

This month he saved 3 times as much money as he saved last month, this can be expressed as;

The total amount he saved this month=Amount saved last month×3

Where; Amount saved last month=$84

Replacing;

The total amount he saved this month=84×3=$252

x+2y+2z=3. 2x-2y-z=3. x-2z=-5​
d1i1m1o1n [39]

Answer:

x = 1, y = -2, z = 3.

Step-by-step explanation:

x + 2y + 2z = 3      A

2x -2y - z = 3         B

x - 2z = -5              C

If we add equations A and B we eliminate y:

3x + z = 6       E

Multiply E by 2 :

6x + 2z = 12    F

Adding C and F we get:

7x = 7

x = 1.

Plug this into equaton C:

1 - 2z = -5

-2z =  -5 - 1 = -6

z = 3.

Now plugging x = 1 and z = 3 in equation A:

1 + 2y + 2(3) = 3

2y = 3 - 1 - 6 = -4

y = -2.

Question 29 of 40<br> Find f(-2) for f(x) = 5.3*.
blsea [12.9K]

Answer:

A. \frac{5}{9}

Step-by-step explanation:

To find f(-2) in f(x)=5*3^x, plug in -2 into all the x values.

f(-2)=5*3^-2, you can use calculator to calculate 3^-2 which equals 0.1, forever 1's.

f(-2)=5*0.1=0.5  Forever 5's.

f(-2)=0.5 or \frac{5}{9}

Hope this helps!

If not, I am sorry.
