5^{x+1}-5^{x+2}=-2500. Find x
Answer:
x is 3
Step-by-step explanation:
[tex] {5}^{(x + 1)} - {5}^{(x + 2)} = - 2500 \\ [/tex]
divide all sides by -1:
[tex] {5}^{(x + 2)} - 5 {}^{(x + 1)} = 2500[/tex]
from law of indices:
[tex]( {5}^{x} . {5}^{2} ) - ( {5}^{x} . {5}^{1} ) = 2500[/tex]
factorise out 5^x:
[tex] {5}^{x} ( {5}^{2} - {5}^{1} ) = 2500 \\ {5}^{x} (20) = 2500 \\ {5}^{x} = 125 \\ {5}^{x} = {5}^{3} \\ x = 3[/tex]
A store sells cheese in half a pound package a recipe calls fpr 1.72 pound of cheese how many packages does the chef need
Answer:

Step-by-step explanation:
Since the store sells by 1/2 packages, we have to round 1.72 UP to 2.00. Then we multiply 1/2pound by 4= 2.00 pounds
after allowing 20percent discount and levying 13percent vat the value of a watch will be rs 904 what is the marked price of watch
9514 1404 393
Answer:
₹1000
Step-by-step explanation:
Let m represent the marked price. After the discount, the price is 0.80m. After the tax is added, the price is (0.80m)(1.13). This value is Rs 904, so the marked price is ...
(0.80m)(1.3) = ₹904
m = ₹904/(0.80×1.13) = ₹904/0.904
m ≈ ₹1000
The marked price of the watch is ₹1000.

The value of expression will be;
⇒ - 34
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ - b + 5y
And, The values are,
⇒ b = 4, y = - 6
Now,
Since, The expression is,
⇒ - b + 5y
Substitute b = 4, y = - 6, we get;
⇒ - 4 + 5 × - 6
⇒ - 4 - 30
⇒ - 34
Thus, The value of expression is,
⇒ - 34

One branch of a stream is 45.27 meters long. It leads into another stream that is 503.62 meters long.
What is the total length of the stream?
From the information given, the total length of the stream will be 548.89 meters
The length of the first stream = 45.27 meters
The length of the second stream = 503.62 meters
The total length of the stream will be equal to the addition of the length of the first stream and the second stream and this will be:
= 45.27 meters + 503.62 meters
= 548.89 meters

Josephine enlarged a picture using a photocopier the original photo was 3.5 inches by 5 inches the copy was 8.5 by 12.5 inches . What is the scale factor of the dilation?
Answer:
the answer is 1 : 2.4 because for every 1 inch on the original image there are 2.4 inches on the modified image.
Step-by-step explanation:
Step 1:
Measure the change in X and Y of a single length of the original image.
X1 = 3.5
Y1 = 5
Step 2:
Measure the change in X and Y of the same length on the modified image.
X2 = 8.5
Y2 = 12.5
Step 3:
use formula SF = X2/X1 = Y2/Y1
(SF = Scale Factor Dilation)
(X2 and Y2 = change in X and Y of the same length on the modified image.)
(X1 and Y1 = change in X and Y of a single length of the original image.)
X2 = 8.5
8.5/X1
X1 = 3.5
8.5/3.5
8.5/3.5 = 2.4
2.4
1 : 2.4

16. An empty jar has a volume of
8x^2 + 2x - 4 cubic inches. Josh pours
4x^2 – 3x +2 cubic inches of water
into the jar. How many more cubic
inches of water could the jar still
hold?
9514 1404 393
Answer:
4x^2 +5x -6
Step-by-step explanation:
The remaining empty space is the difference between the original amount of empty space and the volume that was filled.
(8x^2 +2x -4) -(4x^2 -3x +2) = 8x^2 +2x -4 -4x^2 +3x -2
= (8 -4)x^2 +(2 +3)x +(-4 -2)
= 4x^2 +5x -6
The jar could hold 4x^2 +5x -6 more cubic inches.

Step-by-step explanation:
We know that a quadrilateral will have a total of 360 degrees. We can create an expression and solve for x.
5x + 7x + 3x + 6 + 90 = 360
~Combine like terms
15x + 96 = 360
~Subtract 96 to both sides
15x = 264
~Divide 15 to both sides
x = 17.6
