Answer:
x = -5 and x = -9.
Step-by-step explanation:
To factor this, we need to find two numbers that add to 14 and multiply to 45. These are 5 and 9. Therefore, this equation factors to (x + 5)(x + 9) = 0. The two x values that would make this true are -5 and -9 because they would make (x + 5) and (x + 9) equal to 0 respectively.
60% of a number is 1,944. 61% is 1,976.4. What is 2% of that number?
Answer: 64.8
Step-by-step explanation:
60/100=1944/x (cross multiplication
(1944*100)/60 = 3240
2% of 3240 =
2/100 = x/3240
64.8
( this helps with percentage (%/100=is/of) and cross multiplication)
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.

Answer: 1 ≤ x ≤ 2
Step-by-step explanation:
Given inequality
3 ≤ 6x - 3 ≤ 9
Add 3 on all sides
3 + 3 ≤ 6x - 3 + 3 ≤ 9 + 3
6 ≤ 6x ≤ 12
Divide 6 on all sides

What is the decimal equivalent for a centimeter?
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

Determine the perimeter of the shape to the nearest centimeter. (Picture included)
Answer:
44 cm
Step-by-step explanation:
So we know that the bottom 12 is congruent to to the line at the top, so that is also 12. And the 5 is congruent to the other 3 lines with one hash mark going through it. So perimeter is the sum of all the side lengths on a polygon. So we have 12+12+5+5+5+5=44.

Answer:
p = -49
Step-by-step explanation:
-10 + 7/4p = -38
+7/4 p = -38 + 10. ..........(-10 taken to other side)
+7/4 p = -28
p = -28 × 7/4 ........( now taken 7/4 to other side)

17.6
Answer:
x = 17.6
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

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.

Checkered Cab Taxi charges a $ 5.95 flat rate for a ride in the cab. In addition to that, they charge $ 0.25 per mile. Katie has no more than $ 20 to spend on a ride. At most, how many miles can Katie travel without exceeding her spending limit?
Answer: 56.2 miles
Step-by-step explanation:
5.95+0-25x less or equal 20
0.25x less or equal 20 - 5.95
0.25x less or equal 14.05
X less or equal 14.05/0.25
X = 56.2
Katie can travel at most 56.2 miles in $20.
What is inequality?A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions is called inequality.
According to the given question.
The total money Katie have = $20.
Amount charged by cab taxi for ride = $5.95
Charges for per mile ride = $0.25
Let Katie travel x miles without exceeding her expending limit.
From the given condition we get a inequality
[tex]20\geq 5.95+0.25x[/tex]
Solve the above inequality for x.
⇒[tex]20 - 5.95\geq 0.25x[/tex]
⇒ [tex]14.05\geq 0.25x[/tex]
⇒[tex]x\leq \frac{14.05}{0.25}[/tex]
⇒[tex]x\leq 56.2miles[/tex]
Katie can travel at most 56.2 miles in $20.
