E. 5x+3 = 28
5x = 28 - 3
Divide by 5
Final answer = 5

F. 3x-9 = 18
3x = 18 + 9
18 + 9 = 27
Divide by 3
Final answer: 9

G. 8x-1=7
8x = 7 + 1
7 + 1 = 8
8x = 8
Divide by 8
Final answer: 1

H. 3x+5 = 10
3x = 10 - 5
10 - 5 = 5
Divide by 3
Final answer: 5/3

i. 13 + 7x = -1
7x = -1 - 13
-1 - 13 = -14
Divide by 7
Final answer: -2

j. 14 = 3x + 5
-3x + 14 = 5
-3x = 5 - 14
-3x = -9
Divide by - 3
Final answer: 3

K. 4x - 7 = -13
4x = -13 + 7
4x = -6
Divide by 4
Final answer: -3/2

l. -3 = 2x+ 9
-2x - 3 = 9
-2x = 9 + 3
9 + 3 = 12
2x = 12
Divide it by -2
Final answer: -6

What is the height of cone S?
balu736 [363]

Answer:

12 cm

Step-by-step explanation:

First, we find the scale factor from cone S to cone T.

ratio of volumes = (vol of T)/(vol of S) = (6144 pi cm^3)/(768 pi cm^3) = 8

The ratio of the volumes is 8:1

The scale factor, which is the ratio of linear dimensions (height, radius, etc.), is the cubic root of the ratio of the volumes.

scale factor = cubic root of 8 = 2

The height of cube T is 24 cm, so the height of cube S is 24 cm/2 = 12 cm.

X/-9 =3<br>I dont understand this.​
STatiana [176]

Final Answer: x = -27

Steps/Equations:

Question: \frac{x}{-9} = 3

Step 1: Move the negative sign to the left side.

-\frac{x}{9} = 3

Step 2: Multiply both sides by 3.

-x = 3 * 9

Step 3: Simplify 3 * 9 to 27.

-x = 27

Step 4: Multiply both sides by -1.

x = -27

Using y=mx+b find the slope for<br> 7) 8x + 3y = −9
malfutka [58]

Answer:

-8/3

Step-by-step explanation:

8x + 3y = - 9

Let's make y the subject of the formula.

y = - 9/3 - 8x/3

Rearrange

y = - 8x/3 - 3

The slope is the coefficient of x which is - 8/3

Sweets are sold loose, or pre-packed in 120g bags. The 120g bags are ?1.49 each. The loose sweets are ?0.89 for 100g. By calcula
tester [92]

Answer:

The loose sweets at ?0.89 for 100 g.


Step-by-step explanation:

First, calculate the price per gram. You do this by dividing the price by the grams.

?1.49 / 120 g =  1.49 / 120 = 0.0124 (4 dp)

Because the answer was very long, I have rounded it to 4 decimal places (4 dp).

?0.89 / 100 g = 0.89 / 100 = 0.0089

Next, you must calculate both pre-packed and loose sweets to the same weight. I am calculating them both to 100 g.

0.0124 x 100 = 1.24

0.0089 x 100 = 0.89

Finally, the cheapest product for 100 g will be the better value. In this case, it is the loose sweets.
