Cross multiply:
X * 5 = 4 * 2

Simplifying
X * 5 = 4 * 2

Reorder the terms for easier multiplication:
5X = 4 * 2

Multiply 4 * 2
5X = 8

Solving
5X = 8

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Divide each side by '5'.
X = 1.6

Simplifying
X = 1.6

Nick will move a storage bin from its current location to the new location shown on the coordinate plane. Describe how Nick coul

Answer:

Move downward by 7 units

Move leftward by 6 units

$(x,y) \to (x -6,y-7)$

Step-by-step explanation:

Given

See attachment for grid

Required

The transformation from the current location to the new location

To do this, we pick two corresponding points on the current location and the new location.

We have:

$A = (3,2)$ -- Current location

$A' = (-6,-5)$ -- New location

First, move A downwards by 7 units.

The rule to this is:

$(x,y) \to (x,y-7)$

So, we have:

$(3,2) \to (3,2-7)$

$(3,2) \to (3,-5)$

Next, move the above points leftward by 6 units.

The rule to this is:

$(x,y) \to (x-6,y)$

So, we have:

$(3,-5) \to (3-6,-5)$

$(3,-5) \to (-3,-5)$

Simplify the expression.

Maksim231197 [3]

Answer:

6.8x - 5

Step-by-step explanation:

To answer this question I combined like terms:

(2.5x + 4.3x) - 5

2.5x + 4.3x = 6.8x

Then you add the 5 to the end of the expression:

6.8x - 5

Pyramid A is a square pyramid with a base side length of 14 inches and a height of 6 inches. Pyramid B has a volume of 3,136 cub

leonid [27]

The Volume of PYRAMID A is 8 times greater than the Volume of PYRAMID B as obtained by taking the ratio of the volume of both pyramids.

Volume of a square based pyramid is given as :

$V = a^2h/3$

Where; h = height ; a = base edge

Hence, Volume of PYRAMID A :

$V = 14^2 * (6/3)\\\\V = 392 in^3$

Volume of PYRAMID B = 3,136 in³

Divide Volume of pyramid B by pyramid A :

$3136 in^3 / 392 in^3$

= 8 times

Expressing as a percentage, multiply by 100% ;

8 * 100% = 800%

Therefore, The volume of PYRAMID B is 800% times GREATER THAN that of PYRAMID A.

Something on sale for $725. The original price was $1299. To the nearest tenth of a percent, what was the rate of discount?

ElenaW [278]

Answer:

44.2%

Step-by-step explanation:

Rate of discount = (difference in prices / original price) x 100

Difference in price = $1299 - $725 = $574

Original price = $1299

($574 / $1299) x 100 = 44.187837%

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

the hundredth figure is 8, which is greater than 5. 1 would be added to the tenth figure.

So it becomes 44.2%
