Answer:

-26

Step-by-step explanation:

x=7

3 is being multiplied by X

replace X with 7 in your equation

Your equation should then look like this: 3(7)-47

The parentheses around the 7 indicate that the 7 is being multiplied by the 3 or in other words: (3*7)-47

multiply 3 and seven before subtracting 47

3*7= 21

Once you have your answer to that subtract 47, your answer should be a negative # because you are subtracting a larger # from a smaller #

21-47= -26

so if X equals 7. 3x-47= -26

Find the distance from the point (4,2) to the point (0,1).

vagabundo [1.1K]

Answer:

4.123 units

Step-by-step explanation:

Data provided:

Coordinates of point 1 as ( 4 , 2)

and,

Coordinates of point 2 as ( 0 , 1 )

Now,

The distance between the two point whose coordinates are given is calculated using the formula as:

distance = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

on substituting the values, we get

distance = $\sqrt{(0-4)^2+(1-2)^2}$

distance = $\sqrt{(-4)^2+(-1)^2}$

distance = $\sqrt{16+1}$

Distance = √17 = 4.123 units

Alik [6]

Answer:

F = 110°

I'm not sure, but since no one answered, here it goes...

Step-by-step explanation:

∵ FD = FE (Given in Diagram)

∴ ΔDFE is isosceles , ∴m∠E = m∠D

1 ) 3x + 14 = 5x

14 = 5x - 3x

14 = 2x

14 / 2 = x

7 = x

m∠E = 3*7 + 14 = 35°

m∠D = 5*7 = 35°

m∠F = 180 - (35+35)

m∠F = 110°

Please help thank you very much.

Hello!

First you have to find the volume of the cube

To do this we use the equation a^3

a is a side length

24^3 = 13824

The maximum pyramid can have a maximum side length of 24 and a maximum height of 24 since that is what the cube measurements are

The equation for the volume of a square pyramid is

$a^{2} \frac{h}{3}$

a is side length
h is height

put in 24 for the values

$24^{2} \frac{24}{3}$

Square the 24

$576 \frac{24}{3}$

Divide

576 * 8 = 4608

The answer is B) 4608 cubic centimeters

Hope this helps!

Amit and Tiana simplified the expression -4 [8 + (-6) +3] in different ways Amit`s first step was to add the three numbers withi

zepelin [54]

Part A: (8 × (-4)) (-6 × (-4)) (3 × (-4))

Part B: -6 × -4 = 24. So when multiplying -6 by -4, the product should be 24

But basically, Tiana's way of solving this question is correct while Amit's is incorrect.And this is because Amit is using PEMDAS, unlike Tiana.
