X = a number
x = 3

x + 4 ? = 7 , 7 - 4 = 3

x = 3 , 4 + 3 = 7

x = 3

i hope this helps

X+4=7
So subtract 4 from both sides which means to put minus four under the four and seven.For example x+4=7
-4 -4
Then cross out the two fours.
Afterwards do 7-4
Which gives you 3
So 3 is your number.

Solve for x 7(3-x) = 8(4-2x)

Damm [24]

Answer:

x = 11/9

Step-by-step explanation:

Eliminate parentheses, add 16x, subtract 21.

7(3 -x) = 8(4 -2x) . . . . given

21 -7x = 32 -16x . . . . . eliminate parentheses using the distributive property

9x +21 = 32 . . . . . . . . add 16x

9x = 11 . . . . . . . . . . . . subtract 21

x = 11/9 . . . . . . . . . . . .divide by the coefficient of x

Find the range of possible values for the following measurements, which were rounded to the nearest mm, tenth of m, and hundredt

zmey [24]

The required range of the data is 24mm

The range of data is the difference between the largest value and the least value in a set of data.

Since we are not given the range of data. Let's assume we gave the following data:

34mm, 30mm, 20mm, 44mm, 31mm

From the data

Highest measurement = 44mm

Least measurement = 20mm

Find the range

Range = Highest measurement - Least measurement

Range = 44mm - 20mm

Range = 24mm

Hence the required range of data is 24mm

<em>NB: The concept can be applied to any set of data given for other measurements in (b) and (c)</em>

The rocket's height when the distance between you and the rocket is 100 feet is 98.9 feet

<h3>How to determine the rock's height?</h3>

The function is given as:

d = √216 +h²

At a distance of 100 feet, it means that:

d = 100

So, we have:

√216 +h² = 100

Take the square of both sides

216 +h² = 10000

Subtract 216 from both sides

h²= 9784

Take the square root of both sides

h = 98.9

Hence, the rocket's height when the distance between you and the rocket is 100 feet is 98.9 feet
