Write 12 ten thousands, 8 thousands,14 hundreds, 7 ones in standard form
Cloud [144]
<span><u><em>The correct answer is: </em></u>
129,407.

<u><em>Explanation</em></u><span><u><em>: </em></u>
12 ten-thousands = 12*10000=120,000.
8 thousands = 8*1000=8000;
<u>this gives us</u> 120,000+8,000=128,000.

14 hundreds = 14*100=1400;
<u>this gives us</u> 128,000+1,400=129,400.

7 ones = 7*1=7;
<u>this gives us</u> 129,400+7=129,407.</span></span>

What the solution 2(4+2x)≥5x+5
olga nikolaevna [1]

Answer:

x ≤ 3

Step-by-step explanation:

2(4+2x) ≥ 5x+5      (by PEDMAS, expand parentheses first)

4(2) + 2x(2) ≥ 5x + 5

8 + 4x ≥ 5x + 5   (subtract 8 from each side)

4x ≥ 5x + 5  - 8

4x ≥ 5x - 3    (subtract 5x from both sides)

4x -5x ≥ - 3

-x  ≥ - 3  (multiply both sides by -1, remember to flip the inequality when multiplying both sides by a negative number)

x ≤ 3

Find the value of x please help I give brainly<br> 20 points
fiasKO [112]

Answer:

x=148

Step-by-step explanation:

First, find the missing angle by subtracting 100+48 from 180 (all of the angles in a triangle add up to 180). Then, subtract that from 180 (the angles are a linear pair, so they are supplementry, so they add up to 180) x+32=180.

x=148.
