Step-by-step explanation:
What
Answer:
75.95cm
Step-by-step explanation:
<u>4.9 multiplied by 15 will represent the 15</u> <u>seconds</u>
4.9 • 15 = 73.5
<u>4.9 divided by 2 will equal the 1/2 seconds</u>
4.9 ÷ 2 = 2.45
<u>add them all together</u>
73.5 + 2.45 = 75.95 cm
You know that the two angles make up a perfectly flat line, which is a 180<span>° angle. So we can create the equation:'
3x + 10 = 12x
Now solve for 'x'. Subtract 3x to both sides:
10 = 9x
Divide 9 to both sides:
x = 10/9
We want to find the smaller angle, so put this value in for 'x' in '3x + 10':
3x + 10
3(10/9) + 10
30/9 + 10
13 1/3</span><span>°</span>
Answer:
17 in,3 in, and 19in
so the third answer
Step-by-step explanation:
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
