Answer:
12
Step-by-step explanation:
Ok, first write it as an equation, 3x-12=24. Next, you need to simplify, add 12 to each side, getting 3x=36. Lastly, subtract 3 from each side which gives you x=12
I would go with an <span>irrational number because the 0.86421 is a real number and it can't be expressed as a fraction or ratio </span>
Answer:
10.57 cm²
Step-by-step explanation:
Recall that the area of a triangle is gotten by (1/2)*base*height
If the height of the triangle is 5.45cm and the base is 3.88cm, then the area can be calculated by multiplying the two numbers and dividing it by 2.
5.45*3.88 = 21.146cm²
This still needs to be cut in half (otherwise we are yielding the area of a rectangle with these dimensions)
21.146 cm²/2 = 10.573 cm²
This can be rounded to the nearest hundredth
= 10.57 cm²
keeping in mind that standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
