Answer:
x=5
Step-by-step explanation:
4x-6=x+9
add 6 to both sides
4x=x+15
subtract 1x from both sides
3x=15
divide by 3 on both sides
x=5
The answer is D. 1,000,000
A calculator would answer this, but i’m assuming your asked to make a estimate without a calculator. An easier way to look at dividing by fractions would be multiplying by its reciprocal
Since this fraction is .004 or 4/1000 the reciprocal would be 1000/4, or 250.
Since 250 times 4,367 is still a relatively hard multiplication problem. I would just make the 250, 200.
Now that the problem is simplified, a trick when multiplying any number divisible by 10, is to take the zeros out, multiply the number, then add them back.
So 4,367 x 2 = about 8,600, then adding two 0s from the 200, that is now 860,000.
Looking at the answers the closest to this is 1,000 so the answer is D

/ ___ \ Let's imagine a trapezoid looks like this. The two parallel lines would be the top and the bottom lines.
The 10 in. side would be either the top or bottom line. The other parallel line is twice as long, meaning it's 2 times longer. So you multiply 10 in x 2 = 20 in.
The given side length = 10 inches.
Height = half as long, meaning it's half of 10 in. = 5 in.
Formula of a trapezoid =
x height
Where a and b are bases. The top and bottom of the trapezoid are bases.
Area trapezoid =
x 5 =
x 5 = 15 x 5 = 75 in² <-- area means the unit is squared
