Let the three odd integers be x - 2, x and x + 2
x - 2 + x = 3(x + 2) + 7
2x - 2 = 3x + 6 + 7
2x - 2 = 3x + 13
3x - 2x = -2 - 13
x = -15
The three consecutive odd integers are -17, -15 and -13.
Answer:
The 4th one;
y = -5
Step-by-step explanation:
The line is horizontal, therefore it just needs to be the same as the y-value, which is -5. Here is an image for you to explain it.
Answer:
A biker takes 10 hours to drive 60 miles.
Step-by-step explanation:
"<span>Artie needs to save $450 to buy the new bicycle that he wants. He currently has $300. What percent of the cost of a new bicycle has he saved?"
Write and solve an equation of ratios (proportions)"
$300 x
--------- = ------- which results in x = 300/450 = 0.667 (approx.) or 20/3.
$450 1
and this works out to 67% (answer)</span>
Step-by-step explanation:
similar triangles means that if the angles are the same in both triangles, then the lengths of the corresponding sides relate to each other via the same multiplication factor.
in our example here, both triangles are similar, because they have the same angles.
the side of 6m length corresponds to the side of 72m length. that is a multiplication factor of 72/6 = 12.
now, also the other 2 sides would use the exactly same factor.
therefore, the height of the building is 2×12 = 24m.
