The Girls:Boys ratio of 7:2 means that there are 7 girls for every boy.
As there are 250 more girls this relates to the 7-2 part of the ratio.
We can then divide 250 by 5 and multiply by 2 to get the number of boys as 100 boys
14.
y = 75, its a vertical angle to 75.
x = 75, its a vertical angle to 75, or alternate interior angle to 75.
15.
y = 74, its a supplementary angle with 106.
x = 106, its a corresponding angle to 106.
16.
y = 90, its a supplementary angle with x.
x = 90, its a corresponding angle with 90.
No he is wrong
3(3-4x) = 9 - 12x or -12x + 9
Answer:
1,458,783,255,601
Step-by-step explanation:
(-1,099)^2
Break it apart:
(-1,099)*(-1,099)
Multiply the signs and numbers:
Two negatives make a positive so you are left with just 1,207,801.
Next, you square 1,207,801:
(1,207,801)*(1,207,801)
And you get the number 1,458,783,255,601
