Answer:
9 boys and 12 girls
Step-by-step explanation:
if you multiply the denominators by 3, you get "out of" 21. All you need to do after that is multiply the top by 3 as well and it tells you there are 9 boys and 12 girls.
The value of 7 in 7,283 is 10 times the value of 7 in 2,783
Answer:
last one
Step-by-step explanation:
x = width
x+6 = length
Area = length times width
x(x + 6) = 
+ 6x
+ 6<em>x = 114 (subtract 114 from both sides) </em>
<em /><em> + 6x -114 = 0</em>
Answer:
7168
Step-by-step explanation:
Answer:
105
Step-by-step explanation:
Theorem:
If parallel lines are cut by a transversal, then same-side interior angles are supplementary.
Lines AB and CD are parallel, and angles 3 and 6 are same-side interior angles, so by the theorem above, angles 3 and 6 are supplementary. That means that the sum of their measures is 180 deg.
m<3 + m<6 = 180
m<3 + 75 = 180
Subtract 75 from both sides.
m<3 = 105
Answer: 105 degrees
