Answer:
my answer was 7.5
Step-by-step explanation:
2
2b+3b-10
4b+3b-10
10-7b=3b fraction bar means divide so...
3b
__ 2
4b because... b-2b=4b and 8-4b=4b
3/4 =7.5 because 4 cant go into three so you add a decimal and a zero and move decimal up and 4 can go into 30 7 time which equals 28 and 30-28 is 2 add another zero and its 20 and 4 goes in 5 times which equals 20 and 20-20=0 so its 7.5 (i hope this helps ;)
1/3(a + b) = 60
a + b = 60 * 3 = 180
1/4(a - b) = 28
a - b = 28 * 4 = 112
a + b = 180
a - b = 112
---------------add
2a = 292
a = 292/2
a = 146
a + b = 180
146 + b = 180
b = 180 - 146
b = 34
so ur 2 angles are : 146 and 34
Paul must get 13 since Peter gets more more than Jane so Jane would get 7 and then peter would get 12
Answer:The flag of a country contains an isosceles triangle (recall that an isosceles triangle contains two angles with the same measure) if the measure of the third angle of the triangle is 20 degrees more than twice the measure of either of the other two angles and find the measure of each angle of the triangle (Recall that the sum of the measures of the angles of a triangle is 180 degrees)
Step-by-step explanation:
The perimeter of any polygon is equal to the sum of the length of all sides of this polygon.
Therefore:
<h3>P = 29 + 15 + 4xy = 44 + 4xy</h3>
