Answer:
Step-by-step explanation:
angle 1 and angle 2 add to 180 degree because they are supplementary angel and in supplementary angle sum of two angles is 180 degree
angle 1 and angle 3 is equal as they are vetically opposite angles and vertically opposite angles are always equal.
angle 3 and 4 add to 180 degree because they are supplementary angle and in supplementary angle sum of two angles id 180 degree.
angle 2 and angle 4 are equal because they are vertically opposite angles and vertically opposite angles are always equal.
Step-by-step explanation:
Let x = Rosalyn's hourly wage and we know that she earns this much up to 40 hrs per week. Beyond 40 hrs, her hourly wage increases to 2.5× the original rate so since she worked 8hrs past 40 hrs, we can write her total salary for the week as
Solving for x, we find that
or
Answer:
Part a)
Part b) 132:89 vs 132 to 89
Part c)
Part d) 66:7 vs 66 to 7
Step-by-step explanation:
Let
x ----> the number of boys
y ----> the number girls
z ----> the number of adults
we have
x=132, y=89, z=14
Part a) Write the ratio of the number of boys to the number of girls.
To find the ratio of the number of boys to the number of girls, divide the number of boys by the number of girls
so
substitute
Part b) Write the same ratio using another form (A: B vs. A to B)
we have
The other form is
132:89 vs 132 to 89
Part c) Write the ratio of the number of boys to the number of adults
To find the ratio of the number of boys to the number of adults, divide the number of boys by the number of adults
so
substitute
Simplify
Part d) Write the same ratio using another form
The other form is
66:7 vs 66 to 7
Answer:
B, C, D
Step-by-step explanation:
the distance from (0,0) to (3,2) would be (3,2). Flip that and you get (2,3).
the distance from (1,5) to (4,7) is (3,2). Also flip that and you get (2,3)
the distance from (-2,-2) from (4,2) is (6,4). flip that and you get (4,6). break it down and you'll get (2,3)
Answer:
6
Step-by-step explanation:
5y + 2 +2y + 3 = 12 - 15
7y + 5 = 12y - 15
7y + 20 = 12y
20 = 5
