Answer with Step-by-step explanation:
Since we have given that
Angle 12 and angle 11 are complementary.
Mathematically, it is expressed as
------------(1)
measure of angle 10 + measure of angle 11 = 90 degrees.
Mathematically, it is expressed as
----------------(2)
From eq(1), and eq(2), we get that
Hence, angle 12 is congruent to angle 10.
Answer:
x= 2
y = 20
Step-by-step explanation:
y = 6x + 8
y = –4x – 2
y = 4 (6x + 8
)
y = 6 (–4x – 2)
y = 24x + 32
y = –24 -12
___________
y = 20
input that back into the equation to find x
20 = 6x + 8
20 - 8 = 6x
12 = 6x
x= 2
Haracio has 32 stamps. Jenna has 27 stamps. Gary has 16. You can solve this using matrices.
If you are looking for x then it is X = 18
Answer:
40% of the class is Girls, so 12 students are girls
Step-by-step explanation:
add up the ratio
2+3=5
divide by 5
30/5=6
multipy ratio to find totial number of students
2*6=12
2*3=18
divide the number of students to get the pecentage
12/30=0.4=40%
18/30=0.6=60%
