Answer:
17 - 7m
Step-by-step explanation:
Assuming you require to subtract the expressions, then
16 + m - (8m - 1) ← distribute parenthesis by - 1
= 16 + m - 8m + 1 ← collect like terms
= 17 - 7m
Answer:
drag 10 to the
Step-by-step explanation:
Answer:
y = 3
x = 2
Step-by-step explanation:
-5x + 4y = 2
9x - 4y = 6
Sum both eq.
-5x + 9x = 4x
+4y - 4y = 0
2 + 6 = 8
then:
4x + 0 = 8
4x = 8
x = 8/4
x = 2
from the first eq.
-5x + 4y = 2
-5*2 + 4y = 2
-10 + 4y = 2
4y = 2 + 10
4y = 12
y = 12/4
y = 3
Check:
from the second eq.
9x - 4y = 6
9*2 - 4*3 = 6
18 - 12 = 6
Complementary angles are those angles whose sum is 90 degree.
The measurement of two complementary angles are
There sum have to be 90 degree. That is
Combining like terms ,
Moving 20 to right side
Dividing both sides by 5
So the measurement of the angles are

B
