Answer:
(2,3)
Step-by-step Explanation:
2x - y = 1
-y = -2x + 1
y = 2x - 1
4x + y = 11
4x + 2x -1 = 11
6x = 12
x=2
y=2x-1
y=2(2)-1
y=3
Answer:2
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Every small block represents a hundredth.
0.54
5 tenths , 4 hundredth
There are 3 of these,
So,
15 tenths and 12 hundredth
12 hundredths = 1 tenth and 2 hundredths
Making it 16tenths and 2 hundredths
= 1.62
(16 tenths = 1 whole and 6 tenths)
It will be 80/2 and 0/10 you will have to multiply 10*80/2=4000
Step-by-step explanation:
m∠RSU + m∠UST = 90° (as complementary angles)
(7x + 3)° + (11x − 21)° =90°
18x -18° = 90°
18x = 108°
x = 6
so, m∠RSU = (7x + 3)° = 7(6)+3 = 45°
and m∠UST = (11x − 21)° = 11(6) -21 = 45°
