Answer:
I will answer when i get back
Step-by-step explanation:
The expression would be 19x-9. The reason is because if you think about it, it says that there is 9 less than 19x (x would be the unknown number) I hope this helps! ^-^
B = 4
a=2
b=4
c=2
it’s just solving simultaneous equations
Answer:
x = 2.
y = 6.
Step-by-step explanation:
Consider the triangle on the left.
Because there are 2 equal angles at the vertex on the bottom right:
3/9 = x/(8 - x)
1/3 = x / (8 - x)
3x = 8 - x
4x = 8
x = 2 (answer).
Similarly, for the second triangle:
3/y = 2/4
3/y = 1/2
y = 6
(answer).
Answer:
0.365 m to the nearest thousandth.
Step-by-step explanation:
7/9 * 13.4
= (7*13.4)/9
= 10. 4222 m
4/7 * 17.6
= (4*17.6)/7
= 10.0571
10.422 - 10.057
= 0.3651
