Answer:
Step-by-step explanation:
3x - 4y = 13 (1)
2x + y = 5 (2)
——————
3x - 4y = 13
4(2x + y = 5) (2) times 4
——————-
3x - 4y = 13
8x + 4y = 20
——————-
11x = 33
x = 33/11
x = 3
Plug x = 3 in (2):
2(3) + y = 5
6 + y = 5
y = 5-6
y = -1
Thus, x = 3 and y = -1
Answer:
48
Step-by-step explanation:
A = bh/2
A= 8 x 12 / 2
A= 96 / 2
A = 48
Aimme is right. All the sides are obtuse. They do not equal exactly 90 degrees.
Answer:
The second one or B- "He did not find the prime factors of 4."
Step-by-step explanation:
I got it right on Edge2020
We know that 5 fits entirely into our number three times, and then there's a remainder of 4.
If 5 fits three times exactly, it means that our number is at least 15 (5x3).
From here, we have a remainder of 4, which leads to 15+4=19
