The answer is (6, 7)
This is the system of two equations:
<span>2y − x = 8
y − 2x = −5
_____
Express the second equation in the term of y:
2y - x = 8
y = 2x - 5
_____
Substitute y in the first equation:
2(2x - 5) - x = 8
4x - 10 - x = 8
4x - x = 10 + 8
3x = 18
x = 18/3
x = 6
Since x = 6 and y = 2x - 5, then:
y = 2 * 6 - 5
y = 12 - 5
y = 7
Therefore, (x, y) = (6, 7)</span>
Answer:
4
Step-by-step explanation:
use your fingers and count 2 fingers then put 2 more up and count how many u got then. boom u got 4
Let's first turn 1 9/10 into an improper fraction, which is 19/10
so if R/12 equa;s 19/10, cross multiply
10r equals 228
divide both sides by 10, you get r= 22.8
Answer:
2
Step-by-step explanation:
If this product was written as an equation, it would look like this:
16 - 7 * 2
PEMDAS states that multiplication comes before addition. So, the first step in the equation is to multiply 7 and 2.
7 * 2 = 14
Now, the equation looks like:
16 - 14
All we need to do now is subtract 14 from 16.
16 - 14 = 2
So, the final answer is 2.
60 counters =1
2/3 of 60
60/3 =20
20x2=40
