Answer: help with what? whats the question?
Step-by-step explanation:
1 peso = 0.053 dollars.
x pesos = 400 US dollars.
1/x = 0.053 / 400 Cross multiply
400 * 1 = 0.053 x Divide by 0.053
400/0.053 = 0.053*x / 0.053
7547.17 pesos which rounded is
Answer: 7547 pesos
Answer:
x = -8
Step-by-step explanation:
3x - 9= -33
+9=-33+9
<u>3x = -24</u>
3 3
x = -8
The solution is (-4,4)
Step-by-step explanation:
Given equations are:

In linear combination method, we have to make coefficients of any one variable opposites by multiplying with an integer
So multiplying 2nd equation by -2

Adding Equation 1 and Equation 3:

Dividing both sides by 3

Putting y=-4 in equation 1

Dividing both sides by 4

Hence,
The solution is (-4,4)
