The answer is A
You can solve this by equation the two equations, by substitution method or elimination. Let's choose the substitution since Equation 2 has already X isolated
-take the X in equation 2 and substitute in the first equation
So, You should have 5 (5-3/2 y) -4y =7
Get y ( I'll assume you know how to simplify and find y by yourself )
y=36/23
-Now take y and substitute it in the first equation or the second equation (it doesn't really matter)
Substituting y in Equation 2:
x=5- 3/2 (36/23)
=> x= 61/23
So answer is A where (x,y) is (61/23, 36/23)
Answer:
E. Step 3
Step-by-step explanation:
Step 2:
2x + 18 = 4x + <u>28 + 2</u>
Step 3:
2x + 18 = 4x + <u>26</u>

Answer:
15.3
Step-by-step explanation:
tan(42) =a/17
a=tan(42)*17
575 times 0.08 equals 46.(chicken)
575 times 0.20 equals 115.(salad)
575 times 0.16 equals 92.(burgers)
575 times 0.24 equals 138.(fruit)
