Equation 1) 10x + 2y = 30
Equation 2) 4x + y = 4
Multiply all of equation 2 by 2.
2) 2(4x + y = 4)
2) 8x + 2y = 8
1) 10x + 2y = 30
Subtract equations from each other.
-2x = -22
Divide both sides by -2.
x = -22/-2
x = 11
B) x = 11

Step-by-step explanation:
Answer:
C. x = 8 is a solution, but x = 6 is not
Step-by-step explanation:
12 + 6 = 18
12 + 8 = 20
20 - 12 = 8
Answer:
<h2>X = 59°</h2>
Step-by-step explanation:
To find Angle X we use sine
sin∅ = opposite/ hypotenuse
From the question
WY is the opposite
WX is the hypotenuse
So we have
sin X = WY/ WX
sin X = 6/7
X = sin-¹ 6/7
X = 58.99
X = 59° to the nearest tenth

Answer:
0.5 or 1/2
Step-by-step explanation:
Step 1. 40/50−15/50
Step 2. 40-25= 25/50
Step 3. 25/50÷ 5 =5/10
5/10÷ 5 =1/2
4/5−3/10=1/2
