Answer:
what exactly did u want me to work out?
Step-by-step explanation:
To do this, divide the numerator by the denominator. The result is the decimal form of the ratio. For example, convert 7:2 to a decimal value.
The answer for the completion exercise shown in the image attached above is:
1) Multilplication property of equality (If you multiply mEFG+mGDE=360° both sides of the equation by 1/2, you obtain 1/2(mEFG)+1/2(mGDE)=180°).
2) m∠D=1/2(mEFG)
3) m∠F=1/2(mGDE)
4) By the substitution property of equality (Because if you substitute m∠D=1/2(mEFG) and m∠F=1/2(mGDE) into 1/2(mEFG)+1/2(mGDE)=180°, you obtain: m∠D+m∠F=280°).
-4x + 6y = 24
4x + y = -10
7y = 14
y = 2
2x - 6 = -12
2x = -6
x= -3
The answer is:
Solve for y in the first equation
y=−5<span>
y=8−<span>x
</span></span>
<span>Replace all occurrences of y with the solution found by solving the last equation for y. In this case, the value substituted is <span>−5</span></span><span>y=−5</span><span><span>(−5)</span>=8−<span>x
</span></span>
Remove parentheses.<span>y=−5</span><span>−5=8−<span>x
</span></span>
Solve for x in the second equation.<span>y=−5</span>
<span>x=13</span>
The answer is <span>(13,−5<span>) Please mark as Brainliest
