It would be 4. Multiply each side by -1/5.

It would cancel out the -1/5 leaving -15 = x.

X2+5x=3x+11 and solve by completing the square

Butoxors [25]

$x^2+5x=3x+11\\
x^2+2x-11=0\\
x^2+2x+1-12=0\\
(x+1)^2=12\\
x+1=\sqrt{12} \vee x+1=-\sqrt{12}\\
x=-1+2\sqrt3 \vee x=-1-2\sqrt3$

1.4t−0.4(t−3.1)=5.8<br><br> SOLVE FOR Y

VladimirAG [237]

There is no y in this question, however we can solve for t.

1.4t - 0.4(t - 3.1) = 5.8
1.4t - 0.4t + 1.24 = 5.8
t + 1.24 = 5.8
t = 4.56

Answer all 4 please

FrozenT [24]

1)
$180 - (37 + 90) = 180 - 127 \\ = 53$
2)
$(180 - 15) \div 2 = 165 \div 2 \\ = 82.5$
each of other angles measures 82.5 degrees

3)
$180 - (42 + 20) = 180 - 62 \\ = 118$
4)sorry I don't know the last one
