Answer:

_ = 48

Step-by-step explanation:

7 (3 + 5) = 8 + _

7 x 3 + 7 x 5 = 8 + _

21 + 35 = 8 + _

56 = 8 + _

_ = 56 - 8

_ = 48

Hope that helps!

Answer: x = 48

PEMDAS

7 (3 + 5) = 8 + x

7 (8) = 8 + x

56 = 8 + x

isolate x by subtracting 8

48 = x

Y=x+5<br> 4x+y=20<br> Solving system by substitution

sineoko [7]

Y = x + 5....so we sub in x + 5 for y in the other equation

4x + y = 20
4x + x + 5 = 20
5x + 5 = 20
5x = 20 - 5
5x = 15
x = 15/5
x = 3

y = x + 5
y = 3 + 5
y = 8

solution is (3,8)

28.8 drops will occur in one day because if you multiply 1.2 by 24, it will equal 24. I multiplied by 24 because 1 day is 24 hours

PLEASE HELP

Take the longer leg length as $x$

$(x-8)^2+x^2=(x+8)^2 \\ \\ x^2-16x+64+x^2=x^2+16x+64 \\ \\ x^2-32x=0$

Use the formular
$x={ \frac{-b+ \sqrt{ b^2-4ac}}{2a} } \\ \\ x={ \frac{32+32}{2} } \\ \\ x=32$

∴ shorter leg = 32 - 8 = 24ft
longer leg = 32ft
hypotenuse = 32 + 8 = 40ft
