Answer:

\huge\boxed{4.5,\ \text{See explanation for steps.}}

Step-by-step explanation:

If we have the equation 16=2(4d-8)-4, our goal is to isolate the variable d on one side of the equation.

We can do this by performing a series of steps to reverse the equation.

1. Apply the distributive property on the right side:

16=(4d \cdot 2) + (2 \cdot -8) - 4\\\\16 = 8d - 16 - 4

2. Combine like terms on the right side:

16 = 8d + (-16-4)\\\\16 = 8d-20

3. Add 20 to both sides:

16 + 20 = 8d -20 + 20\\\\36 = 8d

Divide both sides by 8:

36 \div 8 = 8d \div 8 \\\\ 4.5 = d

So d=4.5.

Hope this helped!

Find the side length of X
7nadin3 [17]

Answer:

7√3

Step-by-step explanation:

We can use pythagoreans theorem to solve this

Since, we know one side, and the hypotenuse, we can solve for the other side.  

Pythagoreans theorem: a²+b²=c²

Where a and b are two sides, and c is the hypotenuse (the side opposite of the right angle)

In this triangle, 7 is the side, and 14 is the hypotenuse.

I will plug in the values into pythagoreans theorem, and then simplify:

a^{2}+b^{2} =c^{2} \\\\7^{2} +x^{2} =14^{2} \\\\49+x^{2} =196\\\\x^{2} =147\\\\x=\sqrt{147} \\\\x=\sqrt{49*3 }\\\\ x=\sqrt{7^{2} *3 }\\\\x=7\sqrt{3}

So x = 7√3

Answer:

A) Each of the smaller donations is $20.

B) The larger donation is greater than the smaller donations by $15.

Step-by-step explanation:

4+4+7 is equal to 15, and divide 75 by 15 to get $5 per part. Multiply 4 by 5 to get $20 for a smaller donation, and 7 by 5 to get $35 for the larger donation. Hope this helped :)
