2 times x -4=12
2x-4=12
Let x= 8
(2.8)-4=12
16-4= 12
So the answer is 8
The amounts for each donut are given as follows:
<h3>How to obtain the amounts?</h3>
The amounts for each donut are found applying the proportion, multiplying the decimal equivalent of each percentage by the total number of donuts.
From the problem, the total number of donuts is given as follows:
100 donuts.
The percentages of each type of donuts are given as follows:
The decimal equivalent of each percentage is given as follows:
Hence the amounts are given as follows:
- Strawberry: 15, as 0.15 x 100 = 15.
- Chocolate: 45, as 0.45 x 100 = 45.
- Sprinkle: 40, as 0.4 x 100 = 40.

The total surface area of the remaining solid is 48(4+✓3) centimeters square.
<h3>How to calculate the surface area?</h3>
Through a regular hexagonal prism whose base edge is 8 cm and the height is 12 cm, a hole in the shape of a right prism.
The formula for the total surface area will be:
= Total surface area=2(area of the base)+ parameter of base × height
where,
Height= 8cm
Parameter of base=12(2) = 24
Area of the base= 6×✓3/4×4² = 64✓3/4
The surface area of the remaining solid will be:
= 2(64✓3/4) + 24 × 8
= 2(64✓3/4 + 192
With the hole is a rhombus prism with the following parameters:
diagonal 1 = 6, diagonal 2 = 8, height = 12
The volume is:
V1 =0.5 × d1 × d2 × h
V1 = 0.5 × 6 × 8 × 12
V1 = 96
The dimensions of the hexagonal prism are:
Base edge (a) = 8
Height (h) = 12
The volume is
V2 = (3✓(3)/2)a²h
V2 = (3✓3)/2) × 8² × 12
V2 = 1152✓3
The remaining volume is
V = V2 -V1
V = 1152✓3 - 96

Answer:
x = -8
Step-by-step explanation:
Since there is no slope, there is no need for a y variable to appear in your final equation. The graph will cross y = -8 horizontally. So therefore, x = -8
This is a pretty short explanation, but there's not too much to it. Hope this helped :)
