Step-by-step explanation:
3x+5=4
move the positive number to the right side over the equal sign.
NB.lf the number that u moved over is positive(it as a plus sign before it ) the number will become negative when moved over the equal sign. If the number has a minus sign then when it is moved over the equal sign it becomes positive.
so for this because we have a +5.it will then be
3x=4-5
3x=-1
To get x you divide both side by 3
3x/3=-1/3
therefore x =-1/3
K12 i just took the test and the answer is very simple the convert it to a decimal but in simplest form and the answer is 0

Answer: 1300 cm^3, 850 cm^2
Step-by-step explanation:
With a triangular prism, you need to calculate the surface area of the triangle first and then the length. Here's how to solve for the volume (A):
Triangles is b*h/2, plug in the equation
10*13/2
130/2
65
Now use the length of the rest of the shape, which is 20 cm.
65*20=1300
the volume is 1300 cm^3.
for B, finding the surface area requires you to analyze each individual part of the shape.
Each part colored in represents a different shape:
Red:
10*20=200
Blue:
13*10/2=65
65*2=130 (Two triangles)
Green:
13*20=260
260*2=520 (Two rectangles)
Add them all up together.
200+130+520= 850 cm^2
Answer:
18 muffins
Step-by-step explanation:
Amount of flour Maggie used
Total amount of flour she bought - Amount of flour left over.
= 45oz - 14.72 oz
= 30.28 oz of flour
She used 17.5 oz to make a loaf of bread, and 0.71 oz for each muffin.
Hence,
Let the number of muffins = x
17.5 + 0.71x = 30.28
0.71x = 30.28 - 17.5
0.71x = 12.78
x = 12.78/0.71
x = 18 muffins
Therefore, Maggie made 18 muffins
