25+8x=5+12x whats the answer?
Answer:
x = 5 (see below)
Step-by-step explanation:
Combine like terms by subtracting on both sides:
25 + 8x = 5 + 12x
20 = 4x
Then divide:
20 = 4x
5 = x
Move the variable to the left side of the equation:
x = 5

The students in the After-School Club ate 12 grapes per minute. After 9 minutes, there were 32 grapes remaining. The table shows the number of carrots remaining after different amounts of time. Which snack did the students eat at a faster rate? Explain.
Answer:
Grapes
Step-by-step explanation:
The rate of change for the grapes was -12 grapes per minute.
To calculate the rate of change for the carrots, use the slope formula [tex]m = \frac{y_{1}-y_{2} }{x_{1}-x_{2} }[/tex]. In this case, m is the rate of change, time is x, and the carrots remaining is y.
[tex]m = \frac{118-136}{8-6} = \frac{-18}{2} = -9[/tex]
The decrease in grapes was much greater than the decrease in carrots, so therfore the students ate the grapes at a faster rate.
If the table shows the number of carrots remaining after different amounts of time. The students eat grapes at a faster rate.
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables.
It is given that, the students in the After-School Club ate 12 grapes per minute. After 9 minutes, there were 32 grapes remaining.
Grapes were changing at a pace of -12 grapes per minute. Use the slope formula to get the rate of change for the carrots.
m=118-136/8-6
m=-18/2
m=-9
The students consumed the grapes more quickly because the decline in grapes was significantly larger than the decline in carrots.
Thus, the table shows the number of carrots remaining after different amounts of time. The students eat grapes at a faster rate.

The average distance from the Sun to Mars is 22,793, 910,000,000 centimeters.
The conversion factors between centimeters and four other units of measure are shown below.
9.46. 10^17 cm = 1 light-year
1.50.10^13 cm = 1 astronomical
1 . 10^5 cm = 1 kilometer
1. 10^2 = 1 meter
For the distance to be expressed as x units of measure, where 1 < x < 10, which unit of measure must be used?
A Light-years
B) Astronomical units
C)Kilometers
D) Meters

Step-by-step explanation:
sarah used 2.5 cups of cheese in a dish that serves 10 people amyn used 1.6 cups of cheese in a dish that serves 8 people how much more cheese is in one serving of sarahs dish
Answer:
[tex]\frac{1}{20}[/tex] more cheese in Sarah's dish than Amyn.
Step-by-step explanation:
To find this, we need to get the two fractions, [tex]\frac{2.5}{10}[/tex] and [tex]\frac{1.6}{8}[/tex] to a common denominator. The closest one is a multiple of 4 for [tex]\frac{2.5}{10}[/tex] and a multiple of 5 for [tex]\frac{1.6}{8}[/tex] .
This makes both fractions much more comparable, and we have
[tex]\frac{10}{40}[/tex] for Sarah's dish
[tex]\frac{8}{40}[/tex] for Amyn's dish.
Knowing Sarah has [tex]\frac{2}{40}[/tex]'s more cheese in her dish, we can still simplify, so after dividing 40 by 2, we get [tex]\frac{1}{20}[/tex], the simplest form of how much more cheese Sarah has in her dish than Amyn,

Find the distance, c, between (–4, –3) and (2, 1) on the coordinate plane. Round to the nearest tenth if necessary.
Answer:
d=√((x_2-x_1)²+(y_2-y_1)²)
d=√((2-(-4))²+(1-(-3))²)
d=√(6²+4²)
d=√36+16
d=√52
d=7.21110255...
d=7.2
Step-by-step explanation:
d=7.2
The distance between the points on the coordinate plane is 7.2 units.
What is coordinate geometry?Coordinate geometry is the study of geometry using the coordinate points. It provides a link between geometry and algebra through line graphs and curves.
For the given situation,
The points are (x1, y1) be (–4, –3) and (x2, y2) be (2, 1)
The formula for the distance between points,
[tex]d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }[/tex]
On substituting the above points,
⇒ [tex]d=\sqrt{(2-(-4))^{2}+(1-(-3))^{2} }[/tex]
⇒ [tex]d=\sqrt{6^{2}+4^{2} }[/tex]
⇒ [tex]d=\sqrt{52}[/tex]
⇒ [tex]d=7.211[/tex] ≈ [tex]7.2[/tex]
Hence we can conclude that the distance between the points on the coordinate plane is 7.2 units.

Mr. Gardner is making 6 treat bags. He has 185 chocolate-covered raisins to share evenly among the treat bags.
How many chocolate-covered raisins will be in each treat bag?
How many chocolate-covered raisins will be left over?
Answer:
30 chocolate covered rasins
5 left over
Step-by-step explanation:
Step 1: 185 Divided by 6 and that gets you 30, and some left over.
Step 2: Do 6 x 30 and that gets 180
Step 3: Do 185 subtract 180 and then you get 5
Step 4: So 30 chocolate coverd raisins will go in each bag, and 5 will be left over.

2) r = 16/2 = 8 cm
Area of top and bottom = 2*πr²
= 2 * 3.14 * 8 * 8
= 401.92 cm²
Midlle part = h * πd
= 6 * 3.14 * 16
= 301.44 cm²
Total = 401.92 + 301.44
= 703.36 cm²
3) Area of front and back = [tex]2* \frac{1}{2}*b * h\\[/tex]
[tex]= 2*\frac{1}{2} * 3 * 4\\\\= 12 cm^{2}[/tex]
Area of bottom = length * breadth
= 12* 3
= 36 cm²
Area of left = 12 * 4
= 48 cm²
Area of right = 12 * 5 = 60 cm²
Total = 12 + 36 + 48 + 60 = 156cm²
