[tex]2x - 5 = x + 3[/tex]
[tex]2x - x = 3 + 5[/tex]
[tex]x = 8[/tex]
Substitute x = 8 in any equations given. I will use x+3.
[tex]y = x + 3[/tex]
[tex]y = 8 + 3[/tex]
[tex]y = 11[/tex]
Therefore, the answer is (8,11)

An airplane is preparing to Anderson airport it is 39,900 feet above the ground and it is descending at a rate of 3100 hundred feet/min. at the same airport another plane is taking off and will ascend at the rate of 2600 ft./min. when will the two airplanes be at the same altitude and what altitude will it be
Answer:
one plane will be at an altitude of 39900 and the other will be at 33464
Step-by-step explanation:
airplane 1 -
39,900 divided by 3100 = 12.87
airplane 2-
2600 x 12.87 = 33,464

the point (0 0) is a solution to which of these inequalities
Answer:
(0, 0) is the solution of the inequality y - 9 > 3x - 10.
Step-by-step explanation:
Given the solution point
(0, 0)Let us substitute the point (0, 0) in the inequality to determine which inequality satisfies the equation or not.
CHECKING FOR
y - 9 > 3x + 10y - 9 > 3x + 10
substiture (0, 0) i.e. x = 0, y = 0 in the inequality
0 - 9 > 3(0) + 10
-9 > 10
FALSE
CHECKING FOR
y - 9 > 3x - 10y - 9 > 3x - 10
substiture (0, 0) i.e. x = 0, y = 0 in the inequality
0 - 9 > 3(0) - 10
-9 > 10
True
CHECKING FOR
y + 9 > 3x + 10y + 9 > 3x + 10
substiture (0, 0) i.e. x = 0, y = 0 in the inequality
0 + 9 > 3(0) + 10
9 > 10
FALSE
Therefore, we conclude that only the second inequality i.e. y - 9 > 3x - 10 satisfies the inequality.
Hence, (0, 0) is the solution of the inequality y - 9 > 3x - 10.

Answer:
16
Step-by-step explanation:
there are 4 weeks in every month. Therefore, if she trained for 4 months, she trained for 16 weeks. (4*4=16)
Which set of measurements could make a triangle?
1) 1 mm, 2 mm, 3 mm
2) 7 mm, 4 mm, 3 mm
3) 9 mm, 10 mm, 8 mm
4)11 mm 8 mm, 20 mm
help me fast please
Answer:
3.) a. 9mm b. 10mm c. 8mm
Step-by-step explanation:
All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.
Formula:
a + b = (answer) > c

The force of gravity between two objects is given in the relation: g=6.67*(10)^ -11 , k1.k2 d^ 2 Where k1 and k2 are the body masses in kilograms (kg) (d) is the distance between the two objects in meters (m). (g) is the force of gravity. Find the distance between the Earth and the Moon if the mass of the Earth is approximately equal to: 5.98*10^ 24 kg , The mass of the moon is 1.23% of the Earth's mass and the gravitational force between them is approximately 183 * 10 ^ 19 .

-25+x=54 what represents x
Answer:
x=79
Step-by-step explanation:
Y=mx+b
What’s mx+b??
Answer:
Y=-1/2x+1 because b=the y intercept or in other words, the point at which the line crosses the y axis which is at 1. -1/2x because m=the slope and since the line is going down the slope would be negative. Remember rise/run rule, to get to the next point from (0,1) the line goes down 1 and over 2 which would make it 1/2 and since it goes down it is -1/2. The x stays because that is the variable in which you substitute numbers in for to get new points. Thus the y=Mx+b that you are looking for is y=-1/2x+1
Step-by-step explanation:
What is y=mx+b?

Find the slant height of the pyramid.
22.4 in.
16.8 in.
The slant height is
inches.
Answer:
The slant height is 28 inches
Step-by-step explanation:
The slant height of a pyramid
Given a square base pyramid of side 2a and height h, the slant height is calculated as follows:
[tex]s=\sqrt{a^2+h^2}[/tex]
The attached image shows the relationship between the lengths.
There is no specific information about the dimensions provided in the question, but I'm assuming this:
h = 22.4 in
a = 16.8 in
The slant height is:
[tex]s=\sqrt{16.8^2+22.4^2}[/tex]
[tex]s=\sqrt{784}[/tex]
s = 28 in
The slant height is 28 inches
The length of a rectangular garden is 3 yd less than twice its length. The perimeter of the garden is 78 yd. What are the width and length of the garden?
Complete question :
Answer:
Width = 14 yards ; length = 25 yards
Step-by-step explanation:
Given that :
The length of a rectangular garden is 3 yd less than twice its length. The perimeter of the garden is 78 yd. What are the width and length of the garden?
Width of garden (W) = w
Lenght of garden (L) = 2w - 3
Perimeter of a rectangle : 2 (L + W)
2(2w - 3 + w) = 78
2(3w - 3) = 78
6w - 6 = 78
6w = 78 + 6
6w = 84
w = 14 yards
Length = 2(14) - 3
Length = 28 - 3 = 25 yards

What is the first step in evaluating the expression shown below? (12.9 – 3.1) × 6.2 – 2 + 43 A. Multiply 3.1 and 6.2. B. Add 2 and 43. C. Subtract 3.1 from 12.9. D. Subtract 2 from 6.2.
Answer: Subtract 3.1 from 12.9
Step-by-step explanation:
The first step in evaluating the expression (12.9 – 3.1) × 6.2 – 2 + 43 is to open the bracket first and then subtract 3.1 from 12.9 which will give 9.8.
This follows the rule of BODMAS which says that B which stands for Bracket must be opened and solved first in a given expression.

Brent bought 6 packages of Kool-Aid mix priced at for $0.29 each and 2 packages of Sugar priced at $3.92 each and a gallon of water for $0.95. What is the total amount she spent, on the Kool-Aid and Sugar?
Answer:
kool-aid - $1.74
Sugar - $7.84
Total =$9.58
Step-by-step explanation:
kool-aid = $ 0.29 × 6 = 1.74
×6 because she bought 6 packages of Kool-aid and the price of each was $0.29
sugar = $3.92×2 = 7.84
×2 because she bought 2 packages of sugar and price for each was $3.92
total = $9.58
Add $1.74 + $7.84
Error Analysis A classmate found the slope of the line passing through (8,-2) and (8.10), as shown at the right. Describe your classmate's error. Then find the correct slope of the line passing through the given points.
Answer:
m=undefined; 12/0
Step-by-step explanation:
The classmate's mistake is that she should have placed the y and top and the x on the bottom.
m= 10+2/8-8
m= 12/0
The slope is undefined, meaning that it is a vertical line.

Clyde is baking, and the recipe requires 13 cups of flour. Clyde has 2 cups of flour, but he is doubling the recipe to make twice as much. How much more flour does Clyde need? solve the equation
Answer:
8/3 or 2 2/3
Step-by-step explanation:
Each recipe is 1 1/3 >insert unit< of flour but he's baking two recipes. So, you multiply 1 1/3 by 2 to get 8/3, or 2 2/3

Answer:
b = 2c: Ben's age is twice Cindy's. So Cindy is 15 years old
(a + b + c) / 3 = 28: Their average age is 28 This tells us nothing as we already have Anne, Ben and Cindy's ages. It does however give us a quick way to check the answers:
[tex]\frac{a + b + c}{3} = 28\\\frac{39 + 30 + 15}{3} = 28\\\frac{84}{3} = 28[/tex]
Correct, so we know values found are correct.
