Answer:
25 and 55
Step-by-step explanation:
Let's call the larger number L and the smaller S
L = 5 + 2×S
And the sum is:
L + S = 80 Subtract S in both sides:
L = 80 - S
Now, substitute this value of L in the first equation:
80 - S = 5 + 2×S Add S in both sides:
80 = 5 + 2×S + S
80 = 5 + 3S Subtract 5 in both sides
75 = 3S Divide both sides by 3
25 = S
We find the value of S, and now we substitute it in the second equation to find the value of L:
L = 80 - 25
L = 55

Luke has a crate with a volume of 2160 cubic inches. The crate is 12 inches long and 18 inches high. Luke wants to put wooden boards into the crate. Each board is the same size as the board shown in the diagram.
Answers
18 blocks would fit in the Crate.
What is Volume?Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
Given:
Volume of Crate= 2160 cubic inch
Now, Volume of each wooden board
= l b h
= 12 x 5 x 2
= 120
so, number of blocks = 2160/ 120
= 18
Hence, 18 blocks would fit in the Crate.

Luke can fit 18 wooden boards, each measuring 12 inches in length, 5 inches in width, and 2 inches in height, into the crate with dimensions 12 inches in length, 10 inches in width, and 18 inches in height.
Given that the crate has a volume of 2160 cubic inches and the dimensions are 12 inches in length, 18 inches in height, and an unspecified width.
Each wooden board has dimensions of 12 inches in length, 5 inches in width, and 2 inches in height, we can calculate how many wooden boards Luke can fit into the crate.
Let's denote the width of the crate as "w".
The volume of the crate is given by the formula: Volume = Length × Width × Height
So, 2160 = 12 × w × 18
Solving for "w":
w = 2160 / (12 × 18)
w = 10
Now that we know the width of the crate is 10 inches, we can calculate how many wooden boards can fit in the crate by comparing their dimensions.
Each wooden board has a volume of 12 × 5 × 2 = 120 cubic inches.
The total number of wooden boards that can fit in the crate:
Number of boards = Crate Volume / Board Volume
Number of boards = 2160 / 120
Number of boards = 18
Therefore, 8 blocks would fit in the Crate.

HELP ASAP PLS

Answer:
inconsistent, none
Step-by-step explanation:
Write both equations in slope-intercept form to see if the lines are parallel.
These two lines have slope m = −2 and different y-intercepts, therefore they are parallel.
Since the lines are parallel, the system is inconsistent and there are no solutions.
The system of equations 4x + 2y = −8 6x + 3y = 9 is inconsistent and has no solutions.
What is system of Equations?A system of equations is a collection of two or more equations with a same set of unknowns.
We need to write both equations in slope-intercept form to see if the lines are parallel.
4x+2y=-8
2y=-8-4x
y=-4-2x,
y=-2x-4, m₁=-2
and 6x+3y=9
3y=9-6x
y=-2x+3, m₂=-2.
So two lines have slope m = −2 and different y-intercepts,
It means two line are parallel.
Since the lines are parallel, the system is inconsistent and there are no solutions.
Hence 4x + 2y = −8 , 6x + 3y = 9 is inconsistent and has no solution.

a. 32

Step-by-step explanation:
Forty percent of the 80 birds were robins.
a. How many of the birds were robins?
b. How many of the birds were not robins?
___________________
Forty percent of the 80 birds that were robins = 40%/100%
To find how many of the birds were robins, use part/whole = part/whole
40%/100% = ?/80
This will tell us how many exact robins were there
To solve, multiply 80 by 40 and then divide all by 100
80 x 40 ÷ 100 = 32
so 32 of the birds were robins
now for b since 32 of the birds were robins out of 80 birds, subtract 32 from 80.
80 - 32 = 48
Use the figure to find the measures of the numbered angle.
Answers
Answer:
angle 1 = 61°
angle 2 = 119°
angle 3 = 61°
angle 4 = 119°
angle 5 = 119°
angle 6 = 61°
angle 7 = 119°
Step-by-step explanation:
angle 1 = 61° (corresponding angles are always equal)
angle 1 + angle 2 = 180° (linear pair)
=> 61° + angle 2 = 180°
=> angle 2 = 180° - 61° = 119°
angle 2 = 119
angle 1 = angle 3 = 61° (vertically opposite angles are equal)
angle 2 = angle 4 = 119° (vertically opposite angle are equal)
angle 4 = angle 5 = 119° (interior opposite angles are equal)
angle 6 = 61° (vertically opposite angles are equal)
angle 5 = angle 7 = 119° (vertically opposite angles are equal)

Answer:
The price was reduced by 25%
Step-by-step explanation:
Not sure how to go step by step on this, because it's kinda obvious once you think about it a bit. You need to find what percent of 40 that 10 equals (if that makes sense). So really it's just what percent of 40 equals 10? and since 10 is one fourth of forty, 1/4, then you convert that to percent: 25% (sorry if this made no sense, i'm not very good at explaining things)

write the equation of the graph in slope intercept form
(3,-3) (-3,-5)
m= -4
Answers
Answer:
y = -4x + 9
Step-by-step explanation:
Slope intercept form is:
y = mx + b
If m = -4
y = -4x + b
Plug the values of the first set of coordinates into this:
y = -4x + b
-3 = -4(3) + b
-3 = -12 + b
Add 12 to both sides of the equation to isolate b:
-3 + 12 = -12 + b + 12
9 = b
So that makes the slope intercept form:
y = -4x + 9

Answers
Answer: Slope of the line formed by the data is -3.
m=-3 for y=mx+b.
Step-by-step explanation: The slope is the change in y (the rise) divided by the change in x (the run) between two points on the line. I'll pick 2 points: (-4,17) and (9,-22). Any two points will work, if it is a straight line. For these points, y, the rise, changes from 17 to -22, for a net change of (-22 - 17) = -39 for y. x, the run, goes from -4 to 9, for a change in x of (9 - (-4)) = 13.
The rise(y) over the run(x) for these points is thus (-39/13) = -3
The slope is -3

Using Substitution solve: y=x+5
4x+y=20
Answers
Answer:
3
Step-by-step explanation:
So first, plugin y to your equation, it should look like this: 4x+x+5+20. Now, we can solve this. Next, we have two x's so we can combine them. The equation will now look like this: 5x+5=20. Now, we have an extra 5 laying around that we need to get rid of, so we can subtract that 5 to both sides of the equation and we get this: 5x-5=20-5 which ends up being 5x=15. Now, we just divide both ides by 5 and since 15 divided by 5 is 3, we get: x=3

The solution of the equation is x = 11/5
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
The given equation is,
3 (4 - 2x) = -x + 1
We have to solve the equation.
Distributive property states that, for three numbers, a, b and c,
a(b + c) = ab + ac
So, 3 (4 - 2x) = (3 × 4) - (3 × 2x)
= 12 - 6x
Substituting,
3 (4 - 2x) = -x + 1
12 - 6x = -x + 1
-6x + x = 1 - 12
-5x = -11
x = 11/5
Hence the solution is x = 11/5.
