2 consecutive integers such that 7 times the smaller is less than 6 times the greater. What are the greatest such intergers
Answer:
The numbers are
22 and 23 to solve a problem like this, we need to read and define as we go. Let me explain. So we know that there are two consecutive integers. They can be
x and x+1
. Since their consecutive, one has to be 1
number higher (or lower) than the other. Ok, so first we need "seven times the larger"( 7x+1)
Next, we need to "minus three times the smaller" 7(x+1)−3x
Is equal to " 957(x+1)−3x=95
Alright! There's the equation, now we just need to solve for x! First we are going to get everything on one side and distribute the 7=7x+7−3x−95=4x−88
Pull out a
=4(x−22)Now that we have two terms, we can set them both equal to
0 and solve.4≠0
This can never be true, lets move to the next term (x−22)=0x=
22 That's it! So your two consecutive numbers are
22
The greatest such intergers are; Lesser = x = 6. Greater = x + 1 = 7
How to find the sum of consecutive integers?To find the sum of consecutive integers, we will use
[tex]1 + 2 + 3 + ... + n = \dfrac{n(n+1)}{2}[/tex]
Here, Two consecutive integers represented as variables:
x, x + 1
Greater one: x + 1
Lesser one: x
Write as an equation
6(Greater) = 7(Lesser)
Substitute in known value;
6(x + 1) = 7(x)
Multiply
6x + 6 = 7x
Subtract 6x from both sides of the equation
6 = x
Lesser = x = 6
Greater = x + 1 = 6 + 1 = 7

Find the perimeter of the trapezoid. Leave your answer in simples radical form
Answer:
Perimeter = 105 + 15√3 in
Step-by-step explanation:
✔️Find the height of the trapezoid using trigonometric ratio:
Reference angle = 60°
opposite = height
Adj = 45 - 30 = 15 in
Thus:
Tan 60 = opp/adj
Tan 60 = height/15
height = 15*tan 60
height = 15√3 (tan 60 = √3)
✔️Find the slant height (hypotenuse) using Pythagorean Theorem:
Hypotenuse = √(height² + adj²)
Hypotenuse = √((15√3)² + 15²)
= √(675 + 225)
Hyp = √900
Hyp = 30
✔️Perimeter = 30 + 45 + 30 + 15√3
Perimeter = 105 + 15√3 in
How do you find the diameter of a circle. Or what is the diameter of 56.52
Answer:
Assuming that the Radius is 56.52, the diameter would be 113.04
Step-by-step explanation:
The equation for finding diameter of a circle is r2 (I think) but it means Radius times 2, as radius if half of the diameter.
A system of equations is shown on the graph below.
On a coordinate plane, 2 lines intersect at (negative 1, 2).
How many solutions does this system have?
no solutions
one unique solution
two solutions
an infinite number of solutions
Answer: One unique solution.
Step-by-step explanation:
When we have a system of linear equations like:
y = a*x + b
y = c*x + d
We have 3 possibilities:
1) There is only one solution, this happens when in the graph, the lines intersect at only one point.
2) There is no solution, in this case, the lines never intersect, this would be the case of two parallel lines.
3) We have an infinite number of solutions, this happens when both lines intersect in an infinite number of points, and this can only happen when both lines are the same line.
In this case, we know that we have two lines and they intersect in only one point, (-1, 2)
Then we have only one solution, and the solution is (-1, 2)

Answer:
(a) Yes, AA postulate (b) SSS theorem long side: 35; total perimeter: 80Step-by-step explanation:
1. Both triangles are right triangles, and the vertical angles at C are the same measure. Hence, the triangles are similar because they have two congruent angles: the AA postulate applies.
__
2. The shortest-to-longest side ratios are ...
3 : 6 : 7
18 : 36 : 42 = 6(3) : 6(6) : 6(7) = 3 : 6 : 7
Corresponding sides are proportional, so the SSS theorem applies.
__
3. Larger triangle side lengths are a factor of 5 times those of the smaller triangle. The missing side of the larger triangle is 5×7 = 35. The total perimeter of the larger triangle is 20+25+35 = 80. The required length of fence depends on what is being fenced (not specified).

The value of the expression 42−6×4(12)³ is, -41430
What is the PEMDAS rule?PEMDAS is an acronym that stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). It is a mathematical order of operations that helps to simplify expressions and solve mathematical problems in a consistent manner. The PEMDAS rules dictate the order in which operations should be performed in an expression to ensure that the correct answer is obtained.
Given that,
The expression,
⇒ 42−6×4(12)³
⇒ 42 - 24(12)³
Now, we will open a bracket
And for that will write value of (12)³
⇒ 42 - (24×12×12×12)
⇒ 42 - 41472
⇒ - 41430
Hence, the result is - 41430

3) When Jackie took her children to the movie theater, she bought one box of candy and three small drinks for
$14.75. When Alex went to the same theater and bought two boxes of candy and five small drinks, he paid
$26.
a) Set up a system of equations to model this situation. Be sure to define the variables that you use.
b) Determine, algebraically, the cost for one box of candy and one small drink
Answer:
c + 3d = 14.75
2c + 5d = 26
A box of candy is $4.25 and a drink is $3.50
Step-by-step explanation:
Let c represent the cost of a box of candy and let d represent the cost of a drink
c + 3d = 14.75
2c + 5d = 26
Solve by elimination by multiplying the top equation by -2
-2c - 6d = -29.5
2c + 5d = 26
Add them together
-d = -3.5
d = 3.5
Plug in 3.5 as d into one of the equations to solve for c
c + 3d = 14.75
c + 3(3.5) = 14.75
c + 10.5 = 14.75
c = 4.25
So, a box of candy is $4.25 and a drink is $3.50

CAN SOMEONE HELP I WILL GIVE BRAINLIST PLEASE!
Answer:
1) Perimeter = 34 yards
If one of the width = 5 yards then the other width = 5 yards so 10 yards
34 yards - 10 yards = 24 yards divide by 2
Length = 12 yards
2) Perimeter = 24 m of fencing
Width = 7 m
2nd Width = 7 m
24 m - 14 m = 10 m divide by 2
Length = 5 m
3) The perimeter of a square is 12 feet
Note: All sides in a square is equal!

It takes a turtle 3 ¼ hours to walk 1 ½ miles. How many hours does it take to walk one mile?
Answer:
It will take 6/13 hours to walk one mile
Step-by-step explanation:
Here, we want to calculate the number of hours it take to walk one mile
From the question, 1 1/2 miles take 3 1/4 hours
the number of hours it will take to walk 1 mile will be;
1 1/2 divided by 3 1/4
= 3/2 divided by 13/4
= 3/2 * 4/13 = 6/13 hours

PLEASE HELP I NEED THIS I AM GIVING LOTS OF POINTS!!!!!!!!!!! How many 1/3 inch cubes does it take to fill a box with width 2 2/3 inches, length 3 1/3 inches, and height 2 1/3 inches?
===================================================
Work Shown:
Let's find out how many smaller cubes are needed to go along the 2 & 2/3 inch side length of the bigger box.
First convert to an improper fraction
2 & 2/3 = 2 + 2/3 = 6/3 + 2/3 = 8/3
Divide this over the side length of the small cube to get
8/3 divided by 1/3 = (8/3)*(3/1) = 24/3 = 8
So we need exactly 8 small cubes along the 2 & 2/3 inch side length.
Let A = 8 so we can use this later.
------------------
Repeat the same steps for the 3 & 1/3 inch side length
3 & 1/3 = 3 + 1/3 = 9/3 + 1/3 = 10/3
10/3 divided by 1/3 = (10/3)*(3/1) = 30/3 = 10
We need 10 cubes along the 3 & 1/3 inch side length.
Let B = 10.
------------------
Repeat for the 2 & 1/3 inch side length
2 & 1/3 = 2 + 1/3 = 6 + 1/3 = 7/3
7/3 divided by 1/3 = (7/3)*(3/1) = 21/3 = 7
We need 7 cubes along the 2 & 1/3 inch side length
Let C = 7
------------------
Multiply out the values of A,B,C to get
A*B*C = 8*10*7 = 560
This means we need 560 cubes that are each 1/3 of an inch along the the side to fill up a box that has dimensions of 2 & 2/3 inches by 3 & 1/3 inches by 2 & 1/3 inches.
