Find three consecutive even integers such that four times
the first minus the third is six more than twice the second.
Answer:
simple just follow me and mark it brainliest
Step-by-step explanation:
LET THE THREE CONSECUTIVE EVEN INTEGERS BE
(x+2) ,(x+4) ,(x+6)
then
according to the question
4(x+2) – (x+6) = 2(x+4) + 6
4x + 8 – x – 6= 2x + 8+6
3x +2 = 2x + 14
3x – 2x= 14 –2
x= 12
the numbers are
14
16
18
Answer:
The three numbers are 14, 16, 18.
Step-by-step explanation:
Consecutive even integers differ by 2.
You can let the smallest of the three numbers equal x. Then the other two numbers are x + 2 and x + 4.
Now use x, x + 2,and x + 4 to represent the 3 numbers and follow the directions to write an equation. The equation will have only one variable, x, so you can solve for x.
"four times the first" -----> 4x
"minus the third" -------> -(x + 4)
"is" -----> =
"six more than twice the second" ------> 2(x + 2) + 6
Put all the pieces in boldface together to arrive at your equation.
4x - (x + 4) = 2(x + 2) + 6
Simplify the parentheses on both sides by distributing.
4x - x - 4 = 2x + 4 + 6
Combine like terms on both sides.
3x - 4 = 2x + 10
Subtract 2x from both sides.
x - 4 = 10
Add 4 to both sides.
x = 14
The smallest number is 14.
x + 2 = 14 + 2 = 16
x + 4 = 14 + 4 = 18
Answer: The three numbers are 14, 16, 18.
Dominic is going to attend a baseball game on Saturday afternoon. He has a total of $40 he can spend. The ticket cost is $22, and the parking cost is $7. He intends to spend his remaining money on team window decals that cost $4.50 each. What is the greatest number of decals Dominic can buy? A 2 decals B 3 decals C 4 decals D 5 decals
Answer: A. 2 Decals
Step-by-step explanation: time4learning
The requried Dominic can buy a maximum of 2 decals.
What is simplification?Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.
Dominic has $40 to spend, and he will spend $22 for the ticket and $7 for the parking. So, he will have:
$40 - $22 - $7 = $11
left to spend on team window decals.
Each decal costs $4.50, so we can divide the amount Dominic has left by the cost of each decal to find the maximum number of decals he can buy:
$11 ÷ $4.50 ≈ 2.44
Since we can't buy a fraction of a decal, we need to round down to the nearest whole number. So, Dominic can buy a maximum of 2 decals.
Therefore, the answer is A, 2 decals.

10 laps around track each day. Each lap around the track is 400 meters. How many day will take kali to run a total 12 kilometers
Answer:
3 days
Step-by-step explanation:
First, let's convert 400 meters to km (kilometers):
To find km from m we divide the meters by 1000:
400/1000 = 0.4
Therefore, there are 0.4 km in 1 meter.
Kali runs 10 laps every day, since 1 lap is 0.4 km we can multiply 10 by 0.4 to see how many kilometers they run in 1 day:
(10)(0.4) = 4
Kali runs 4 kilometers every day
Now, we can find how long it will take Kali to run a total of 12 kilometers by dividing 12 by 4
12/4 = 3
It will take Kali 3 days to run a total of 12 kilometers.
I hope this helps!!

Would the three squares below join together to make a right triangle? Why or why not? picture shows squares
Answer:
Yes.
The first has an area of 9, so each side is three.
The second has an area of 16, so each side is four.
Each side of the third square is given as 5.
So the triangle has sides of 3, 4, and 5.
3²+4²=5²
9+16=25
25=25 It works given the Pythagorean theorem.

Please help me with this question please help me I beg you
Step-by-step explanation:
Given
f(x) = 5 / 2x - 1
f^-1( x) = ?
Let
y = f(x)
y = 5/2x - 1
Interchanging the roles of x and y we get
x = 5/2y - 1
2y - 1 = 5/x
2y = 5/x - 1
y = (5/x - 1)/ 2
f^-1(x) = ( 5/x - 1) / 2

what is the slope of the line that passes through the point -1 negative 10 + negative one negative to write your answer in simplest form what is the answer
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Point\ 1: -1, -10[/tex] --- [tex](x_1,y_1)[/tex]
The second point is incomplete. So, I will make assumptions
[tex]Point\ 2:1, -4[/tex] -- [tex](x_2,y_2)[/tex]
Required
Calculate the slope (m)
This is calculated as:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{-4 - (-10)}{1 - (-1)}[/tex]
[tex]m = \frac{-4 +10}{1 +1}[/tex]
[tex]m = \frac{6}{2}[/tex]
[tex]m =3[/tex]
Using the assumed values, the slope is 3

A plant's ability to reproduce and contribute to the survival of its own species is assured when flowering occurs at the right point in time. If flowering starts too early, the result may be a poor crop of biomass as well as fruit.
During the first week of winter, a business used 1/6 of a tank of heating oil. It used two times as much oil in the second week as it did in the first week. It used another 1/8 of a tank during the third week. A delivery of ½ tank was made at the end of the third week. The final fuel gauge shows a line between ½ and F. How much fuel did the business start with?
Answer:
The business started with 23/24 of their tank full
Step-by-step explanation:
Step 1.
Find the LCM of the denominators (2,6 and 8)
=24
Step 2.
Change all the fractions to have a denominator of 24
1/6=4/24
1/8=3/24
1/2=12/24
3/4= 18/24
Step 3.
Work backwards
18/24-12/24
=6/24+3/24
=9/24+(2×4/24)
=17/24+6/24
=23/24

ABCD is a square and triangle DEF is equilateral. Triangle ADE is isosceles with AD=AE calculate size of angle AEF
Answer:
∠AEF = 90°
Step-by-step explanation:
The size of angle AEF is given below:
Given that
ABCD is Square
CDF is a straight line
∠ADF = 90°
And triangle DEF is an Equilateral Triangle
So,
∠FDE = 60°
Now
∠ADE = 90° - 60°
= 30°
AD = AE
∠AED = 30°
∠DEF = 60° because of an equilateral triangle
Now
∠AEF = ∠AED + ∠DEF
∠AEF = 30° + 60°
∠AEF = 90°
