Answer:
2( 2x -3)(x- 5)
Step-by-step explanation:
step 1 . factor 2 out ( because when you multiply the 2 again with the equation it will give you the main equation)
2 ( 2x^2 - 13x + 15 )
step 2 . factor now by regrouping
2( 2x- 3 )( x - 5)
hope it helps

When doing decimals, what does a dot over a number mean? For example, take 24.671, but theres a small dot over the numbers 6 and 1. What do I do and what does it mean?
Step-by-step explanation:
The dot is called a decimal point. It is also called the decimal separator. It separates whole numbers from fractional numbers.
In this example;
24.671
The numbers before the point, 24 is the whole number
The numbers after the point, 671 are the fractional portion of the number. They represent 6 tenths, 7 hundredths and 1 thousandths.
Also, the number of digits after the point tells you how many decimal place the number is in. In this example the number of decimal places is 3.
In triangle 4JKL, we have JK = 9 and KL = 15. If JL is an integer, what are the largest and smallest possible values for JL?
Answer:
The largest possible value is 23
The smallest is 7
Step-by-step explanation:
To get the length of JL, we use the triangle inequality theorem
The theorem is that the sum of the measure of any two sides of a triangle must be greater than the measure of the third side of the triangle for the triangle to exist
With respect to this, 9 + 15 must be greater than JL
since JL is an integer ( integers are whole numbers); we have the following
9 + 15 = 24
JL is less than 24; so the nearest integer closest to 24 is 23
Now, let us get the smallest possible value
For the smallest possible value;
Let us call that x
9 + x > 15
15 + x > 9
From the first inequality;
x > 15-9
x > 6
The smallest integer greater than is 7
So the smallest possible value for JL is 7 and the largest is 23
Jenna bought enough lattes for all her friends. Each latte was $3.50
and she gave the barista a $20 bill, who then gave her back $2.50
in change. Write an equation modeling this, with x as the cost per late
How many lattes did she buy?
Answer: 5 lattes
Step-by-step explanation: Our equation is 20 − 3.5x = 2.5, which means x = 5 lattes.
Answer:
Step-by-step explanation:
y=3.5x (cost function where y is cost and x is the number of lattes)
20-2.5=3.5x
17.5=3.5x
5=x
So she bought 5 lattes.

Write two division equations for each multiplication equation. 15⋅25=6 15 ⋅ 2 5 = 6 6⋅43=8 6 ⋅ 4 3 = 8 16⋅78=14
Answer:
[tex](a)[/tex] [tex]\frac{30}{5} = 6[/tex] and [tex]\frac{60}{10} = 6[/tex]
[tex](b)[/tex] [tex]\frac{24}{3} = 8[/tex] and [tex]\frac{96}{12} = 8[/tex]
[tex](c)[/tex] [tex]\frac{112}{8} = 14[/tex] and [tex]\frac{28}{2} = 14[/tex]
Step-by-step explanation:
Given
[tex](a)\ 15 * \frac{2}{5} = 6[/tex]
[tex](b)\ 6 * \frac{4}{3} = 8[/tex]
[tex](c)\ 16 * \frac{7}{8} = 14[/tex]
Required
Write 2 division equations
[tex](a)\ 15 * \frac{2}{5} = 6[/tex]
Express 15 as 15/1
[tex]\frac{15}{1} * \frac{2}{5} = 6[/tex]
Multiply numerator and denominator
[tex]\frac{30}{5} = 6[/tex] --- This is (1)
Multiply the fraction by a common term (e.g. 2)
So, we have:
[tex]\frac{30*2}{5*2} = 6[/tex]
[tex]\frac{60}{10} = 6[/tex] ---- (2)
[tex](b)\ 6 * \frac{4}{3} = 8[/tex]
Express 6 as 6/1
[tex]\frac{6}{1} * \frac{4}{3} = 8[/tex]
Multiply numerator and denominator
[tex]\frac{24}{3} = 8[/tex] --- This is (1)
Multiply the fraction by a common term (e.g. 4)
So, we have:
[tex]\frac{24*4}{3*4} = 8[/tex]
[tex]\frac{96}{12} = 8[/tex] ---- (2)
[tex](c)\ 16 * \frac{7}{8} = 14[/tex]
Express 16 as 16/1
[tex]\frac{16}{1} * \frac{7}{8} = 14[/tex]
Multiply
[tex]\frac{112}{8} = 14[/tex] ---- This is (1)
Divide the fraction by a common term (e.g. 4)
[tex]\frac{112/4}{8/4} = 14[/tex]
[tex]\frac{28}{2} = 14[/tex]
solve for x: tan(180-ø).tan(90+ø)+xcos(90+ø).(cos90-ø) =sinø.(sin180-ø)
Answer:
Below.
Step-by-step explanation:
tan(180-ø).tan(90+ø)+xcos(90+ø).(cos90-ø) = sinø(sin180-ø)
xcos(90+ø).(cos90-ø) = sinø(sin180-ø) - tan(180-ø).tan(90+ø)
x = (sinø(sin180-ø) - tan(180-ø).tan(90+ø)) / cos(90+ø).(cos90-ø)
x = - (sin^2ø + tanø(tan(90+ø)) / cos^2ø

X+4=19-2x
8z - 20 =z +15
Answer:

Step-by-step explanation:

x=12÷2
x=6
x+4=19-2x
x+2x=19-4

plzz mark me as brainliest
Answer:
3x-2=x+10
x=6
x+4=19-2x
x=5
8z-20=z+15
z=5
Step-by-step explanation:
3x-2=x+10
+2 on both sides
3x-2(+2)=x+10(+2) => 3x=x+12
subtract x on both sides
3x(-x)=x(-x)+12 => 2x=12
divide 2 on both sides
2x/2=12/2
= x=6
x+4=19-2x
subtract 4 on both sides
x+4(-4)=19(-4)-2x => x=15-2x
add 2x on both sides
x(+2x)=15-2x(+2x) => 3x=15
divide 3 on both sides
3x/3=15/3
= x=5
8z-20=z+15
subtract z on both sides
8z(-z)-20=z(-z)+15 => 7z-20=15
add 20 on both sides
7z-20(+20)=15(+20)
7z=35
divide 7 on both sides
7z/7=35/7
= z=5
if 1/4x +2y= 11/4
and - 6y - x = 7, what is
half of y?
Answer:
y/2 = 4.5
Step-by-step explanation:
1/4x + 2y = 11/4
distribute by 4 to eliminate fractions
x + 8y = 11
+ -x - 6y = 7
2y = 18
y = 9
half of 9 = 4 1/2

Use properties of equality to isolate y.
x + y = 10
y = ?
Answer:
x+y=10
y=10-x
To isolate y, you subtract x on both sides.

∠1 and ∠2 are complementary angles. If ∠1 measures 35º, what is the measure of ∠2?
Answer:
55 degrees
Step-by-step explanation:
Complementary angles are two angles that equal 90 degrees together so if one angle is 35 degrees then the other must be able to add towards that to make 90 degrees
90=35+∠2
-35 -35
55=∠2

Solve for the variable
Answer:
40
Step-by-step explanation:
Try to get the variable alone by dividing 5/8 on both sides of the equations.
That cancels out the 5/8 on the left leaving u and the 25 on the right turns into 40. It turns into 40 because 25 divided by 5/8 equals 40.
Answer:
40
Step-by-step explanation:
Multiply both sides by 8/5

Find the common solution.
x = - y + 10
x = y + 4
Type answer as an ordered pair.
Answer:
Step-by-step explanation:
x = -y + 10
Substitute into the second equation
-y + 10 = y + 4
-2y = -6
y = 3
Plug into first or second equation.
x = -3 + 10 = 7
x = 3 + 4 = 7
So the ordered pair is (7,3)

Complete Question
Mis. Jackson wants to rent a van for a week it will cost a weekly fee plus 0.20 per mile driven let m equal the number of miles Ms. Jackson drives during the week write an algebraic expression that shows a week rent Jackson will pay for the van for the week
Answer:
A = w + 0.20m
Step-by-step explanation:
Step 1
We find the equation for the total amount spent in a week
The total amount to rent the van in a week = A
Weekly fee = w
Number of miles = m
Therefore, thw algebraic expression that shows a week rent Jackson will pay for the van for the week is
A = w + 0.20m
