Answer:
inverse of 5/42 = -42/5 = -8 2/5 = -8.4
inverse of 15/42 is flipped -42/5 = -2.8
The decimal steps are;
if 5/42 then show -1/1 = 5/42 = 42/5 = 8 2/5
= 8.4
if 15/42 then -1/1 ÷15/42 = -14/5
= -2.8
Step-by-step explanation:
if the question was 15/42 then we divide by -1 /15/42 = -42 / 15
so we can divide all by -1 or -1/1
The calculation steps are ;
-1/1÷ 15/42
= -1/1×42/15
= -1 × 42 / 1 × 15
= -42/15
The decimal steps are;
if 5/42 then show -1/1 = 5/42 = 42/5 = 8 2/5
= -8.4
if 15/42 then -1/1 ÷15/42 =–14/5
= –2.8

A carpenter wants to cut a 45 inch board into two pieces such that the longer piece will be 7in longer than the shorter I'll mean you should each piece be
Answer:
19 inches and 26 inches
Step-by-step explanation:
first you have to take 45-7=38
then 38÷2=19
so 19 is one board
last you take 19+7=26
so 26 is the other board

in the right triangle, the legs have lengths 5 and 7 . Express the length of the hypotenuse in radical form?
Answer:
[tex]\sqrt{74}[/tex] units
Step-by-step explanation:
Hi there!
We can use the Pythagorean theorem to solve this question:
[tex]a^2+b^2=c^2[/tex] where a and b are the two legs and c is the hypotenuse
Plug in the two legs 5 and 7 and solve for c, the hypotenuse:
[tex]5^2+7^2=c^2\\25+49=c^2\\74=c^2\\c=\sqrt{74}[/tex]
Therefore, the length of the hypotenuse in radical form is [tex]\sqrt{74}[/tex] units.

Answer:
y = 122
Step-by-step explanation:
let us start by adding some angles ourselves.
we are going to add angles at the right side of 150 and at the left of y
we can call the angle beside 151 x and the angle beside y A
first of all, let us find the value of x
now, angles 151 and x add up to 180 because angles on a straight line add up to 180 and the two angle are on a straight line of their own
which means;
151 + x = 180
when we collect like terms,
x = 180 - 151
x = 29
therefore, our x = 29
next, we find A
now, angles 29 ( our x ), 93 and our A all add up to 180 because the sum of angles in a triangle is 180 and our angles are in a triangle ( at least an upside down one with lines shooting out from every end )
that is;
29 + 93 + A = 180
collect like terms
A = 180 - 29 - 93
A = 180 - 122
A = 58
so, now that we have our angle A, the next thing to do is the same thing we did to get angle x,
we can see that A and y are both on a straight line of their own which means that they both add up to 180 degrees
that is;
A + y = 180
and we know that A = 58
so;
58 + y = 180
we collect like terms to have
y = 180 - 58
y = 122
therefore, y = 122
if you might have noticed, y is the same as x and 93
and that is correct because according to a rule in math, the value of an exterior angle of a triangle is equal to the sum of its opposite interior angles of the triangle. this can be explained using our question above

Answer: 6 2/25
Step-by-step explanation:
8/100 + 6
6= 6/1
6/1 + 8/100= 6 6/25 = 6.08
Answer:
6.08
Step-by-step explanation:
1. 1 hundredth is equal to 0.01 because it's 1 unit of out 100.
2. 1 whole is equal to 1 because it's just one, whole unit.
3. Given this information, 8 hundredths would be 0.08 and 6 wholes would be 6.
4. Now, to find the sum, just add these two numbers together:
[tex]6+0.08[/tex] [tex]6.08[/tex]Therefore, the answer is 6.08.
-6+6y^2 factorize this expression
Answer:
- 6(1 - y)(1 + y)

= - 6(1 - y)(1 + y)
Liam is setting up folding chairs for a meeting. If he arranges the chairs in 5 rows of the same length, he
has 5 chairs left over. If he arranges the chairs in 3 rows of that same length, he has 15 left over. How many
chairs does Liam have?
Liam has
chairs.
Answer:
30 Chairs
Step-by-step explanation:
I will solve this problem using algebra and try to explain in detail.
We can form two equations with the information given to us.
Firstly, 5 times a length of chairs (I will call this unknown length of chairs x), plus 5 left over chairs, equals the total number of chairs (I will call the total number of chairs y).
5x + 5 = y
Secondly, 3 times a length of chairs (I will call this unknown length of chairs x), plus 15 left over chairs, equals the total number of chairs (I will call the total number of chairs y).
3x + 15 = y
Since both equations are equal to y, they are equal to each other
5x + 5 = 3x + 15
Take 5 away from both sides of the equals, and take away 3x from both sides of the equals
5x - 3x = 15 - 5
2x = 10
Divide both sides by 2
x = 5 chairs
Put this back into either the first equation or the second to solve for y
3 (5) + 15 = y
15 + 15 = y
y = 30 chairs

Find the slope of -10x + 2y = 8 using slope intercept form
Original question: -10x + 2y = 8
Step 1: 2y = 10x + 8
What was added to both sides from the original question to get the equation in Step 1?
I will give brainiest to who answers this! Thanks a million
Answer:
you subtracted 2y from both sides to each side getting 2y = 10x +8
Step-by-step explanation
Step-by-step explanation:
10x was added to both sides which resulted in
2y = 10x + 8
now divide both sides by 2
y = 5x + 4
The slope is 5 and the y intercept is (0,4)

As per the given condition m ∠LOM = m ∠JKI, m ∠MON = m ∠IKH it is proved that m ∠LON = m ∠HKJ as they are congruent angles.
What are congruent angles?"Congruent angles is defined as the angles with equal measure."
According to the question,
In the given figure of the angles,
m ∠LOM = m ∠JKI (given congruent angles) _____(1)
m ∠MON = m ∠IKH (given congruent angles) _______(2)
Add both the side angle m ∠MON in (1) we get ,
m ∠LOM + m ∠MON = m ∠JKI + m ∠MON
Replace angle m ∠MON = m ∠IKH from (2) on right hand side we get,
m ∠LOM + m ∠MON = m ∠JKI + m ∠IKH ____(3)
m ∠LOM + m ∠MON = m ∠LON ( M is the interior point of ∠LON) ___(4)
m ∠JKI + m ∠IKH = m ∠HKJ ( I is the interior point of ∠HKJ) ___(5)
Form (3) , (4) and (5) we get,
m ∠LON = m ∠HKJ (Congruent angles)
Hence, form the given condition it is proved that m ∠LON = m ∠HKJ , are congruent angles.
