I need the steps and answers please
Answer:
you could use 3,5,1 as your answer, but I have a feeling you are expected to answer x = 15 / (1 - 2y) It depends on what you have been told.
Step-by-step explanation:
Take out x as a common factor.
I suspect there are many possible answers -- well more than 1 unique answer.
x (1 - 2y) = 15 Divide by 1 - 2y
x = 15 / (1 - 2y)
1 - 2y = 3
-2y = 2
y = -1
What does that give you?
1 - 2(-1) = 3
x = 15/3
x = 5
1- 2y = 5
- 2y = 4
y = -2
x = 15 / 5
x = 3
1 - 2y = 15
-2y = 15 - 1
-2y = 15
y = - 7
x = 15 / 15 = 1
please help
it would be very appreciated
X/3 - X/6 = 2
What is the value of x how do I do it?
Answer:
Value of X is 18
Step-by-step explanation:
x/3 - x/6 = 2
multiply first fraction by 3 so u get X by its self then multiply the 2 by 3
x - x/6 = 6
then multiply the fraction by 6 to get X by itself then multiply the 6 by 6 because what u do to one side u have to do to the other
2x/2 = 36/2
x= 18

Which translation vectors could have been used for the pair of figures?
select EACH correct answer
Answer:
The translation vector can be drawn on the coordinate grid or written as
\vec{v}=\langle a,b\rangle
v
=⟨a,b⟩
. For example, a translation vector that moves a figure
3
3
units right and
2
2
units down can be represented mathematically as
\vec{v}=\langle3,-2\rangle
v
=⟨3,−2⟩
, or graphically as
It doesn’t matter where the vector is positioned in the plane. In this figure, the vector starts at
(1,1)
(1,1)
and ends at
(4,-1)
(4,−1)
. But the initial point and terminal point of the vector are irrelevant. What matters is the length of the vector and the direction in which it points, so all you have to look at is how many units the vector moves in the
y
y
-direction and how many units the vector moves in the
x
x
-direction.

What is the perimeter of the triangle?
Answer:
D
Step-by-step explanation:
When you add up
[tex](4m^3+2m^2-m)+(4m^2+2m^2-2m)+(7m^3-3m^2+2m)[/tex],
you have [tex]15m^3+m^2-m[/tex],
which is what D is.
Side note:
You only add up the exponents when you multiply.
[tex]4 {m}^{3 } \: + 2 {m }^{2} \: - \: m \: [/tex]
[tex]7 {m}^{3} \: - 3 {m}^{2} + \: 2m[/tex]
[tex]4 {m}^{3} \: + 2 \: {m}^{2} \: - 2m[/tex]
Therefore ,perimeter of triangle is sum of all sides :-[tex] = (4 {m}^{3} + 2 {m}^{2} - m) + (7 {m}^{3} - 3 {m}^{2} 2m) + (4 {m}^{3} + 2 {m}^{2} - 2m)[/tex]
[tex] = 4 {m}^{3} + 7 {m}^{3} + 4 {m}^{3} + 2 {m}^{2} - 3 {m}^{2} + 2 {m}^{2} - m + 2m -2m [/tex]

Inches

?
192
Intro
Done
9514 1404 393
Answer:
96 inches in 8 ft
Step-by-step explanation:
The number of inches is 12 times the number of feet. (Each foot is 12 inches.)
_____
Additional comment
The number of inches is proportional to the number of feet, so the number of inches in 8 feet will be half the number of inches in 16 feet. You may find it easier to divide the table value 192 inches by 2 than to multiply 8 feet by 12.

1. How can you use addition to check
that 1.55 cm is the difference in the
wingspans of the two butterflies?
The check using addition, the value of difference is added to the smaller value which should give the larger wingspan value.
The value of the wingspan of the butterflies aren't given, however, we could take hypothetical values for the wingspan of the two butterflies :
Wingspan of Butterfly A = 5.55 cm
Wingspan of Butterfly B = 4 cm
This means that, the difference in the wingspan is :
Wingspan of A - Wingspan of B
5.55 cm - 4 cm = 1.55cm
To check using addition :
The value of the difference added to the value of the butterfly with the lower wingspan should give the value of the wingspan of butterfly B(larger wingspan).
This means:
4cm + 1.55cm = 5.55 cm
Hence, the value of the difference is correct.

The ratio of Mr Lim's salary to that of Mr Li is 7:8. If Mr Lim's salary is $2450, what is Mr Li's salary?
Answer:
Mr . Li's salary = $ 2950
Step-by-step explanation:
Ratio = 7 : 8
Total part = 7+8 = 15
Mr. Lim's part = 7/15
Total salary = $ x
Mr. Lim's salary = $ 2450
[tex]\dfrac{7}{15}*x= 2450\\\\\\x = 2450*\dfrac{15}{7}\\\\[/tex]
