yes of course...
just like
saying 2=x is equivalent to x=2
similarly x<3 is equivalent to 3>x

Duval scored 10 more than 2 times the number of points scored by a
player, x. Which equation shows the number of points, y, Duval scored?
Answer:
2x + 10 = y
Step-by-step explanation:
The term 10 more is plus 10, and 2 times the "number" which we know we can label as "x". 2x + 10 is the equation and we are told that y is the number of points so 2x + 10 = y is the answer.
Hope that helps, and have a great day!
Given: g(x) = 3x² + 2 and h(x) = 2x + 2
Find: g(h(x))
Step-by-step explanation:
g(x) = 3x² + 2
h(x) = 2x + 2
g(h(x)) = g([2x + 2]) = 3[2x+2]² + 2
= 3[4x² + 8x + 4] + 2
= 12x² + 24x + 12 + 2
= 12x²+ 24x + 14

Find the midpoint of the line segment joining the two points.
(1.8, -3.4) and (-0.4, 1.4)
Answer:
(0.7, -1)
Step-by-step explanation:
To find the coordinates for the midpoint you add each coordinate together and divide by 2.
M = ([tex]\frac{1.8 - 0.4}{2}, \frac{-3.4 + 1.4}{2}[/tex])
M = [tex](\frac{1.4}{2}, \frac{-2}{2})[/tex]
M = (0.7, -1)
A T-shirt shop charges $15 for an adult shirt and $12 for a youth shirt. The total charge for a shirt order was $489.

We can see that the diagonal distance from the fire pit to the tree is 6 units, if you count, with a slope of 1, meaning that we only have to stay on that diagonal.
A third of 6 is 2, so we'll just go 2 units in that diagonal, putting us at the point [tex](4,3)[/tex].
Hope this helps.
頑張って!

The quotient of six and the sum of a number and eight
Answer:
6
——
x+8
Step-by-step explanation:
The quotient of six (6) and the sum of a number and eight (8) is equal to [tex]\frac{x + 8}{6}[/tex]
Let the unknown number be x.
In Mathematics, quotient simply means to divide a number by another number without any remainder.
Translating the word problem into an algebraic expression, we have;
The sum of a number and eight = [tex]x + 8[/tex]
Quotient of six (6) and the sum of a number and eight (8) is equal to;
[tex]\frac{x + 8}{6}[/tex]
In conclusion, the quotient of six (6) and the sum of a number and eight (8) is equal to [tex]\frac{x + 8}{6}[/tex]

how to do this question plz
Answer:
The answer is yes.
Step-by-step explanation:
All you have to do is substitute the y, which is 5, and the x, which is 2, into the equation. When you solve it the answer in the end will be 5=5, which means that point (2,5) does line on that line.
One of the two equal factors of a number is
Answer:
If the two factors are equal (the same), like 4*4=16, then each of them is called a "square root." Note: a cube root is one of three equal factors of a number, for example, 2 is the cube root of 8 (that is, 2*2*2=8).

Ms. G, Mr. Adams, and Ms. Leahman are going for a bike ride together on Saturday. They want to meet each other in the city but they all live in Bedstuy. Ms. G and Ms. Leahman have to bike 4 miles there, Mr. Adams is 5 miles away. They meet each other in the city and bike 2 miles together. Then they all return home the same way. How many miles did they all bike in total on Saturday?
Answer: 22 miles
Step-by-step explanation: Ms. G and Ms. Leahman both bike the same amount on Saturday:
4 miles to go to the city;
2 miles with Mr. Adams;
4 miles back to Bedstuy;
Then, both biked:
4 + 2 + 4 = 10 miles
Now, Mr. Adams bikes:
5 miles to go to the city;
2 miles together with the other two;
5 miles back to Bedstuy;
Then, he biked, in total:
5 + 2 + 5 = 12miles
So, the three of them biked, in total:
10 + 12 = 22
On Saturday, Ms. G, Mr. Adams and Ms. Leahman biked, in total, 22 miles.

k/7 = 10 solve for k
Answer:
k=70
Step-by-step explanation:
to get k by itself you need to multiply k/7 by 7, and you multiply on both sides. 10 times 7 =70
Answer:
Step-by-step explanation:
k/7 = 10
or, k = 7*10
Therefore, k=70.

A can do a work in 14 days and working together A and B can do the same work in 10 days. In what time can B alone do the work? (i dont get this one, please explain :)
Answer:
35 days
Step-by-step explanation:
A = 14 days
It means per day, work done by A= 1 / 14
A+B = 10 days
Work done by A and B per day = 1 / 10
In what time can B alone do the work?
To solve this, we have
A+B = A alone + B alone
1/10 = 1/14 + B alone
Subtract 1/14 from both sides
1/10 - 1/14 = 1/14 + B alone - 1/14
14-10/140 = B alone
4/140 = B alone
B alone= 1 / 35
Work done of B alone = 1/35
B alone will do the work in 35 days
Answer:
35 days.
Step-by-step explanation:
A can do the work in 14 days: per day work done by A=1/14
A and B can do the work in 10 days: per day work done by A and B=1/10
Work is done by B per day=1/10–1/14=7/70-5/70=(7–5)/70=2/70=1/35.
So, B takes 35 days.
