The solution to the following equation is x=0
6x+7= 1/2x+7
True
or
False
(The 1/2 is a fraction)
Answers
Explanation:
If X=0 then that would make the problem 6(0)+7=1/2(0)+7. Anything multiplied by 0 is 0 so that would cancel the 6 and the 1/2. That means that you would be left with 7=7
Answer:
True
Step-by-step explanation:
To see if that is the solution, lets solve the equation.
6x + 7 = 1/2x + 7
Subtract 1/2x from each side to bring it to the right
6x - 1/2x + 7 = 7
Subtract 7 from each side to bring it to the left
6x - 1/2x = 7 - 7
Simplify it
5.5x = 0
Divide 5.5 from each side to leave x alone.
x = 0
The answer is true. I hope this helps!

Answer:
4/12 cups
Step-by-step explanation:
The amount needed is the product of the recipe amount and the amount of a recipe that is being made.
(2/3 cup/recipe)(2/4 recipe) = (2·2)/(3·4) cups = 4/12 cups

What is the slope of the line that passes through the points (4, 6)(4,6) and (-16, -18) ? (−16,−18)? Write your answer in the simplest form.
Answers
The slope of the line that passes through the points (4, 6)(4,6) and (-16, -18) is to be considered as the 1.2.
Calculation of the slope of the line:here we used the following formula
So,
[tex]= y_2-y_1\div x_2-x_1[/tex]
So,
-18-6=-24
And,
-16-4=-20
Now
[tex]= -24\div -20[/tex]
= 1.2
Hence, The slope of the line that passes through the points (4, 6)(4,6) and (-16, -18) is to be considered as the 1.2.

The slope of the line that passes through the points (4, 6) and (-16, -18) is; 6/5.
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line. Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.
[tex]m = \dfrac{y-q}{x-p}[/tex]
Given that the line that passes through the points (4, 6) and (-16, -18)
WE need to find the slope of the line.
Since, [tex]m = \dfrac{y-q}{x-p}[/tex]
Therefore, m = -18 - 6 / -16 - 4
m = 24 / -20
m = 6/5
Hence, The slope of the line that passes through the points (4, 6) and (-16, -18) is; 6/5.

The water park is a popular field trip destination. This year the senior class at high school a and high school b both planned trips there. The senior class at high school a rented filled 4 vans and 14 buses with 742 students. High school b rented and filled 4 vans and 6 buses with 350 students. Each van and each bus carried the same number of students. Find the number of students in each van and in each bus.
Answers
x = buses
y = vans
our equations will look something like this :
4x + 14y = 742 &’
4x + 6y = 350
let’s solve for y first . we need to cancel out our x’s so we turn on of them into a negative and since both of them have the same common factor we don’t need to find it . let’s multiply the bottom equation by ( -1 )
here’s what our new equations look like :
4x + 14y = 742
-4x - 6y = -350
now that our x’s are cancelled out we add our y’s and our totals :
14y + ( -6y ) = 8y
742 + ( -350 ) = 392
we want y alone so we divide :
392/8 = 49
y = 49
now we can substitute 49 for y :
4x + 14 ( 49 ) = 742
4x + 6 ( 49 ) = 350
we can multiply those numbers together :
4x + 686 = 742
4x + 294 = 350
now we add downward :
8x + 980 = 1,092
we need x alone so we subtract 980 from both sides :
8x = 112
divide by 8 :
x = 14
now , we can substitute 14 for x and 49 for y to check our work :
4 ( 14 ) + 14 ( 49 ) = 742
742 = 742 ✅
4 ( 14 ) + 6 ( 49 ) = 350
350 = 350 ✅

Answer:
Step-by-step explanation:
Diameter is the longest line that you can draw in a circle passing through the centre of the circle.
Radius is the line joining the centre of the circle to any point on the circumference.
Explanation:
Diameter is the ratio of the circumference of the circle to the irrational constant 'pi' (3.1415...). Radius is the half of the diameter.
D=2x radius and radius =D/2
Actually pi is defined to be the ratio of the circumference of the circle to the diameter of the circle. Therefore, you can solve for the diameter from that equation.
π=C/D , D=C/π Or , C=π x D
