Step-by-step explanation:
y = 4x-1
2x+y = 5
2x+(4x-1) = 5
6x - 1 = 5
6x = 6
x = 1
Answer:
(1,3)
Step-by-step explanation:
Since we already have the variable to it self, we can substitute y=4x-1 into 2x+y=5.
So it would be 2x+(4x-1)=5
Remove the parentheses
Combine like terms
Move the constant to the right
Divide 6 on both sides to get the variable by it self.
x=1
Then we substitute x=1 into y=4x-1, so..
y=4(1)-1
y=4-1
y=3
So the answer would be (1,3).

Give one pair of supplementary angles and one pair of vertical angles shown in the figure below.
Answer:
Supplementary- 5 and 6
Vertical- 1 and 6
Step-by-step explanation:
5 and 6 are supplementary, because they make a straight line together. 1 and 6 are vertical angles, bu the vertical angles congruence theorem.

-37=5w-7
w=
Please I need an answer ASP
Answer:
-6
Step-by-step explanation:
-37+7=5w
-30=5w
w=-30÷5
w=-6
Answer:
w=-6
Step-by-step explanation:
-37=5w-7
-37+7=5w-7+7 (add 7 both sides)
-30/5=5w/5 (divide both sides by 5 to remove 5 and make it equal to w)
-6=w or w=-6

Describe how to find the slope and y intercept of 2x+3y=6, then describe how would you graph the line.
Answer:
Step-by-step explanation:
In order to convert the standard form equation we are given now into slope-intercept form, we need to get y on one side by itself and solve for y.
Work.
2x+3y=6
-3y -3y
2x=6-3y
-6 -6
2x-6=-3y
/-3 /3
-2/3x+2=y
y=-2/3x+2
Now that it is in slope intercept form, we can identify the y intercept and slope.
y-int=(0,2), slope=-2/3
I would graph the line by first plotting the y-intercept at the point (0,2). From there, I would plot the slope by going down 2 blocks and moving 3 blocks to the right. Then I would connect the two points with a ruler to get my line since you only need two points to create a line.

Help! 1/6 of 2 yards is how many feet?
Answer:
1 foot
Step-by-step explanation:
1 yard = 3 ft
[tex]2*1 yard= 2*3feet[/tex]
2 yards = 6 feet
[tex]\frac{1}{6}[/tex] (2 yards) = [tex]\frac{1}{6}[/tex] (6 feet)
So, [tex]\frac{1}{6}[/tex] of 2 yards is 1 foot.
Shane bought an 18 pound bag of dog food. He feeds his dog pound of dog food 5/3 for each meal. If Shane feeds his dog twice a day every day, how many days will the 18 pound bag of dog food last?
Answer:
18 pounds of dog food will last 3 days.
Step-by-step explanation:
We know that he has 18 pound of dog food and he is giving 3 pound of food twice every day, so 3 * 2 would be 6. So we need 6 pounds of dog food is being fed every day. Since we want to find out how much dog food 18 pound bag could last, you would divide 18 by 6 so 18/6 would get you 3. So we know 18 bag of dog food will last 3 days.

Step-by-step explanation: Josie selected a number n. She divided n by 2 and then subtracted ½ from the result. She took
half of that result and then subtracted ½ to get the final result of 10. What is the value of n?
Let’s start by writing Josie’s first step as an expression. Dividing n by 2, then subtracting ½ from
the result would be (n/2) – ½. If we build on this expression with the information in Josie’s
second step, we get ½((n/2) – ½) – ½. Knowing the final result is 10, we can set up the equation
below, and solve for n as follows:
½((n/2) – ½) – ½ = 10
½(n/2) – ¼ - ½ = 10 (using the distributive property)
¼n – ¼ - ½ = 10 (multiplying to eliminate the parentheses)
¼n – ¾ = 10 (combining like terms)
¼n = 10¾ (adding ¾ to both sides of the equation)
n = 43 (dividing both sides of the equation by ¼)
y - 3x = 21

Step-by-step explanation:
y-3x=21
y-3x+3x=21+3x
y=3x+21
x-5y=-35
x-5(3x+21)=-35
x-15x-105=-35
-14x-105=-35
-14x-105+105=-35+105
-14x=70
x=-5
y-3(-5)=21
y+15=21
y+15-15=21-15

Which measurement is closest to the volume of the sphere in cubic inches ?
A sphere is a three-dimensional figure where the volume is given as:
The volume of a sphere = 4/3 πr³
The volume of the sphere is 3754.7 m³.
The measurement closest to the volume of the sphere is 3431.4 m³
Option B is the correct answer.
What is a sphere?It is a three-dimensional figure where the volume is given as:
The volume of a sphere = 4/3 πr³
Example:
The volume of a sphere with a radius of 2 cm is 32π/3.
We have,
The radius of the sphere = 8 m
Now,
The volume of the sphere.
= 4/3 x π x r³
= 4/3 x 22/7 x 8 x 8 x 8
= 3754.7 m³
This is closest to the 3431.4 m³
Thus,
The volume of the sphere is 3754.7 m³.
The measurement closest to the volume of the sphere is 3431.4 m³
Option B is the correct answer.
