According to the Question
Two buses started 2400 miles apart
They pass each other and they must have together to cover = 2400 miles
Now
Using Formula :-
Distance = Speed × Time
First bus ⇒ 5 × b = 5b
Second bus ⇒ 5(b + 60)
Now put in a Equation we get :-
5b + 5(b + 60) = 2400
5b + 5b + 300 = 2400
10b + 300 = 2400
10b = 2400 - 300
10b = 2100
b = 2100 / 10
b = 210
Hence :-
One bus speed is 210 miles
Another bus speed ⇒ 210 + 60 = 270 miles
Which table contains only values that satisfy the equation
y = 0.25x + 8?
Answer:
Step-by-step explanation:
y = 0.25x + 8
(0, 8) are coordinates of y=intercept
y = 0.25 × 2 + 8 = 8.50
(2, 8.50)
The last table represnts the given equation.
The fourth table among all the options contains values that satisfy the equation y = 0.25x + 8.
An equation is a combination of two or more expressions, all equal to each other.
Let's check every table if every point in them satisfies the equation y = 0.25x + 8,
Table 1:
To check if (0, 8) satisfies the given equation,
RHS: 0.25 × 0 + 8 = 0 + 8 = 8
LHS: 8 = RHS
This point satisfies the equation.
To check if (2, 8.25) satisfies the given equation,
RHS: 0.25 × 2 + 8 = 0.50 + 8 = 8.50
LHS: 8.25 ≠ RHS
This point does not satisfy the equation.
Table 2:
To check if (0, 0) satisfies the given equation,
RHS: 0.25 × 0 + 8 = 0 + 8 = 8
LHS: 0 ≠ RHS
This point does not satisfy the equation.
Table 3:
To check if (0, 8.25) satisfies the given equation,
RHS: 0.25 × 0 + 8 = 0 + 8 = 8
LHS: 8.25 ≠ RHS
This point does not satisfy the equation.
Table 4:
To check if (0, 8) satisfies the given equation,
RHS: 0.25 × 0 + 8 = 0 + 8 = 8
LHS: 8 = RHS
This point satisfies the equation.
Similarly, all the points can be verified that they satisfy the equation.
Thus, all values in Table 4 satisfy the given equation.

The school in town is building a track around its football stadium. The principal must decide whether to build a track with 6 lanes or 7 lanes. A 6-lane track will be 28.68 feet wide, and a 7-lane track will be 28.98 feet wide. If all lanes are of equal width in each track, how much wider will the lanes be in a 6-lane track than in a 7-lane track?
Answer:
the 6 lane track will be 0.64 feet wider than the 7 lane track
Step-by-step explanation:
28.68÷6=4.78
28.98÷7=4.14
4.78-4.14=0.64
Lucas is making a wire sculpture for art class. For the sculpture, he needs to cut a wire into pleces that
are each 1/16 of a foot long. If the original wire is 3/4 of a foot long, how many pieces will Lucas have?
⟹Answer:
➧Lucas can cut the wire into 12 pieces.
Step-by-step explanation:
⟹Lets Solve!
⟹The first step is to convert [tex]\frac{3}{4}[/tex] into [tex]\frac{}{16}[/tex] !
To do this we must find what number multiplied by 4 equals 16.
16 ÷ 4 = 4
⟹Now we know our multiplier is 4. So lets multiply the numerator and denominator by 4.
[tex]\frac{3}{4} * \frac{4}{4} = \frac{12}{16}[/tex]
[tex]\frac{12}{16}[/tex]
⟹Next we just divide [tex]\frac{12}{16}[/tex] by [tex]\frac{1}{16}[/tex].
[tex]\frac{12}{16}[/tex] ÷ [tex]\frac{1}{16}[/tex] = 12
➧Lucas can cut the wire into 12 pieces.
Woohoo! Brainliest appreciated! Hope I helped!
Based on the original length of the wire and the length Lucas requires, he will have 12 pieces.
The wire is 3/4 feet long and each piece required will be 1/16 feet.
The number of pieces in total is:
= Length of wire / Length of pieces
Solving gives:
= 3/4 ÷ 1/16
= 3/4 × 16/1
= 48/4
= 12 pieces
In conclusion, Lucas will have 12 pieces.

Here are 36 carpenters on a construction crew. On a certain day, 29 carpenters were present. Which proportion can be used to determine the percent of carpenters that were present?
Answer:
80.6%
Step-by-step explanation:
Given that :
Total construction crew = 36
Number present in a certain day = 29
Percentage present on that day :
(Number present / total number) * 100%
(29 / 36) * 100%
0.8055555 * 100%
80.555%
= 80.6%

Answer:
The answer is the first option x(x-4)(x-1)/2(x+4).
Step-by-step explanation:
because when you simplify after multiplying the denominator is 2x+8 when you simplify that its 2(x+4) and for the numerator after multiplying you get x^3−5x^2+4x when you simply that you get x(x-4)(x-1). Answer would be x(x-4)(x-1)/2(x+4).
In this figure of a protractor , which angle is a right angle?
2(x + 0.7) = 6(x – 0.8) well what i got for this is 2x + 1.4 = 6x - 4.8 -2 -2 1.4 = 4x - 4.8 +4.8 +4.8 so i do i finish this equation i need the answer how do i finish this Equation?
Answer:
1.55
Step-by-step explanation:
[tex]2(x + 0.7) = 6(x – 0.8)[/tex]
Using the distributive property of addition over multiplication we get
[tex]2x+1.4=6x-4.8[/tex]
Take the like terms to one side and change their signs accordingly
[tex]1.4+4.8=6x-2x[/tex]
[tex]\Rightarrow 6.2=4x[/tex]
[tex]\Rightarrow x=\dfrac{6.2}{4}[/tex]
[tex]\Rightarrow x=1.55[/tex]
The value of [tex]x[/tex] is 1.55.
In order to make sure this value is correct we can substitute the value of x in the equation
[tex]2(1.55+0.7)=6(1.55-0.8)\\\Rightarrow 2\times 2.25=6\times 0.75\\\Rightarrow 4.5=4.5[/tex]
So, both sides are equal hence the value of [tex]x [/tex]is 1.55.

Density is also the slope of the relationship between mass and volume. If the density 7.2 g /mL, what is the slope?
Answer:
The slope for the substance = 7.2 g/mL
Step-by-step explanation:
Given that the density is also the slope relationship between mass and volume and that the density is equal to 7.2 g/mL, therefore, the slope of the equation of the line relating mass to volume is also equal to 7.2 g/mL
The density = Mass/Volume = 7.2 g/mL
The slope of mass volume relationship = (The change in mass)/(The equal change in volume)
Whereby the change is from the zero state, we have;
The slope of mass volume relationship = (Mass - 0))/(Volume - 0) = Mass/Volume
Therefore;
The value of the slope of the substance = The value of the density of the substance = 7.2 g/mL
The value of the slope for the substance = 7.2 g/mL.

Write the equation of the parabola in vertex form.
vertex (3,4), point (2,-2)
Answer:
y = - 6(x - 3)² + 4Step-by-step explanation:
The vertex form of the equation of the parabola with vertex (h, k) is:
y = a(x - h)² + k
So the equation of the parabola with vertex (3, 4):
y = a(x - 3)² + 4
The parabola passes through point (2, -2) so if x=2 then y=-2
- 2 = a(2 - 3)² + 4
- 2 -4 = a(-1)² + 4 -4
- 6 = a
So, the equation written in vertex form of a parabola with a vertex of (5, 7) that passes through (2, -2):
y = - 6(x - 3)² + 4
Factor the expression.

A group of friends equally split the dinner bill shown. If each person paid $16, how many friends paid?
Answer:
4
Step-by-step explanation:
Wait... this doesn’t make sense because it doesn’t tell you if there was tax, how many friends there were, or tips.
Answer:
16/y = x
Step-by-step explanation:
You cannot solve for the question yet. However, you can create an equation!
we know that each person paid 16 dollars.
We don’t know how much the bill was or how many people were there.
So out equation looks like;
z/y = x
or
z * x = y
z = how much each person paid.
y = how much each person paid.
x = how many people paid.
Substitute with what we know.
16/y = x
16 * x = y
Now you will be able to substitute for either x or y to find either answer.
