Answer:
200/50=h
h=number of hours
Step-by-step explanation:
Maddie drove 200 miles at a speed of 50 miles per hour.
As we know
speed = miles/hours
and to calculate we use the formula
Hour = miles/speed
So the equation that helps to find the number of hours she was driving =
h = 200/50
Equation will be h = 200/50
Answer: StartFraction 50 miles Over 1 hour EndFraction = StartFraction 200 miles Over question mark hours EndFraction
Step-by-step explanation:
For constant speed, miles and hours are proportional. One possible equation is ...
_____
I personally like to put the unknown in the numerator, so the equation can be solved in one step. The equation above requires two steps: one to cross-multiply, and one to divide by 50.
I might write the equation as ...
(? hours)/(200 mi) = (1 hour)/(50 mi) . . . . multiply by 200 mi to solve
Another way to write the equation is matching the ratios of times to corresponding miles:
(? hours)/(1 hour) = (200 mi)/(50 mi)
This only requires simplification to solve it: ? = 4.
So it would be A.

How to check 20p+75=35p+30
[tex]20p+75=35p+30[/tex]
Step 1: Subtract [tex]20p[/tex] from both [tex]p[/tex] sides
[tex]\:\:\:\:20p+75=35p+30\\-20\:\:\:\:\:\:\:\:\:\:\:\:-20[/tex]
20 - 20 = 0, so it is canceled out. 35 - 20 = 15, don't forget the [tex]p[/tex]!
[tex]75=15p+30[/tex]
Step 2: Subtract 30 from both sides
[tex]\:\:\:\:75=15p+30\\-30\:\:\:\:\:\:\:\:\:\:\:\:-30[/tex]
30 - 30 = 0, so it is canceled out. 75 - 30 = 45.
[tex]45=15p[/tex]
Step 3: Divide both sides by 15
[tex]\frac{45}{15} =\frac{15p}{15}[/tex]
15 ÷ 15 cancels out. 45 ÷ 15 = 3.

What is the rate of change over the interval [-1,2] for f(x)= 4x +1
Answer:
4
Step-by-step explanation:
To find the average rate of change, we have to plug in the difference between the intervals with this equation: f(b) - (fa) / x₂ - x₁
Let f(a) = f(-1) = 4(-1) + 1
f(b) = f(2) = 4(2) + 1
x₂ = 2
x₁ = -1
[4(2) + 1 - (4(-1) + 1)] / [2 - (-1)]
[8 + 1 + 4 - 1] / [3]
12 / 3 = 4
Please help with this math problem! Will give brainliest! :)
Answer:
9
Step-by-step explanation:
All triangles (3 sided polygons) have angles added up to 180, so we can do the following:
(7x-1) + (7x+8) + (5x+2) = 180° - equation
7x-1 + 7x+8 + 5x+2 = 180° - "distribute"
19x - 1 + 8 + 2 = 180° - combine the x terms
19x + 9 = 180° - combine the integer terms
19x = 171 - subtract 9 form both sides
x = 9 - divide both sides by 19

In a class, 4/7 of the total number of students are boys. If 2/5 of the boys or 8 boys are wearing spectacles, calculate the number of girls in the class.
Answer:
15
Step-by-step explanation:
let total num of boys be X.
then,2/5 of X = 8
2 ×x = 40
X = 20
Now, let the total num of students be y,then we get,
4/7 of y = 20
4 × y = 140
y = 35
similarly, total num of girls = total num of students - total num of boys
= 35 - 20
= 15 ans

Please help! Geometry practice was lines cut by a transversal. What is the value of X?
Answer:
x = 70
Step-by-step explanation:
1. First, we need to know that the angle with 45 degrees and the angle with (2x-5) degrees are same-side interior angles, meaning they add up to 180 degrees. The equation of this can be written as so: [tex]2x-5+45= 180[/tex]
2. (Solving)
Step 1: Combine like terms.
[tex](2x) +(-5+45) = 180[/tex] [tex]2x + 40 = 180[/tex]Step 2: Subtract 40 from both sides.
[tex]2x + 40 - 40 = 180 - 40[/tex] [tex]2x = 140[/tex]Step 3: Divide both sides by 2.
[tex]\frac{2x}{2} = \frac{140}{2}[/tex] [tex]x = 70[/tex]Step 4: Check if solution is correct.
[tex]2(70) - 5 + 45 = 180[/tex] [tex]140 - 5 + 45 = 180[/tex] [tex]135 + 45 = 180[/tex] [tex]180 = 180[/tex]Therefore, x = 70.

HELP PLEASE QUICK I BEG I SUCK AT MATH
Answer:
y = 3/8x + 3
Step-by-step explanation:
Parallel lines have the same slope. In given equation, y = 3/8x + 5, the slope, m = 3/8. Therefore, the other line must also have the same slope.
Using the slope, m = 3/8, and the given point, (16, 9), substitute these values into the slope-intercept form:
y = mx + b
9 = 3/8(16) + b
9 = 6 + b
9 - 6 = 6 - 6 + b
3 = b (this is the y-intercept).
Now that we have our slope, m = 3/8, and the y-intercept, b = 3:
The equation of the line parallel to y = 3/8x + 5 is:
y = 3/8x + 3

10. Do the multiple of 2, 3, and 4. Then find the LEAST common number that all three numbers have in common. (Answer: 12)
STEPS ON HOW TO SOLVE:
Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 3, 4, and 6. Write this prime number(2) on the left of the given numbers(3, 4, and 6), separated as per the ladder arrangement.
Step 2: If any of the given numbers (3, 4, 6) is a multiple of 2, divide it by 2 and write the quotient below it. Bring down any number that is not divisible by the prime number.
Step 3: Continue the steps until only 1s are left in the last row.
The LCM of 3, 4, and 6 is the product of all prime numbers on the left, i.e. LCM (3, 4, 6) by division method = 2 × 2 × 3 = 12.

The stock market drops 18 points.
or stocks, one point equals one dollar. So when you hear that a stock has lost or gained X number of points, it is the same as saying the stock has lost or gained X number of dollars.
Using points to describe share price gains, or declines, is generally done to describe short-term results, such as for the day or week.
Although one point always equals one dollar, the percentage value of a one-point movement can be different for two companies. Points refer only to the dollar amount that has changed, not the percentage. Two stocks can lose the same number of points but very different percentages.
