The sum of 2 numbers is 54. Their difference is 116. What are the numbers?
Answer:
Step-by-step explanation:
first, let the numbers be x and y.
so by question we have,
x+y=54.......(I)
x-y=116......(I I)
now, solve it through elimination method,
x+y=54
x-y=116
here, y and y cancelled out and we get,
or, x+x=54+116
or, 2x=170
or, x=170/2
therefore, x=85
now put value of x in any equation. let's put in eqn (I), we get,
or, x+y=54
or,85+y=54
or, y=54-85
so, y= -31
therefore, the numbers are 85 and - 31.

A Rabbit can hop 6 feet in 2 seconds and 12 feet in 4 seconds. If the number of feet varies directly with the time the rabbit spends hopping, at what speed is the rabbit hopping? (Hint: finds the constant of variation)
2. Write a direct variation equation for problem number 1.
(Please show your work.)
Step-by-step explanation:
1. The rabbit would be hopping at 3 feet per second.
You would first:
1. Divide each sides by 2
This would result into 3 = 1.
2. Given, 6 = 2.
If we said feet (6) = x and 2 (seconds) = y,
x = y or
feet = second (6 = 2).

A local nonprofit organization is selling popcorn to raise money for hurricane relief. The organization paid $4 per bag for the popcorn and sold it for $5 per bag. What was the percent markup on each bag of popcorn?
What is the slope of the line?
Answer:
Slope is technically 1, because it implies that it's going up one and over to the right one. Also in slope-intercept form it would look like this
y = x + 1.

How do I solve that
Answer: 6.4
Step-by-step explanation:
you take help of ratio in this case.
8/x = 2.5/2
or, (2.5).(x) = (8).(2)
or, x = 16/2.5
so, x = 6.4

For BRAINILY please help I need to pass this class
Answer:
p= 40
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
p+100+40 =180
p+140=180
p = 180-140
p= 40
Answer:
The answer is 40°. W and X are congruent to each other.
Define:
Congruent: Triangles that have both the same shape and the same size.
Straight line= 180degrees
Scalene triangle: A triangle that has no equal sides.
Isosceles Triangle: a triangle that has two sides the same length.
Equilateral triangle: A triangles all three sides are congruent.

How do find a slope???? I'm so confused
Answer:
Slope =rise/run Slope = rise/run
Explanation:
Using two of the points on the line, you can find the slope of the line by finding the rise and the run. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run
Is line p || to line q? Why?
Step-by-step explanation:
yes, because the angles match. per rule of intersecting lines the angles in one side of an intersected line are the same but mirrored on the other side of the line.
since q behave exactly as p would regarding the intersecting angles, they are parallel.

If I use 1 pound of sausage for 3/4 pound of cheese how much sausage do I need if I use 1 pound of cheese
Answer:
1.33Step-by-step explanation:
3/4 = 0.75 pound
1 : 0.75 = x : 1
x = 1 * 1 : 0.75
x = 1.33
--------------check
1 : 0.75 = 1.33 : 1
1.33 = 1.33
the answer is good
Answer:
[tex]1 \frac{1}{3}lb \: sausage[/tex]
Step-by-step explanation:
What Iike to do is make it like a ratio.
So you have one pound of sausage per 3/4lb of cheese
[tex] \frac{1lb \: sausage}{( \frac{3}{4} )lb \: cheese} = \frac{sausage}{1lb \: cheese} [/tex]
Then you just make that sausage the subject of the equation by multiplying 1lb cheese to both sides of the equation, and you have your answer.
[tex]1lb \: cheese \times \frac{1lb \: sausage}{0.75 \: lb \: cheese} = sausage[/tex]
Niall poured 2.5 liters of sports drink on
each of his two bandmates' heads after a
concert. How many centiliters did he
dump all together?
Answer:
500 centiliters
Step-by-step explanation:
Using a phase is helpful for conversions. I like this one "King Henry died by drinking chocolate milk".
K- Kilo : 0.001
H- Hecta : 0.01
D- Deca : 0.1
b- base (gram, liter, meter, etc) : 1
d- deci : 10
c-centi : 100
m-milli : 1000
For every step up or down you move the decimal one place over depending on if you go up or down.
So, for 2.5L as centiliters you would move the decimal over two spots giving you 250 centiliters. You can also multiply or divide by 10 for each step taken. so for two steps you would multiply by 100, also giving you an answer of 250 centiliters. This is then multiplied by two as 250 cL was dumped twice.
