Mrs Granger is writing problems for a test about subtracting fractions.Help her write two different subtraction problems that use only odd numbers for numerators and each have a difference of 3/4
1.
The first subtraction problem that will use only odd numbers as numerators and have a difference of 3/4 is 1 - ¹/₄
The first subtraction problem that will use only odd numbers as numerators and have a difference of 3/4 is
1 - ¹/₄ = ¹/₁ - ¹/₄
taking the L.C.M which is 4, we have
= (4 - 1)/4
= 3/4
So, the first subtraction problem is 1 - ¹/₄
2.
The second subtraction problem that will use only odd numbers as numerators and have a difference of 3/4 is 2¹/₂ - 1³/₄
The second subtraction problem that will use only odd numbers as numerators and have a difference of 3/4 is
2¹/₂ - 1³/₄ = ⁵/₂ - ⁷/₄
taking the L.C.M which is 4, we have
= (10 - 7)/4
= 3/4
So, the second subtraction problem is 2¹/₂ - 1³/₄

Step-by-step explanation:
Hii, so I'm assuming your equation is equal to 0-->
x²+_x+36 =0
this could go many ways..
x²+12x+36 =0
which factor to (x+6)(x+6)
x²+15x+36 =0
which factor to (x+12)(x+3)
x²+13x+36 =0
which factor to (x+9)(x+4)
If I had to choose a answer.. I would go with the 1st option x²+12x+36 =0

1) Which multiplication expression is equivalent to
-8 + (-8) + (-8) + (-8)?
Answer:
-8 x 4
Step-by-step explanation:
Multiplication is really just repeated addition. In multiplication, the 2 terms are the number being added and the number of times it is added. In this case, the number being added is -8 and it is being added 4 times. Therefore, the multiplication expression must be -8 x 4.

A model village is built to scale. It has a scale of 1 : 23. A road has a real-life length of 1.61 km. What is the length of the road in the model village in m?
Answer:
We need to find how much more or less the ratio becomes
1.61 / 23 = 0.07
we multiply 0.07 with 1 to make the ratio even and get your answer
1 x 0.07 = 0.07 on the map

Sue ran 7 miles more than Jill last week. Sue ran 11 miles. Which equation will tell you how many miles Jill ran?
A)
x + 7 = 11
B)
X-7 = 11
9
C)
x + 7 = -11
D)
X - 7 = -1
Answer:
The number of miles Jill ran is the number of miles Sue ran (11) minus the number of miles Sue ran more than Jill (7).
So far, x=11-7.
Reorder the equation. Add 7 to both sides.
x + 7 = 11.
So, the correct equation is A.
:)
A) x + 7 = 11
Jill runs x amount of miles and Sue runs x miles plus 7 miles.

need help now please i will give 25 points
Answer:
Answer is letter B
if im wrong i'm sorry that my opinion
Answer:
B) y = -x + 2
Step-by-step explanation:
First, we pick 2 points that are on the line:
(0, 2) and (1, 1)
Next, we find the slope (m):
m = (y2 - y1)/(x2 - x1)
m = (1 - 2)/(1 - 0)
m = (-1)/1
m = -1
Then, we do point-slope formula to create the equation:
y - y1 = m(x - x1)
y - 2 = -1(x - 0)
y - 2 = -x
y = -x + 2
Juwan went on a bike ride of 36 miles. He realized that if he had gone 15 mph faster, he would have arrived
10 hours sooner. How fast did he actually ride?
Step-by-step explanation:
Distance = (Rate)(Time) So, Time = (Distance)/(Rate)
Time at slower speed = Time at faster speed + 3
36/x = 36/(x+6) + 3
Multiply the equation by the LCD, x(x+6) to obtain:
36(x+6) = 36x + 3x(x+6)
36x + 216 = 36x + 3x2 + 18x
3x2 + 18x - 216 = 0
x2 + 6x - 72 = 0
(x + 12)(x - 6) = 0
x = -12 or x = 6
Since x can't be negative, x = 6 mph

(5,65) (7,71) slope
Answer:
3
Step-by-step explanation:
The slope formula is m=y2-y1/x2-x1
y2 is 71
y1 is 65
x2 is 7
x1 is 5
71-65 is 6
7-5 is 2
So the slope looks like this:
6/2
Simplify:
Which is 3
