Answer:
[tex]\frac{5}{14}[/tex]
Step-by-step explanation:
It's important to note here that fractions are just another way of representing division.
Therefore, [tex]\frac{\frac{1}{4}}{\frac{7}{10}}[/tex] is the same thing as [tex]\frac{1}{4} \div \frac{7}{10}[/tex].
To divide two fractions, we multiply by the reciprocal.
[tex]\frac{1}{4} \cdot \frac{10}{7}[/tex]
We can now multiply the numerators and denominators.
[tex]1\cdot 10 = 10\\7 \cdot 4 = 28\\\\\frac{10}{28}[/tex]
We can simplify this fraction by dividing both the numerator and denominator by 2.
[tex]10\div 2 = 5\\28 \div 2 = 14[/tex]
So, [tex]\frac{5}{14}[/tex].
Hope this helped!
x=40 and y=70 find value of z
Answer:
X=40 and y=70 if you add z you get 110 but I'm not really sure about this answer so you can also subtract it you get 30
Step-by-step explanation:
If 2x-3y+5-(x-3y)=11-2x, what is the value of x?
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
[tex]2x-3y+5-\left(x-3y\right)=11-2x[/tex]
Remove brackets and flip the sign in the brackets:
[tex]2x-3y+5-x+3y=11-2x[/tex]
Group the similar terms together:
[tex]-3y+3y+2x-x+5=11-2x[/tex]
Add/subtract the terms:
[tex]x+5=11-2x[/tex]
Subtract 5 from both sides:
[tex]x+5-5=11-2x-5[/tex]
[tex]x=-2x+6[/tex]
Add 2x to both sides:
[tex]x+2x=-2x+6+2x[/tex]
[tex]3x=6[/tex]
Divide both sides by 3:
[tex]\frac{3x}{3}=\frac{6}{3}[/tex]
[tex]x=2[/tex]

4 x 6 - 4
4 x (6-4)
Answer:
24-4= 20
4×2= 8
Step-by-step explanation:
4 by 6 is 24 minus 4
6-4 is 2 by 4 is 8
Answer:
no
Step-by-step explaination:
first equation: well, you first do 4x6, witch is 24, then you subtract the 4, witch is: 4x6=24, 24-4= 20
second equation: since 6-4 are in bracets, you do that sum first, witch is equal to 2, then you multiply that result by 4, witch is 8, conclusion: (6-4)=2, 2x4=8
answere: 20 deos not equal to 8, so, no.
(sorry if my explaination is bad, im new here)
The scale drawing of a rectangular city park measures 10.0 cm by 5.0 cm. The scale of the drawing is 1.0 cm = 4.5 m. What is the area, in square meters, of the park?
Answer:
2250m^2Step-by-step explanation:
In this exercise, we are going to be converting from cm to m, since we are asked to provide our answers in meters
Given that the scale is 1.0 cm = 4.5 m
let us convert the 10cm to the actual length
1 cm------4.5m
10 cm------x
x= 4.5*10
x= 45m
Also for the 5 cm
1 cm------4.5m
5 cm------x
x= 5*10
x= 50m
Hence the area of the actual rectangular park is
45*50= 2250m^2

Find the distance between (-8,-2) and (6,-1)
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ \sqrt{197} \: \: units}}}}}[/tex]
Step-by-step explanation:
Let the points be A and B
Let A ( -8 , -2 ) be ( x₁ , y₁ ) and B ( 6 , - 1 ) be ( x₂ , y₂ )
Finding the distance between these points
[tex] \boxed{ \sf{distance = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } }}[/tex]
[tex] \dashrightarrow{ \sf{ \sqrt{ {(6 - ( - 8))}^{2} + {( - 1 - ( - 2))}^{2} } }}[/tex]
[tex] \dashrightarrow{ \sf{ \sqrt{ {(6 + 8)}^{2} + {( - 1 + 2)}^{2} } }}[/tex]
[tex] \dashrightarrow{ \sf{ \sqrt{ {(14)}^{2} + {(1)}^{2} } }}[/tex]
[tex] \dashrightarrow{ \sf{ \sqrt{196 + 1}}} [/tex]
[tex] \dashrightarrow{ \boxed{ \sf{ \sqrt{197 \:} \: units}}} [/tex]

So, therefore, X = 5
Answer:
x=5
Step-by-step explanation:
7+x=12
Minus both sides by 7
7+x=12
-7 -7
=0 =5
drop the x
x=5

If -2 and 3 are zeroes of quadratic polynomial xsquare + (a+1)x+b then find the value of and b
Answer:
a = - 2, b = - 6
Step-by-step explanation:
Substitute the values of the zeros into the polynomial and equate to zero.
x² +(a + 1)x + b
x = - 2 → (- 2)² - 2(a + 1) + b = 0 , that is
4 - 2a - 2 + b = 0
2 - 2a + b = 0 ( subtract 2 from both sides )
- 2a + b = - 2 → (1)
x = 3 → 3² + 3(a + 1) + b = 0, that is
9 + 3a + 3 + b = 0
12 + 3a + b = 0 ( subtract 12 from both sides )
3a + b = - 12 → (2)
Subtract (1) from (2) term by term to eliminate b
5a = - 10 ( divide both sides by 5 )
a = - 2
Substitute a = - 2 into either of the 2 equations and evaluate for b
Substituting into (2)
3(- 2) + b = - 12
- 6 + b = - 12 ( add 6 to both sides )
b = - 6
Thus a = - 2 and b = - 6

What happens to the copy when it is created with a scale factor greater than 1? Less than
1? Exactly 1?
Answer:
When a figure is scaled by a scale factor greater than 1, the copy is larger than the original. When the scale factor is less than 1, the copy is smaller. This means that triangles and are scaled copies of each other.

It would be the last bubble, 4/6
hope I helped ya
what is 143x+4=12 please help
help meeeeeeeeeeeeeeeee plz
Answer:
a 10.21
Step-by-step explanation:
because 20 - 9.79 = 10.21
Answer:
the ans in the third one,
10.21, it shows the change
Step-by-step explanation:
20.00=c+9.79
so Pablo has 20.00 and he has to use 9.79
so if u add the change and the money he has to use, will be the money he has right now
so c = the change
so...
20.00=c+9.79
20.00-9.79=c
(so if u subtract the amount of money pablo has to pay from the money he has will be the change he will get)
10.21=c
If he watches all the movies that are 1 3/4 hours long how long will it take
