Answer:
You have to multiply the numbers diagonally not vertically.
So
10x = 7(350)
10x = 2450
x = 245
9514 1404 393
Answer:
different sides of the equation were multiplied by different numbersx = 245Step-by-step explanation:
There is a method of solving proportions that is called "cross multiply" or "cross multiplication". For a proportion like this it looks like each numerator is multiplied by the opposite denominator. In this problem, the result would be ...
7(350) = (10)x
While "cross multiplication" is a description of the appearance of what is happening, what is really happening is that both sides of the equation are being multiplied by the same value: the product of the denominators. This is in accordance with the multiplication property of equality, which requires you multiply both sides of the equation by the same value.
__
The error that was made in this problem is that each numerator was multiplied by its own denominator. Effectively, that multiplied the left side of the equation by 10² = 100, and the right side of the equation by 350² = 122500. This is in direct violation of the multiplication property of equality, so guarantees the value found for x will be wrong.
__
While "cross multiply" is an instruction often given for solving proportions, it causes an extra step to be needed in solving a proportion like this one. All that is really needed is to multiply both sides of the equation by the denominator under the variable. Here, that means multiplying both sides of the equation by 350.
Correct solution
[tex]\dfrac{7}{10}=\dfrac{x}{350}\\\\350\cdot\dfrac{7}{10}=350\cdot\dfrac{x}{350}\\\\\\35\cdot 7=\boxed{x=245}[/tex]

Of 42 cities, 5 have a lake and 29 have a river running through them what fraction of these 42 cities have a lake or river running through them
Answer: 17/21
Step-by-step explanation:
Number of cities = 42
Fraction of cities that has lake = 5/42
Fraction of cities that have rivers = 29/42
The fraction of these 42 cities that have a lake or river running through them will then be:
= 5/42 + 29/42
= 34/42
= 17/21

it makes the most sense
A set is a mathematical model for a collection of items. The typical value is greater in Set A, while the spread is greater in Set B.
What is a set?A set is a mathematical model for a collection of items; it comprises elements or members, which may be any mathematical object: numbers, symbols, points in space, lines, other geometrical structures, variables, or even other sets.
In two of the given sets, the typical value is represented by a triangle, therefore, the typical value in Set A is 7.1..., while the typical value in Set B is 6.
Hence, the typical value is greater in Set A, while the spread is greater in Set B.

A shop is having a sale all items are reduced work out the sale price of an item normally priced at £60
Question:
A shop is having a sales all items are reduced by 25%. Work out the sale price of an item normally priced at £60?
Answer:
The new price is £45
Step-by-step explanation:
Given
[tex]Sales\ price = \pounds 60[/tex]
[tex]Rate = 25\%[/tex]
First, calculate the reduction
[tex]Reduction = Rate * Sales\ price[/tex]
[tex]Reduction = 25\% * \pounds 60[/tex]
[tex]Reduction = \pounds 15[/tex]
The new price is:
[tex]New = Sales\ price - Reduction[/tex]
[tex]New = \pounds 60 - \pounds 15[/tex]

Raju bought an old car for Rs.125000 and spent Rs.25000 on its repair . He sold the car for Rs.200000 . Find his gain or loss percent .
Answer: [tex]33.33\%[/tex]
Step-by-step explanation:
Given
Raju buy an old car for [tex]Rs\ 1,25,000[/tex]
He spent [tex]Rs\ 25000[/tex] on its repair
The selling price of the car [tex]Rs\ 2,00,000[/tex]

If P is the incenter of triangle JKL, find PJ.
Answer:
PJ = 41.34
Step-by-step explanation:
P is incenter, three angles bisector meet
∠MJP ≅ ∠OJP
PM = PN = PO = 22 (radius: property of incenter)
∠JPM = 90 - ∠MJP = 90 - OJP = ∠JPO
ΔJPM ≅ ΔJPO (ASA) or (SAS)
LM = JO
2x + 3 = 5x - 45
3x = 48
x = 16
JM = 35
PJ = √35²+22² = √1709 = 41.34
The value of PJ in triangle KJL is 41.32 units.
What is incenter?The point formed at the intersection of the three angle bisectors of a triangle; also the centre of the incircle.
Given that, P is incenter of the triangle KJL,
Considering the triangles ΔMJP and ΔOJP
PM = PO (property of incenter)
∠ JMP ≅ ∠ JOP
JP is common segment.
ΔJPM ≅ ΔJPO (by SAS rule)
JM = JO (CPCTC)
2x + 3 = 5x - 45
3x = 48
x = 16
JM = 35
Using the Pythagoras theorem,
PJ² = PM²+JM²
PJ = √35²+22² = √1709 = 41.34
Hence, The value of PJ in triangle KJL is 41.32 units.

The points M(-10, 3) and P(-4,-8) are graphed on the coordinate plane. To the nearest
tenth of a unit, what is the distance between points Mand P? Round to the nearest
tenth.
Given:
The two points are M(-10, 3) and P(-4,-8).
To find:
The distance between the points M and P.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, the distance between the given points is
[tex]MP=\sqrt{(-4-(-10))^2+(-8-3)^2}[/tex]
[tex]MP=\sqrt{(-4+10)^2+(-11)^2}[/tex]
[tex]MP=\sqrt{(6)^2+(-11)^2}[/tex]
[tex]MP=\sqrt{36+121}[/tex]
On further simplification, we get
[tex]MP=\sqrt{157}[/tex]
[tex]MP=12.529964[/tex]
[tex]MP\approx 12.5[/tex]
Therefore, the distance between the given points M and P is 12.5 units.

12/18 In simplest form
Answer:
Find the gcf, greatest common factor, of 12 and 18 and solve
Step-by-step explanation:
12: 1, 2, 3, 4, 6, 12
18: 1, 2, 3, 6, 9, 18
The gcf is 6, so divide the numerator and denominator by 6.
12 / 6 = 2
18 / 6 = 3
Therefore, 12/18, when relatively prime, is 2/3
