Mathematics

Answer:

To find the LCM you must find all factors of the numbers, and then multiply all the factors together including the ones that are not shared among the numbers.

For example,

Factors of 10: 2×5

Factors of 30: 2×3×5

LCM of 10 and 30: 2×3×5 = 30

However do note not to multiply a factor more than once if it is shared among two numbers.

Answer:

angle j = 90

angle k = 29

angle L = 61

Step-by-step explanation:

180 = 90 + (4x-19) + (5x+1)

90 = 9x - 18

108 = 9x

x = 12

big pictures are 56$ each small ones are 34$. 97 were sold at the total of 4,376. how many big and small pictures were sold

iVinArrow [24]

Answer:

The number of big pictures are 49 and number of small pictures are 48 .

Step-by-step explanation:

Let us assume that the number of big pictures are x .

Let us assume that the number of small pictures are y .

As given

Big pictures are 56$ each small ones are 34$.

97 were sold at the total of $4,376.

Equations becomes

x + y = 97

56x + 34y = 4376

Multiply x + y = 97 by 56 and subtracted from 56x + 34y = 4376 .

56x - 56x + 34y - 56y = 4376 - 5432

-22y = - 1056

22y = 1056

$y = \frac{1056}{22}$

y = 48

Put value of y in the equation x + y = 97

x + 48 =97

x = 97 - 48

x = 49

Therefore the number of big pictures are 49 and number of small pictures are 48 .

Solving the system of linear equations by graphing

RideAnS [48]

A) y = 2x -4
B) x + 2y = 12

A) -2x + y = -4 then multiplying Equation B by 2
B) 2x + 4y = 24

Adding the equations
5y = 20
y = 4
x = 4
Okay, that was solved by elimination.
If these equations were graphed, they would be two lines that would meet at the point (4, 4)
