Mathematics
1 answer:
VashaNatasha [74]2 years ago
4 0

Step-by-step explanation:

We make "x" the subject of formula

2x = 11 + 5

(-5 changes to +5 because it's crossing over the equal to sign =)

2x = 16

(divide both sides by the coefficient of x)

2x ÷ 2 = 16 ÷ 2

X = 8

2. x /4 + 2 = 3

(we solve the Left Hand Side first by finding the LCM)

x/4 + 2

x + 8 = 3

‐---‐------

4

(cross multiply)

x + 8 = 4(3)

x + 8 = 12

x = 12 - 8

x = 4

3. 2(x - 7) = 3x + 10

(2 multiplies the entire bracket)

2x - 14 = 3x + 10

(collect like terms)

2x - 3x = 14 + 10

-x = 24

(multiply both sides by the negative sign "-")

x = -24

Which is an equation of the line with slope –3 and passes through (2, –1)?
vodka [1.7K]

Answer:

d)  3x + y = 5

Step-by-step explanation:

The standard equation of a line with slope and a point is given by:

y = mx + b

We know that

m=-3

Putting the value of slope

y = -3x+b

To find the value of b, we will put the point in the equation

-1 = (-3)(2)+b

-1 = -6 + b

-1+6 = b

b = 5

Putting the values of b and m in standard equation

y = -3x+5

Can also be written as:

3x+y = 5

Hence,

Option d: 3x + y = 5 is the correct answer ..

Ever bought 6 pounds and 7 ounces of pomegranates 5 pounds of melon and 15 ounces of lemon what is the combined weight of the fr
DaniilM [7]

Answer:

12 pounds, 6 ounces.

Step-by-step explanation:

First, add up both the pounds. 6+5=11 . Then, add up the ounces. 7+15=22 To simplify, since ounces make up pounds, and 16 ounces are in one pound, you would do 22 divided by 16. This will end in a decimal so take the highest number of 16 that can go into 22, which is 1. Subtract 16 from 22 to get the new number of ounces. This would be 6. Then, add 1 to the number of pounds. This would be 12. The simplified/combined answer is 12 pounds and 6 ounces.
