A is x=7.5 and B) is x=1

sergeinik [125]2 years ago

5 0

Step-by-step explanation:

a⟩. (4x - 1)/2 = x + 7

⇛(4x - 1)/2 = (x+7)/1

By doing cross multiplication, we get

⇛1(4x - 1) = 2(x + 7)

⇛4x - 1 = 2x + 7

⇛4x - 2x = 7-1

⇛2x = 6

⇛x = 6÷2 = 6/2

∴ x = 3 Ans.

b⟩. 3x + 2 = (2x + 13)/3

⇛(3x + 2)/1 = (2x + 13)/3

⇛3(3x + 2) = 1(2x + 13)

⇛9x + 6 = 2x + 13

⇛9x - 2x = 13-6

⇛7x = 7

⇛x = 7÷7 = 7/7

∴ x = 0 = 1 Ans.

The length of 2 sides of a triangle are 12 inches and 4 inches. Which is the third side?

Westkost [7]

Answer:

Let x = the third side

In a triangle, the sum of any 2 sides must be larger than the third side.

I believe this is called the triangle inequality theorem.

We can construct 3 inequalities to obtain the range of values for the third side.

(Inequality #1) 12 + 4 > x

16 > x

(Inequality#2) 12 + x > 4

x > -8 (we can discard this ... we know all sides will be positive)

(Inequality #3) 4 + x > 12

x > 8

So when we combine these together,

8 < x < 16

X (the third side) must be a number between 8 and 16. but not including 8 and 16

If G is the number of seconds that a traffic light says green and n is the average number of cars in each lane per light cycle,

Anna007 [38]

Answer:

31.57 cars is the answer rounded to the hundredth, but since its cars you might want to put just 31 since half a car cant pass through. it depends on what your teacher wants really.

Step-by-step explanation:

70=2.1n+3.7

70-3.7=2.1n

66.3=2.1n

66.3/2.1=n

31.57=n

Homework help. Solve 4x-2=2x-10

ahrayia [7]

4x - 2 = 2x - 10

First, subtract 2x from both sides. / Your problem should look like: $4x - 2 - 2x = -10$
Second, subtract 4x - 2 - 2x to 2x - 2. / Your problem should look like: $2x - 2 = -10$
Third, add 2 to both sides. / Your problem should look like: $2x = -10 + 2$
Fourth, simplify -10 + 2 to get -8. / Your problem should look like: $2x = -8$
Fifth, divide both sides by 2. / Your problem should look like: $x = -\frac{8}{2}$
Sixth, simplify $\frac{8}{2}$ to 4. / Your problem should look like: $x = -4$

Answer: x = -4
