Lera25 [3.4K]3 years ago
3 0

Answer:

x = 4 ; y = 8

Step-by-step explanation:

we can use a system of two equation

x+1 = y-3

y-5 = 2x-5

we can find x in the first equation

x = y -4

we can now substitute x with this value in the second equation

y-5 = 2(y-4)-5

y = 2y-8

y = 8

we can now find x

x = 8-4 = 4

verify

2(4)-5 = 3

8-5 = 3

8-3 = 5

4 + 1 = 5

Solve the inequality 3x-1>-6x​
Ghella [55]

Answer:

x > 1/9

Step-by-step explanation:

Given that:

3x-1>-6x​

Adding 6x + 1 on both sides we get

3x-1 + 6x + 1>-6x​ + 6x +1

3x +  6x > 1

Adding both variables

9x > 1

Dividing both sides b 9 we get

9x/9 > 1/9

x > 1/9

I hope it will help you!​

Youve been asked to build a scale model of a restaurant out of bottle caps the restaurant is 20 ft tallyour scale is 2.4 cm: 1 f
Marina CMI [18]

1 bottle cap is 1.2 cm, so two caps would be 2.4 cm ( 1.2 x 2)

The scale is 2.4 cm: 1 foot, so 2 bottle caps would equal 1 foot.

The building is 20 feet tall

 20 feet x 2 caps per foot = 40 caps total.
