Answer:

x = 7 ; y = 9

Step-by-step explanation:

Given the system of equation :

y = 2x - 5 - - - (1)

-x + y = 2 ___(2)

From (1)

y = 2x - 5

Put y = 2x - 5 into (2)

-x + 2x - 5 = 2

-x + 2x = 2 + 5

x = 7

We can then solve for y;

Substituting x = 7 into. Equation (1)

y = 2x - 5

y = 2(7) - 5

y = 14 - 5

y = 9

Hence ;

x = 7 ; y = 9

To answer this question you would need to solve this inequality. The first step would be to combine all three terms on the left-hand side of the greater than symbol. By doing this you would have 50w > 250. To solve this inequality divide both sides by 50. The answer is w > 5. In words, this means the number of walnuts per spoonful is greater than five.

Write one digit on each side of 23 to make a four digit multiple of 72. How many different solutions does this problem have?
user100 [1]

Answer:

This problem has two possible solutions.

2232

7236

Step-by-step explanation:

To be divisible by 72, a number has:

To be divisible by both 8 and 9 at the same time.

It is divisible by 8 if it's last two digits are divisible by 4.

It is divisible by 9 it the sum of it's digits is a number divisible by 9.

a23b

3b must be divisible by 4. In the thirties, the numbers that are divisible by 4 are 32 and 36. So b = 2 or b = 6.

a232

2 + 3 + 2 = 7

The higest possible value of a is 9 and the lowest is 1.

Between 8 and 16, only 9 is divisible by 9. So a = 2.

a = 2, b = 2 is one of the solutions.

a236

2 + 3 + 6 = 11

The higest possible value of a is 9 and the lowest is 1.

Between 12 and 20, only 18 is divisible by 9. So we need a = 7

Which Value of t makes the following true -16+t<-32
ololo11 [35]
T would equal anything lower than -17 (basically, -18, -19, -20, etc). This is because -16 + -17 = -33.
