Answer:

The two integers are 23 and 12

Step-by-step explanation:

Let the two integers be f and g

Let f be the biggest and g the smallest integer

From the first statement, the sum of the two integers is 35 i.e

f + g = 35. (1)

From second statement, we were told that when the smaller integer is subtracted from twice the larger, the result is 34 i.e

2f — g = 34. (2)

Now we'll solve by elimination method as follows:

Add equation (2) and (1) together:

2f — g = 34

+ f + g = 35

3f = 69

Divide both side by the coefficient of f i.e 3

f = 69/3

f = 23

Substituting the value of f into equation(1)

f + g = 35

23 + g = 35

Collect like terms

g = 35 — 23

g = 12

The two integers are 23 and 12

kirill115 [55]

Step-by-step explanation:

13x+2=54

subtract 2 from both sides.

13x=54

divide both sides by 13

x=4.

therefore Malika spend 4 more dollars on a string than Frankie

You have to multiply 7 by 19. Which equation uses the Distributive Property to take this problem apart?
grigory [225]

Answer: Choice A

7(10+9) = 70 + 63

============================

Explanation:

when we multiply 7 by 19, we start off multiplying just 7*9 = 63 so just focus on the units or ones digit of 19 to have it multiply with 7. We have 63 as the result so we write down "3" as part of the answer, and carry the 6.

Then you move onto the tens digit. The tens digit of 19 is 1. Multiply 1 by 7 and we get 7, which adds on to the carry digit 6 to get 7+6 = 13. Therefore we'll stick a 13 in front of the 3 we got earlier to end up with the final answer 133

---------------

Using the distribution rule is much easier in my opinion

19 = 10+9

7*19 = 7*(10+9)

7*19 = 70+63

7*19 = 133

The idea is to multiply the outer 7 by each term inside the parenthesis

7*(10+9) = 7*10 + 7*9 = 70 + 63

So we multiplied the 7 by the 10 first to get 7*10 = 70

Then did the same for the 9 term as well 7*9 = 63

After those two multiplications, we add the results up: 70+63 = 133
