kondaur [170]

Answer:

smaller number is 10

larger number is 39

Step-by-step explanation:

a = small number

b = larger number

a + b = 49

2a = 3b - 97

substitute 49-a into second equation for b

2a = 3(49-a) - 97

2a = 147 - 3a - 97

5a = 50

a = 10

b = 39

If k = -3 what is the value of k + (2k - 10) ? A. –19 B. –7 C. 1 D. –14

gladu [14]

Answer:

Step-by-step explanation:

We have the expression $k+(2k-10)$

We want to find the value when k is -3. So, substitute -3 for k and evaluate:

$\Rightarrow (-3)+(2(-3)-10)$

Multiply:

$=-3+(-6-10)$

Subtract:

$=-3+(-16)$

Add:

$=-19$

Therefore, our answer is A.
