-3/5 × -4/9
= 4/15
The answer is option a. 4/15
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

Because 9 times 8 is 72. Hope this helps
Answer:
397
Step-by-step explanation:
lets say there's an eqn which is y = mx + c, x is the term no. (5, 6 in the egs provided), y is the value corresponding to x (17, 21)
to find the 100th term sequence we need to find m and c. m is how much y changes when x increases by 1
in this case we can find m easily (m = 21-17 = 4)
now we have c left so just sub one of the egs given to what we have alrd found
17 = 4(5) + c
17 = 20 + c
c = - 3
so the eqn is y = 4x - 3, and we can solve for when x = 100
y = 4(100) - 3
y = 397
hope this isn't too confusing :^)
