Answer:
69
Step-by-step explanation:
to find f(3), we'll have to substitute x with 3
therefore,
f(3) = 19 × 3 + 12
= 57 + 12
= 69

Answer: 26 cm</h3>
====================================================
Explanation:
Refer to the diagram below. The rectangle MATH has the diagonal MT that cuts the rectangle into two identical right triangles.
We then use the pythagorean theorem to find the length of the hypotenuse MT.
a^2 + b^2 = c^2
10^2 + 24^2 = c^2
100 + 576 = c^2
676 = c^2
c^2 = 676
c = sqrt(676)
c = 26
Segment MT is 26 cm long.
This applies to the other diagonal AH as well.
Answer:
A. 3 13/20
B.3.8 kg
C.Strawberries
Step-by-step explanation:
In order to solve this we just need to find the amount of strawberries he picked, and if he picked 1 2/5 less in the morning and in the morning he picked 2 1/4, we just add that up to know how much he picked in the afternoon:

So in the afternoon he picked
.
Now he picked 5 3/10 kg of tomatoes but 1.5 were rotten, we just have to withdraw the rotten from the total:

So now we know that he picked
kg of good tomatoes.
If he picked in the afternoon and the morning 5.05 kg of strawberries, he picked more strawberries than tomatoes.
2(x-5)=2x+3
2x-10=2x+3
2x=2x+13
0x=13
x=0
There are no solutions (13/0 is 0)
Well, not specific. But after 7 hour the bus will be 210mi away
