<span>1/2x+3y/4=5 => (1/2)x + (3/4)y = 5
1/5x+3y/2=2 => (1/5)x + (3/2)y = 2
Eliminate the fractional coefficients: Mult. the first equation by 4 and mult. the second equation by 10:
2x + 15y = 20
</span><span>Multiply the 1st equation by -1:
-</span>2x - 3y = -20
2x + 15y = 20
-------------------
12y = 0, so y = 0. Then the first equation becomes 2x + 3(0) = 20, or
x=10.
Solution is (10,0).
Answer:
The answer to this in simplest radical form is 4160 2/9.
Answer: In two similar geometric figures, the ratio of their corresponding sides is called the scale factor. To find the scale factor, locate two corresponding sides, one on each figure. Write the ratio of one length to the other to find the scale factor from one figure to the other.
Answer:
b = (20*3+11+13)/10
Step-by-step explanation:
First add the number of people on the trip
There are 3 classes
20*3 is the numbers of students since there are 20 students per class
11 teachers and 13 parents
20*3+11+13
Then divide by the number of people per boat
(20*3+11+13)/10
The number of boats needed is
b = (20*3+11+13)/10
Ans: 1205.76 units^3
Explanation:
Volume of cylinder
= base area x height
= 3.14 x 8² x 6
= 3.14 x 64 x 6
= 1205.76 units^3
In this question, I used 3.14 instead of π.
Base area = πr²
Hope it helps :), mark me brainliest please!
