-3x+ 5* 2x-5= -11
 -3x+10x-5=-11
(-3x=10x=7)
7x-5=-6
(+5 on each end)
7x=-6

Which of the follwing equations has a quotient with a remainder?
Reptile [31]

Answer: Choice 2) A, B, C

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

Explanation:

Use a calculator to find that,

  • 946/32 = 29.5625
  • 1157/11 = 105.1818 approximately
  • 3524/44 = 80.0909 approximately
  • 37392/82 = 456

The first three results have a decimal portion as the answer. So there is a remainder here. The remainder is the leftover bit that couldn't make another full value. Only choice D results in a whole number that isn't a decimal value, so this does not have a remainder.

As a smaller example, let's say we had 20 cookies and 3 people. If we want to divide the cookies evenly, then each person gets 20/3 = 6 full cookies and there would be 2 cookies left over (6*3 = 18 are eaten so 20-18 = 2 is left over). Notice that 20/3 = 6.67 approximately. The non-whole number decimal value indicates we have a remainder. If we had 21 cookies, then each person gets 21/3 = 7 full cookies with nothing left over, so there's no remainder here.

Segment AB with endpoints at A(2, 4) and B(2, 18) is partitioned by point P according to the ratio of 3:4. Find the coordinate o
natta225 [31]

Using proportions, it is found that the coordinates of point P are given as follows: (2,10).

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The segment is partitioned by point P according to the ratio of 3:4, hence:

P - A = \frac{3}{7}(B - A)

This proportion is applied for both coordinates, hence, for the x-coordinate:

x - 2 = \frac{3}{7}(2 - 2)

x - 2 = 0

x = 2.

For the y-coordinate:

y - 4 = \frac{3}{7}(18 - 4)

y - 4 = 6

y = 10.

Hence the coordinates are (2,10).
