Answer:

part A: D Marina

part B: A Anna

Step-by-step explanation:

If you're not that familiar with these fractions and their equivalents, you can always compare them using their least common denominator: 24.

Joseph: 1/3 = 8/24

Anna: 1/6 = 4/24

Elvin: 3/12 = 6/24

Theo: 1/4 = 6/24

Marina: 5/8 = 15/24

Then the ordering from least-to-greatest is ...

Anna, {Elvin, Theo}, Joseph, Marina

Part A

Marina reached the greatest fraction of the goal.

Part B

Anna reached the least fraction of the goal.

The relationship between ttt and rrr is expressed by the equation 2t+3r+6=02t+3r+6=02, t, plus, 3, r, plus, 6, equals, 0. If rrr

Greeley [361]

Question:

The relationship between t and r is expressed by the equation 2t+3r+6 = 0. If r increases by 4, which of the following statements about t must be true?

Answer:

The value of t is reduced by 6 when the value of r is increased by 4

Step-by-step explanation:

Given

$2t + 3r + 6 = 0$

Required

What happens when r is increased by 4

$2t + 3r + 6 = 0$ -------- Equation 1

Subtract 2t from both sides

$2t + 3r + 6 - 2t = 0 - 2t$

$3r + 6 = - 2t$ --- Equation 2

When r is increased by 4, equation 1 becomes

$2T + 3(r+4) + 6 = 0$

Note that the increment of r also affects the value of t; hence, the new value of t is represented by T

Open bracket

$2T + 3r+12 + 6 = 0$

Rearrange

$2T + 3r+6 +12 = 0$

Substitutr -2t for 3r + 6 [From equation 2]

$2T -2t +12 = 0$

Make T the subject of formula

$2T = 2t - 12$

Divide both sides by 2

$\frac{2T}{2} = \frac{2t - 12}{2}$

$T = t - 6$

This means that the value of t is reduced by 6 when the value of r is increased by 4

3(2x + 6) - 4x = 2(5x - 2) + 6

sp2606 [1]

Answer:

x = 2

Step-by-step explanation:

$3(2x + 6) - 4x = 2(5x - 2) + 6 \\ 6x + 18 - 4x = 10x - 4 + 6 \\ 2x + 18 = 10x + 2 \\ 18 - 2 = 10x - 2x \\ 16 = 8x \\ x = \frac{16}{8} \\ \huge \: \red { \boxed{x = 2}}$
