Answer:

9 weeks

Step-by-step explanation:

Divide the total pairs of shoes by how many you lose in a week and it will give you about how many weeks it'll take to get rid of all of the shoes:

35 / 3 = 11.67

Knowing your multiplication table is key for this! You will know that the best answer for this is 9 (and not 8 or 10) because...

3 x 8 = 24

3 x 9 = 27

3 x 10 = 30

Which will give you less than 10 pairs:

35 - 27 = 8

Olve for x. 3(3x - 1) + 2(3 - x) = 0 x = 3/7 x = -3/7 x = 1/3 x = -1/3

zloy xaker [14]

Answer:

x = -3/7

Step-by-step explanation:

We are given the following equation for which we have to solve for x:

$3(3x - 1) + 2(3 - x) = 0$

So we will start by expanding the equation by multiplying the common factor with the brackets to get:

$9x-3+6-2x=0$

Arranging the like terms together (variables on one side of the equation and constants on the other side) to get:

$9x-2x=3-6\\\\7x=-3\\\\x=-\frac{3}{7}$

Therefore, x = -3/7.

Emily is trying to rewrite 45 - 27 as the product of the GCF of the two numbers and

Karolina [17]

No, it won’t work. The greatest common factor between 45 and 27 is 9, but 45-27=18. So it cannot work.

What are the sizes of angles a, b, c and d?

Lilit [14]

Answer:

a = 26°

b = 48°

c = 26°

d = 106°

Step-by-step explanation:

$c + {154}^{o} = {180}^{o} \\ c = {180}^{o} - {154}^{o} \\ c = {26}^{o}$

a = c (Alternate angles)

$a = {26}^{o}$

$b = {48}^{o}$

Corresponding angles

(a + d) + b = 180° (Interior angles)

${26}^{o} + d + {48}^{o} = {180}^{o} \\ d + {74}^{o} = {180}^{o} \\ d = {180}^{o} - {74}^{o} \\ d = {106}^{o}$
