Brandon is running errands for his mother.

LiRa [457]

Answer:

As it is clear that adding 1/4 + 2/3 will bring 11/12. Therefore, Brandon is correct when he claims that he walks a total of 11/12 mile if he goes from his house to the library to the grocery store.

Step-by-step explanation:

As Brandon is

1/4 mile from his house to the library

2/3 mile from the library to the grocery store

Brandon claims that he walked a total of 11/12 mile if he goes from his house to the library to the grocery store

So, adding 1/4 + 2/3 would determine whether he is right or wrong.

Thus, considering the expression

$\frac{1}{4}+\frac{2}{3}$

$\mathrm{Least\:Common\:Multiplier\:of\:}4,\:3:\quad 12$

$Adjust\:Fractions\:based\:on\:the\:LCM$

$\frac{1}{4}+\frac{2}{3}=\frac{3}{12}+\frac{8}{12}$

$=\frac{3+8}{12}$

$=\frac{11}{12}$

As it is clear that adding 1/4 + 2/3 will bring 11/12. Therefore, Brandon is correct when he claims that he walks a total of 11/12 mile if he goes from his house to the library to the grocery store.

The quotient of a number, x, decreased by 4 and 7 is less than or equal to 2 or greater than or equal to 8. What are the possibl

balu736 [363]

So this is our inequality: $2\geq\frac{x-4}{7}\ \textsf{OR}\ \frac{x-4}{7}\geq 8$

Firstly, multiply both sides by 7 on both inequalities: $14\geq x-4\ \textsf{OR}\ x-4\geq 56$

Next, add 4 on both sides of both inequalities and <u>your answer will be $18\geq x\ \textsf{OR}\ x\geq 60$ </u>

In the figure below, determine the perimeter of triangle EFG

Airida [17]

Answer:

82 units

Step-by-step explanation:

From the image, we can see that the 2 triangles are similar triangles.

Thus:

BC = EF

BD = EG

CD = FG

Now, BD = 4x - 9 and EG = 2x + 15

Thus;

4x - 9 = 2x + 15

4x - 2x = 15 + 9

2x = 24

x = 24/2

x = 12

Thus, in triangle EFG where EG = 2x + 15, then EG = 2(12) + 15 = 39

Also, EF = BC = 17

FG = 26

Thus, perimeter of triangle EFG is;

P = 26 + 17 + 39

P = 82 units
