Mr. Greg had 8 sandwiches. He gave 1/4 to Nehamiah, 1/4 to Elijah, and 1/4 to Elizabeth. How many sandwiches did Mr. Greg have l

SVEN [57.7K]

There are many ways to work this out. One way could be:

Add up:
1/4 + 1/4 + 1/4 = 3/4

Find 3/4 of 8 so;
8 / 4 = 2
2 x 3 = 6

Find what's remaining:
8 - 6 = 2

So Mr.Greg has sandwiches left.
Hope it helped :)

5x + 2y = 7

zvonat [6]

Answer:

$(\frac{5}{7},\frac{12}{7})$

Step-by-step explanation:

The given system is

$5x+2y=7$

$y=x+1$

We substitute the bottom equation into the top equation to get:

$5x+2(x+1)=7$

Expand to get:

$5x+2x+2=7$

Group similar terms:

$5x+2x=7-2$

Combine similar terms:

$7x=5$

$x=\frac{5}{7}$

Put $x=\frac{5}{7}$ into the bottom equation

$y=\frac{5}{7}+1$

$y=\frac{5+7}{7}$

$y=\frac{12}{7}$

The solution is

$(\frac{5}{7},\frac{12}{7})$
