andriy [413]

Answer:

x = 6

Explanation:

y = x - 4

26 = 4x + y

If y = y, then we can rewrite this system as this: 4x + x - 4 = 26

Then we combine like terms and add 4 on both sides to give us 5 x = 30 . Divide by 5 on both sides and we arrive at the solution: x = 6

Answer:

$6\frac{3}{4}\ ft$

Step-by-step explanation:

we know that

To find out how long is Ms.Smith’s bulletin board, multiply Mrs . Porcelli’s bulletin board by 3

$2\frac{1}{4}(3)$

but first convert mixed number to an improper fraction

$2\frac{1}{4}\ ft=2+\frac{1}{4}=\frac{9}{4}\ ft$

substitute

$\frac{9}{4}(3)=\frac{27}{4}\ ft$

convert to mixed number

$\frac{27}{4}\ ft=\frac{24}{4}+\frac{3}{4}=6\frac{3}{4}\ ft$
