Answer:

-49

Step-by-step explanation:

In order to fill in the given expression, we need to know ...

f(-2) = -4
f(-3) = 5
f(-4) = 7
g(0) = -7
g(-3) = 3

Then the expression is ...

√(5 -(-4)) -(-7)² +7÷(-7)·(3) = √9 -49 +7/(-7)(3)

= 3 -49 +(-1)(3) = 3 -49 -3

= -46 -3 = -49

Mrs. Lin is sewing costumes for her grandchildren. She is making three lion costumes, one zebra costume, and two bear costumes.

stepladder [879]

Answer:

$12\frac{1}{8}\ yd$

Step-by-step explanation:

we know that

The total fabric that Mrs. Lin needs is equal to

$3(1\frac{2}{3})+2\frac{5}{8}+2(2\frac{1}{4})$

Convert mixed number to an improper fraction

$1\frac{2}{3}=1+\frac{2}{3}=\frac{5}{3}$

$2\frac{5}{8}=2+\frac{5}{8}=\frac{21}{8}$

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

substitute

$3(\frac{5}{3})+\frac{21}{8}+2(\frac{9}{4})$

$5+\frac{21}{8}+\frac{9}{2}$

$\frac{40+21+36}{8}=\frac{97}{8}\ yd$

Convert to mixed number

$\frac{97}{8}\ yd= \frac{96}{8}+\frac{1}{8}=12\frac{1}{8}\ yd$

The sum of three numbers is 26. The second number is twice the first and the third number is 6 more than the second. Find the nu

vampirchik [111]

ANSWER

$4,8,14$

EXPLANATION

Let the first number be

$x$

Then the second number will be

$2x$

and the third number is

$2x + 6$

The sum of these numbers is 26.

This implies that;

$x + 2x + (2x + 6) = 26$

Group similar terms;

$x + 2x + 2x = 26 - 6$

Simplify;

$5x = 20$

Divide both sides by 5

$x = \frac{20}{5}$

This gives us;

$x = 4$

The numbers are:

$4,8,14$
