Fifteen more than half a number is 9?

1 answer:

6 0

That in algebraic form would be $\frac{1}{2}n + 15 = 9$

Subtract 15 to both sids and you get
$\frac{1}{2}n = -6$

Multiply 2 on both sides and you get
n = -12

Misty has several pieces of construction paper that each measure 4 inches long and 9 inches wide. She needs to create the smalle

solniwko [45]

We are given that the dimensions are 4 in x 9 in. To get the smallest possible square, first let us find for the LCM of 4 and 9.

4 = 0, 4, 8, 12, 16, 20, 24, 28, 32, 36

9 = 0, 9, 18, 27, 36

We can actually see that 36 is the least common multiple.

Therefore the smallest possible square has a dimension of:

3/6 power of two + 7 × 4 − 5

prisoha [69]

Answer:

$23\frac{1}{4}$

Step-by-step explanation:

$(\frac{3}{6})^2+7*4-5$

Use PEMDAS:

Solve the Exponent.

$(\frac{a}{b})^n=\frac{a^n}{b^n}$

$(\frac{3}{6})^2=\frac{9}{36}=\frac{1}{4}$

Multiply:

$\frac{1}{4}+7*4-5\\\\\frac{1}{4}+28-5$

Add and Subtract:

$\frac{1}{4}+28-5\\\\28\frac{1}{4}-5\\\\ \boxed{23\frac{1}{4}}$
