3 0

Answer:

16

Step-by-step explanation:

First, simplify by finding the absolute values:

2|-9| - |-2|

2(9) - (2)

Then, simplify this by multiplying 2 and 9:

18 - 2

Evaluate the expression for the given values.
Igoryamba

Answer:

a is 39

b is 57

Step-by-step explanation:

you were given two different expressions to substitute.

the first one is p = 8 and d = 1/7

so we substitute into 5p - 7d

that is 5(8) - 7(1/7)

we get 40 - 1

which if we go ahead to evaluate we get 39

The second one p = 3 and d = -6

so we get 5(3) - 7(-6)

we get 15 - (-42)

if we go ahead to evaluate we get 15 + 42

two negative meeting each other gives you positive.

then it going too be 57

To decorate the bulletin board, Wanda cut a length of ribbon into 7 equal sections, with a 16.2 -inch piece of ribbon left over.
Sedaia [141]
 im assuming you need to know the length of the 7 equal bits of ribbon. the original length of ribbon - the length of ribbon left over = 7x
170.9-16.2=154.7. 154.7/7=x = 22.1
each length of ribbon was 22.1 inches long

What is -4/5+ 7/15 when you simplify ?
photoshop1234 [79]

Answer: -\frac{1}{3}

Step-by-step explanation:

When you add fractions with different denominators, you need to find the Least common denominator (LCD):

Descompose the denominators (5 and 15) into its prime factors and then choose the commons and non-commons with the highest exponents:

5=5*1\\15=3*5\\\\LCD=5*3*1=15

Divide the LCD by each original denominator of each fraction and multiply the result by each original numerator of each fraction. After this, you can add the numerators and reduce the fraction.

Then:

-\frac{4}{5}+\frac{7}{15}=\frac{-(4)(3)+7(1)}{15}=\frac{-12+7}{15}=\frac{-5}{15}=-\frac{1}{3}
