davids bowling score is 5 less than 3 times aarons score. The sum of their scores is 215. Find the score of each student.

Answers

Answer 1

Answer: d=David's bowling score

a=Aaron's bowling score

-----------------------------------

d=3a-5

-----------------------------------

a+d=215

---------------------------

If:

a+d=215

d=215-a

---------------------------

If d=215-a

215-a=3a-5

215+5=3a+a

220=4a

a=220/4

a=55

--------------------------

If a=55,

d=215-55

d=160

---------------------------

David's bowling score was 160.

Aaron's bowling score was 55.

Start at 125 create a pattern that subtracts 6 from each number

Answers

In this question, you are asked to make a pattern start with 125 with 6 less number each pattern. Then the pattern equation would be: 125-6x where x is determined by the position of the number.

The question doesn't specify how many numbers in the pattern that needs to be written but the pattern should be like this: 125, 119, 113, 107, 101, 95, 89, 83, 77

Answers

so 2 real solutions
just write 2 factors and expand
(x-3)(x-4)=0
x^2-7x+12=0
discriminant is when you have b^2-4ac
so subsitute
ax^2+bx+c=0
a=1
b=-7
c=12
-7^2-4(1)(12)
49-48=1
discriminant=1

one real solution would be
(x-1)(x-1)=0
x^2-2x+1=0
discriminant=-2^2-4(1)(1)=4-4=0
discriminant=0

no real solutions has the discriminant less than zero
let's say that b=1 and c=20 and a=1
basically, we need a set of numbers where b^2 is less than 4acso

1^2-4(1)(20)=1-80=-79
then we subsitute
x^2+x+20=0

What are the answers to the questions? Picture Below.

Answers

See the picture for my answers.

1. The Distributive Property lets you apply an external factor inside parentheses.

2. The Commutative Property lets you swap the order of operands. 10x and -5y

3. The Associative property lets you change the association of terms with each other.

4. The commutative Property lets you swap the order of operands (12x-5y) and 10x

Step 1: Distributive Property
Step 2: Commutative Property
And I think Step 3 & 4 is Associative Property

Answers

exponential laws
$(x^(m))^(n)=x^(mn)$
$x^{(m)/(n)}=\sqrt[n]{x^(m)}$

so
(m^(2/3))^(1/2)=m^(2/3 times 1/2)=m^(2/6)=m^(1/3)= $\sqrt[3]{m^(1)}$ = $\sqrt[3]{m}$
