2 answers:

5 0

Order of operations
pemdas
parentahsees
exponents
mulitply or divide
add or subtract

for parenthasees, work inside to out, left to right

so

first one is (2-6) which is equal to -4
next parenthaees is (8/4) which is 2
now we got
[5(-4)+3(2)^2]^2
exponent
2^2=4
now we got
[5(-4)+3(4)]^2
mulitply
5(-4)=-20
3(4)=12
now we got
[-20+12]^2
simplify
-20+12=-8

now we got
[-8]^2
64

Answer:

1 $\frac{7}{20}$

Step-by-step explanation:

1. Convert the mixed number to an improper fraction to match the rest of the problem (this just makes it easier for now, the answer will still be a mixed number)

-1 $\frac{4}{5}$ becomes $\frac{9}{5}$

2. Re-write the new equation. When there is a "+" in front of a set of parentheses the expression doesn't change aside from removing the plus signs.

The new equation becomes

$\frac{9}{5} - \frac{1}{4} -\frac{1}{5}$

3. Calculate. Just work out the new expression.

The answer is $\frac{27}{20}$

4. Convert to a simplified mixed decimal.

27 goes into 20 once with seven left over, making the answer 1 $\frac{7}{20}$

I need help I don’t understand this

Hatshy [7]

Answer:

Step-by-step explanation:

lets say "a" for the empty line,

for small triangle; y^2 = 2^2 + x^2

right triangle; we say a for empty line, a^2= 6^2 + x^2

and big triangle covering both triangles, 8^2 = y^2 + a^2

lets add left sides and right sides in each;

x^2 + 4 + x^2 + 36 + y^2 + a^2 = y^2 + a^2 + 64 and we can delete same things for both sides

y^2 and a^2 can be deleted and 4+36 - 64

2(x^2)=24

x^2= 12

and x will be √12

so, y^2 = x^2 + 2^2 which means y^2 = 12+4 y=16

Nick, Joey, Beki, and Carmen ran in the town's annual road race. Each person had a different jersey number {2, 13, 20, and 34} a

erastova [34]

Answer:

Beki's jersey number is 34. She last 12 minutes

Nick's jersey number is 20. He last 10 minutes

Carmen's jersey number is 2. She last 14 minutes

Joey's jersey number is 13. He last 11 minutes

Step-by-step explanation:

• The sum of the digits on Beki's jersey number is 7. Therefore, Beki's number is necessarily 34 (3+4 = 7)

• Nick's jersey number is 18 greater than Carmen's. Therefore, Nick's jersey number is 20 and Carmen's jersey number is 2 (2 + 18 = 20). If Carmen's jersey number was 13, 13+18 = 31 which is not included in the options. If it was 20, 20+18 = 38 is not included either.

• From previous items, Joey's jersey number is 13

• The runner with the lowest jersey number also ran the slowest time. Therefore, Carmen last 14 minutes

• Nick finished exactly 2 minutes faster than Beki. Therefore, Nick's time is 10 minutes and Beki's time is 12 minutes, because from the remaining options (10, 11 and 12) this is the only combination 2 minutes apart.

• From previous items, Joey's time is 11 minutes
