How do u do this step by step

Answers

Answer 1

Answer: You need to use PEMDAS or the Order of Operation. P is parentheses, E is exponents, M is multiplication, D is division, A is addition, and S is subtraction. 8+5 is 13. There are No exponents or multiplication. Divide 13 by 1 and you get 13. So far, you have 1 + 13 - 3 - 13 + 4. If you do the addition you get 18 - 3 -13. 18 - 3 is 15. 15 - 13 is 2. Your answer is 2.

Answers

Answer:

1 - D

2 - D

3 - B

4 - B

Step-by-step explanation:

Ques 1: Let the temperature in Tampa be denoted by X°F

It is given that the temperature never reaches below 40°F

The inequality representing the given situation is $X\geq 40$ .

So, D is correct.

Ques 2: Let the times Sarah read = S and the times Joel read = J.

It is given that Sarah read 3 more times than that of Joel and she read 9 times.

So, the equation becomes, $S=J+3$ i.e. $9=J+3$

So, option D is correct.

Ques 3: Since, 1 inch = 2.54 centimeters

So, 4.5 inch = $(2.54)/(1)* 4.5$ = 11.4 centimeters

Thus, option B is correct.

Ques 4: As we have that, $(2)/(5)=(6)/(15)=(18)/(45)$

So, the ratio not equivalent to others is $(12)/(25)$ .

So, option B is correct.

How to solve 3+5 (c+3)=-17

Answers

3 + 5(c + 3) = -17

First, subtract 3 from both sides. / Your problem should look like: $5(c + 3) = -17 - 3$
Second, simplify -17 - 3 to get -20. / Your problem should look like: $5(c + 3) = -20$
Third, divide both sides by 5. / Your problem should look like: $c + 3 = -(20)/(5)$
Fourth, simplify $(20)/(5)$ to 4. / Your problem should look like: $c + 3 = -4$
Fifth, subtract 3 from both sides. / Your problem should look like: $c = -4 - 3$
Sixth, simplify -4 - 3 to get -7. / Your problem should look like: $c = -7$

Answer: c = -7

3+5(c+3)=−17

3+(5)(c)+(5)(3)=−17(Distribute)

3+5c+15=−17

(5c)+(3+15)=−17(Combine Like Terms)

5c+18=−17

Subtract 18 from both sides.

5c+18−18=−17−18

5c=−35

Divide both sides by 5.

5c/5=−35/5

c=−7

Solve -1 4/5 x= 9.
A) 5
B) 1/5
C) -5
D) -1/5

Answers

Answer:

C) -5

Step-by-step explanation:

-1 4/5 x= 9.

Change the left side to an improper fraction

(5*1+4)/5 = 9/5

-9/5 x =9

Multiply each side by -5/9 to isolate x

-5/9 * 9/5x = 9 * (-5/9)

x = -5

Answer:

C) -5

Step-by-step explanation:

-1 4/5 x= 9.

Change the left side to an improper fraction

(5*1+4)/5 = 9/5

-9/5 x =9

Multiply each side by -5/9 to isolate x

-5/9 * 9/5x = 9 * (-5/9)

x = -5

Subtract. Write your answer in simplest form.
