Help plz. 4x^2-10x=84

Answers

Answer:

my brain just died sorry

Step-by-step explanation:

Answer:

x = 6

4x2−10x=84

Step 1: Subtract 84 from both sides.

4x2−10x−84=84−84

4x2−10x−84=0

Step 2: Factor left side of equation.

2(2x+7)(x−6)=0

Step 3: Set factors equal to 0.

2x+7=0 or x−6=0

−7

or x=6

What is linear equation in one variable?

A linear equation in one variable is an equation which has maximum of one variable of order 1. It is of the form ax + b =0, where x is the variable.

Solving Linear Equation in one variable

For solving an equation having one variable, the following steps are followed:

Step1: Using LCM, clear the fractions if any.Step2: Simplify both sides of the equation.Step 3: Isolate the variable.

According to the given question

We have, a linear equation in variable r.

2r +7 =16

⇒ 2r + 7 -7 = 16 -7

⇒ 2r = 9

⇒ r = 9/2

Hence, the value of r is 9/2 for the given linear equation 2r + 7 = 16.

Kay spends 250 min/wk exercising. Her ratio of time spent on aerobics to time spent on weight training is 3 to 2. How many minutes per week does she spend on aerobics? How many minutes per week does she spend on weight training?

Answers

Time spent on aerobics is 150 minutes per week and time spent on weight training is 100 minutes per week

Solution:

Given that,

Kay spends 250 min/wk exercising

Therefore,

Exercising = 250 minutes per week

Ratio of time spent on aerobics to time spent on weight training is 3 to 2

Aerobics : weight training = 3 : 2

Let the time spent on aerobics be 3x

Let the time spent on weight training be 2x

Thus,

3x + 2x = 250

5x = 250

x = 50

Thus,

Time spent on aerobics = 3x = 3(50) = 150

Time spent on weight training = 2x = 2(50) = 100

Thus, Time spent on aerobics is 150 minutes per week and time spent on weight training is 100 minutes per week

The sum of three consecutive numbers is 84. What is the largest of these numbers? (5 points) a 28 b 26 c 29 d 27

Answers

Answer:

The answer is c.29

Step-by-step explanation:

I used Google xD

Answer:

Largest number = 29

Step-by-step explanation:

Let the consecutive numbers by (x + 1) ; (x + 2) and (x +3)

x +1 + x + 2 + x + 3 = 84 {Combine like terms}

x + x +x + 1 + 2 + 3 = 84

3x + 6 = 84

3x = 84 - 6

3x = 78

x = 78/3

x = 26

Largest number = x + 3 = 26 + 3

=29

23.82600 round to three significant figures

Answers

Answer:

23.8 i think

Step-by-step explanation:

Answer:

[tex]23.83[/tex]

Step-by-step explanation:

[tex]--------------------------------------------[/tex]

According to Maths3000, Rounding to 3 significant figures is probably the most common way of rounding off. Rounding the number off to 3 significant figures means you require 3 non-zero digits from the start of the number. So in example 1, 27.1258 gets rounded to 27.1 figures.[tex]--------------------------------------------[/tex]

It is 23.83 because rounding by three significant figures is picking three of the last numbers, and rounding the 4th number. In this case, 6 is more than 5, so 23.82 becomes 23.83

Jina is saving money to buy a bike. She has $63 and is going to save an additional $9 each week. The bike costs $198. In how many weeks will she have
enough money to buy the bike?
(a) Write an equation that could be used to answer the question above.
First, choose the appropriate form. Then, fill in the blanks with the
numbers 63, 9, and 198. Let w represent the number of weeks.

Answers

Answer:

Jina will have enough money to buy the bike in 15 weeks

Step-by-step explanation:

y = mx + b

198 = 9x + 63

Subtract 63 from both sides;

135 = 9x

Divide both sides by 9;

x = 15

b. The player with the lowest score sank 2 baskets and missed 8. What was the lowest score?

c. Write an expression using addition to find out what the score would be if a player sank 5 baskets and missed 5 baskets.

Answers

Answer/Step-by-step explanation:

A. (7 x 10) = 70

(3 x -15) = -45

70 + -45 = 25

B. (2 x 10) = 20

(8 x -15) = -120

20 + - 120 = - 100

C. (5 x 10) + ( 5 x -15) or 5 x (10 + -15)

5 x 10 = 50

5 x -15 = -75

50 + -75 = -25
