Answer 1

Answer:

Estimate (eye-ballin'): around (3, 3)

Calculation: (2.6, 3.2)

Step-by-step explanation:

Given:

4x + 3y = 20

y = 2x - 2

Sophia's strat is absolutely correct. She makes two equations into one. This is called "substitution":

- Insert y of 2nd equation as y in 1st equation:

4x + 3(2x - 2) = 20

**Remember to multiply the entire thing by 3**

4x + 6x - 6 = 20

**Solve for x**

10x - 6 = 20

10x = 26

x = 2.6

Now that we have x, just plug it into any equation to find y (hint 2nd is easier):

y = 2(2.6) - 2

y = 3.2

COORDS: (2.6, 3.2)

Consider two consecutive odd positive integers. If their product is 23 more than their sum, what
are the two integers?

Answers

Answer:

Find two consecutive odd integers whose product is 23 more than their sum. Let x & x+2 be the 2 integers.

Step-by-step explanation:

The value of two consecutive odd positive integers are 5 and 6.

What are Integers?

A whole that can be positive , negative and zero is called integers.

Given that;

The product of two integers is 23 more that their sum.

Let two consecutive odd positive integers are x and x + 2.

Now, By the given condition we can formulate;

x (x + 2) = 23 + x + (x + 2)

x² + 2x = 23 + 2x + 2

x² + 2x = 25 + 2x

x² = 25

Take square root;

x = √25

x = ± 5

Since, Numbers are positive.

So, x = 5

And x + 1 = 5 + 1 = 6

Thus, The value of two consecutive odd positive integers are 5 and 6.

what is the approximate diameter of a sphere with a volume 34 cm the third power?​

Answers

Answer:

Diameter = 4cm________________

Step-by-step explanation:

volume = 34cm³

volume = 4/3×π×radius³

34cm³ = 4/3 × 3.14 × radius³

34cm³ = 12.56/3 × radius³

radius³ = 34×3/12.56

radius³ = 8

radius = ³√8

radius = 2cm

diameter = 2×radius

= 2×2

= 4cm

11) Ron paid x dollars for a pair of jeans. Tim bought the same pair of jeans for
half the price as Ron. If they paid a total of $45 for the 2 pairs, how much did
each spend on their jeans?
PLEASE HELP 20 POINTS!!

Answers

Answer:

Ron paid $ 30 for his pair of jeans, while Tim paid $ 15 for the same model of jeans.

Step-by-step explanation:

Given that Ron paid X dollars for a pair of jeans, and Tim bought the same pair of jeans for half the price as Ron, if they paid a total of $ 45 for the 2 pairs, to determine how much did each spend on their jeans you must perform the following calculation:

X + 1 / 2X = 45

1X + 0.5X = 45

1.5X = 45

X = 45 / 1.5

X = 30

So Ron paid $ 30 for his pair of jeans, while Tim paid $ 15 for the same model of jeans.
