B. By how much? (Hint find the unit rate for each)

Answers

Answer 1

Answer:

Mary

Step-by-step explanation:

Mary paid less for one bracelet. Tell me if I was wrong!

Mary Bought 5 Bracelets For $12.60. Danielle Bought 7 Bracelets For $15.75. A. Who Had The Better Buy
Mary Bought 5 Bracelets For $12.60. Danielle Bought 7 Bracelets For $15.75. A. Who Had The Better Buy
Answer 2
Danielle had a better deal for one bracelet because if you divide 15.75 by 7 it equals 2.25
But if you divide 12.60 divided by 5 it equals 2.52

I WILL MARK AS BRAINLIEST! Write an Equation that represents the points in the table

Answers

Answer:

y = 3x + 5

Step-by-step explanation:

Based on the table, as x increases by 1, y increases by 3. Moreover, when x = 0, y = 5. Therefore, the slope is 3 and the y-intercept is (0, 5).

Substitute the information for the variables in the slope-intercept form equation.

y = mx + b

m = slopeb = y-intercept value

Answer:

y=3x +5

Change the following mixed expressions to fractions and then simplify the complex fractions.

Answers

Answer:

[tex]\frac{3(a-7)}{4x(a-4)}[/tex]

Step-by-step explanation:

One is given the following expression:

[tex]\frac{2a^2-9a-35}{12x^3}*\frac{9x^2}{2a^2-3a-20}[/tex]

The most logical first step to solve this equation is to factor it. Rewrite each quadratic equation as the product of two linear equations. Unfortunately, no additional explanation can be provided. To prove that the product of the two linear terms are the factors of the quadratic term, one must distribute and simplify,

[tex]\frac{2a^2-9a-35}{12x^3}*\frac{9x^2}{2a^2-3a-20}[/tex]

[tex]\frac{(2a+5)(a-7)}{12x^3}*\frac{9x^2}{(2a+5)(a-4)}[/tex]

Now simplify this expression, then cancel common terms in the numerator and denominator,

[tex]\frac{(2a+5)(a-7)}{12x^3}*\frac{9x^2}{(2a+5)(a-4)}[/tex]

[tex]\frac{9x^2(2a+5)(a-7)}{12x^3(2a+5)(a-4)}[/tex]

[tex]\frac{3(a-7)}{4x(a-4)}[/tex]

I believe the answer would be
3(9-7)
4x(a=4)

If Gabrielle takes 19 minutes to run 2 miles then how much time does he take to complete 1 mile.

The above is the ‘b’ question.

We can get to know who long he takes to complete 1 mile taking the mean of the two in the double number line.

In this case it would be, the mean if 2 to get 1 and the mean of 19,

The mean of 2 is,

2miles / 2 = 1 mile.

And the mean of 19 mins is,

19 mins / 2 = 9.5 mins.

Hence, Gabrielle takes 9.5 mins to complete 1 mile.

Hope this helps you. Plz let me know if you have any doubts.

9.5 minutes because if she ran 2 miles in 19 minutes you would divide them both by 2 and 19/2=9.5
