On a bicycle ride,Betty rode 7 miles in 2 hours. At the same rate of speed,how far could she ride in 8 hours?Please hurry

Gnoma [55]

It is given in the question that

Ann, Chang, and Kareem sent a total of 89 text messages over their cell phones during the weekend. Ann sent 9 fewer messages than Chang. Kareem sent 3 times as many messages as Ann.

Let number of messages Chang sent be x. And Ann sent 9 fewer than Chang, so Ann sent (x-9) messages. And Kareem sent 3 times as many messages as Ann, so Kareem sent 3(x-9) messages.

And the total messages are 89. That is

$x+x-9+3(x-9)=89$

Combining like terms

$x + x - 9 + 3x-27 =89
\\
5x -36=89
\\
5x = 125
\\
x =25$

So Chang sent 25 messages, Ann sent

$25-9=16 messages$

And Kareem sent

$3*16 = 48 messages$

Answer:

A.

General Formulas and Concepts:

Math

Fraction conversions to decimal

Algebra I

Reading a Cartesian plane
Coordinates (x, y)

Step-by-step explanation:

Where the 2 lines intersect is the solution to the systems of equations.

5/2 would be 2.5 and 4/3 would be approximately 1.333.

Our (x, y) for the graph is (2.405, 1.357), so our answer would be A.

What is the slope and y-intercept for the graph of the equation Y= 4/5 x - 3 ?

vichka [17]

So,

The slope-intercept form is as follows:
y = mx + b

"m" is the slope, and "b" is the y-intercept. The y-intercept for this equation is (0,b).

Our equation is $y= \frac{4}{5} x-3$

That means that $\frac{4}{5}$ is the slope, and -3 is the y-intercept.

Kerry purchased a used car for 14,4000. And had to pay 8% sales tax how much did she pay

saul85 [17]

Answer:

Kerry should pay = 155520

Step-by-step explanation:

Total amount paid = 14,4000 + 8% of 14,4000

It is given that,

Kerry purchased a used car for 14,4000. And had to pay 8% sales tax

To find the 8% of 14,4000

8% of 14,4000 = (8*144000)/100 = 11520

To find total amount paid

Total amount paid = 14,4000 + 8% of 14,4000

= 14,4000 + 11520 =155520

Therefore Kerry should pay = 155520

Richard is given one of four pieces of equal-sized fabric. After using some of his fabric for a project, he has 5/6 of a square

ValentinkaMS [17]

Answer:

Richard used $2\frac{1}{12}\ yd ^2$ of fabric for his project.

Step-by-step explanation:

Given:

Total amount of fabric = $11\frac23\ yd^2$

Now To convert a mixed fraction to an improper fraction, Multiply the whole number part by the fraction's denominator, Add that to the numerator,Then write the result on top of the denominator.

$11\frac23\ yd^2$ can be Rewritten as $\frac{35}{3}\ yd^2$
