Fabio and carlos play on a basketball team together. in the last game, fabio had 777 points less than 222 times as many points a

jasenka [17]

For this case, the first thing we must do is define variables.

We have then:

f: number of points that fabio scored.

c: number of points that Carlos scored.

We now write the equation that models the problem:

$f = 2c - 7$

Then, for f = 31 we have:

$2c - 7 = 31$

From here, we clear the number of points:

$2c = 31 + 7$

$2c = 38$

$c = \frac{38}{2}$

$c = 19$

Answer:

The equation to find the number of carlos points is:

$2c - 7 = 31$

Then, Carlos scored:

$c = 19$

The ratio of the lengths of the sides of △ABC is 3:6:7. M, N, and K are the midpoints of the sides. Perimeter of △MNK equals 7.4

artcher [175]

Answer:

AB=2.775

BC=5.55

CA=6.475

Step-by-step explanation:

Since midpoints split their sides in half, we can see that the triangle MNK formed by the midpoints will be half the perimeter of the triangle ABC. Since P of MNK = 7.4, we know that the perimeter of ABC = 7.4 * 2, which is 14.8. Now we can split the 14.8 so that it follows the ratio.

3+6+7=16

14.8/16=0.925

AB=0.925*3=2.775

BC=0.925*6=5.55

CA=0.925*7=6.475

a small table is 2 feet by 3 feet a large table is twice as long and rwice as wide as the small table. Whats the area of the lar

Scorpion4ik [409]

Answer:

The area of larger table is 24 square feet.

Step-by-step explanation:

Given are the length and width of small table

$l_s = 2\ ft\\w_s = 3\ ft$

The area of a rectangular table is calculated by multiplying the length and width. It is also given that the length and width of the larger table is double the length and width of small table

So the length and width of larger table will be:

$l_l = 2*2 = 4\ feet\\w_l = 3*2 = 6\ feet$

The area of larger table will be:

$A_l = l_l*w_l\\= 4 * 6\\=24\ ft^2$

Hence,

The area of larger table is 24 square feet.

Lupe can ride her bike at a rate of 20 mph when there is no wind. On one particular day, she rode 2 miles against the wind and n

lana [24]

Let wind speed = x mph

when she rode 2 miles against the wind we have:-
speed = distance / time so
20 - x = 2 / t -------(1) where t is the time she took.

when riding with the wind we have

20 + x = 3 / t--------(2) adding equations (1) and (2):-

40 = 2/t + 3/t
40 = 5/t
t = 5/40 = 1/8 hr

x = 20 - 2 / 1/8 = 20 - 16 = 4

Wind speed was 4 mph Answer
