Answer:

x = - 1

Step-by-step explanation:

Given

15x - 7 = 4x - 18 ( subtract 4x from both sides )

11x - 7 = - 18 ( add 7 to both sides )

11x = - 11 ( divide both sides by 11 )

x = - 1

Jordan bikes at a speed of 8 2/3mph. How many miles will he bike in:<br> 45 minutes?

olganol [36]

Answer:

6 miles

Step-by-step explanation:

You Can make a proportion

$\frac{26/3 miles}{60 minutes}$ = $\frac{x}{45 minutes}$

Now cross multiply

45*26/3 is 360

and 60*x is 60x

make an equation

60x=360

x=6

So 6 miles

p + 2 = 5 ==> p = 3

3p + 2 = p + 3 ==> 2p = 2 ==> p = 1

3k + 5 = 2k + 2 ==> k = -3 (niemożliwe; lewa strona wagi ma większą wagę)

2w + 10 = 4w + 7 ==> 2w = 3 ==> w = 3/2

d + 9 = 3d + 2 ==> 2d = 7 ==> d = 7/2

W drugim zadanie każda litera reprezentuje wagę jednego z obiektów. Na przykład 3k + 4 reprezentuje całkowitą wagę 3 kół i 4 ciężarów, każdy o wadze 1 kg.

Trzecie zadanie to tylko połączenie dwóch pozostałych.
