Answer:

  • trail mix: $1.25
  • jelly beans: $3.50 per pound

Step-by-step explanation:

The difference between double the first purchase and the second purchase is $7 and 2 pounds of jelly beans. Hence a pound of jelly beans is $3.50.

  (4t +8j) -2(2t +3j) = (33) -2(13) . . . . . let t and j represent pounds of trail mix and jelly beans, respectively

  2j = 7 . . . . . . . . . . simplify

  j = 7/2 = 3.50

Using that value in the first purchase, we get ...

  2t +3(3.50) = 13

  2t = 13 -10.50

  t = 2.50/2 = 1.25

A pound of trail mix is $1.25.

xz_007 [3.2K]

Answer:

\frac{16}{195}

Step-by-step explanation:

To obtain the result of a fractions multiplication we need to multiply both numerators and the divide by the multiplication of the denomitators. In general, given a,b,c,d real numbers with b and d not zero, we have that

\frac{a}{b}*\frac{c}{d}=\frac{a*c}{b*d}

Substituting a,b,c and d for 8,15,2 and 13 we obtain that

\frac{8}{15}* \frac{2}{13} =\frac{16}{195}

What is the supplement angle of 100?​
aleksley [76]

Answer:

An angle measuring 100 degrees would be supplementary to any angle measuring 80 degrees, but it cannot be called supplementary by itself. "Complementary" and "supplementary" are terms that describe the relationship between two angles. They are comparative words like "larger."

3x + 4y = 12<br> x + 2y = 10
borishaifa [10]

Answer:

x=-8 and y=9

Step-by-step explanation:

rewrite the equations to x+2y=10,3x+4y=12

sub 2y from both sides x+2y-2y=10-2y

substitue x=10-2y in 3x +4y=12

3(-2y+10)+4y=12

distribute

add-30 to both sides

divide both sides by -2

y=9

sustitute 9 for y in -2y+10=x

x=-8

An olympian swam the 200-meter freestyle at a speed of 1.8 meters per second. An olympic runner ran the 200-meter dash in 21.3 s
Maurinko [17]

Answer:

7.6m/s

Step-by-step explanation:

Find the time the Olympian swam

Speed=distance/time ⇒⇒Time=distance/speed

Distance=200m , speed= 1.8m/s   t= 200/1.8 = 111.11 seconds

Find the speed of the Olympic runner

Distance=200m  time = 21.3 sec  

s=200/21.3 = 9.4 m/s

Difference in speed= 9.4-1.8= 7.6m/s
