O=orange
a=apple

equation 1
3o+a=$1.86
a=$1.86-3o

use a=$1.86-3o in equation 2

equation 2 
2o+3a=$2.15
2o+3($1.86-3o)=$2.15
2o+$5.58-9o=$2.15
$5.58-7o=$2.15
$5.58=$2.15+7o
$3.43=7o
$0.49=o

then use $0.49=o for equation 1.

equation 1

3($0.49)+a=$1.86
$1.47+a=$1.86
a=$0.39

so an apple is $0.39.

What is Q=R+Rst; solve for s
oksano4ka [1.4K]

Step-by-step explanation:

q=r+rst

Rewrite the equation as 

r+rst=q

Subtract r from both sides of the equation.

r st=q−r

Divide each term by rt

(r st )/rt=(q/rt)−(r/rt)

Cancel the common factor.

(

s=(q/rt)−1/t

Mike traveled to Greensboro by car. Going there took 6 hours, and the return trip was four hours. Mike averaged a speed of 81 mi
Marat540 [252]

return time is 4 hours

The average speed of returning 81 mph

Distance traveled while returning

\Rightarrow d=81\times 4=324\ miles

the average speed of the entire trip is

\Rightarrow v_{avg}=\dfrac{2\times 324}{6+4}=\dfrac{648}{10}=64.8\ mph

Question 4 (1 point) Determine whether the ordered pair (3,28) is a solution to the equation 2x- y/2 = -8 (3, 28) Is a solution
bulgar [2K]

Answer:

It is a solution

Step-by-step explanation:

Given

2x - \frac{y}{2} = -8

Required

Determine if (3,28) is a solution

(3,28) implies that:

x = 3

y = 28

To check if it is a solution, we simply substitute values for x and y in the given equation;

2x - \frac{y}{2} = -8

2(3) - \frac{28}{2} = -8

6 - 14= -8

-8= -8

Since both sides of the equation are equal; then, Yes, it is a solution
