Answer:

Cantaloupe = $6, peach=$5

Step-by-step explanation:

$8x+3y=63\\2x+3y=27\\$

Subtract the first one from the second one

$8x-2x+3y-3y=63-27\\6x=36\\x=6\\$

Plug in:

$2(6)+3y=27\\12+3y=27\\3y=15\\y=5$

Hope this helps plz hit the crown :D

Ok so the mass of a proton is 0.000000000000000000000000001672622 how do I make this in scientific notation

Soloha48 [4]

Answer:

1.7 x 10^-27

Step-by-step explanation

Move the decimal to the right until it's a single digit number, because you are moving it to the right, it would be a negative number. If you are able to round up then please do. Remember to check your significant figures if you're in chemistry.

Determine the solution set of each equation

maks197457 [2]

A=x1 = -8,x2 =2, B=x1= -5,x2=5, C=y1 = -4, y2 =5, D=y 18 over 5

alternative form

y=3 3over 5, =3.6

And E=x1=0, x2 =2 over 3

Alternative form

x1=0, x2=0.666667.

question A

Solving steps:Solve the quadratic equation

x²+6x-16=0

write 6x as a difference

x2 +8x-2x-16=0

factor out x for the expression

xx(x+8)-2x-16=0

factor out -2 from the expression

xx(x+8)- 2(x+8)=0

factor out x+8 from the expression

(x+8)x(x- 2)=0

when the product of factors equals 0,at least one factor is 0

x+8=0

x - 2=0

solve the equation for x

x= -8

x - 2=0

solve the equation for x

x= -8

x =2

the equation has 2 solution

x1 = -8,X2 =2

answer is

x1 = -8,x2 =2

Solving steps:Number of solution

x²+6x-16=0

Determine the number of solution using the

discriminant D =b²- 4ac

D =6²- 4x1x(-16)

simply the expression

D=100

Since D>0, the quadratic equation has 2 real solution

2 real solution

Answer is

2 real solution

Question B

Solving steps:Solve the quadratic equation

x²-25=0

Move the constant to the right-hand side and change its sign

x²=25

Take the square root of both sides of the equation and remember to use both positive and negative roots

x=+5

Write the solutions,one with a +sign and one with a -sign

x= -5

x=5

The equation has 2 solutions

x1= -5,x2=5

the answer is

x1= -5,x2=5

Solving steps:Number of solution

x²-25=0

Determine the number of solutions using the discriminant D=b²- 4ac

D=0²- 4x1x(-25)

Simply the expression

D=100

Since D>0,the quadratic equation has 2real solutions

Answer is

2real solutions

answer of question C is

y1 = -4, y2 =5

Answer of question D is

y 18 over 5

alternative form

y=3 3over 5, =3.6

Answer of question E is

x1=0, x2 =2 over 3

Alternative form

x1=0, x2=0.666667

Please mark as brainiest

Peppers = 12 for $9
Tomatoes = 6 fir $4
____________
SO NOW
____________
$\huge{SOLUTION:- }$
____________
For 9 cucumbers = as 6 cucumbers is for $2 then 9 will be of $3........1️⃣

For 18 peppers = as 12 peppers are for$9 so 18 will be of $12.........2️⃣

For 21 tomatoes =as 6 tomatoes are for $4 then 21 tomatoes are $14 .......3️⃣

Now add 1️⃣ +2️⃣ + 3️⃣

here $3 +$12 + $14= $29

A shipping box has the dimensions shown what is the volume of the box in cubic yards? 1-4 yard 1-4 yard 1-2 yard

andriy [413]

The required picture is attached below :

Answer:

1 /32 yard³

Step-by-step explanation:

The volume of box can be obtained using the relation :

V = length * width * height

Length = 1/4 yards

Width = 1/2 yards

Height = 1/4 yards

Hence,

Volume (V) = 1/4 yards * 1/2 yards * 1/4 yards

Volume (V) = (1/4 * 1/2 * 1/4)(yard³)

Volume (V) = 1 / 32 yard³
