Answer:

Number of half-gallons containers of frozen yogurt = 28

Number of containers containing 1 gallon of frozen yogurt = 12

Step-by-step explanation:

Let [tex]x[/tex] denotes number of half-gallons containers of frozen yogurt and [tex]y[/tex] denotes number of containers containing 1 gallon of frozen yogurt.

[tex]x+y=40\,\,\,...(i)\\5x+9y=248\,\,\,...(ii)[/tex]

Multiply (i) by 5

[tex]5x+5y=200\,\,\,...(iii)[/tex]

Subtract (iii) from (ii)

[tex](5x+9y)-(5x+5y)=248-200\\5x+9y-5x-5y=48\\4y=48[/tex]

[tex]y=\frac{48}{4}=12[/tex]

Put [tex]y=12[/tex] in (i)

[tex]x+12=40\\x=40-12\\x=28[/tex]

its 3

Step-by-step explanation

15 percent *20 =

(15:100)*20 =

(15*20):100 =

300:100 = 3

Now we have: 15 percent of 20 = 3

Answer: The calculation adds up to 180.488, however i think you might need to round it up to 180.49.

Step-by-step explanation:

Answer:y=2x+4

explanation:

−10x+5y=20

Step 1: Add 10x to both sides.

−10x+5y+10x=20+10x

5y=10x+20

Step 2: Divide both sides by 5.

5y=10x+20

Step-by-step explanation:

When rounding to the nearest hundreth, any number with a tens digit under 5 will round down.

Answer:

A) $600

B) $1200

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 10%/100 = 0.1 per year,

then, solving our equation

I = 600 × 0.1 × 10 = 600

I = $ 600.00

The simple interest accumulated

on a principal of $ 600.00

at a rate of 10% per year

for 10 years is $ 600.00.

Answer:

x=14

Step-by-step explanation:

5x+3x+30 +2x+10 = 180 (angles on straight line add to 180)

10x+40 =180

10x=140

x=14

Answer:

Step-by-step explanation:

x/4-y/2=8, x-2y=32, x=32+2y

x/2+3y/4=-5, 2x+3y=-20, x=(-20-3y)/2

32+2y=(-20-3y)/2

64+4y=-20-3y

7y=-84

y=-12, since x=32+2y

x=32+2(-12), x=32-24=8

So the solution is the point (8, -12)

Answer:

its (8, -12)

Step-by-step explanation:

Answer:

a=7

Step-by-step explanation:

step one: divide both sides by 2

now you will have  [tex]a=\frac{14}{2}[/tex]

step two: divide 14 by 2

14/2 is 7 so a is equal to 7

-2z - 3 < 5 inequality is solved to z>-4.

Relationship between two expressions or values that are not equal to each other is called 'inequality.

The given inequality is -2z - 3 < 5

Minus two times of z minus three less than five.

-2z - 3 < 5

We need to solve this inequality, which means we need to solve of variable z.

Add 3 on both sides of inequality

-2z<8

Divide both sides by 2

-z<4

Multiply the given inequality by minus

z>-4

Hence, -2z - 3 < 5 inequality is solved to z>-4.

Answer:

x = -6

Step-by-step explanation:

4x - 2 + 3x - 7 = -51

Simplify

7x - 9 = -51

Move Terms

7x = -42

Divide.

x = -6

good luck, i hope this helps :)

Answer:

-6

Step-by-step explanation:

4x-2+3x-7=-51

we take minus two to the other side and it becomes plus two and -51+2 is -49

4x+3x-7=-49

and we take minus seven to the other side it becomes plus seven and -49+7 iis -42

4x+3x=-42

4x+3X = 7x

7x = -42

and to remove the x we divide both sides by 7

x = -42/7

-42/7 = -6

x=-6

Answer:

Equation: $83=5w+25 and 12 walks more

Step-by-step explanation:

Here is an equation: $83=5w+25

The $83 on the left represents the $83 goal for the bike (or the total amount of money that Taylor needs)

The 5w represents that Taylor earns $5 per time she walks the dog, with the w being the number of walks.

The +25 shows that Taylor has already earned $25 from walking the dog. (Not sure if you need it, but the $25 took 5 dog walks –– 5•5=25)

To solve:

83 = 5w + 25 –– Subtract 25 from both sides to get the variable term alone

58 = 5w –– Divide both sides by 5 to get w alone

11.6 = w –– Round this up to 12 because you can't really do 3/5 of a walk (this means Taylor needs to walk the dog 12 more times to earn enough to buy the bike)

Check:

83=5w+25 –– Replace w with 12

83=5(12)+25 –– Multiply

83=60+25 –– Add

83=85 –– This shows she will have $2 left over

Answer:

I think its D but im not completely sure. Good luck:)

Step-by-step explanation:

Step-by-step explanation:

Quadrant 1 is when the x axis and y axis is both positive.

Quadrant 2 is when the x axis is negative and the y value is positive.

Quadrant 3 is when the x axis and y axis is negative.

Quadrant 4 is when the x axis is positive and y value is negative.

When the point is on the x axis that means it y intercept is 0.

When the point on the y axis, it x intercept is 0.

2,4 is in quadrant 1

0,-3 is y axis

-1,1/2 is in the second quardrant

Answer:

y=5

x=-1

Step-by-step explanation:

5x-2y=-15

3x+8y=37

add 2y to both sides

5x=2y-15

divide both sides by 5

x=(2y-15)/5

x=2y/5-3

substitute for x

3(2y/5-3)+8y=37

6y/5-9+8y=37

add 9 to each side

6y/5+8y=46

subtract 8y from both sides

6y/5=46-8y

multiply both sides by 5

6y=5(46-8y)

6y=230-40y

46y=230

y=5

substitute for y

5x-2(5)=-15

5x-10=-15

5x=-5

x=-1
