Answer:

C

Step-by-step explanation:

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)

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

5. 5

Y=2x+4

At my school I don't get too much homework. My county doesn't have classes  on Wednesday so usually my teachers give work on Monday that is due on Wednesday and then work on Thursday due in Sunday. Also I only get homework for 3 classes Math, S.S and ELA, not science.

btw - im in 8th grade

Step-by-step explanation:

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

Answer:

Statement false.

Statement true.

Step-by-step explanation:

The left hand side of the equation is not equal to the right hand side, the statement is false.

[tex]16\% \: of \: 250 \: = 0.16 \: \times \: 250 = 40[/tex]

[tex]16\% \: of \: 250 \: is \: equal \: to \: 250\% \: of \: 16[/tex]

The result of both statement is the same, the statement is true.

Answer:

area =1/2 ×8×16=64

X=64 is answer

Answer:

In the video he said it was 4

Step-by-step explanation:

x/8=8/16

in order to be 1/2 x would equal 4

-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:

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]

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

Step-by-step explanation:

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.
