3x - 6y = -48 And 2x + 3y = 38 How Would I Solve By Substitution? (2024)

Answer:

3- 0

there's 8 rows, and 48 tiles, 48/8=6, so there's no purple tiles needed

4- 240

36 students + 4 adults = 40, 40 people times 6 full buses = 240 people in total

5- 12

72 flags divided by 6 flags in each row = 12 rows

6- 10, 24, 38

composite numbers are like the opposite of prime numbers, you can divide them by more than just themselves and 1

hope this helps :)

3.) 24 (im not exactly sure)

4.) 240

5.) 12

6.) 10, 24, 38

Step-by-step explanation:

Answer: The correct unit rate = 2 pound per quart.

Her error instead dividing of that she multiplied both fraction.

Step-by-step explanation:

Given: Jessie said the rate [tex]\dfrac12[/tex] pound / [tex]\dfrac14[/tex] quart can be written as the unit rate [tex]\dfrac18[/tex] pound per quart.

The rate [tex]\dfrac12[/tex] pound / [tex]\dfrac14[/tex] quart = [tex]\dfrac{\dfrac{1}{2}}{\dfrac14} =\dfrac12\times\dfrac41=2\ \ \ \ \ \ [ \ \dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times\dfrac{d}{c}\ ][/tex]

The correct unit rate = 2 pound per quart.

Her error instead dividing of that she multiplied both fraction.

7) a = 48
8) b = 30
9) c = 188
10) d = 18
11) x = 32
12) y = 40

because x < 6 that means 6 is more than x so x has to be less than 6. your welcome;

Answer:

The equation is 216/20= 10.8 so about 11 dollars each

Step-by-step explanation:

Part B 216/ 15= 14.40 14.4 and 10.8 both round down so this awnser is reasonable

Step-by-step explanation:

Given

Total spending =$230

The cost of the skirt is $15

The Cost of the shirt is $10

Suppose she buys x skirts and y shirts

So, sum of the spending on skirts and shirts must be less than or equal to the $230

[tex]15x+10y\leq230[/tex]

Answer:

The artist used 8.6 inches more of silver wire

Step-by-step explanation:

Perimeter of the square

P = 4*a

P = 4*a = 40 in

a = 10 in

Each side of the square has a length of 10 in

The diameter of the circle is equal to the length of the side of the square

Diameter = 10 in

Perimeter of the circle

P_c = 2*π*radius = π*diameter

P_c = (3.14)*10 in = 31.4 in

Inches of silver wire (square) = 40 in

Inches of copper wire (circle) = 31.4 in

40- 31.4 in = 8.6 in

I Hope This Helps.

Answer: -3x + 7

Step-by-step explanation: All you have to do is combine like terms

First, you combine 3x - 6x which, will give you -3x

Second, you combine 12 - 5 which will give you 7

3x - 6x = -3x

12 - 5 = 7

So, combine the answers and you will get -3x + 7

Answer:

Greater than.

Step-by-step explanation:

Let the original value be x.

A 50% increase in x is given by

x + 50%x

=> x + 0.5x

=> 1.5x

Followed by a 33 [tex]\frac{1}{3}[/tex] % decrease in the value gives:

1.5x - 33 [tex]\frac{1}{3}[/tex] %(1.5x)

=> 1.5x - 0.33(1.5x)

=> 1.5x - 0.495x

=> 1.005x

Since 1.005x is greater than the original value, x, then:

A 50% increase followed by a 33 [tex]\frac{1}{3}[/tex] % decrease gives a value that is greater than the original.

Answer:

C

Step-by-step explanation:

you have a total of 18 data values which means you have to find the average of the 9th and 10th values; these values would be in the 3000 - 5999 because this interval contains data values 5 through 10

Answer:

a = 5.5

Step-by-step explanation:

Let the expression be written as;

Given 1/2 = a/11, find a

Cross multiply

1×11 = 2×a

11 = 2a

a = 11/2

a = 5.5

Answer: 1/15

Step-by-step explanation:

The lady wants to use 1/3 of her bead collection to make 5 bracelets for 5 friends.

This means that the amount of beads required for each bracelet is be 1/3 divided by the 5 bracelets:

= 1/3 ÷ 5

= 1/3 * 1/5

= 1/15 of her collection

When dividing fractions, you can instead multiply the inverse of the second fraction to get your answer.

Answer:

the damaged items expected in the case when the 23,025 capacitors produced is 75

Step-by-step explanation:

The computation of the damaged items expected in the case when the 23,025 capacitors produced is shown below:

= (5 × 23,025 capacitors) ÷ (1,535 capacitors)

= 75

Hence, the damaged items expected in the case when the 23,025 capacitors produced is 75

Answer:

x = 2, y= -1 Or (2, -1)

Step-by-step explanation:

Let’s solve the system using substitution. First we can set the equations equal to each other:

x-3= -2x +3

Now solve for x

3x-3= 3

3x = 6

x=2

Now that we have x, we can plug it back into one of the original equations to get y

y= x-3

y= 2-3

y = -1

Finally, the solution to the system of equations is (2, -1).

Answer:

(2,-1)

Step-by-step explanation:

1.) y = x - 3

y = -2x + 3

2.) Multiply top equation by 2

2y = 2x - 6

y = -2x + 3

3.) Add equations

3y = -3

4.) Divide 3 from each side

y = -1

5.) Substitute -1 for y in second equation

-1 = -2x + 3

6.) Solve

-4 = -2x

x = 2

Therefore, (2, -1)

-- these are called same side exterior angles, which means they are supplementary.

x + 9 + 2x + 6 = 180

3x + 15 = 180

3x = 165

x = 55

so, option B.

x=3

Step-by-step explanation:

(x+9)°=(2x+6)°(by alternate exterior angle)

9-6=2x-x

3=x

check

(x+9)°=(2x+6)°

put value

3+9=2×3+6

12=12

LHS = RHS

Answer:

Difference = 36

Step-by-step explanation:

Given that,

The boiling point of Oxygen = -183

The melting point of Oxygen = -219

We need to find the temperature difference of the melting point and the boiling point.

Difference = boiling point - melting point

= -183-(-219)

= -183+219

= 36

Hence, the required temperature difference is 36.
