2x-3y=1

+2x+3y=2

4x=3 substitute 3/4 for x in the first equation..you get y=2/9.

x=3/4

+2x+3y=2

4x=3 substitute 3/4 for x in the first equation..you get y=2/9.

x=3/4

**Answer:**

**Step-by-step explanation:**

Two lines in a plane can intersect, overlap, or be parallel. When two lines intersect they have a common point which lies on both lines. when graphed represent straight lines. Adding the two equations uses the Elimination method to solve for x and y. The x and y value obtained is the common point lying on both lines.

Question

Brainliest FOR WHO HELP ME a spherical mini donut hole has a diameter of 6 centimeters. A large spherical donut hole has a diameter of 9 centimeters. Approximately how much greater is the volume of a large donut hole than the volume of a mini donut hole? 86 cm³
113 cm³
226 cm³
268 cm³

Solution 1

4/3 *3.14*4.5^3-Donut Hole

4/3 *3.14*3^3-Mini Donut

Then Subtract the greater answer from the smaller one.

4/3 *3.14*3^3-Mini Donut

Then Subtract the greater answer from the smaller one.

Solution 2

The answer is 113 if my math is correct

Question

Which is deeper? 1.4 m or 4 ft

Solution 1

1feet 0,3048cm

so 4 ft=1,2192

but 1,4 deeper than 4ft

so 4 ft=1,2192

but 1,4 deeper than 4ft

Solution 2

1.4 meters would be deeper

Question

What is the value of x in the equation 1.5(x + 4) – 3 = 4.5(x – 2)?

Solution 1

Hello!

Step 1: Simplify both sides of the equation.

1.5(x+4)−3=4.5(x−2)

(1.5)(x)+(1.5)(4)+−3=(4.5)(x)+(4.5)(−2)(Distribute)

1.5x+6+−3=4.5x+−9

(1.5x)+(6+−3)=4.5x−9(Combine Like Terms)

1.5x+3=4.5x−9

Step 2: Subtract 4.5x from both sides.

1.5x+3−4.5x=4.5x−9−4.5x

−3x+3=−9

Step 3: Subtract 3 from both sides.

−3x+3−3=−9−3

−3x=−12

Step 4: Divide both sides by -3.

−3x−3=−12−3

x=4

Hope this helps! Cheerio, and have a lovely day!

Step 1: Simplify both sides of the equation.

1.5(x+4)−3=4.5(x−2)

(1.5)(x)+(1.5)(4)+−3=(4.5)(x)+(4.5)(−2)(Distribute)

1.5x+6+−3=4.5x+−9

(1.5x)+(6+−3)=4.5x−9(Combine Like Terms)

1.5x+3=4.5x−9

Step 2: Subtract 4.5x from both sides.

1.5x+3−4.5x=4.5x−9−4.5x

−3x+3=−9

Step 3: Subtract 3 from both sides.

−3x+3−3=−9−3

−3x=−12

Step 4: Divide both sides by -3.

−3x−3=−12−3

x=4

Hope this helps! Cheerio, and have a lovely day!

Solution 2

The** required value** of **x** in the **equation** is **3.43.**

Given that,

**Equation** is, 1.5(x + 4) – 3 = 4.5(x – 2)

We need to** find,**

The **value** of **x** in the **equation.**

**According** to the **question**,

**Equation** = 1.5(x + 4) – 3 = 4.5(x – 2)

**Simplify **the **equation**, to **determine** the** value **of **x **

The **value **to **x** is** 3.42.**

Hence, The** required value **of **x** in the** equation** is** 3.43.**

Question

What fraction makes the equation true?
2/3 x blank = 8/12

Solution 1

So, find x to complete x =

But, since 8/12 is already equal to 2/3, this means:

**x=1**

But, since 8/12 is already equal to 2/3, this means:

Its 1!! Hope This Helps

Question

20 ounces of cereal for 4.40 or 16 ounces of the same brand for 3.68 which is the better buy

Solution 1

The better buy is **16** **ounces **of the same **brand **for 3.68.

Given that

20 **ounces **of **cereal **for 4.40 or 16 ounces of the same brand for** 3.68.**

We have to **determine**

Which is the better **buy**?

**According **to the **question**

The amount of **cereal **for 20 ounces is** 4.40.**

Then

The cost per cereal is,

The cost per **cereal **is **4.45.**

And the amount of **cereal **for 16 ounces is** 3.68.**

Then

The cost per cereal is,

The cost per **cereal **is **4.34.**

Hence, the better buy is **16** ounces of the same **brand **for 3.68.

To know more about **Equation **click the link given below.

Solution 2

20 ounces of cereal for 4.40 would be the better buy because it costs 0.22/ounce. Were as with the 16 ounces for 3.68 would cost 0.23/ounce.

Question

If you buy 3 sandwiches for 4.95 or 4 sandwiches for 6.72 which is the better buy

Solution 1

$4.95 for 3 sandwiches is $1.65 for each sandwich.

4.95/3=1.65

$6.72 for 4 sandwiches is $1.68 for each sandwich.

6.72/4=1.68

Obviously, go for the three sandwiches!

4.95/3=1.65

$6.72 for 4 sandwiches is $1.68 for each sandwich.

6.72/4=1.68

Obviously, go for the three sandwiches!

Question

BRAINLIEST FOR WHO EVER GET THIS RIGHT triangle has a leg of 6 yards and a hypotenuse of 8 yards. What is the length of the other leg? Enter your answer, as a decimal rounded to the nearest tenth, in the box.
yd

Solution 1

Using the Pythagorean theorem a^2 + b^2 = c^2

where a and b are the legs and c is the hypotenuse

so a = 6 and c = 8

lets solve for b

6^2 + b^2 = 8^2

36 + b^2 = 64

b^2 = 64 - 36

b^2 = 28

b = sqrt(28)

b = 5.29

b = 5.3 yards

where a and b are the legs and c is the hypotenuse

so a = 6 and c = 8

lets solve for b

6^2 + b^2 = 8^2

36 + b^2 = 64

b^2 = 64 - 36

b^2 = 28

b = sqrt(28)

b = 5.29

b = 5.3 yards

Solution 2

**Answer:**

It's 5.3 yd, hope this helps

Question

Six less than four times a number is 26. What is the number?

Solution 1

Hello there!

The number would be - 8

lets do the work:

(8 x 4) - 6 = 26

Therefore your answer is 8.

Hope this helps!

~DL

The number would be - 8

lets do the work:

(8 x 4) - 6 = 26

Therefore your answer is 8.

Hope this helps!

~DL

Solution 2

Okay, lets see here. So since we know that 26 is six less than the actual answer, we'll add 6 to 26 which gives us 32. Then we'll do 32 divided by 4, which is 8.
