3(x-4)=2(-2x+1) please help

Answers

Answer 1
Answer: x=2.

Step by step:

3(x-4)=2(-2x+1)

3x-12=-4x+2

7x-12=2

7x=14

x=2
Answer 2

Answer:

[tex]\boxed{\boxed{\sf x=2}}[/tex]

Step-by-step explanation:

[tex]\sf 3\left(x-4\right)=2\left(-2x+1\right)[/tex]

Expand, Apply Distributive property:

→ [tex]\sf 3x-12=-4x+2[/tex]

Add 12 from both sides:

[tex]\sf 3x-12+12=-4x+2+12[/tex]

→ [tex]\sf 3x=-4x+14[/tex]

Add 4x from both sides:

[tex]\sf 3x+4x=-4x+14+4x[/tex]

→ [tex]\sf 7x=14[/tex]

Divide both sides by 7:

[tex]\sf \cfrac{7x}{7}=\cfrac{14}{7}[/tex]

→ [tex]\sf x=2[/tex]

40 cookies are in a jar. 1/5 of the cookies are chocolate cookies. Someone eats 1/4 of the chocolate cookies. How many cookies remain in the jar?​

Answers

6 cookies remain in the jar

Based on the number of cookies in the jar and the number eaten by the person, the number of cookies remaining is 38 cookies.

The total number of chocolate cookies is:

= Total cookies x Percentage that is chocolate

= 40 x 1/5

= 8 cookies

Someone eats 1/4 of this which is:

= 8 x 1/4

= 2 cookies

The number of cookies left is:

= Number of cookies - Number of cookies eaten

= 40 - 2

= 38 cookies

In conclusion, there are 38 cookies remaining.

What is the surface area of the cylinder with height 8 km and radius 4 km? Round
your answer to the nearest thousandth.

Answers

The solution is: the surface area of the cylinder is 301.44 km².

Here, we have,

from the given diagram, we get,

For surface area of a cylinder:

A = 2(π) × (radius) × (height) + 2(π)×(radius squared)

For the first half of that equation:

2(π) × (radius) × (height)

2 × (3.14) × (4) × (8)

= 200.96 km²

Now the second half of that equation, the area of the circle ends:

2(π)×(radius squared)

= 2 × (3.14) × (4) × (4)

= 100.48 km²

Add them up:

200.96 km² + 100.48 km² = 301.44 km²

Hence, The solution is: the surface area of the cylinder is 301.44 km².

The value of an autographed baseball card increased from $39 to $65.
What is the percent increase in value of the baseball card? Round to the nearest hundredth of a percent.

Answers

Answer: The percent of increase is 66.67%.

Step-by-step explanation:

Find the percent of increase of baseball cards.

Step 1: Subtract the starting value from the final value.

                                       65 - 39 = 26

Step 2: Take the value you get and divide it by the starting value.

                                       26 ÷ 39 = 0.666667

Step 3: Multiply what you get by 100.

                                       0.666667 × 100 = 66.6667

Step 4: Round what you get the nearest hundredth of a percent.

                                        66.6667 → 66.67%

Answers

Hello there!

Grace has $105 for pizzas and a cake.

She sets aside $25, so we subtract:

105-25=80

So she has $80 for pizzas.

Now, to find out how many pizzas Grace can buy, we take $80 and divide it by the price of one pizza (9.25):

The approximate answer is 8.6

The sum of two numbers is 52. The greater number is 4 more than the smaller number. Which equation can be used to solve for the smaller number ?
×-(×+4)=52
×+(×+4)=52
×(×+4)=52
×(×-4)=52​

Answers

Answer:Let's assume x be the smaller number.

Given that, The greater number is 4 more than the smaller number.

So, greater number= x+4.

It's also given that, The sum of two numbers is 52. Which means sum of x and x+4 must be equa to 52. Hence,

x + (x + 4) = 52
