What is the value of x in the equation 4x+8y=40 when y=0.8

Answers

inpus 0.8 for y
4x+8(0.8)=40
4x+6.4=40
minus 6.4 both sides
4x=33.6
divie both sides by 5
x=8.4

x=8.4 when y=0.8

4x+8y=40
4x + (8x.8)= 40
4x + 6.4 = 40
4x = 33.6
x = 8.4

What is X? 3(4x−3)= -4+7

Answers

x = 1

Step-by-step explanation:

$3(4x - 3) = - 4 + 7$

Expand:

$3(4x - 3) = 12x - 9 \n 12x - 9 = - 4 + 7$

Simplify:Addvalues

$12x - 9 = 3$

Collect like terms and simplify

$12x = 3 + 9 \n 12x = 12$

Divide both sides of the equation by12

$(12x)/(12) = (12)/(12)$

Simplify

$x = 1$

Answer:

x = 1

Step-by-step explanation:

Original Equation:

3(4x - 3) = -4 + 7

Use the distributive property.

3 x 4x = 12x

3 x -3 = -9

Equation:

12x - 9 = -4 + 7

Add 4 to both sides.

12x - 5 = 7

Add 5 to both sides.

12x = 12

Divide both sides by 12

x = 1

Hope I helped :)

Solve the percent problem. 6. How much is 40% of $80 ?

of= multiply

1. Turn 40% to decimal.

40% = 0.40

2. Multiply

0.40(80)= 32

So your answer is 30 dollars.

Final answer:

To solve the percentage problem, you multiply $80 by 0.40 (which is the decimal equivalent of 40%). The result is $32.

Explanation:

The question is asking for the value of 40% of $80. To solve this percent problem, you will need to multiply the total amount ($80) by the percentage (40%). However, since the percentage is given as a whole number, you must first convert it to a decimal by dividing by 100. So, 40% becomes 0.40 as a decimal.

To find out what 40% of $80 is, you then multiply $80 by 0.40. Here's the math:

$80 x 0.40 = $32

So, 40% of $80 equals $32.
