Answer:
x = 1.636364
x = 1.64 (simplified)
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
0.7x=1.8−0.4x
0.7x=1.8+−0.4x
0.7x=−0.4x+1.8
Step 2: Add 0.4x to both sides.
0.7x+0.4x=−0.4x+1.8+0.4x
1.1x=1.8
Step 3: Divide both sides by 1.1.
1.1x/1.1=1.8/1.1
x=1.636364
x = 1.64 (simplified)
Answer:
x = 1.636364
Explanation:
0.7x = 1.8 − 0.4x
Simplify both sides of the equation0.7x = 1.8 − 0.4x
0.7x = 1.8 + −0.4x
0.7x = −0.4x + 1.8
Add 0.4x to both sides0.7x + 0.4x = −0.4x + 1.8 + 0.4x
1.1x = 1.8
Divide both sides by 1.1
1.1x / 1.1 = 1.8 / 1.1
x = 1.636364- PNW
If x+6>2x+4, which of the following is NOT a possible value for x? part 2
"2" is NOT a possible value for x.
The given inequality is:
[tex]x+6>2x+4[/tex]By subtracting "2x" from both sides of the equation, we get
→ [tex]x+6-2x> 2x+4-2x[/tex]
→ [tex]6-x> 4[/tex]
By subtracting "6" form both sides, we get
→ [tex]6-x-6>4-6[/tex]
→ [tex]-x> -2[/tex]
→ [tex]x>2[/tex]
Thus the above answer i.e., option D is the right approach.

Below is a set of data about temperatures. The range of a set of data is the distance between the lowest and highest value in the set. What is the range of these temperatures?
9°C, -3°C, 22°C, -5°C, 11°C, 15°C
Answer:
22-(-5)= 27
Step-by-step explanation:
22 is the highest temp. -5 is the lowest.
The range of the given temperatures is 27.
What is the range of the data set?"It the difference between the highest and lowest value of the data set."
For given example,
a set of data about temperatures is,
9°C, -3°C, 22°C, -5°C, 11°C, 15°C
First, we arrange the data values in ascending order.
-5°C, -3°C, 9°C, 11°C, 15°C, 22°C
Here, the lowest temperature = -5°C
the highest temperature = 22°C
So, the range of the data set would be,
R = highest temperature value - lowest temperature value
R = 22 - (-5)
R = 22 + 5
R = 27
Therefore, the range of the given temperatures is 27.

A drawing of a surfboard in a catalog shows its length as 8 4 over 9 inches. Find the actual length of the surfboard if 1 half inch length on the drawing corresponds to 3 over 8 foot of actual length. Submit your answer as a fraction using the format, 1 2/3. Do not include units, ft, in your answer.
Answer: [tex]6\dfrac13\text{ inches.}[/tex]
Step-by-step explanation:
Given: Length in drawing = [tex]8\dfrac49\ \text{inches}[/tex]
[tex]=\dfrac{9\times8+4}{9}\text{ inches}\\\\=\dfrac{72+4}{9}\text{ inches}\\\\=\dfrac{76}{9}\text{ inches}[/tex]
Also, half inch on drawing = [tex]\dfrac38\ foot[/tex] actual length.
1 inch on drawing = [tex]2\times\dfrac38 =\dfrac34\ foot[/tex]
[tex]\dfrac{76}{9}\text{ inches}=\dfrac{76}{9}\times\dfrac{3}{4}\ foot\\\\=\dfrac{19}{3}\text{ inches}\\\\=6\dfrac13\text{ inches}[/tex]

-18, -9, 18, or 9
Answer:-18
Step-by-step explanation:
6(x−3)+x=7x−18
Step 1: Simplify both sides of the equation.
6(x−3)+x=7x−18
(6)(x)+(6)(−3)+x=7x+−18(Distribute)
6x+−18+x=7x+−18
(6x+x)+(−18)=7x−18(Combine Like Terms)
7x+−18=7x−18
7x−18=7x−18
Step 2: Subtract 7x from both sides.
7x−18−7x=7x−18−7x
−18=−18
Step 3: Add 18 to both sides.

ACFG is a parallelogram, If AG = 2x + 10 and CF = 5x – 2, find CF.
Answer:
d. 18
Step-by-step explanation:
Lengths AG and CF of the parallelogram are equal.
i.e AG = CF
where AG = 2x + 10
CF = 5x -2
→ 2x + 10 = 5x-2
(collecting like terms): 5x - 2x = 10 + 2
→ 3x = 12
x=12÷3 = 4
∴ CF = 5x -2 = 5(4) -2 = 20 - 2 = 18
∴ CF = 18 (answer)

nestor fills a jar with marbles.each marble weighs 1/25 pound .the total weighs of all marbles is 3/5 pound how many marbles are in the jar
Answer:
Total number of jars will be 15.
Step-by-step explanation:
Given
The weight of each marble = 1/25 pound
The weight of all marbles = 3/5 pound
To determine
How many marbles are in the jar?
Let 'n' be the total number of jars
The total number of jars can be calculated by dividing the weight of all marbles by the weight of each marble.
Thus,
The total number of jars n = [weight of all marbles] / [weight of each marble]
= [3/5] / [1/25]
= [3 × 25] / [5 × 1]
= 75 / 5
= 15
Thus, total number of jars will be: n = 15
Answer:
15 marbles :) hope it helped a bit!
