7x+1=10x-9 what does x equal

Answer:

a) is 60 percent and b) is 55 percent

Step-by-step explanation:

a) = 60 percent

First count up all the squares. That's 10 squares in total. Now count up all the squares that are shaded. That's 6. So the amount that's shaded is 6/10, but we need to find that in percentage, so we divide. 6 divided by 10 is 0.6, or 60 percent. The answer to a) is 60 percent.

b) = 55 percent

First count up all the squares. That's 20 squares in total. Now count up all the squares that are shaded. That's 11. So the amount that's shaded is 11/20, but we need to find that in percentage, so we divide. 11 divided by 20 is 0.55, or 55 percent. The answer to b) is 55 percent.

The Percentages of shaded portion are 60% and 55% for Grid A and Grid B respectively.

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given here: Grid A) 2 rows and 5 columns B) 4 rows and 5 columns

Thus total number of grids for Grid A) and Grid B) are 10 and 20 boxes respectively.

%Shaded portion (Grid A)= 6/10 ×100

                                          =60%

%Shaded portion (Grid B)=11/20×100

                                          =55%

Hence, The Percentages of shaded portion are 60% and 55% respectively.

Answer:

V = 66 cm³

Step-by-step explanation:

The volume (V) of the prism is calculated as

V = Ah ( A is the area of triangular end and h is perpendicular height )

A = [tex]\frac{1}{2}[/tex] × 3 × 4 = 6 cm² and h = 11

V = 6 × 11 = 66 cm³

Answer:

the fraction 3/12

Step-by-step explanation:

it is saying that x/12 = 1/4

x = 1 × 12 / 4

x = 12/ 4

x = 3

the fraction 3/12

The caption mentions there are 937 total known characters.

The pie chart says 26% of these characters are hobbits, so there are

0.26 × 937 ≈ 243.62 hobbits

so at least 243 hobbits.

If 74 of them are female, then they make up

74/243 ≈ 0.304527 ≈ 30.5%

of the total number of hobbits.

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 4.25 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 4.25, so we can write it down as 100%=4.25.

4. We know, that x% equals 3.4 of the output value, so we can write it down as x%=3.4.

5. Now we have two simple equations:

1) 100%=4.25

2) x%=3.4

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=4.25/3.4

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.4 is what percent of 4.25

100%/x%=4.25/3.4

(100/x)*x=(4.25/3.4)*x       - we multiply both sides of the equation by x

100=1.25*x       - we divide both sides of the equation by (1.25) to get x

100/1.25=x

80=x

x=80

now we have:

3.4 is 80% of 4.25

BASICALLY 80%-

Step-by-step explanation:

did it on edge

Since 7 and 11 are both rational, the sum and difference are rational.

The answer is option A.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

A system of equations is a collection of two or more equations with the same set of unknowns. In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system.

Step-by-step explanation:

3x/2 - 2 > 7

3x/2 > 9

3x > 18

x > 6

for the line graphic below it seems you need to calculate x.

please consider that both angles together must be 180°, as they represent the full rotation area around one point on one side of a line.

8x + (4x + 60) = 180

8x + 4x + 60 = 180

12x = 120

x = 10
