Answer:

(A) the subtraction property of equality

Step-by-step explanation:

Given

The steps in the question

Require

Justify step 2 to 3

Write out step 2:

[tex]-4x+9 = 2x+10[/tex]

Apply subtraction property by subtracting 2x from both sides

[tex]-4x-2x+9 = 2x-2x+10[/tex]

[tex]-6x+9 = 10[/tex]

Notice that the above equation is represented in step 3.

Hence, option A answers the question.

A. the subtraction property of equality

2+1= 3

x−1

first, draw the graph for equations y=2x+1 and y=

2

x−1

for y=2x+1

substitute y=0 we get, 2x+1=0⟹x=−0.5

substitute x=0 we get, y=1

therefore, y=2x+1 line passes through (0.5,0) and (0,1) as shown in fig.

Hence, y≥2x+1 includes the region above the line.

for y=

x−1=0⟹x=2

substitute x=0 we get, y=−1

therefore, y=2x+1 line passes through (2,0) and (0,-1) as shown in fig.

Hence, y>

Answer:

D: Reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually 10%.

Step-by-step explanation:

In statistics, type I error is when we reject the null hypothesis even when it is true.

Now, the claim which is the null hypothesis is that that 10 % of children suffer from a certain disorder.

This means that a type I error will be;

Reject the claim that the percentage of children who suffer from the disorder is equal to 10% when that percentage is actually 10%.

Answer:

Step-by-step explanation:

6.7578 *x = 13 divide both sides by 6.7578

[tex]\frac{6.7578}{6.7578} *x = \frac{13}{6.7578}[/tex]

Answer:

Step-by-step explanation:

Given the area of the square as A = 98ft²

The side length of the square will be equivalent to the diameter of the circle.

First we need to get the length of the square.

Area of a square = L^2

98 = L²

L = √98

L = 9.89 ft

Hence the diameter of the circle is 9.89 ft

radius = diameter/2

radius = 9.89/2

radius ≈ 4.95 feet

Hence the radius of the circle is approximately 4.95 feet

Answer:

it means when x =0

so 6*0+12y=60

12y=60

y=5

Step-by-step explanation:

Answer:

In y intercept x = 0

so,we replace 0 in place of x

Step-by-step explanation:

6*0+12y=60

0+12y=60

y=60/12

y=5

Answer:

0.6 or 3/5

Step-by-step explanation:

If cos(t) = 4/5, then, taking the arccos of both sides, t ≈ 36.86989765. Taking the sin of that gives you 0.6, or 3/5 in fraction form.

Answer:

125 boys, 90 girls and 20 adults

Step-by-step explanation:

Let the number of boys be x

Let the number of girls be y

Let the number of adults be z

If there are 235 people at the summer camp, then;

x + y+ z = 235 ..... 1

If there are 35 more boys than girls, then;

x = y + 35 .... 2

If there are 70 fewer adults than girls then;

y = z - 70

z = y - 70....3

Substitute 2 and 3 into 1;

x + y+ z = 235 ..

(y+35)+y+(y-70) =235

3y -35 = 235

3y = 270

3y/3 = 270/3

y = 90

Since x = y + 35

x = 90 + 35

x = 125

Also z = y - 70

z = 90+70

z = 20

There are 125 boys, 90 girls and 20 adults

Answer:

There are 90 girls, 125 boys, and 20 adults.

Step-by-step explanation:

Let x be the number of girls. How many boys were there?

x + 35

How many adults were there?

x - 70

We know that 235 people are at RSM summer camp. Use this to make an equation.

x + (x + 35) + (x - 70) = 235

x + x + 35 + x - 70 = 235

3x - 35 = 235

3x - 35 + 35 = 235 + 35

3x = 270

3x ÷ 3 = 270 ÷ 3

x = 90

x, x + 35, x - 70

90, 125, 20

Answer:

7.2 *10⁻⁵

Step-by-step explanation:

Given the diameter of the hair expressed as 0.000072, we are to express it in scientific notation.

The standard form of scientific notation is expressed as;

A * 10ⁿ

A is a value from 1 to 9

n is any integer.

Rewriting 0.000072 in this form, we will need to shift the decimal point to the front 5 times to have;

0.000072 = 7.2 *10⁻⁵ where;

A = 7.2 and n = -5

Note that the power is a negative value since the value is less than 1.

Fraction of composite numbers = 6/10

Fraction of prime numbers = 4/10

Step-by-step explanation:

A composite number can be defined as a positive integer that will be formed when we multiply two smaller positive integers. It can also be said to be a positive integer that has at least one divisor of which 1 and itself are not included.

Thus, it means that the set of numbers given to us which is;

(11, 12, 13, 14, 15, 16, 17, 18, 19, 20), the composite numbers are;

12, 14, 15, 16, 18, 20

This is because each of them have at least one divisor that is neither itself or 1.

Thus, we have 6 out of the 10 numbers as composite.

Fraction of composite numbers = 6/10

Now, a prime number is a number that are only divisible by itself and 1.

Thus,from the given set, the prime numbers are; 11, 13, 17 & 19

We have 4 out of 10 numbers as prime numbers.

Thus, fraction of prime numbers = 4/10

Answer:

$16

Step-by-step explanation:

To find the cost per square foot we have to solve the given equation for x:

6.4x - 3.7x = 43.2

2.7x = 43.2

Divide both sides of the equation by 2.7 to isolate the x:

2.7x/2.7 = 43.2/2.7

x = 16

The sheet metal costs $16 per square foot.

Answer:

3x^22−x^2+3

Step-by-step explanation:

Let's simplify step-by-step.

3x^22+2x+4−(x2+2x+1)

Distribute the Negative Sign:

=3x^22+2x+4+−1(x2+2x+1)

=3x^22+2x+4+−1x2+−1(2x)+(−1)(1)

=3x&22+2x+4+−x2+−2x+−1

Combine Like Terms:

=3x22+2x+4+−x2+−2x+−1

=(3x22)+(−x2)+(2x+−2x)+(4+−1)
