Answer:

x= -8

Step-by-step explanation:

Answer:

[tex]17 + 5x = - 23 \\ 5x = - 23 - 17 \\ 5x =-4 0 \\ x = \frac{ - 40}{5} \\ \boxed{x = - 8}[/tex]

Answer:

D

Step-by-step explanation:

Using the converse of Pythagoras' identity.

If the square of the longest side is equal to the sum of the squares on the other two sides then the triangle is right.

longest side = 12 and 12² = 144

5² + 8² = 25 + 64 = 89

Since 5² + 8² ≠ 12² , then triangle is not right → D

Answer:

B did it on edg

Step-by-step explanation:

The expression that shows how Joshua could use place value to break up this problem and solve it is:

(30 + 8) x (10 + 2)

Option B is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

38 x 12

This can be written in place value as,

38 = 3 tens and 8 ones

12 = 1 tens and 2 ones

So,

38 = 30 + 8

12 = 10 + 2

Thus,

The expression used is (30 + 8) x (10 + 2)

Answer:

The measure of angle x is 25 degrees.

Step-by-step explanation:

Since triangle ABC is an isosceles triangle, the measure of angle BAC is equal to the measure of angle ACB. Angle ABC = 80 degrees, leaving 100 degrees to be divided equally for the measures of the other two angles. Now that you know that angle ACB = 50 degrees, you can calculate the value of angle ACD and determine that angle ACD = 130 degrees. Triangle ACD is also an isosceles triangle, and the two equal legs are AC and CD. Since angle ACD = 130 degrees, the other two angles have a total of 50 degrees. Splitting the 50 degrees equally between the two angles gives you 25 degrees as the value of angle CAD, which is labeled "x."

To solve this question, we need to understand the concept of midpoint.

Doing this, we get that x is equals to 4 miles., and we find it using each of these three ways:

Segment:

C is the midpoint of the segment AB, which means that:

The distance of the initial point A to the midpoint C is the same as the distance of the midpoint C to the final point B.

[tex]AC = CB[/tex]

The distance of the midpoint to one of the endpoints is half the total distance, that is:

[tex]AC = \frac{AB}{2}[/tex]

[tex]CB = \frac{AB}{2}[/tex]

Solution:

We have to solve for x, considering one of the three relations.

Considering:

[tex]AC = 4x, CB = 12 + x[/tex]

[tex]AC = CB[/tex]

[tex]4x = 12 + x[/tex]

[tex]4x - x = 12[/tex]

[tex]3x = 12[/tex]

[tex]x = \frac{12}{3}[/tex]

[tex]x = 4[/tex]

The solution for x is x = 4 miles.

Answer:

First, find the cost function of DoItRight Housekeeping:

The y-intercept(b), representing the initial cost, can be calculated by substituting in values to the function:

[tex]f(x)=12x+b\\26=12(1.5)+b\\b=26-18=8[/tex]

Therefore, the function for two companies are:

When comparing the two functions, it's shown how CleanIt has a greater y-intercept than DoltRight, meaning that CleanIt has a greater initial cost than DotRight. The y-intercept is when the graph intercepts the y-axis, therefore, the coordinates there would be (0, y-value), which, in this case for CleanIt company, will be (0, 16). While CleanIt has a greater y-intercept(initial cost), DoItRight has a greater slope, meaning they cost more per hour.

Step-by-step explanation:

LCM of 70, 60, and 50?

First, find the prime factorization of each number.

70 = 2 * 5 * 7

60 = 2^2 * 3 * 5

50 = 2 * 5^2

The LCM is the product of some of the factors above. These are the factors you need to multiply together.

Choose factors that are common with the highest exponent and also factors that are not common.

Common factors: There is a 2, a 2^2, and a 2. Use the 2^2.

There is a 3. Use it.

There is a 5 and a 5^2. Use the 5^2.

There is a 7. Use it.

LCM = 2^2 * 3 * 5^2 * 7

LCM = 2100

Answers and step-by-step explanation:

First, we add up all the totals for the box tops. This would be 3,750+2,301+1855 which totals to 7,906. Then, we take each individual box top value and divide it by 7,906 to get the fractions. For Mr. Aceves' class, the percentage is 47%, for Mrs. Baca's class, the percentage is 29% and finally for Mr. Canyon's class, the percentage is roughly 24%. This would mean that Mr. Aceves' class should get $282, Mrs. Baca's class should get roughly $174, and Mr. Canyon's class should receive $144.

(110011)2 = (51)10

Step by step solution

Step 1: Write down the binary number:

110011

Step 2: Multiply each digit of the binary number by the corresponding power of two:

1x25 + 1x24 + 0x23 + 0x22 + 1x21 + 1x20

Step 3: Solve the powers:

1x32 + 1x16 + 0x8 + 0x4 + 1x2 + 1x1 = 32 + 16 + 0 + 0 + 2 + 1

Step 4: Add up the numbers written above:

32 + 16 + 0 + 0 + 2 + 1 = 51.

So, 51 is the decimal equivalent of the binary number 110011.

Step-by-step explanation:

Assuming DE is an angle bisector , then it divides the opposite side into segments that are proportional to the other 2 sides, that is

[tex]\frac{HD}{DG}[/tex] = [tex]\frac{EH}{EG}[/tex] , substitute values

[tex]\frac{x+4}{58}[/tex] = [tex]\frac{55}{63.8}[/tex] ( cross- multiply )

63.8(x + 4) = 3190 ( divide both sides by 63.8 )

x + 4 = 50 ( subtract 4 from both sides )

x = 46
