6x + 8 = 50 solve equation

Answers

The solution of expression '6x + 8 = 50' by combining like terms with applying the operations would be, x = 7

Given that,

The equation is,

6x + 8 = 50

Used the concept of expression to simplify by combining like terms with applying the operations addition, subtraction, etc.

Here, the equation is,

6x + 8 = 50

Subtract 8 on both sides,

6x = 50 - 8

6x = 42

Divide 6 on both sides,

x = 42/6

x = 7

Therefore, the solution of expression is x = 7.

In 2004, there were approximately 275 students in the Delaware High School band. In 2010, that number increased to 305. Find the annual rate of change in the number of students in the band.

Answers

305-275=30
Since there is a difference of 6 yaers between 2010 and 2004, you devide 30 by 6 which equals to five. Therefore each year there was an increase of 5 students in the band.

Ebba is buying bulk fabric and shopping for the best deal. Drag the fabric in order from the least to the greatest unit cost in dollars per square yard.

Answers

Answer:

From least to greatest in cost is Red, Brown, Purple, Silver.

Step-by-step explanation:

Ebba is buying bulk fabric and shopping for best deal, in order to calculate best deals of fabric we calculate per square yard of each fabric.

Purple : 6.5 square yard = $6.25

Therefore 1 square yard = 6.25 ÷ 6.5 = $0.96

Red : 4 square yard = $3.00

Therefore 1 square yard = 3.00 ÷ 4 = $0.75

Brown : 8.5 square yard = $8.10

Therefore 1 square yard = 8.10 ÷ 8.5 = $0.95

Silver : 6 square yard = $7.20  

Therefore 1 square yard = 1.20 ÷ 6 = $1.20

Now we arrange the fabric in order from the least to the greatest unit cost in dollars per square yard.

Red, Brown, Purple and Silver.

The answer is Red=0.75, Brown=0.95, Purple=0.96, Silver=1.20

Samuel will arrive at the airport on the first plane after 10 A.M. Airplanes arrive every 50 minutes beginning at 6 A.M. When will Samuel's plane arrive?

Answers

The plane Samuel's will arrive at 10:10 AM if Samuel arrives at the airport on the first plane after 10 AM, Airplanes arrive every 50 minutes beginning at 6 AM.

What is multiplication?

One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.

Given:

Samuel will arrive at the airport on the first plane after 10 A.M,

Airplanes arrive every 50 minutes beginning at 6 A.M.,

Calculate the time of Samuel's plane as shown below,

The total time = 10 - 6 = 4 hours

The total time = 4 × 60 = 240 minutes

If the plane is coming in every 50 minutes, then the 5th plane will come at 5 × 50 = 250 minutes

Thus, the plane Samuel's will arrive at 10:10 AM.

Felipe bought 3/4 of a pound of American cheese at the deli. She used 1/2 of the cheese to make sandwiches. How much cheese did she use?

Answers

She used 3/8 of the cheese. Since she used 1/2 of 3/4, you multiply 3/4 times 1/2. If you multiply straight across, the answer should be 3/8. If you need further explanation, just ask! Hope this helps! =D :D
The answer is 2/4 because 2 is half of 4.
