Answer:

The answer top your question is: 1/2, 3/2, 5/2 and 7/2

Step-by-step explanation:

Data

4 consecutive numbers that add up to 8

First number = n

2nd number = n + 1

3rd number = n + 2

4th number = n + 3

Now, add them up n + n + 1 + n + 2 + n + 3 = 8

Simplify like terms

4n + 6 = 8

4n = 8 - 6

4n = 2

n = 2/4 = 1/2

First number = n = 1/2

2nd number = n + 1 = 1/2 + 1 = 3/2

3rd number = n + 2 = 1/2 + 2 = 5/2

4th number = n + 3 = 1/2 + 3 = 7/2

Answer: d = 4t - 10

====================================================

Each side of the square picture frame is t centimeters long. The perimeter is t+t+t+t = 4*t centimeters long, which is just the entire distance around the frame. If we had the perfect amount of ribbon, then d = 4*t would be the end of the problem; however, we're 10 cm too short meaning that d is too small and it's actually d = 4*t - 10

For example, let's say that t = 12 meaning that the perimeter is 4*t = 4*12 = 48 cm. This would mean we have d = 4*t-10 = 4*12-10 = 48-10 = 38 cm of ribbon, and we're 10 cm too short (comparing 38 to 48).

note: d = 4t - 10 can be written as d = 4*t - 10

A city with a population of 800,000 has been growing at a rate of 7% per year. If this rate continues, find the population of th

Contact [7]

Answer:

Step-by-step explanation:

Population(pop) = 800,000 people

Growth rate=7℅

Pop growth in a year= ((100+7)÷100) × 800000 =856000people

Pop in 20 years = 856000×20

=17,120,000 people

Please help me answer these!!! Thanks :)

-2-(+7) is the same thing at -2-7 which is -9

$-3 \frac{2}{7} -(- \frac{5}{7} )$ is the same thing as $(-3 \frac{2}{7}) + (\frac{5}{7})$ which is $- \frac{18}{7}$ or $-2 \frac{4}{7}$

Last but not least the last one is the Associative Property based on definition listed below :)
Associative Property:<span> When three or more numbers are added, the sum is the same regardless of the grouping of the addends. For example (2 + 3) + 4 = 2 + (3 + 4)</span>

Choose the correct simplification of f^9 h^23/f^3 h^17

Tanzania [10]

Answer:

f6h40

Step-by-step explanation:

Step 1 :

h23

Simplify ———

Equation at the end of step 1 :

h23

((f9) • ———) • h17

Step 2 :

Multiplying exponential expressions :

2.1 h23 multiplied by h17 = h(23 + 17) = h40

Final result :

f6h40
