7 0

Answer:

<em>2.5</em>

Step-by-step explanation:

y2 - y1 = top

x2 - x1 = bottom

<em>y2 = -5</em>

<em>y1 = -7.5</em>

<em />

<em>x2 = -2</em>

<em>x1 = -3</em>

<em />

<em />

-5-(-7.5) = 2.5

-2-(-3) = 1

2.5 over 1 = 2.5

Abraham has visited country somebody he has a cold or visiting at least 50 countries he plans to choose a school by visiting fiv
Ipatiy [6.2K]

<em>Question:</em>

<em>Abraham has visited at least 50 countries; he plans to visit five new countries per year (Y) for the next several years. Which inequality and solution shows the amount of years they will take for Abraham to meet his goal.</em>

Answer:

Countries \geq 50 + 5y

y \leq 29

Step-by-step explanation:

Given

Countries = 50 ------ at least

Yearly =5

Required

Represent as an inequality

"at least" means \geq

So the countries he has visited can be represented as thus;

Countries \geq 50

If

1 year = 5 countries

y years would be 5y countries

So, in y years; he'd have visited

Countries \geq 50 + 5y

To determine the value of y.

We have that

Countries = 195 <em>in the world</em>

<em>Substitute 195 for Countries</em>

195 \geq 50 + 5y

<em>Collect Like Terms</em>

195 - 50 \geq 5y

145 \geq 5y

<em>Divide through by 5</em>

145/5 \geq y

29 \geq y

<em>Reorder</em>

y \leq 29

This means that; he'll visit all countries in at most 29 years' time

Jake said he can find 630 ÷ 10 by taking the 0 off of 630 to get 63.
Colt1911 [192]

Answer:

Jake is incorrect with his methodology for solving these problems

Step-by-step explanation:

Jake is incorrect with his methodology for solving these problems. This is because dividing a number by 10 requires moving the decimal point one digit to the left. When dividing 630 by 10, removing the zero works because by moving the decimal one digit to the left we would simply drop the zero and the decimal would not be needed leaving the answer as 63. However, this does not work on numbers that already have a decimal such as 35.270. This number divided by 10 would be 3.527 but simply removing the 0 like Jake states would give us the incorrect answer of 35.27
