Answer:

False, also the typed version of this problem does not actually use the expression in the accompanying screenshot. That clearly reads as x + 5

Step-by-step explanation:

The problem, assuming x = 4 can be read as 4 + 5. Simple math dictates this would equal nine and as there is no negative to either number nor a negative outside of the lines surrounding the problem itself the solution is simple and leads to a false answer.

The answer is going to be false because if you subtract 51 from both sides, x will equal -60

Compare the numbers with<br> &gt;, &lt;, =<br> - 3.5 ____ 2.8<br> 7.4 ____ - 9
labwork [276]

Answer:

-3.5 <u>   <   </u> 2.8

7.4 <u>   >   </u> -9

Step-by-step explanation:

If you have a negative number and a positive number the <em>positive number is always greater.</em>

When you have a negative number and another negative, <em>the smallest number is greater. </em>

For example: -2.5 <u>       </u> -3.7

-2.5 is greater than -3.7 because it is <em>less</em> negative.

-2.5 <u>   >   </u> -3.7

When you have a positive number and a positive number, <em>the biggest number is greater.</em>

For example: 8.3 <u>       </u> 4.2

8.3 is greater than 4.2 because it is a <em>bigger number</em>.

8.3 <u>   >   </u> 4.2

Find the equation of the line that goes through ( 2, 4 ) and ( 4, 6 ).
Mrrafil [7]

Answer:

y=x+2

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(6-4)/(4-2)

y-y1=m(x-x1)

y-4=1(x-2)

y=x-2+4

y=x+2

2/3 of a yard would be 2 feet

4.5 yards = 13.5 feet
13.5-2 = 11.5 feet

11.5 feet = 3.83 yards

therefore at least 11.5 feet or 3.83 yards must be purchased
