Answer:
x=45/6
Step-by-step explanation:
2+7y=8. 7y=8-2. <u>7</u><u>y</u><u>=</u><u>6</u>
7=7. y=6\7
insert the value of y in the second equation. 5x-7y=16
5x-7(6/7)=16
5x-49\6=16
collect the liketerms together
5x=16+49/6
5x=145/6(divide both sides by 5)
x=29/6
x=45/6
<em><u>f</u></em><em><u>u</u></em><em><u>r</u></em><em><u>t</u></em><em><u>h</u></em><em><u>e</u></em><em><u>r</u></em><em><u>.</u></em>
<em><u> </u></em>confirm if the 2 in the second equation has an X coz the questions are normally set with both equations having both values x and y
The number of years based on the equation is 24 years.
<h3>How to illustrate the information?</h3>
The information is incomplete. An overview will be given. Let the income equation be represented as I = 60 + 10x where x represents the years taken.
Therefore i = 60 + 10x
60 + 10x = 300
10x = 300 - 60
10x = 240
x = 240/10
x = 24

If two similar figures have side lengths that differ by a factor of x, then their area will be different by a factor x².
The side length of Hunter's square of compost is 4 times larger than the 6 by 6 square. The area will be 4², or 16, times larger than the area of the 6 by 6 square.
Multiply 16 with 500 beetles.
Hunter can have 8000 beetles with his square of compost.
Answer:
1
Step-by-step explanation:
= -2 + 7 + (-4)
=5+(-4). (because positive and negative form negative)
=5-4
=1
87-10= 77 F
the temperature dropped to 77 Fthat night
