Ok the answer is -5 less than 9 which is true lol
Anyways here’s how I got the answer
-5+7+2x-13 less than 9
Combine like terms in this case it’s -5 and 2, and the other is 7 and -13
-5+2= -3
7-13= -6
Ok now that that’s done here’s the next step
-3x-6 less than 9 solve it
-3x-6 < 9
+6< +6
-3x < 15
Now from there you divide then so
-3x/3 cancels out, and 15/-3 = -5
X=-5
And so -5<9 :) hope this helped!! I will also include a picture of my work (please exult messiness lol)
Answer:
-2 is a solution
Step-by-step explanation:
-2-5<8
-7<8
Answer:
x = 60° (Alternate angles)
Step-by-step explanation:
a) x = 60°
b) Reason: Alternate angles
13.) A=9cm^2
If the area is l•h, and there are 9 cubic squares, that means that the length of each side on the square is 3cm, each square on it equals 1cm.
14.) V=27cm^3
If the volume is l•w•h, then we find the third power square root of 27, so 3•3=9•3=27, the answer is 3cm for the length, width, and height.
15.) V=4,913cm^3
If volume is l•w•h, then what number when raised to the third power equals 4913? The answer is 17, since 17•17=289•17=4913. So the length is 17cm
16.)V=216cm^3
If volume is l•w•h, then what number when raised to the third power equals 216? The answer is 6, since 6•6=36•6=216.
17.)A=121
Is area is l•w, then what number raised to the second power equals 121? The answer is 11, since 11•11=121. Therefore it WILL NOT fit a car with a length of 13ft.
18.)A=141
If area is l•w, then what number raised to the second power equals 141? The answer is 12, since 11.87•11.87=141 (answer was rounded to nearest whole number) meaning that she will need 12ft of fence to enclose her garden.
