Answer:
1) x ≤ 30
2) 5x + 2x ≥ 14
3) x × y ≤ 4
4) y - 5 < 20
Step-by-step explanation:
At most means " no more than, " " less than or equal to, " or " not greater than"
The math symbol that you will use for at most is ≤
At least means " no less than " or " greater than or equal to "
The math symbol that you will use for at least is ≥
Answer:
275.63 mm^2
Step-by-step explanation:
The measurements of the pyramids are
Edge length: 10
Egde width: 8.66 (because 10x8.66/2 = 43.3)
Height: 9
To find the surface area, use this formula, and you will get 275.63:
Answer:
The proportion of red candies is 60/100.
Step-by-step explanation:
Given that sixty out of every 100 pieces of candy is red, to determine which indicates the proportion of red candies, the following calculation must be performed:
60 red candies out of 100 total candies
60/100
Therefore, the ratio of red candies is 60/100.
Answer: y=3 x=4
Step-by-step explanation:
Its a rectangle so the 2 horizontal sides are even and the vertical sides are even. So, since one side is 10, the other side has to be 10. So, 2y+4 = 10. subtract 4 from each side getting 2y = 6. divide by 2 to get the y by its self and you get y = 3.
For the horizontal side, 10 + 2x = 18. subtract 10 from each side. 2x = 8 divide by 2. x = 4
Answer:
x
=
21/2
Step-by-step explanation:
Move all terms not containing x to the right side of the equation.
3x=x+21
Move all terms containing x to the left side of the equation.
2x=21
Divide each term by
2
and simplify.
x
=
21/2
