Answer:
x ≤ -15
Step-by-step explanation:
-x / 3 ≥ 5
multiply by 3
-x ≥ 15
add x to both sides and subtract 15 from both sides
-15 ≥ x or x ≤ -15
Answer:
5700
Step-by-step explanation:
step 1 Address the formula, input parameters & values.
Input parameters & values:
The number series 2, 4, 6, 8, 10, 12, . . . . , 150.
The first term a = 2
The common difference d = 2
Total number of terms n = 75
step 2 apply the input parameter values in the AP formula
Sum = n/2 x (a + Tn)
= 75/2 x (2 + 150)
= (75 x 152)/ 2
= 11400/2
2 + 4 + 6 + 8 + 10 + 12 + . . . . + 150 = 5700
Therefore, 5700 is the sum of first 75 even numbers.
Answer:
A = 27π cm² or about 84.8 cm²
Step-by-step explanation:
Area of a full circle is πR²
As there are four right angles making up a 360° turn, and the missing piece is one of those four, there are ¾ of a circle remaing
A = ¾πR² = ¾π6² = 27π cm² or about 84.8 cm²
The heavy suitcase.
A small car would still weigh quite a lot, a tablet would weigh a lot less than that, and a watermelon is around 2kg (depends).
Step-by-step explanation:
Let's represent Aaron's age with x and
Charlene's age with x+8
x+x+8=44
2x+8=44
2x=44-8
2x=36
x=36÷2
x=18
Aaron is 18 years old.
While Charlene is 18+8=26 years old.
