Answer:
x = 7
angle A = 7(7) + 4 = 49 + 4 = 53°
angle B = 4(7) + 9 = 28 + 9 = 37°
Step-by-step explanation:
m ∠A + m ∠B = 90° Complementary angles sum = 90°
7x + 4 + 4x + 9 = 90
11x + 13 = 90
11x = 77
x = 7
angle A = 7(7) + 4 = 49 + 4 = 53°
angle B = 4(7) + 9 = 28 + 9 = 37°
Check = angle A + angle B = 90° checked
Answer:
circumference TO the diameter
Step-by-step explanation:
circumference of the circle TO the diameter of the circle
Answer: 706 grams
Step-by-step explanation:
s(m) = km
So 6000 = 8.5m
Divide both sides by 8.5 to isolate m
6000/8.5 = 8.5m/8.5
705.88 = m
m = 706 (rounding up)
Answer:
2x+6≥6x−4-->-4x≥-10-->x≤2.5
4x>-1 --> x>1/4
Step-by-step explanation:
Answer:
Inequality is
and value of x>10.
Step-by-step explanation:
Given : Adam is ordering pizza for a company party that he needs to have catered.
Company A charges $8 for each pizza and a delivery/set-up fee of $45. Company B charges $12 for each pizza and a delivery/set-up fee of $5.
To find : Which inequality can be used to find x, the least number of pizzas that can be ordered so that the total charge for Company A is less than the total charge for Company B?
Solution : Let x be the number of pizza
Company A charges $8 for each pizza and a delivery/set-up fee of $45.
Total charge of Company A is 
Company B charges $12 for each pizza and a delivery/set-up fee of $5.
Total charge of Company B is 
The total charge for Company A is less than the total charge for Company B
i.e, Inequality form 




or x> 10
Therefore, Inequality is
and value of x>10.
