Answer:
x <6
Step-by-step explanation:
5x-9 < 21
Add 9 to each side
5x-9+9 < 21+9
5x< 30
Divide each side by 5
5x/5 <30/5
x <6
You would just multiply $0.22 8 times then add the $0.54 to it and you get $2.30
Answer:
20
Step-by-step explanation
not sure but looks like you need help as fast as possible here my answer the way i thought about is you have 70 degree angle and y looks like a right angle which = 90 degree
x = 180 - 70+90
x = 180 - 160
x = 20
Answer:
172 ft
Step-by-step explanation:
Due south and due east form a 90-degree angle.
Her path is a right triangle. The 60 ft and 40 ft distances are the legs of the right triangle. We can use the Pythagorean theorem to find the hypotenuse. Then we add the lengths of the three sides to find the total distance she traveled which is the perimeter of the right triangle.
a^2 + b^2 = c^2
(40 ft)^2 + (60 ft)^2 = c^2
1600 ft^2 + 3600 ft^2 = c^2
c^2 = 5200 ft^2
c = 72 ft
perimeter = a + b + c = 40 ft + 60 ft + 72 ft = 172 ft
Answer:
15000
Step-by-step explanation:
In 15476, 5 is the place value of thousand. For rounding it to nearest 1000, check the next digit to 5. It is 4, which is less than 5. So, 15476 rounded to 1000 is 15000
