Answer:
102
Step-by-step explanation:
Since 2 + 8 = 10, then the cube root of 5x+2 = 8
Since 8×8×8=512, then 5x+2=512
5x=510, so x=102
To find this, you'd just add 13 to -2. So -2 + 13 = 11. So the starting temperature was 11 degrees.
Answer:
The answer to your question is Area = 3240 ft² or Area = 360 yd²
Step-by-step explanation:
Data
length = 30 yd
width = 36 ft
Area = ? ft²
Area = ? yd²
Process
1.- Convert the units
1 yd --------------------- 3ft
30 yd ------------------ x
x = (30 x 3)/1
x = 90 ft
1 yd ------------------- 3 ft
x ------------------- 36 ft
x = (36 x 1) / 3
x = 12 yd
2.- Calculate the area of the rectangle in ft²
Area = length x width
-Substitution
Area = 90 x 36
= 3240 ft²
3.- Calculate the area in yd²
Area = 30 x 12
= 360 yd²
A conditional statement is always true backwards and forwards
Answer:
n=2
Step-by-step explanation:
4(5n-7)=10+2
1) First, distribute (multiply out 4)
20n-28=10+2
2) Combine like terms (add 10 and 2)
20n-28=12
3) Isolate the variable (Add 28 to 12)
20n=40
4) Isolate the variable (Divide by 20)
n=2
