D.) 7(8 - X) - 5 = 40
let X = unknown number
eigth minus a number is 8 - x. since the product is seven and eight minus a number then 7 * [8-x] or 7(8-5).
40 is its equivalent when the product is decreased by 5; therefore, 7(8-x) - 5 = 40.
Known facts
8w - 2p = 8(6) - 2(-5) = 48 + 10 = 58
Answer: 58
Hope that helps!
Answer:
yes
Step-by-step explanation:
yes
Answer:
x=2
Step-by-step explanation:
x^3=8
x=2 (take the cubed root of both sides)
This can be solved by adding 8 to both sides, then taking the cubed root of both sides
Step-by-step explanation:
Use the sine and cosine trig functions
21) cos(52)=13/x
x=13/cos(52)
x=21.1
22) sin(75)=6/x
x=6/sin(75)
x=6.2
