-3+(5×7)
Step 2:you multiply the variables in the bracket to get close to the answer
-3+(35)
Step 3:You notice the signs and multiply them together to get the answer
-3+35=32
Answer:
The solution to the given inequality
Step-by-step explanation:
Given inequality
⇒ -1≤ 7× 3h
⇒ -1 ≤ 21 h
⇒ 21 h ≥ -1
⇒
Answer:
57.5
Step-by-step explanation:
The constant of proportionality is "k" in the equation ...
y = kx
It can be found from values of x and y using ...
k = y/x
For the given values, it is ...
k = (287.5 mi)/(5 h) = 57.5 mi/h
The constant of proportionality relating miles to hours is 57.5.
Remark
You need to start with three facts.
x and y are complements which means that x + y = 90
Sin(x) = cos(90 - x)
<CPN = <DPN Definition of a bisector.
From the 3 facts above, we can gather than
CPN + y = 90
Therefore the cos of CPN = Sin(y)
i) x²
ii) (x-10)²
b) (x-10)² = x² - 20x + 100
c) (30-10)² = 400 cm²
d) (x-10)² = 144 => x-10 = √144 => x = 12 + 10 = 22 cm
