Answer:
u = 6/35
Step-by-step explanation:
w = k * u
w = ku
Where
k = constant of proportionality
if w=5 when u= 3
w = ku
5 = k * 3
5 = 3k
k = 5/3
find u when w is =2/7
w = ku
2/7 = 5/3 * U
2/7 = 5/3u
u = 2/7 ÷ 5/3
= 2/7 × 3/5
= (2*3)/(7*5)
= 6/35
u = 6/35

Explain how you know that 88 is a solution to the equation 1/8x =11 by completing the sentences:
The word "solution" means . . .
88 is a solution to 1/8x=11 because . . .
Answer/Step-by-step explanation:
✔️The word solution means the value of the unknown variable, x. This means, when the value of x is substituted into the equation, the equation becomes balance as the value on the left equals the value on the right.
✔️88 is a solution to ⅛x = 11 because:
if we substitute x for 88 into the equation, both sides would be equal.
Thus:
⅛×88 = 11
11 = 11
5.6 x 2.1 x 6.6 = 77.616 2 significant figures would be 78 cm³ 2 decimal places would be 77.62 cm³
Answer: Yes
Step-by-step explanation: A triangle can be formed because A+B>C
A and B are 2.9 and 4.8
Since those numbers have the least value
I added both and found that A and B are equal to 7.7
7.7>7.4
These sides could form a triangle
