Answer:
Step-by-step explanation:
y ∞ x/m
y = kx/m
Where k is the constant of proportionality
A. k = ym/x
y=5 when x=7 and m=4
k = (5×4)/7
k = 20/7
y = 20x/7m
B)the value of when x=2and m=2
y = 20x/7m
y = (20×2)/(7×2)
y = 40/14
y = 20/7
y = 2 6/7
C. The value of m when y=2 and x=4
y = 20x/7m
7ym = 20x
m = 20x/7y
m = (20×4)/(7×2)
m = 80/14
m = 40/7
m = 5 5/7
90
3x+x-15+2x+15=180
6x=180
Divide each side by 6
X= 30
Now go back to each angle and substitute 30 for x
(3 x 30)= 90
(30-15)= 15
(2(30)+15)=75
Answer:
Option C.
Step-by-step explanation:
The given expression is
Step 1: Rewrite the given expression.
Step 2: Using distributive property we get
![[\because a(b+c)=ab+ac]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%28b%2Bc%29%3Dab%2Bac%5D)
Step 3: On multiplication, we get
Step 4: On addition, we get
In step 2, Calvin confused the multiplication and addition signs
Therefore, the correct option is C.
This has to do with place value.
0.135.....the last digit (5) is in the thousandths place....so put it over 1000.
135/1000 reduces to 27/200
Answer:
When x = 11, y = 1331
Step-by-step explanation:
y = x³ according to the table
Hence,
when x = 11,
y = 11³
= 1331
