Answer:
Negative 4 n + 8 + 9 n minus 2 and 5 n + 6
Step-by-step explanation:
3v + 5 - (9v + 2)
3v + 5 - 9v -2 = -6v + 3
-6v + 6
(NO)
-6n + 3 - (2n + 2)
-6n + 3 - 2n - 4 = -8n - 1
-8n + 6
(NO)
-4n + 8 + 9n - 2 = 5n + 6
5n + 6
(YES)
X=40 degree is the correct answer
Answer:
5.6
Step-by-step explanation:
3.4-2.3=1.1
2.3+1.1=3.4
3.4+1.1=4.5
4.5+1.1=5.6
Answer:
1 * 5 = 5cm
3 * 5 = 15cm
2 * 5 = 10cm
Step-by-step explanation:
1+3+2 = 6
then do 30 / 6 = 5 to find one part of the ratio
1 * 5 = 5
3 * 5 = 15
2 * 5 = 10
Answer:
y = 112
Step-by-step explanation:
If y varies directly as the square of x
mathematically;
y ∝ x²
y = kx² where 'k' is the constant of proportionality
let u know the value of k for this equation by making k the subject of the formular from y = kx²
divide both sides by x²
k = y / x²
given that y = 567 x = 9
k = 567/(9)²
k = 567/81
k = 7
now to get the value of y when x = 4
from the equation conneting x, y,
y = kx²
y = 7 × (4)²
y = 7 × 16
y = 112
