Answer:
84+(x+9)=180
Step-by-step explanation:
84º+(x+9)º = 180º, so x+93 = 180, so x=87. Hope this helps!
You could also use a ruler or some other measuring device for (2). You can also draw a picture of a circle with the denominator as the slices, and the numerator as the shaded areas, then compare both fractions together for (3).
1+3+6=10
40=10 units
diidde by 10
4=1unit
4 times 1=4
4 times 3=12
4 times 6=24
they paid $4, $12 and $24
Answer:
(n + 6)(n - 2)
Step-by-step explanation:
Given
n² + 4n - 12
Consider the factors of the constant term (- 12) which sum to give the coefficient of the n- term (+ 4)
The factors are + 6 and - 2 , since
6 × - 2 = - 12 and 6 - 2 = + 4
Then
n² + 4n - 12 = (n + 6)(n - 2) ← in factored form
Answer:
The answer should be 120.
Step-by-step explanation:
30% of 400 = 120 cats
