Answer:
14
Step-by-step explanation:
perimeter = sum of all sides
so 75- (15+10+27+9)
= 75- 61
= 14
Answer:
9(p + 4)
Step-by-step explanation:
One of the unknown variable is p.
First of all, we know that the number is 9 times as big (multiplication) as the new number obtained through the addition of four to p i.e (p + 4).
Translating the word problem into an algebraic expression, we have;
9 * (p + 4) = 9(p + 4)
Simplifying further, we have;
9p + 36
Answer:
C
d=(0.6)(30)
Step-by-step explanation:
Let the distance run in 30 minutes be d
Given the zebra can run 0.6 miles in one minute
That’s
0.6mile = 1 minute
How far can the zebra run in 30 minutes
That’s
d miles = 30 minutes
Therefore, we now have
0.6mile = 1 minute
d mile = 30 minutes
Cross multiply
d x 1 = 0.6 x 30
d = 0.6 x 30
Or
d = (0.6)(30)
Answer:
60 miles
Step-by-step explanation:
miles that Sophia drove = 3/5 x 100 = 60 miles
Answer:
see explanation
Step-by-step explanation:
To find the x- intercepts let f(x) = 0, that is
x² - 3x - 4 = 0
Consider the factors of the constant term (- 4) which sum to give the coefficient of the x- term (- 3)
The factors are - 4 and + 1, since
- 4 × 1 = - 4 and - 4 + 1 = - 3, thus
(x - 4)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 1 = 0 ⇒ x = - 1
x- intercepts are (- 1, 0 ) and (4, 0 )
