Answer:
8 intersections
Step-by-step explanation:
Miss Stevens drove through a total of 36 intersections on her way home from work last week.
At four of every 16 intersections Miss Stevens had to stop for a red light before she could drive through .
This is calculated as:
36 intersections ÷ 16 intersections
= 2 4/16
= 2 1/4
At four of every 16 intersections Miss Stevens had to stop for a red light before she could drive through .
4 of every 16 intersections = stop for a red light
Hence:
16/4 = 4 intersections
Hence: 4 intersections = 1 stop for a read
The number of intersections that Miss Stevens had to stop for a red light is:
2 × 4 intersections = 8 intersections
2 and 2/3 + 4 and 3/4 is equal to 7 and 5/12
Answer:
x = 
Step-by-step explanation:
Given
5xy + a = c ( isolate 5xy by subtracting a from both sides )
5xy = c - a ( isolate x by dividing both sides by 5y )
x =
Answer:
x² - 5x + 4
Step-by-step explanation:
note that (p - q)(x) = p(x) - q(x), thus
p(x) - q(x)
= x² - 1 - 5(x - 1) ← distribute parenthesis by - 5
= x² - 1 - 5x + 5 ← collect like terms
= x² - 5x + 4
