Answer:
−9.333
Step-by-step explanation:
(1): "6.75" was replaced by "(675/100)"
(675/100)+3/8*x-((13)*1/4)=0
Simplify 1/4
675 3 1
(———+(—•x))-(13•—) = 0

Answer:
45
Step-by-step explanation:
Since the values are relatively small substitute i = 1 to 5 into 3i and sum
(3 × 1) + (3 × 2) + (3 × 3) + (3 × 4) + (3 × 5)
= 3 + 6 + 9 + 12 + 15
= 45
Answer:
4x²+3x-7 is the answer
Step-by-step explanation:
=(4x²-2x)+(5x-7)
opening brackets
=4x²-2x+5x-7
=4x²+3x-7
i hope this will help you :)
Answer:
y = 45x miles
Step-by-step explanation:
Speed is the rate of change of distance with time. Mathematically,
speed = distance/time
Given that Darla travels at a constant speed of 45 miles per hour and for y miles, it takes her x hours then
45 = y/x
multiply both sides by x
45x = y
then the number of miles (y) Darla can drive in x hours
y = 45x (in miles)
