Answer:
x = 4
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, thus
7x - 4 = 24 ( add 4 to both sides )
7x = 28 ( divide both sides by 7 )
x = 4
Answer:B 55
Step-by-step explanation:
Answer: Crickets make 172 chirps/min at 80 degrees Fahrenheit
Step-by-step explanation:
Step 1
Using the point slope formulae for Linear functions , we have that
y - y1 = m(x - x1)
where x and y are two points representing the temperature and chirps /min respectively
And
m= slope
Step 2 : Finding the slope , m
where x1=60
y1=92
x2= 75
y2=152
m= (y2-y1)/ (x2-x1)
= (152- 92)/(75-60)
=60/15 =4
Bringing down the point/slope formula and imputing the known values to find our equation to show the relationship cricket make per minute and the temperature
y - y1 = m(x - x1)
y - 92= 4(x - 60)
y - 92 = 4x -240
y = 4x - 240 + 92
y = 4x - 148
Step 3
To find the number of chirps be per minute (y) if the temperature is 80 degrees Fahrenheit( x)
y = 4(80) - 160
y = 320 - 148
y = 172 chirps/min at 80 degrees Fahrenheit
ANSWER:
The answer would be C. 54/7
EXPLANATION:
Multiply 9* 6/7 = 9x6/1x7 = 54/7
Multiply both nominators and denominators
Result to keeping the lowest possible denominator GCD(54, 7).
GCD - 54 / 1 = 53
7 / 1 = 7
