We can use slope , point formula
y-y1=m(x-x1)
m is a slope=(y2-y1)/(x2-x1)=(-10-(-7))/(2-1)=-3
for example, we take the point (1, -7)
y-(-7)=-3(x-1)
y+7=-3x+3
y=-3x-4
Equivalent fractions can be found by multiplying numerator and denominator by the same number.
for example : 2/5 * 3/3 = 6/15......2/5 and 6/15 are equivalent. Just like 2/5 * 4/4 = 8/20......2/5 and 8/20 are equivalent...so basically, if u multiply the numerator by a certain number, and the denominator by that same number, u will get an equivalent fraction.
Now to ur problem...
x 54
------ = -----
7 42
now look at ur denominators....7 x what = 42 ? 7 x 6 = 42...so u have multiplied the denominator by 6....so u would have to multiply the numerator by 6.....or divide by 6....54/6 = 9.....or 9 x 6 = 54. So that missing value is 9.
9/7 = 54/42
check..
9/7 * 6/6 = 54/42 (equivalent)
Answer:
37/5
Step-by-step explanation:
7 2/5 = 37/5
5x7=35
35+2=37
Multiply the whole number and denominator then, add the numerator and put the sum of that back ontop of the denominator
Example:
W N/D DxW=X X+N= Y
W N/D = Y/D
The answer is B) <span>(60 - 4x)(50 + 2x) = 2,800
The revenue without any change in price is:
$60/student x 50 students = 3,000
Every price drop reduces the price/student by four, so the first term, which describes the fee per student, is 60 - 4x
Every price drop also increases the number of students by two, so the second term, which describes the number of students, is 50 + 2x</span>
Answer:
2,920 ounces
Step-by-step explanation:
To find this, just multiply:
292 × 10 = 2,920
So, 2,920 ounces are needed
Hope this helps :)
