Answer:
10/14, 15/21
Step-by-step explanation:
WE are given a ratio 5/7
To find equivalent ratios it is sufficient to multiply both numerator and denominator by the same number
Let us take 2,3 for example.
When we multiply both numerator and denominator by 2, value does not change.
Hence we get equivalent fraction.
So 10/14 is one such fraction.
Next is multiply by 3
15/21 is another fraction.
You would change the denominator and get the lowest common denominator. Thos would be 30. You would do 11/6 x 5/5 = 55/30. Then do 3/5 x 6/6 = 18/30. Then add 55/30 + 18/30 = 73/30 and simplify.
Answer:
The number of hamburgers sold was 139 and the number of cheeseburgers sold was 278.
Step-by-step explanation:
Let
x -----> the numbers of hamburgers sold on Thursday
y -----> the numbers of cheeseburgers sold on Thursday
we know that
----> equation A
----> equation B
Substitute the equation B in equation A and solve for x



Find the value of y

therefore
The number of hamburgers sold was 139 and the number of cheeseburgers sold was 278.
Answer:
Option (B) is correct.
Allison biweekly gross pay is $942.31
Step-by-step explanation:
Given annual salary offered to Allison = $24,500.
We have to calculate Allison biweekly pay that is pay Allison got for 2 weeks
To calculate biweekly we first find Allison weekly pay then multiply it by 2.
We know there are 52 weeks in a year.
So, weekly salary offered to Allison
(approx)
Biweekly salary will be = 2 × weekly salary
= 2 × 471.15
= 942.307(approx)
Thus, Allison biweekly gross pay is $942.31
Answer:
x + y = 90 - - - (1)
y = 1/4x - - - - (2)
Step-by-step explanation:
x = larger acute angle
y = smaller acute angle
Recall:
A right angle measures 90°
Sum of angles in a triangle = 180°
y = 1/4x
Hence :
90 + x + y = 180
x + y = 180 - 90
x + y = 90 - - - (1)
y = 1/4x - - - - (2)
Put y = 1/4x in (1)
x + 1/4x = 90
1.25x = 90
x = 90 / 1.25
x = 72
x + y = 90
72 + y = 90
y = 90 - 72
y = 18
