It’s 4 because y is a variable plus any number in front of a variable makes it a coefficient
Answer:
2
Step-by-step explanation:
We can put this into an equation:
10/x=5
first, we multiply x on both sides:
10=5x
and then we divide by 5 on both:
2=x
so the answer is 2
Answer:
x = 7
y = 2
Step-by-step explanation:
In the above question, we are given 2 equations which are simultaneous. To solve this equation, we have to find the values of x and y
x + 3y = 13 ........ Equation 1
x - y = 5...........Equation 2
From Equation 2,
x = 5 + y
Substitute 5 + y for x in Equation 1
x + 3y = 13 ........ Equation 1
5 + y + 3y = 13
5 + 4y = 13
4y = 13 - 5
4y = 8
y = 8/4
y = 2
Since y = 2, substitute , 2 for y in Equation 2
x - y = 5...........Equation 2
x - 2 = 5
x = 5 + 2
x = 7
Therefore, x = 7 and y = 2
Answer:
Median = 36
Step-by-step explanation:
To calculate the median number of miles Jenna cycled, we must first rearrange the numbers. The rearranged numbers are:
28, 31, 36, 36, 42, 48, 52
The middle number is 36
The median it therefore = 36
Answer:
3/10
Step-by-step explanation:
=4/7 + 9/70 - 4/10
=l.C.M of 7 , 70 and 10 =70
=4/7 .10/10 +9/70 -4/10 .7/7
=40/70 +9/70 -28/70
=40+9-28/70
=49-28/70
=21/70
=3/10
