Answer:
Step-by-step explanation:
ok teacher make these kind of questions very hard but they are very easy here we go
if there is only 6 boys that means there are 14-6=8 girls
so the ratio of girls to boys is 8:6
know when it says all students we have to include girls too
so in a class of 14 there are 6 boys and 8 girls
14:8 is our answer
Answer:
x = 3
y = 2
Step-by-step explanation:
Equations
7x - 7y = 7
-4x - 7y = - 26 Multiply both sides of the equation by - 1
-1(-4x - 7y = - 26)
4x + 7y = 26
Solution
Add the two equations together
7x - 7y = 7
4x + 7y = 26
11x = 33 Divide by 11
11x/11 = 33/11
x = 3
4x + 7y= 26 Use this equation to solve for y. Use x = 3
4*3 + 7y = 26 Combine the left
12 + 7y = 26 Subtract 12 from both sides
12 - 12 + 7y = 26 - 12 Combine
7y = 14 Divide by 7
7y/7 = 14/7
y = 2
Answer:
-7
Step-by-step explanation:
-9 - (-2)
If there is a negative sign in front of a negative number in parenthesis, then that makes it a positive number.
-9 + 2 = -7
Here in an idea:
lets say his total is repreented with the variable t.
lets say the number of bags of apples is represented by a.
t = a + 2
unless there is missing info.
hope this helps!
