X = boy count
x + 14 = girl count
x +x +14 = 86
2x + 14 = 86
2x = 72
x = 36
x + 14 = 50
There are 36 boys and 50 girls. Hope this helps!
Answer:
the y intercept is 3 for both functions,
the y intercept is the same
Step-by-step explanation:
y = x+3
is in the form y= mx+b where m is the slope
the slope is 1
the y intercept is 3
graph pick 2 points to find the slope
to get from one point to the next
we go up 1 and to the right 3
m = rise/ run = 1/3
the y intercept is 3
the slopes are not the same, the slope of R > S
the y intercept is 3 for both functions, the y intercept is the same
Answer:
x=1.5$x=-3/7
Step-by-step explanation:
(2x-3)(2*2+7x-1)
(2x-3)(3+7x)
6x+14x^2-9-21x
x=1.5$x=-3/7
Solving a linear equation, we can conclude that each tin costs £0.75
<h3>How much does a tin of beans cost in pounds?</h3>
First, we know that Ed buys one box of eggs for £2.20.
Also two packs of bacon for £2.80 each.
And two tins of beans for X each.
Then the total cost is:
C = £2.20 + 2*£2.80 + 2*X
Now, we also know that when he pays with £10, he gets a change of £0.70.
Then we can solve the linear equation:
£10 - (£2.20 + 2*£2.80 + 2*X) = £0.70
£2.20 - 2*X = £0.70
£2.20 - £0.70 = 2*X
£1.50 = 2*X
£1.50/2 = X = £0.75
In this way, we can conclude that each tin costs £0.75
