Answer:
£289.20
Step-by-step explanation:
13:2 = x:16 or 13/2 = x/16
cross multiply: 208 = 2x
simplify: x = 104
16 blue tiles x £2.80 each = £44.80
104 white tiles x £2.35 each = £244.40
44.80 + 244.40 = £289.20
A = L * W
A = 320
L = W + 4
320 = W(W + 4)
320 = W^2 + 4W
W^2 + 4W = 320
W^2 + 4W + 4 = 320 + 4
(W + 2)^2 = 324
W + 2 = (+-) sqrt 324
W = -2 (+-) 18
W = -2 + 18 = 16 ft <== this is the width
W = -2 - 18 = -20....not this one because it is negative
L = W + 4
L = 16 + 4
L = 20 ft <=== this is the length
in summary...the width is 16 ft and the length is 20 ft
Answer:
Step-by-step explanation:
S+J+M=36
J=S-2 or J=x-2
M=S-16 or M=x-16
Hey!
To solve this problem, we'll first start by creating an equation.
<em>Our Created Equation :
</em>

Now we'll solve it step by step to find the answer.
So we should begin by multiplying the to portion of our fraction.
<em>400 x 60 = 24,000</em>
Next, we divide our answer by 100, since that is the next step to our equation.
<em>24,000 ÷ 100 = 240</em>
So, our answer is...
<em>Paul has already saved</em>
$240.00 <em>of the $400.00 he must pay for a new bike.</em>
Hope this helps!
