Answer:
The cost of sweatshirt is 12$
Step-by-step explanation:
so we are going to make 3 equations and solve it using the substation method
First- We know the price of the shirt is two times more so w = 2h
Second we know that the the tee shirt is 4 dollars less then the pair of shoes so t = h − 4
Third we take the combined of Brads purchases 3w + 5t + 2h =136
w = 2h
t = h − 4
3w + 2h + 5t = 136
So to solve we are going to to the sub method
3(2h) + 2h + 5(h-4) = 136 - just re written, now we get rid of the ( )
6h + 2h + 5h -20 = 136 - Now we need to move the -20 and add it too 136
6h + 2h + 5h = 156 - Now sum up the H's
13h = 156 - Now divide 13 by 156
h= 12
so the Cost of a sweatshirt is 12 dollars
Answer:
59.04°
58.31 inches
Step-by-step explanation:
The solution triangle is attached below :
Since we have a right angled triangle, we can apply trigonometry to obtain the angle ladder makes with the ground;
Let the angle = θ
Tanθ = opposite / Adjacent
Tanθ = 50/30
θ = tan^-1(50/30)
θ = 59.036°
θ = 59.04°
The length of ladder can be obtained using Pythagoras :
Length of ladder is the hypotenus :
Hence,
Hypotenus = √(adjacent² + opposite²)
Hypotenus = √(50² + 30²)
Hypotenus = √(2500 + 900)
Hypotenus = 58.309
Length of ladder = 58.31 inches
Answer:
(5/x)-(18y)
Step-by-step explanation:
First write the expression (5/x) and then the second expression (18y) the write the difference, so basically a subtraction. (5/x)-(18y)
