Equation: g(4)=25-3(4), answer: g(4)=13
Items bought in total:
4 brothers X two hot dogs and one bag of chips=
4X3=
12.
Hot dogs- x, chips- y.
4y + 8x= $18.20
Chips= $1.25 each so
4($1.25) + 8x= $18.20
5 + 8x= $18.20
8x= $18.20-5
8x= $13.20
x= $13.20/8 [13.20 divided by 8]
x= $1.65
This means that one hot dog= $1.65.
If you’re unsure what to write as the answer I’d suggest that you put all the working out down in your copy/notes.

I don't know but these can be really difficult
good luck
(1) The value of x is 25
(2) The measure of ∠CBD is 60°
Explanation:
(1) The given two angles are vertical angles. Since, vertical angles are equal, we can add the two angles to determine the value of x.
Thus, we have,

Subtracting 5x from both sides, we have
Adding 10 to both sides , we have,

Thus, the value of x is 25.
(2) It is given that the measure of ∠ABC = (x+7)° and ∠CBD = (2x+14)°
Since, these two angles are supplementary angles and supplementary angles add upto 90°
Thus, we have,

Simplifying, we get,



Thus, substituting the value of x in ∠CBD = (2x+14)° to determine its value.

Thus, the measure of ∠CBD is 60°
