Answer:
The answer is 3x+2
Step-by-step explanation:
2(3x-1)-3x+4
I did distributive property on 2(3x-1) how I did that was I multiplied 2 times 3x which is 6x (2 times 3x=6x). Then I multiplied 2 times -1 which equals -2 (2 times -1=-2).
new expression:
6x-2-3x+4
I combined all the numbers with the variables (6x and -3x) and by subtracting both of them you get 3x (6x-3x=3x). After that you combine -2 and 4 which equals 2 (-2+4=2).
This is now the final expression (your answer):
3x+2
The shirt cost 3 times $35.
The shoes cost 5 times $28.
3 * $35 = $105
5 * $28 = $140
$105 + $140 = $245
They cost $245.
The diffrence of 37 and B.
Answer:
A linear function is a function whose graph is a straight line on plotting.
Step-by-step explanation:
The general form of such equations is f(x) =ax+b, where x is dependent variable and y is independent variable.
Moreover, linear equation has one independent variable and one dependent variable.
Answer:
The perimeter is the distance around the triangle. Given the ratio, the perimeter using the ratio is;
= 3 + 4 + 5
= 12 units
a. <u>12 units</u> = 240 cm
The perimeter in centimetres is 240cm and in ratio is 12 units so they are equivalent.
b. <u>1 unit </u>= 20 cm
If 12 units are to 240 cm, 1 unit is;
= 240/12
= 20 cm
c. Length of red side;
Red side has length of 5 units. 1 unit is 20 cm.
Length in cm is;
= 5 * 20
= 100 cm
