B is the correct answer as we use the x- intercept of the intersection and substitute it for x in the equations.
So 2(1)+2 = -(1)+5
2+2 = -1+5
4=4
So the second option
Answer:
130
Step-by-step explanation:
3.8+13.2=17
8x17=136
136-6=130
Answer:
7
Step-by-step explanation:
2 x (3-1) + 3
Evaluate using PEMDAS
Parenthesis
Exponents
Math and Division ( left to right )
Addition and Subtraction ( left to right )
2 x (3-1) + 3
According to PEMDAS we do the operations inside of the parenthesis first
3 - 1 = 2
We now have: 2 x 2 + 3
Next we do exponents
There are no exponents so let's move on to multiplication and division
There is indeed multiplication so we do it
2 x 2 = 4
We now have: 4 + 3
Finally we do the addition
4 + 3 = 7
The answer is 7
First we want to find how much an individual biscuit costs.
If 5 biscuits costs 30p, then
5 x 1 biscuit = 30p
divide both sides by 5
1 biscuit = 6p
If one biscuit costs 6p, and we want to know how much 7 biscuits cost, then:
7 x 6p =42p
7 biscuits costs 42 p
