50*8=400
400+175=575
it subtracted 575 on the last round
Answer:
No, Angela is not correct.
As the method Jim was performing will also lead to the solution.
Step-by-step explanation:
We are given first equation as:
Ax + By = C
Second equation is:
Dx + Ey = F
Jim solved the equation as:
He begins by multiplying equation (1) by D and equation (2) by A.
and so by subtracting both the equations he will obtain a value of y.
and then put the y-value in any of the given two equations to obtain the value of x.
Angela Method:
you should have multiplied equation (1) by E and equation (2) by B.
and when she will subtract both the equations she will get the value of x first and then when she will put the value of x in any of the given equation she will obtain the value of y.
But both will get a value for x and y.
Hence, the method Jim was performing was also correct.
17/ is the best one for the answer bc it can be
Answer:
- 90/11
Step-by-step explanation:
- Multiply 8 with 11 = 88
- Add that with 2 = 90
- That is your nominator and 11 is denominator.
- Because the faction is negative, put a negative sign.
Answer:
12 choices
Step-by-step explanation:
There are 3 possible flavors Zoe can choose from: vanilla, chocolate, and strawberry.
Meanwhile, there are 4 possible toppings Zoe can choose from: walnuts, sprinkles, and chocolate fudge and cookie crumbs.
Each flavor can go with each topping, so we just multiply these two numbers together:
3 * 4 = 12
Zoe has 12 choices.
