Answer: in explanation
Step-by-step explanation:
Rate is simplest form, so 3 napkins for 5 cents.
Unit rate is for 1 x value, so 1 napkin for 0,6 cents.
Answer:
x=6,-4
Step-by-step explanation:
Ok so we know the 2 angles are congruent so you need to set them equal to each other. x^2+5x=7x+24. Then get the x's together so you subtract by 7x to get x^2-2x=24. You would then get 24 on the other side so subtract by 24 to get x^2-2x-24. You then would need to factor the equation out. The factored form would be (x-6)(x+4). Then set it equal to 0 to get 6 and -4.
Answer:
The question is not clearly stated, but I can correctly infer that you wanted to ask the question below:
Out of 150 members, 120 took part, what is the percentage of the total that took part:
Answer:
80%
Step-by-step explanation:
The question is asking us to find what percentage of 150 is 120
Let the percentage of 150 that is 120 be x
x % of 150 = 120
x/100 × 150 = 120
0.01x × 150 = 120
0.01x = 120 ÷ 150 = 0.8
x = 0.8 ÷ 0.01 = 80
∴ 120 = 80% of 150
Wouldn't this be $90-$27 which is 63, 63 being the cost of your earrings
