Answer:
4
Step-by-step explanation:
1) cross multiply both sides.
3x^2-24= 2x^2+10
x^2-10x-24=0
x^2-12x+2x-24=0
x(x-12)+2(x-12)=0
(x-12) (x+2)=0
Bring -12 and 2 to the other side. Therefore the value of x are 12 and -2.
Answer:
60%
Step-by-step explanation:
The first step is to divide 27 by 45 to get the answer in decimal form:
27 / 45 = 0.6000
Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage:
0.6000 * 100 = 60.00%
Answer:
The expression is 2.75P.
Step-by-step explanation:
If P represents the initial value and the value increases by 275%, then you can say that it is worth 2.75 times as much as the initial value.
Answer:
The length of the model is 6 inches.
Step-by-step explanation:
The wingspan of the airplane and length of the airplane are a ratio of 4:3
The model is also supposed to be 4:3.
4:3 x 2 = 8:6
Or, 20x12=240
240/8=30
15x12=180
180/30=6.
