Answer:
x = 20
Step-by-step explanation:
x^2 - 4x - 8 = 8
x^2 - 4x - 8 + 8 = 8 + 8
x^2 - 4x = 16
x (x - 4) = 16
x - 4 = 16
x - 4 + 4 = 16 + 4
x = 20
Answer:
1.26885245902 or rounded to $1.27 per pound.
Step-by-step explanation:
you can just divide 3.87/3.05 to see how much each pound costed. if you needed to round to the nearest cent, you would round up to 1.27.... or if not, keep it at 1.26885245902.
then to check your work, you can just multiply (1.26885245902) by (3.05) to get the total amount she had spent.
Okay so since their are two numbers which are 32 and 1 the decimal would be .32 so she read 32 more pages
The slope can be worked out by the equation:
So with the coordinates (1,2) and (-2,4):
x1 = 1 y1= 2 and
x2 = -2 y2 =4
Note that x1 and y1 use the same coordinate, vice versa with x2 and y2.
Tip: The equation can be y1-y2 and x1-y2 too (have a think why)
So the answer is 2/-3, which is the same as C)
-2/3
Answer:
The price for adults would be $44.20
Step-by-step explanation:
There are 2 ways to solve this problem
1) You can multiply 26 by 0.7 and then add That to 26
Or
2) You can just multiply 26 by 1.7
You get the same answer for both ways
So first way
26*0.7 is 18.2
Now add 18.2 to 26
You’ll get 44.20
Second way
26*1.7. I multiplied by 1.7 becuase its a markup of 70 percent, th kid’s price is already 100 percent and for adult its an extra 70 percent so the china ally we’re paying 170 percent for the adult ticket
Now multiplying by 170 percent is basically the diamond 1.7
so 26*1.7 is 44.2
