Answer: x = 7
`Step-by-step explanation:
Because the figure shows two triangles that are similar. we can write and solve an equation of ratios:
9 cm 72 cm
----------- = -----------
3x - 20 56 cm
Cross-multiplying, we get (3x - 20)(72 cm) = (9 cm)(56 cm) = 504 cm²
Dividing both sides by 72 cm, we get:
3x - 20 = (504 cm²) / (72 cm) = 7
Then 3x - 20 = 7, and 3x = 27. Then x must be 9.
Answer:
4
Step-by-step explanation:
Brackets always mean "DO THIS FIRST!!!"
2+6 = 8
Then, do 3 x 8. That is 24.
24 divided by 4 is 6.
6 - 2 is 4!
Answer:
.
Step-by-step explanation:
The given function is 
.
When this function is translated to the right 7 units and down 9 units, then the equation becomes
.
Always remember that; 
is a transformation that translates the graph of c units to the right and k units down.
The correct choice is the first option.
Let the number be x. Then 1.25x = 325, or x = 260.
20% less than 260 is 0.80(260) = 208
Let x: number of tickets that sold on Friday, y: number of tickets that sold on Saturday night
16x+28y=24232
x+y=1090
x=1090-y,
so 16(1090-y)+28y=24232
17440-16y+28y=24232
12y=6792
y=566. As a result, there will be 566 tickets sold on Saturday night. Hope it help!
