Answer: 6 orchestra tickets were purchased

Step-by-step explanation:

orchestra purchased tickets = x

balcony purchased tickets = y

ou purchase nine tickets

total cost of $720

x + y = 9

90x + 60y = 720

----------------------------------------

x + y = 9 (*-60)

90x + 60y = 720

----------------------------------------

-60x - 60y = -540

90x + 60y = 720 (+)

----------------------------------------

30x = 180

x = 6

Factor 75t2 + 12.<br> 3(5t + 2)2<br> 3(25+2 +4)<br> 3(251-4)
frosja888 [35]

Answer:

75t^2+12=3(25t^2+4)

Option C)

Step-by-step explanation:

Here we are given with the expression 75t^2+12

The GCF of 75t^2 and 12 is 3

Hence we take 3 as GCF and bring it in front of the bracket.

3(25t^2+4)

It can not be factorise furthure  as there is no GCF of 25 and  also there is no rule for sum of squares so that we may apply it on this. Hence the answer would be

3(25t^2+4)

Option C)

RoseWind [281]
Fraction form: x=7/12

Steps:

64^4x-3

2^6(4x-3)=2^-4

6(4x-3)=-4

4x-3=-2/3

4x=7/3

X=7/12

I think of a number. If I divide the sum of 6 and the number by 3,the result is 4 more than one quarter of the number. Find the
Alex17521 [72]

Answer:

24

Step-by-step explanation:

Let the number be x.

Sum of the number and 6: 6+x

Divide it by 3: \frac{6+x}{3}

Result is 4 more than one quarter of the number:

\frac{6+x}{3} =4+\frac{1}{4} x

Multiply both sides by 12:

\frac{6+x}{3}\cdot \:12=4\cdot \:12+\frac{1}{4}x\cdot \:12

Simplify:

4\left(x+6\right)=48+3x

Expand:

4x+24=48+3x

Subtract 24 from both sides:

4x+24-24=48+3x-24

4x=3x+24

Subtract 3x from both sides:

4x-3x=3x+24-3x

x=24

The number is 24.
