Jenny could technically do any of them, first or second. It doesn't matter, as long as you do the same to both sides, the two sides are still equal

I think it's 7 1/2 because you can turn 30 1/4 to 15/2, which simplifies to 7 1/2

7x²=28 I'm not sure about how to do thus problem

OverLord2011 [107]

$7x^{2} = 28$

$x^{2} = \frac{28}{7}$

$\frac{28}{7} = 4$

$x^{2} = 4$

$x = 2$ or $x = -2$

Patrick is constructing the circumscribed circle for △RST. Which construction could be his first step?

Naya [18.7K]

Steps in constructing a circumscribed circle on a triangle using a just a compass and a straight edge.
1) construct a perpendicular bisector of one side of ΔRST.
2) construct another perpendicular bisector of another side of ΔRST
3) the point where the two bisectors intersect will be the center of the circle.
4) place the compass on the center point, adjust its length to ensure that any corner of the triangle will be reached and draw the circumscribed circle.

Ten members of the academic team went to a local restaurant after their contest. Each meal combo that came with soda cost $6.75,

Aneli [31]

Answer:

7 ordered with Soda;

3 ordered with water

Step-by-step explanation:

Given

$m \to$ With water

$n \to$ With Soda

So:

$m + n =10$ --- total

$5m + 6.75n = 62.25$ -- cost

Required

Find m and n

$m + n =10$

Make m the subject

$m = 10 - n$

Substitute $m = 10 - n$ in $5m + 6.75n = 62.25$

$5(10-n) +6.75n = 62.25$

$50-5n +6.75n = 62.25$

Collect like terms

$-5n +6.75n = 62.25 - 50$

$-5n +6.75n = 12.25$

$1.75n = 12.25$

Solve for n

$n = 12.25/1.75$

$n = 7$

$m = 10 - n$

$m = 10 - 7$

$m =3$
