A drama teacher has a budget of $120 to spend on materials to create costumes for a play. She can buy 1 square yard of white mat

Neporo4naja [7]

Inequalities are used to relate unequal expressions

The greatest whole number of square yards the teacher can buy is 4

The inequality is given as:

$8x + 10y \le 120$

When the number of square yards of the white fabrics is 10.

It means that: x = 10

So, we have:

$8 \times 10 + 10y \le 120$

$80 + 10y \le 120$

Collect like terms

$10y \le 120 - 80$

$10y \le 40$

Divide both sides by 10

$y \le 4$

The above inequality means that:

The greatest whole number of square yards the teacher can buy is 4

In the pair of equations bx-6y=18 and 2x-3y=9, b is a whole number. The system of two equations has infinitely many solutions. W

statuscvo [17]

To have infinite solutions, they have to be th esame line

match waht we do know

bx-6y=18
the coefient of y is -6
other one is
2x-3y=9
-3 times 2=-6
times 2nd equation by 2
4x-6y=18
bx-6y=18
b=4

What is the product written in scientific notation?

never [62]

$(1.18\cdot10^3)\cdot(9.1\cdot10^{-6})=(1.18\cdot9.1)(10^3\cdot10^{-6})\\\\=10.738\cdot10^{3+(-6)}=1.0738\cdot10\cdot10^{-3}\\\\=1.0738\cdot10^{1+(-3)}=1.0738\cdot10^{-2}\\\\Used:\\\\a^n\cdot a^m=a^{n+m}$
