Answer:

10 $x^{2}$ +4x-32

Step-by-step explanation:

5x times 2x =10 $x^{2}$

5x times 4 = 20x

-8 times 2x = -16x

-8 times 4 =-32

10 $x^{2}$ +20x - 16x - 32

20x -16x = 4x

10 $x^{2}$ + 4x - 32

X+2y=9 and x=2y+1<br><br>helppppppppppppppppp meeeeereeer

Answer: y = 2

Step-by-step explanation:

we need to use systems of equations, basically since we know what x equals, we plug that into first equation so:

since x=2y+1,

we can say that:

(2y+1)+2y=9

then we solve this equation,

first we expand the brackets- 2y+1+2y=9,

then we combine like terms- 4y+1=9

then we take 1 away from both sides- 4y=8

then we divided both sides by 4

y=2

Hope this helps xx

What multiplication problem is equivalent to 3 3/8 divide by 3/8

Anni [7]

The expression $3\frac{3}{8}\div \frac{3}{8}$ can be written in multiplication problem as: $3\frac{3}{8}\times \frac{8}{3}$ or $\frac{27}{8}\times \frac{8}{3}$

Step-by-step explanation:

We need to find What multiplication problem is equivalent to $3\frac{3}{8}\div \frac{3}{8}$

We are given: $3\frac{3}{8}\div \frac{3}{8}$

Writing it in multiplication problem.

When division sign is changed to multiplication sign, the fraction is reciprocated.

$3\frac{3}{8}\div \frac{3}{8}$

Converting division into multiplication

$3\frac{3}{8}\times \frac{8}{3}$

or we can write as:

$\frac{27}{8}\times \frac{8}{3}$

So, the expression $3\frac{3}{8}\div \frac{3}{8}$ can be written in multiplication problem as: $3\frac{3}{8}\times \frac{8}{3}$ or $\frac{27}{8}\times \frac{8}{3}$

Anit [1.1K]

Since we must save 50 meals for volunteers, the real amount we are giving away is 700 meals in 12 hours.

700/12 = 58.3333...

10*58.333.. = 583.333....

Since we can't serve 1/3 of a person, we take 583. Hope this helps!

What does that equal

son4ous [18]

Answer:

$3-\sqrt{10}$

Step-by-step explanation:

We are given an expression and are asked to find what it equals. We can see that the two square roots are being multiplied, therefore they follow the same standard as any multiplication problem, do as followed :

$\sqrt{5} *\sqrt{2}$

$\sqrt{10}$

Since a square root and constant number are different terms, we cannot combine them together, therefore leave as is :

$3-\sqrt{10}$
