Answer: [C]: 50.2 m²
__________________________

Since: Area of a circle: A = $\pi$ * r² ';

And: A = $\pi$ = 3.14 * 4² = 3.14 * 16 ;

We know that the area will be a bit more that ( 3 m * 16 m = 48 m²) ;
_____________________________________________________
And, Answer choice: [C]: 50.2 m² ; is the closest value.

Solve for x and y 2x+7=3y-1

zlopas [31]

To solve for x and y, isolate each variable and simplify your equation:

Solve for x:
2x+7=3y-1 (Subtract 7 on each side)
2x=3y-8 (Divide by 2 on each side)
x= $\frac{3y}{2} -4$

Solve for y:
2x+7=3y-1
2x+8=3y (Add 1 on each side)
$\frac{2x}{3} + \frac{8}{3}$ =y (Divide by 3)
y= $\frac{2x}{3} + \frac{8}{3}$

Alina spent no more than $45 on gas for a road trip. The first gas station she used charged $3.50 per gallon and the second gas

Paraphin [41]

Answer: 3.50x + 4.00y ≤ 45

0 < y < 11.25

Step-by-step explanation:

$3.50x + 4.00y \leq 45\\\\\\\text{Subtract 3.50x from both sides:}\\4.00y\leq -3.50x+45\\\\\\\text{Divide everything by 4.00 (to isolate y):}\\\dfrac{4.00y}{4.00}\leq \dfrac{-3.50x}{4.00}+\dfrac{45}{4.00}\\\\\\y\leq-0.875x+11.25\\\\\\\text{Both x and y must be greater than zero, so:}\\0$

You are trying to recreate flubber because you are obsessed with that movie and you thought it was the coolest. you take 70% sli

german

Let $x$ be the amount (gal) of the 40% slime solution you end up using. You want to end up with 120 gal of the 50% solution, so that you would use $120-x$ gal of the 70% solution.

You want the final solution to consist of 50% slime, or 60 gal of slime. Each gal of the 40% solution contributes 0.4 gal of slime, while each gal of the 70% solution contributes 0.7 gal of slime. This means

$0.4x+0.7(120-x)=0.5\cdot120=60$

$\implies0.4x+84-0.7x=60$

$\implies24=0.3x$

$\implies x=80$

so the answer is B.
