10.2, because it already gave you the r and d, so finding the t would mean dividing, so 402.9 / 39.5 = 10.2, hope that helps!

Step-by-step explanation:

First you subtract the per week (220) from your budget (361)

You get 141

You now divide 141 by 50.15

You come out to 2.81

7.<br>(-3x³)(-2x³y⁴z)(-3z²)÷(4x³z)(-3yz) (-3xyz)

serg [7]

Answer:

$-\frac{x^2y^2}{2}$

Step-by-step explanation:

We have an extremely large equation and are asked to divide it, so let's solve it step-by-step :

Remove the parenthesis to make it easier to read :

$\frac{-3x^3 *2x^3y^4z *3z^2}{4x^3z*3yz*3xyz}$

Multiply the numerators :

$\frac{-18x^6y^4z^3}{4*3*3x^3yyzzz}$

Multiply the denominators :

$\frac{-18x^6y^4z^3}{36x^4y^2z^3}$

Apply the negative rule :

$-\frac{18x^6y^4z^3}{36x^4y^2z^3}$

Cancel the common factor which is 18 :

$-\frac{x^6y^4z^3}{2x^4y^2z^3}$

Apply the addition exponent rule :

$\frac{y^4z^3x^{6-4} }{2y^2z^3}$

Subtract :

$\frac{x^2y^4z^3 }{2y^2z^3}$

Apply the rule for y :

$\frac{x^2y^{4-2} z^3 }{2z^3}$

Subtract :

$\frac{x^2y^2z^3 }{2z^3}$

Cancel the common factor of z^3 :

$-\frac{x^2y^2}{2}$

Write an equality that represents the phrase "the sum of 4 and x is greater than 6." Draw a graph that represents the inequality

Romashka [77]

Answer:

(4+x)>6

See "the sum of 4 and x" means '4+x' and "greater than 6" means the other number ,aka x which equals 4+x, is greater than six. So, the answer comes out to be (4+x)>6.
