Answer:

Step-by-step explanation:

6/9+x=7/10

x=7/10-6/9

when adding fractions both denominators must be equal, we’ll make them 90

x=(7/10)(9/9)-(6/9)(10/10)

x=63/90-60/90

x=3/90, the greatest divisor of 3 and 90 is 3 so divide both the numerator and denominator by 3

x=(3/3)/(90/3)

x=1/30

How to solve 45y to the second power plus 15y minus 10 ?

Lerok [7]

Answer:

Either y = $\frac{-2}{3}$ or, y = $\frac{1}{3}$

Step-by-step explanation:

We have to solve the following quadratic equation

45y² + 15y - 10 =0

Now, dividing both sides with 5 we get, 9y² + 3y -2 =0

Hence, to solve the above equation we have to factorize the left-hand part of the equation.

So, 9y² + 3y - 2 =0

⇒ 9y² +6y -3y -2 =0

⇒ (3y +2) (3y -1 ) =0

⇒ Either (3y +2) =0 or (3y -1) =0

⇒ Either y = $\frac{-2}{3}$ or, y = $\frac{1}{3}$ (Answer)

den301095 [7]

Answer:

Using proportions, the pizza parlor should expect 20 breadsticks and 25 calzone orders if there were 100 total orders.

Step-by-step explanation:

Orders:

Salads 3

Pizzas 8

Sides of breadsticks 4

Pepperoni calzones 5

Total orders: 20

Proportion of sides breadsticks=4/20=0.2

Proportion of pepperoni calzones=5/20=0.25

For 100 total orders:

Sides of breadsticks=0.2(100)=20

Pepperoni calzones=0.25(100)=25
