Answer:

Step-by-step explanation:

Given

$\sqrt{qrv+11}$ = 30 ( square both sides to clear the radical )

qrv + 11 = 900 ( subtract 11 from both sides )

qrv = 889 ( divide both sides by rv )

q = $\frac{889}{rv}$ → A

A first number plus twice a second number is 11. Twice the first number plus the second totals 31 find the numbers

Serhud [2]

X + 2y = 11
2x + y = 31

x = 11 - 2y

2(11 - 2y) + y = 31
22 - 4y + y = 31
3y = - 9
y = - 3

x = 11 - 2(-3)
x = 11 + 6
x = 17

A pizza restaurant charges a flat fee for a plain cheese pizza. There is an extra charge for any additional toppings. The cost o

Lapatulllka [165]

Answer:

The y-intercept is the flat fee for the pizza - $5. The slope is the charge for each additional topping - $.50

Step-by-step explanation:

c=.5m+5

y=mx+b - slope intercept formula

In the slope-intercept formula, the 'b' is the y-intercept. We know that would be the flat fee because there is no variable attached to it.

In that formala, m is the slope and is attached to a variable, x. This problem uses the variable m instead of x, but we can see that the slope for .5m would be .5. Thus, that's the charge for the toppings. Hope that helps!

three miners esch dup up 3 diamonds. the weight of the diamonds were 5,13,12,4,9,8,15,210, and 6 ounces of a piece. each of jack

Nataliya [291]

The total weight of Nico's diamond is 564 ounces

<h3>Weights</h3>

The weights of the diamond are given as:

5, 13, 12, 4, 9, 8, 15, 210, and 6 ounces

<h3>Total weights</h3>

Start by calculating the total weights

$Total = 5+13+12+4+9+8+15+210+6$

$Total = 282$

The above sum represents the total weights of Jack's diamonds.

So, the total weights of Nico's diamond is calculated as:

$Nico = 2 \times 282$

$Nico = 564$

Hence, the total weight of Nico's diamond is 564 ounces

What is the equation of the graphed line written in standard form

weqwewe [10]

Ax+by=c

First you'll find the equation of the graphed line in slope-intercept form, y = mx+b, and then from there we'll convert it into standard form, ax+by = c.
