Maribel sold 20% of the cupcakes she made. If she sold 35 cupcakes, then she made how many
cupcakes in all.

Answer:

(-5, -8); the missing value is -8

Step-by-step explanation:

First, you need to simplify the given equation to isolate y

1: -3x + 7y = 5x + 2y (Given)

2: 7y = 8x + 2y (Add 3x to both sides)

3: 5y = 8x (Subtract 2y from both sides)

4: y = 8/5x (Divide both sides by 5)

Now, you can use this to solve for the missing y in value set (-5, y)

where y = 8/5x and x = -5,

y = 8/5(-5)

y = -8

so, the missing value is -8

Answer:

Circumference of the circle = 34.54 inches

Step-by-step explanation:

Explanation

Given that diameter of the circle

                                    d = 11inches

The radius of the circle    

                                [tex]r = \frac{d}{2} = \frac{11}{2} = 5.5[/tex]

Circumference of the circle

                              = 2πr

                             = 2×3.14×5.5

                           = 34.54

Final answer:-

Circumference of the circle = 34.54 inches

Answer:

24

Step-by-step explanation:

multiply the length (4) times the width (6) and you get the area (24)

Answer:

n=36

a=403

d=395-403=8

an=a+(n-1)d

a36=403+(36-1)395

Answer:

the answer is actually 123

Step-by-step explanation:

Answer: 6.68km/litre

Step-by-step explanation:

Distance(d) = 187km ( to 3 significant figures)

Petrol(p) = 28litres ( to 2 significant figures)

A number, x, rounded to 1 significant figure is 200

Write down the error interval for x

Calculating the lower and upper bound for both 'd' and 'p'

Upper bound 'd' = 187.5km

Lower bound 'd' = 186.5km

Upper bound 'p' = 28.5km

Lower bound 'p' = 27.5km

Therefore,

Petrol consumption (C) = d/p

Upper C = 187.5 / 28.5 = 6.57894

Lower C = 186.5 / 27.5 = 6.781818

Accuracy answer for C = (6.57894 + 6.781818) / 2 = 6.680379

= 6.68km/ litre ( to 3 significant figures)

To achieve a reasonable level of accuracy, the upper and lower bounds of P and D was used to calculate C, which was then averaged.

Using 3 significant figures ensure that we capture the C better, instead of early rounding.

Answer:

B

Step-by-step explanation:

vertical line test means draw lots of vertical lines and see if they pass through two or more points

if they do, the graph is not a function

for example, x= 0 passes through two points

so it is not a function

Step-by-step explanation

A relation is any set of ordered pairs. A function is a set of ordered pairs where there is only one value of y for every value of x.

Step-by-step explanation:

its the most logical one to me

Answer:

A

Step-by-step explanation:

Answer:

-x+y= -14 (get this equation to where you can easily plug it in for a variable)

y= x -14

5x +6y =26 (plug the value above in for y and then solve)

5x + 6 (x-14) = 26 (use the distributive property)

5x +6x - 84 = 26 (combine like terms on the left side)

11x - 84 =26 (add 84 to both sides)

11x = 110 (divide both sides by 11 to isolate the x-variable)

x= 10 (this is the value for x. plug it into the easier equation and solve)

-(10) +y = -14

y= -4

(10, -4) (this is the solution for the system of equations)

Answer:

apples: 6/8 = $0.75 per apple

pears: 1.25/1 = $1.25 per pear

peaches: 1.50/1 = $1.50 per peach

bananas: 4/6 = $0.67 per banana

"price per unit" means that you want to find out how much a single one of the product costs. you figure it out by dividing the price by how many there are.

Answer:

B.) 10.5

Step-by-step explanation:

Use ratios, but be careful.

AE/AD = AB/AC

14/18 = x/(x+3).

14x+42 = 18x

42 = 4x

x = 10.5

The value of x in the given figure is 10.5 so, option B.) 10.5 units is correct.

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b

or

[tex]\dfrac{a}{b}[/tex]

Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.

Using ratios;

AE/AD = AB/AC

14/18 = x/(x+3).

14x+42 = 18x

42 = 4x

x = 10.5

Thus, option B.) 10.5 units is correct.

#SPJ2

Answer:

Step-by-step explanation:

p1=(2,4)   and p2=(5,6)

use slope formula to find the slope

[m=y2-y1 / x2-x1)]

m=6-4 / 5-2

m=2 / 3

use point-slope formula [y-y1=m(x-x1)] with either given point and work but  since they have a 5 and a 6 in the their answer use p2

y-6=2/3(x-5)

the last choice looks good
