Step-by-step explanation:

There are a total of 4+1 = 5 ratio units, so each one stands for 65/5 = 13 berries.

  blueberries : strawberries = 4 : 1 = 52 : 13

There are 52 blueberries and 13 strawberries in the bowl.

Answer:

k=-15

Step-by-step explanation:

3(2x-5)=6x+k

open the bracket by multiplying the contents of the bracket by +3

6x-15=6x+k

collect.like.terms(C.L.T)

6x-6x-k=+15

-k=+15 or

-k=15

switch the signs equal to sign(=)

k=-15

Point-Slope form = y-y1=m(x-x1)

Y-6 = -1/3 (x+6)

Slope-intercept form = Y=mx+b

y = -1/3 + 4

The equation of line is y= -2/3x + 2.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

Points: (​-6,6), (6,2)

Slope= (-2 - 6)/( 6 -(-6))

slope= -8 / 12

slope= -2/3

Now, using slope intercept form

y-b = m(x- a)

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

y -6 = -2/3x - 4

y= -2/3x + 2

Hence, the equation of line is y= -2/3x + 2.

Answer:

37

Step-by-step explanation:

let’s say peter’s number is x

(x-12)(-7) = -175

-7x + 84 = -175

-7x = -259

x = 259/7

x = 37

Answer:

The number is 37.

Step-by-step explanation:

-175 ÷ -7 = 25

25 + 12 = 37

You have to work backwards from -175 by doing the reverse of what peter did to get the original number.

10 cups of milk

Step-by-step explanation:

Make a proportion, where x is the number of cups of milk for 165 cookies:

[tex]\frac{2/3}{11}[/tex] = [tex]\frac{x}{165}[/tex]

Cross multiply and solve for x:

11x = 110

x = 10

So, 10 cups of milk are needed to make 165 cookies

Answer:

54%

Step-by-step explanation:

We know Chick-fil-A served 50 sodas in all, 27 of which were regular. The fractional form of this is 27/50. Now, we can convert this to a fraction with a denominator with 100, then a percentage. 27/50 is equal to 54/100.

54/100 is 54%

Answer:

is 54.the max is 100 percent.the percentage of regular sodas is 54 percent.you do this by timing 50 and 27 by 2 to get 100 and 54.

6x - 9y = -12

Step-by-step explanation:

2x - 3y = -4  multiply both sides by 3 by adding paranthesis to represent this

3( 2x - 3y ) = 3 (-4)   Then use distributive property for the left side equation

6x - 9y = -12               Finally just multiply -4 by 3 and you get this equation

Answer:

Sam should have bought 3.09 yards of fabric instead of 2.4 yards

So, Option D is correct.

Step-by-step explanation:

Total fabric needed by Sam = 2.75

According to directions on a sewing pattern they say to buy an extra 12.5%

So, extra fabric would be: 12.5% of 2.75

Solving

[tex]12.5\% \ of \ 2.75\\=\frac{12.5}{100}\times 2.75 \\=0.343[/tex]

Now adding 0.343 into 2.75 to get extra fabric quantity:

2.75+0.343

=3.09

Therefore Sam should have bought 3.09 yards of fabric instead of 2.4 yards

So, Option D is correct.

Answer:5x + 10y = 125

Step-by-step explanation

Number of nickel = x

Number of dime = y

Nickel = 5 cent

Dime = 10 cent

Total value = $1.25

Total value should be converted to cent since both dime and nickel are both in cent

= $1.25 * 100 = 125 cents

Therefore,

5x + 10y = 125 cents

B. Graph 2 represents a proportional relationship, but graph 1 does not.

Step-by-step explanation:

All proportional relationships pass through the origin. Graph 2 does but Graph 1 does not. Additionaly, Graph 2 is a straight line that represents a proportional relationship. Another way to find out if it is proportional is to find the constant of proportionality by dividing the y by the x in different parts of the line. The numbers should all have the same constant of proportionality.

Examples (all found in Graph 2):

15/3 = 5

10/2 = 5

5/1 = 5
