Answer:

-15/4 > -3 3/8

Step-by-step explanation:

I converted -15/4 into a mixed number with a denominator of 8. First, I made it a mixed number (-3 1/4) and then I converted it to eighths (-3 2/8). Compared to -3 3/8, -15/4 is larger.

{y,x} = {10,-5}

Step-by-step explanation:

sorry if this dont make sense

solve equation [2] for the variable y

y = 4x +30

plug this in for variable y in equation [1 ]

(4x+30) +3x= -5

solve [1] for the variable x

7x= - 35

x= - 5

by now we know this much

y= 4x+30

x= - 5

use the x value to solve for y

y=4 (-5) + 30 = 10

solution

{y,x} = {10,-5}

Assume that y is directly proportional to x. Use the given x-value and y-value to find a linear model that relates y and x.

steposvetlana [31]

Answer:

Step-by-step explanation:

To find a linear model, you need to use the formula y = kx and solve that for k. k is the constant of variation, also known as the slope of a line. Hence, the word "linear".

If y = kx and y = 1010 and x = 5, then

1010 = 5k so

k = 202

The linear model, then, is

y = 202x

A supplier sells 2 and 1/4 pounds of mulch for every 1 and 1/3 pounds of gravel. The supplier sells 172 pounds of mulch and grav

polet [3.4K]

Because ratios can be written as fractions
$\frac{mulch}{2.25}=\frac{gravel}{1.33}$

172 = $\frac{mulch}{2.25}+ \frac{gravel}{1.33}$
172 - $\frac{mulch}{2.25}$ = $\frac{gravel}{1.33}$
76.44 mulch = x amount of gravel = 172
Gravel = 172 - 76.44
= 95.56

Bond [772]

Answer:

Company C

Step-by-step explanation:

To find the cost of each bear, you must divide each price by the amount of bears. The prices are shown below:

For company A, each bear costs $2.87.

For company B, each bear costs $2.89.

For company C, each bear costs $2.85.

So, the best buy for the team would be Company C.
