Matt saves 7 dollars every week in order to buy a guitar. Write an equation, using x for the independent variable and y for the dependent variable. If he saved for 19 weeks, how much money did he save?

Answers

Answer 1

Answer:

y = 7x

y = $133

Step-by-step explanation:

x = independent variable

y = dependent variable

y = 7x

Where,

y = total amount saved

x = number of weeks

7 = constant

When x = 19

y = 7x

y = 7 * 19

y = 133

y = $133

Pls help me solve for x. And thank you so much

Answers

Answer:

x=11

Step-by-step explanation:

given -2 + 4x = 6(x-4) the objective is to get the variable (x) on one side and the constant on the other using inverse operations

-2 + 4x = 6(x-4)

step 1 distribute the 6 to x and -4

6*x=6x

6*-4=-24

now we have

-2 + 4x = 6x - 24

step 2 add 24 to each side

-2+24=22

-24+24 cancels out

now we have 22+4x=6x

now we want to get rid of the 4x

to do so we subtract 4x from each side

4x-4x cancels out

6x-4x=2x

now we have

2x = 22

step 4 divide each side by 2

22/2=11

2x/2=x

we're left with x = 11

Erica has 1 5/8 cups of yogurt to make smoothies. Each smoothie uses 1/3 of a cup of yogurt. What is the maximum number of smoothies that Erica can make with the yogurt?

Answers

Answer:

4 smoothies.

Step-by-step explanation:

We divide 1/3 into 1 5/8  ( which is 13/8).

=  13/8 * 3

= 39/8

= 4 7/8

Maximum number = 4.

Find the midpoint of A and B where A has coordinates (-3,-5) and B has coordinates (4,4).
Brainliest if you want :)

Answers

Use the midpoint formula,

[tex]\left( \dfrac{x_1+x_2}{2} , \dfrac{y_1+y_2}{2} \right)[/tex]

where x₁ = -3, x₂ = 4, y₁ = -5, and y₂ = 4.

[tex]\left( \dfrac{x_1+x_2}{2} , \dfrac{y_1+y_2}{2} \right) \implies \left( \dfrac{-3+4}{2} , \dfrac{-5+4}{2} \right) = \left(0.5, -0.5\right).[/tex]

So, the midpoint of A and B is (0.5, -0.5). It should be in the first quadrant.

Log 8 1/32 is equaled to

Answers

Answer:

I think the answer wold be -5/3 or -1.666666667 .

The value of the given expression is,

[tex]log_8 \frac{1}{32}[/tex] = -3/5

The given logarithmic expression is,

[tex]log_8 \frac{1}{32}[/tex]

Since we know that,

The power to which a number must be increased in order to obtain additional values is referred to as a logarithm. The easiest approach to expressing enormous numbers is this manner. Numerous significant characteristics of a logarithm demonstrate that addition and subtraction logarithms may also be represented as multiplication and division of logarithms.

We can write the given expression as,

[tex]log_8 \frac{1}{32}[/tex] =   [tex]log_8 32^{-1[/tex]

          = - [tex]log_8 32[/tex]                  [ [tex]log_a b^x = x log_a b[/tex]]

          = - [tex]log_{2^3} 2^5[/tex]

          =  - [tex]\frac{3}{5} log_{2} 2[/tex]                 [ [tex]log_{a^y} b^x = \frac{x}{y} log_a b[/tex]]

          = -3/5                       [  [tex]log_{a} a = 1[/tex]]

Hence,

[tex]log_8 \frac{1}{32}[/tex] = -3/5

At a soccer tournament 12 teams are wearing red shirts, 6 teams are wearing blue shirts, 4 teams are wearing orange shirts, and 2 teams are wearing white shirts. For every 2 teams at the tournament, there is 1 team wearing ____

Answer:

For every 2 teams at the tournament, there is 1 team wearing RED SHIRTS

Step-by-step explanation:

Step 1

We add all the teams together

Red + Blue + Orange + White

12 + 6 + 4 + 2

= 24 teams

Step 2

We have 12 red teams.

If we find the ratio of red team to total number of teams

= 12 :24

= 1:2

Therefore, for every 2 teams at the tournament, there is 1 team wearing RED SHIRTS
